Quick Answer
Yes, it is possible to remove a wall anchor from a wall in most cases. The process will depend on the type of anchor and wall material. Generally it involves loosening the screws or bolts holding the anchor in place, then tapping the anchor itself to break the grip of the retaining device from the wall. Care should be taken not to damage the surrounding wall material.
What is a Wall Anchor?
A wall anchor, also called a wall plug, is a device that is inserted into a hole drilled or driven into a wall. It contains some sort of retaining mechanism that grips the inside of the wall when a screw or bolt is tightened into it. This allows an object to be securely fastened to the wall.
There are several common types of wall anchors:
Plastic Expansion Anchors
These have a plastic sleeve with wings that spread outward when a screw is inserted into the anchor. The wings press against the inside of the hole, gripping the wall material firmly.
Threaded Drywall Anchors
These anchors have threads on the outside that dig into drywall material when they are turned as they are driven into a hole. The screw tightens into the anchor’s inner sleeve.
Toggle Bolts
A toggle bolt has spring-loaded “wings” that fold together when inserted into a hole. When the screw is tightened, the wings spring open behind the wall material, bracketing the wall between the wings and the bolt head.
Sleeve Anchors
Designed for use in concrete or brick, a sleeve anchor has an outer threaded sleeve and an inner cone-shaped expander. Tightening the screw pushes the expander into the sleeve, spreading it and causing it to grip the wall material.
Molly Bolts
This type is designed specifically for hollow drywall walls. It has a hex-shaped expander head connected to a threaded sleeve. When tightened, the expander head opens up against the backside of the drywall.
Removing Wall Anchors
The exact technique for anchor removal will vary depending on the type. Here are some general guidelines:
Plastic Expansion Anchors
For plastic expansion anchors, first fully loosen or remove the screw from the anchor. This will allow the wings to relax their grip on the wall material. Use a flathead screwdriver or pick to try prying or popping the anchor free. If needed, use a hammer to tap lightly on the anchor to break it loose.
Threaded Drywall Anchors
Like plastic anchors, first remove the screw fully from a threaded drywall anchor. Use pliers to grip and unthread the anchor counterclockwise to remove it from the drywall.
Toggle Bolts
Toggle bolts must first have their screws removed to allow the spring-loaded wings to retract. Carefully slide the unscrewed bolt back through the hole to retract the wings before gently pulling the entire anchor out.
Sleeve Anchors
To remove a sleeve anchor, unscrew the bolt completely which will relieve the pressure on the spreader inside the sleeve. Use pliers to grip and twist the anchor counter-clockwise to unthread it from the hole. Hitting it gently with a hammer may help break the grip.
Molley Bolts
First remove the screw from a molly bolt. Grip the bolt head with pliers and detach it from the metal sleeve by twisting it. Then lightly hammer the recessed sleeve to break its grip and pry it out with a screwdriver.
Factors That Make Anchor Removal Difficult
While removing most anchors is straightforward, some situations can complicate the process:
– Tightly gripping wall materials like solid concrete make it hard to pop anchors free.
– Old or corroded anchors may have parts that break when trying to extract them.
– Attempting to reuse an anchor hole rarely works well since removal damages the grip. New anchors should be used in fresh holes.
– Screws stuck firmly in the anchor resist unscrewing. Penetrating oil or a screw extractor can help loosen stuck screws.
– Limited workspace can make swinging a hammer awkward. Use care not to damage surrounding areas.
– Attempting to salvage or reuse stubborn anchors risks damaging the wall. It may be better to abandon them in place.
Tips for Removing Wall Anchors
Follow these tips to safely and effectively remove wall anchors:
– Always fully loosen or remove any screws from the anchor before attempting removal.
– Start by gently prying on the anchor to try and break its grip before hammering. This reduces wall damage.
– Use an appropriate tool like a screwdriver or pliers to grip and twist the anchor free when possible.
– Apply penetrating oil to stubborn, stuck screws and allow time for it to soak before trying to unscrew them.
– Hammer firmly but carefully on the anchor body if needed, using a block of scrap wood to prevent marring walls.
– For tough cases, use a drill to grind away the anchor’s threads to make it easier to detach.
– Minimize drywall damage by avoiding large hammers. Use a drywall hammer or rubber mallet instead.
– Wear eye protection when hammering anchors to avoid injury from debris.
– If an anchor absolutely won’t budge, leave it in place and patch over it. Forcing it could damage the wall.
Precautions When Removing Anchors
Keep these precautions in mind when tackling anchor removal:
– Turn off power before removing any anchors around electrical wiring to avoid a hazard.
– Take care not to damage existing plumbing or gas lines hidden behind walls.
– Wear safety glasses to prevent eye injuries from flying debris. Use a dust mask too if hammering may create dust.
– Clear any items near the wall before swinging tools to prevent unintended damage.
– Check for potential electrical, plumbing or other hazards before drilling into walls. Use a stud finder to be sure.
– Use appropriate tools for the job. Improvised tools like household screwdrivers can damage anchors or walls.
– Don’t use excessive force trying to extract a stubborn anchor. Seek alternatives like abandoning it or using a drill instead.
– Make sure the wall material can support any load before removing its anchor. Temporarily brace heavy objects first if needed.
– Follow all manufacturer instructions for anchor removal if available. Proper technique varies.
– Take your time and apply patience when removing anchors. Forced or hasty efforts often lead to unnecessary damage.
Alternatives to Removing Anchors
In instances where anchor removal proves too difficult or risks wall damage, consider these alternatives:
– Cut off any protruding hardware – Sawing off the exposed bolt or screw can eliminate snag hazards if the anchor must stay.
– Drill out the anchor – Using a bit slightly larger than the anchor diameter will allow you to drill through and destroy anchored hardware.
– Drive it in further – Some anchors can be tapped deeper into the wall if the protrusion is problematic.
– Patch over the anchor – Using drywall compound or mortar to cover the anchor is the easiest solution, though it leaves the anchor in place.
– Move object position – Adjusting the location of attached items like cabinets to use new anchor sites avoids stubborn anchors.
– Use a specialty removal tool – Tools like screw extractors, stud bolts or impact anchors can attach and yank out stuck anchors.
– Hire a handyman – Those with proper tools, experience and skills may have the best luck with stubborn anchors in risky locations.
Conclusion
Most wall anchors can be successfully extracted by following a removal process appropriate for the anchor type. This involves fully loosening retaining screws or bolts, then dislodging the anchor through prying, unthreading, tapping and pulling. Using care to avoid marring walls or damaging contents, while wearing protective gear for safety, will aid the process. In some difficult situations, alternatives like drilling, patching or hiring a professional may be better options than forcing out a stubborn anchor. With the right approach and technique, removing unwanted wall anchors presents a manageable task for minor wall repairs or furniture rearrangements.
