Changing your fixings without damaging the existing wall
11 October 2025 · 21 min read · by Walensky
You've just purchased a stunning artwork, but here's the thing: your old fixings are no longer suitable and you're looking at your pristine wall with that dull anxiety of ruining everything. This paralyzing fear of drilling in the wrong place, leaving unsightly marks, or even worse, weakening your partition.
You can already imagine the large holes when you remove the old wall plugs, those stubborn glue stains that refuse to budge, or even this paint that flakes around the old fixing points. Not to mention the unpleasant feeling that your wall will soon look like a honeycomb.
You keep putting it off, you hesitate, you keep your old paintings “while you find a solution”. Maybe you’ve even tried some tips found on the internet that have backfired: filler that doesn’t hold, paint that doesn’t cover perfectly, or unsuitable fixings that have ended up giving way.
Rest assured: it’s not a lack of talent on your part. The real reason for these failures? Most advice ignores the specific type of your wall and, above all, doesn’t take into account the fact that each fixing change is unique depending on the old system used.
By the end of this article, you will master the foolproof method for replacing any fixing without leaving the slightest trace, and you will even learn how to transform your old fixing points into a decorative asset for your new installation.
Why does your wall deserve this particular attention now?
Your wall tells a story, and every mark, every imperfection bears witness to the evolution of your decorative taste. Waiting any longer risks the old fixings deteriorating further and making renovation more complex. It's like a cavity: the longer you wait, the more invasive the treatment becomes. Today, you have the opportunity to start from a healthy base and create a durable hanging system that will enhance your future artistic favorites.
💡 Customer testimonial: "I lived with a wobbly painting for 3 years because I was afraid of re-drilling the holes. When I finally dared, I discovered that my old molly plugs were slowly pulling out - the plasterboard was even starting to crack! In one afternoon, I completely renewed everything and my living room regained its elegance." - Sarah, interior architect
Conversation with a decor expert
The golden rule of fixing changes: It’s better to make a methodical intervention today than an emergency repair tomorrow. In 2-3 hours of careful work, you get a result that will last for years and sublimate each new artistic acquisition.
What’s really happening to your wall (and why it’s not your fault)
You might recognize yourself in these three situations: your paintings mysteriously tilt after a few months, you sometimes hear a suspicious little "click" when you pass near the wall, or you notice fine cracks that appear around the fixing points. These signals reveal that your old fixing system is no longer suitable.
What’s really happening? The materials in your wall evolve over time : humidity, temperature variations, and the micro-vibrations of everyday life cause the fixings to "work". The problem is therefore not your initial installation, but the natural evolution of the materials.
It's exactly like a shoe that deforms with use : even perfectly fitted at first, it needs maintenance or replacement to regain its optimal comfort.
The first hidden cause: the effect of "material fatigue"
Contrary to what one might think, it’s not the large paintings that damage walls the most, but the unsuitable fixings that create concentrated "stress points". A fixing that is too small in a large hole generates more damage than a robust, well-sized system.
Imagine an umbrella opened in a strong wind : it’s not the gusts that break it, but the repeated small pressures on poorly designed weak points.
Result: you live with this underlying anxiety that "it’s going to let go", and you no longer dare to change your paintings. In reality, a well-adapted fixing will give you back this creative freedom and decorative serenity.
🔍 Revealing test: Gently place your ear against the wall near your fixings and tap lightly with your finger. A hollow or metallic sound indicates that the fixing "moves" in its housing - this is the perfect time to renovate!
The illusion of the "system that has always worked"
Many people think that a fixing that has held for years is necessarily reliable. In reality, old systems degrade invisibly : fixings gradually loosen, plaster cracks micro-millimeter by micro-millimeter.
It’s like an elastic band that is stretched daily : it looks identical, but its resistance decreases imperceptibly until the day it breaks abruptly.
Consequence: when you add a new painting, even a light one, it’s the straw that breaks the camel’s back. The good news? Identifying this phenomenon allows you to anticipate and create a truly durable system.
The invisible factor: incompatibility of fixing systems
Here’s what no one tells you: mixing different types of fixings on the same wall creates unequal tensions. A molly fixing next to a fischer fixing is like having a bike wheel more inflated than the other.
Carefully observe your walls: micro-cracks often appear between two different fixings, never around a homogeneous system that is properly installed.
Impact on your daily life: your paintings never align perfectly, you spend your time straightening them, and you lose that visual harmony that makes all the difference in a well-decorated interior.
🔍 The 3 signals that don’t lie:
- The "frame dance": Your paintings move when someone passes near the wall = the fixings "pump" in their housing
- The small piles of white dust: Traces of plaster or drywall at the foot of the wall = micro-disintegration around the anchors
- Progressive asymmetry: A perfectly straight frame becomes tilted in a few weeks = uneven dilation of the fixings
The trigger element: the emotional charge of your walls
The deciding factor is your emotional connection to your space. A wall that inspires confidence releases your decorative creativity, while a "problematic" wall unconsciously restricts you. It's the domino effect: a reliable fixing encourages you to invest in beautiful paintings, which beautifies your daily life and strengthens your well-being at home. To identify this factor in yourself: ask yourself if you hesitate before buying a new painting for fear of technical complications.
The universal rule of durable fixing: A well-prepared wall welcomes everything, a neglected wall rejects everything. Check this by imagining your next artistic crush: do you immediately see where to hang it, or do you first look for the "safe zones"?

The 3-Step Method for an Invisible Fixing Change
Rest assured: you won't turn your living room into a construction site. This method follows the natural logic of wall restoration, like a dentist treating a tooth: first clean, then rebuild, finally protect. At each step, you'll see the progress and gain confidence. By the end of the process, you'll have trouble finding the location of the old fixings !
🗺️ Overview of your transformation: Step 1 = Diagnosis and clean removal (30 min), Step 2 = Repair and preparation (45 min), Step 3 = Installation of the new system (45 min). Progression logic: we erase the past, we prepare the future, we install the present.
Step 1: The liberating diagnosis - Dismantling without damage
This first step is the most reassuring because you finally discover the actual condition of your fixings. It's like opening the hood of a car: no more agonizing assumptions, just objective observations! Once this step is complete, you'll feel a real sense of relief: the "mystery" of your wall is solved.
Your allies for this step
- Wide spatula (8-10 cm): Resembles a plastering knife with a flexible blade. Used to cleanly remove residue without scratching the paint. Find it in hardware stores, choose one with an ergonomic handle and stainless steel blade (avoid plastic which breaks). Why not a simple knife? Too rigid, it scores instead of sliding.
- Long-nose pliers: This tool resembles scissors with fine, toothed jaws. Allows you to grip stubborn dowels while exerting controlled traction. Choose a model with a non-slip coating on the jaws. Visible impact: extraction without paint chips.
- Soft metal brush: Opt for a brush with brass bristles (golden color) rather than steel (too aggressive). Removes plaster residue without digging into the surface. Recognize the good quality by its flexibility: the bristles should flex under finger pressure.
Now, let's move on to practice with method
Gentle dismantling
Releasing the paintings: Place each painting down while supporting the frame with one hand as the other releases the fixing. This precaution avoids the sudden pull that can tear the dowel out with a piece of wall. The technical detail: tilt the painting slightly towards you to clear the fixing system without forcing.
⏱️ Time: 5 min per painting | ✅ Successful when: No audible "crack", fixings visible and intact | ⚠️ Attention: Never pull downwards - fixings are designed to withstand gravity, not lateral tearing
Removing the dowels: Use the pliers to firmly grip the head of the dowel and perform a slow rotating movement before pulling. This rotation "disconnects" the dowel from its housing by breaking the micro-adhesions. Keep the spatula within reach to protect the wall surface during the effort.
⏱️ Time: 3-5 min per dowel | ✅ Successful when: The dowel comes out whole, the hole is clean and regular | ⚠️ Attention: If it resists, stop and move on to the softening step (a few drops of warm water in the hole, wait 5 min)
Cleaning the residue: Brush each hole gently with the soft metal brush, using circular motions. The goal is to remove small fragments and plaster dust, not to dig further. Finish with a passage of the spatula to smooth the edges.
⏱️ Time: 2 min per hole | ✅ Successful when: Clean edges, visible and clean hole bottom | ⚠️ Caution: Do not insist if you see the structure of the wall (brick, cinder block) appear - this is normal in some cases
✅ Quality control step 1: Your wall has clean and regular holes, without chips or residue. You can run your finger over each hole without catching any roughness. If some holes seem "too large", that's perfect - it will facilitate repair. Next goal: transform these openings into a perfectly smooth surface!
Step 2: Invisible reconstruction - Pro-level repair
This is where the magic happens: you will not only erase all traces of the past, but also improve the solidity of your wall. This step is more rewarding because you see your wall "regenerate" before your eyes. The snowball effect: each well-repaired hole makes you want to take care of the next one with even more attention.
Your reconstruction tools
- Quick-setting patching compound: Choose a white or gray paste that is ready to use, sold in a tube or 1kg pot. Avoid powders to mix (critical proportions). Find it in the "wall preparation" section of hardware stores. Quality criterion: must remain malleable 10-15 minutes after application. Impact: durable repair and easy sanding.
- Flexible putty knife (6 cm): Stainless steel blade with ergonomic plastic handle. The principle: flexibility allows you to perfectly follow the contours of the hole and obtain a perfectly flat surface. Recognize good quality by the flexibility of the blade, which must flex without deforming. Visible result: smooth surface without thickness.
- Sandpaper grit 180: Fine grit that erases micro-defects without creating visible scratches. Finer than grit 120 (too abrasive), more effective than grit 240 (too soft). Ideal format: 23x28 cm sheet that you can fold. Benefit: finish that blends perfectly into the existing wall texture.
Methodical reconstruction
Applying the compound: Take a knob of compound on your putty knife and apply in a cross pattern on the hole, then smooth with circular motions slightly overlapping the healthy wall. This technique ensures adhesion and prevents air bubbles. The secret: exert firm but progressive pressure so that the compound "grips" the bottom of the hole.
⏱️ Time: 2 min per hole | ✅ Successful when: Slightly domed surface, well-adhered compound, no bubbles | ⚠️ Caution: Do not smooth too much - keep a slight relief for the final sanding
Strategic drying time: Let dry for 2-4 hours depending on humidity. Compound ready? It becomes lighter and harder to the touch without crumbling. Meanwhile, prepare your new fixings and measure the future locations. This forced pause is ideal for planning the rest serenely.
⏱️ Time: 2-4h drying | ✅ Successful when: Uniform color, resistant to finger pressure | ⚠️ Caution: Don't rush it with a hairdryer - risk of cracking
Finishing sanding: Sand with sandpaper in circular motions, starting with the edges then the center. The goal: to obtain a perfectly flat surface that blends into the existing wall. Dust off with a dry cloth to reveal the final result.
⏱️ Time: 3 min per repair | ✅ Successful when: Smooth to the touch, no visible demarcation | ⚠️ Caution: If you see the original compound appear (different color), that's perfect - continue gently
🎯 Validation step 2: Your wall has a homogeneous surface, without demarcation between repaired areas and original wall. Touch test: run your hand over the entire area - no roughness should catch. Visually, repairs are invisible under normal lighting. You are ready for final installation!
Step 3: The prestige installation - New system for eternity
This is where you move beyond the amateur level to achieve professional finishing. What's the difference between a DIYer and an expert? The expert anticipates future constraints and chooses their fixings to last 20 years. Visualize the final result: a mounting system so reliable that you'll never think about it again, freeing your creative energy for what really matters: choosing and arranging your works of art.
Next-generation fixing system
- Metal expansion anchors: Choose anchors with a zamak body (anti-corrosion alloy) and progressive expansion. Unlike plastic anchors that "break" the wall, these adapt gently. Sizes: 6mm for tables up to 5kg, 8mm beyond. Where to find them: professional fixing section. Investment that counts: guaranteed resistance for 15-20 years.
- Self-centering concrete drill bit: Drill bit with a centering tip that prevents slippage during drilling. Diameter exactly adapted to your anchors (6 or 8mm). The magic principle: the tip guides the drill bit, impossible to drill crooked. Recognize it by its distinct tapered tip. Concrete benefit: perfect holes from the first try.
- 60 cm spirit level: Precision tool with 3 vials (horizontal, vertical, 45°). Professional quality: replaceable vials and precise graduation. Economical alternative: laser level on smartphone + support. Impact on the result: perfect alignment that impresses even perfectionists.
Final installation
Precision marking: Measure and mark your new anchor points with pencil, using the level to guarantee perfect alignment. Double check with the triangle rule: the distances between points must form equal triangles. This step determines the final aesthetics - take your time.
⏱️ Time: 15 min for 4-6 points | ✅ Successful when: Clear marks, alignment verified twice, consistent measurements | ⚠️ Attention: Check for horizontal even if the wall seems straight - houses "move"
Controlled drilling: Drill at a moderate speed while keeping the drill perfectly perpendicular to the wall. Let the drill bit do the work without forcing - excessive pressure crushes the plasterboard. Regularly vacuum up dust to maintain perfect visibility of the depth.
⏱️ Time: 2 min per hole | ✅ Successful when: Clean hole, uniform depth, no chips around | ⚠️ Attention: If you feel sudden resistance, you may be touching a structure - that's normal, continue gently
Final anchor installation: Insert each anchor by screwing it in slightly to initiate expansion, then tighten gradually until firmly resistant. The secret: expansion must occur gradually to perfectly conform to the structure of the wall. Final test: the anchor should not move even under moderate traction.
⏱️ Time: 3 min per anchor | ✅ Successful when: Flush anchor, firm resistance, no play | ⚠️ Attention: Do not tighten to the maximum in one go - risk of breaking the internal expansion
🏆 Final expert check: Your new fixings support a test pull (pull firmly by hand), the alignment is perfect from all angles, and the anchors sit flush harmoniously. Ultimate test: temporarily hang a picture and step back - immediate satisfaction confirms success!
Wise progression rule: Master each step perfectly before moving on to the next. Objective criteria for progress: step 1 = clean extraction without damage, step 2 = invisible repairs to the touch, step 3 = fixings that don't move a millimeter. Ambition without haste guarantees a result you'll be proud of for years.
You have just crossed the line between approximate DIY and professional finishing. Now, let's discover the expert subtleties that transform a good job into a discreet masterpiece. These details make all the difference and give you that edge that impresses without anyone knowing why.
🎯 Little-known pro tip: After installation, lightly touch up the heads of the anchors with a small brush and a bit of matching paint - they literally become invisible. Why is this so effective? The eye detects contrasts, not shapes. By unifying the colors, you visually erase the fixings. Concrete example: a white wall with white anchors seems to have no fixings, even up close.
"But what if I get the measurements wrong for my new pictures ?"
"I'm afraid of drilling in the wrong places and having to start all over..."
I perfectly understand this apprehension - it's the number one fear of all my clients ! In reality, this concern reveals your commitment to quality, which is perfect. Here's the reassuring secret: with the method you just learned, even a "mistake" can be repaired invisibly in just 20 minutes. You now master the complete cycle: removal → repair → new installation. This skill definitively frees you from the anxiety of the "hole in the wrong place". On the contrary, it gives you the boldness to try several layouts until you find the perfect one.
💡Liberating advice: Before drilling permanently, trace your locations with a pencil and live with that temporary marking for 24 hours. Look at your walls under different lighting, visually test with pieces of paper the size of your pictures. This "full-size" validation eliminates 99% of later regrets.
The 5 pitfalls that turn success into disaster
After supporting hundreds of people in their fixing projects, I have identified the recurring errors that ruin a job that was well started. These pitfalls are insidious because they seem logical at the time. Fortunately, knowing them allows you to avoid them completely.
- 🚫 The "while I'm at it" temptation: Wanting to treat the entire wall at once instead of focusing on the necessary area. Why is it tempting? You tell yourself you'll finish faster. Concrete consequence: fatigue that leads to rushed finishes, and a work area too vast to maintain quality. Alternative solution: treat in sections of 2-3 fixings maximum, with a break between each. This error affects the vast majority of beginners!
- ⚠️ The impatience of drying: Sanding the filler before it is completely dry to "save time". It's human to want to see the result quickly! Disastrous result: the fresh filler crumbles and creates craters that are impossible to repair properly. Corrected method: use this time to clean your tools and prepare for the next step. Patience = guaranteed perfection.
- 🔧 The error of the overly powerful drill: Use the maximum speed to go faster. Apparent logic: faster is more efficient. Real trap: excessive speed causes the drill bit to overheat, which burns the drywall and creates uneven holes. Proven technique: moderate speed with constant but gentle pressure. Your wall deserves this delicacy.
- 📏 The trap of "approximate measurement": Relying on the eye rather than measuring instruments. Seems obvious when you're "used to it"... Disaster is assured: millimeter misalignments that accumulate and give a crooked appearance to the whole. Foolproof solution: systematic double-checking with a level and measuring tape. Precision = elegance.
- 💪 The excess of force "to be sure": Tighten the anchors to the maximum to make them hold better. Laudable intention of solidity! Perverse effect: over-expansion that cracks the inside of the wall and weakens the whole structure. Correct technique: tighten until a firm resistance is felt, then a maximum of one quarter turn extra. Moderation surpasses brute force.
🛡️ Your quality safety net: At each step, check these 4 points: 1) Immaculate cleanliness of the area (no dust or residue), 2) Respect for the announced drying times (patience rewarded), 3) Fixings that do not budge under manual traction, 4) Perfect alignment verified with a level. Warning signs to watch out for: abnormal noise during drilling (immediate stop), plaster that crumbles when sanding (too soon), anchor that continues to spin in the void (hole too large).
Frequently asked questions: everything you still want to know
Allow a relaxed half-day (3-4h) for careful work, including drying times. Possible optimization: treat repairs in groups - while the first ones dry, prepare the next ones. Concrete example experienced: "I did my living room on a Saturday morning, lunch break during drying, and finalization in the afternoon with a feeling of accomplishment."
Between €25 and €45 all inclusive to treat 5-8 fixings, depending on the quality chosen. Clever detail: prioritize quality tools (€30) over consumables (€15) - you will reuse them. Surprise savings: this method avoids repainting the entire wall (saving €80-€150 depending on the surface). An investment that pays for itself from the first use!
Excellent question that reveals your demanding nature! This method even surpasses the expectations of the most demanding because it follows professional standards. Tangible proof: repairs become detectable only in raking light 10cm from the wall. Tip that makes the difference: invite your partner to validate each step - participation transforms the critic into a benevolent ally.
Absolutely not, on the contrary! The drill is the safest tool in modern DIY - automatic shut-off system, ergonomic design, controlled power. Reassuring advice: start with a test on a piece of drywall or wood to get acquainted with the tool. Real-life experience: "I was afraid of the drill, now I wonder why I waited so long - it's easier than a blender!"
Yes, by simply adapting the type of wall anchor. Universal principle: drywall = expansion anchors, concrete = hammer-in anchors, stone = chemical anchors. The advantage of this method? The steps remain the same, only the final tooling changes. Simple recognition test: if a 3cm nail goes in easily = drywall, if it resists = concrete/stone. Guaranteed adaptation for 95% of domestic situations.
Your new decorative freedom begins now
Imagine yourself in a few weeks: you enter your living room and what immediately strikes you is the perfect harmony of your walls. Your paintings seem to have always been there, as if they were part of the original architecture. No more stress when you crave a new work of art - you know your wall will welcome it perfectly. Your guests compliment you on your "innate sense" of decoration, without suspecting the technical mastery behind this apparent ease.
But this transformation goes far beyond pure aesthetics. You have acquired a valuable autonomy : that of evolving your interior according to your desires, without depending on a professional or fearing "disasters". This technical confidence has a positive effect on your decorative creativity - you dare to try things you would never have attempted before.
The beauty of this method? You have mastered it for life. Moving, renovating, new artistic crush: you now know that your walls will never be a constraint on your projects. You only have one gesture left to accomplish: take out your tools and turn this knowledge into tangible reality.
🌟 Your transformation begins with the first gesture: You now have all the keys to create the interior you dream of. It wasn't a talent issue, just a matter of method. Your next decorative masterpiece awaits you - and now, you know exactly how to offer it the setting it deserves!
