TV Mount Pulling Away From the Wall in Lexington, KY

Part of our complete guide: How to Mount a TV on Any Wall.

Most mounts that come off a wall give plenty of warning first. The screen starts leaning forward a little more each month, a gap opens between the bracket and the wall, or a hairline crack appears in the drywall just above the plate. Those are not cosmetic problems. They are the wall telling you the fasteners are losing their grip, and the time to act is while the TV is still on the wall.

A wall mount fails for one of a small number of reasons, and almost all of them come back to what the bracket was screwed into. Here is what actually goes wrong, what to do the day you notice it, and what a proper re-mount looks like.

1. Drywall Anchors Holding a Load They Cannot Hold

This is the cause we see most often. Plastic expansion anchors and the cone-shaped self-drilling anchors that come in a hardware-store kit are fine for a picture frame or a shelf bracket. A television on an arm is a very different load, because the weight hangs away from the wall and tries to rotate the top of the bracket out of it.

Drywall is gypsum between two sheets of paper. An anchor in it can only hold as well as the material crumbling around it, and under a constant pulling load it slowly enlarges its own hole. That is why these failures are gradual: the anchor works for months, then the screen is visibly tilted, then one day the top of the bracket is standing off the wall.

2. Lag Screws That Missed, or Barely Caught

A mount lagged into solid framing is a strong installation, but only if the screws are actually in the framing. A lag that catches the edge of a stud, or one that found the drywall next to it, feels tight when it is driven and holds far less than it appears to.

Length matters just as much. A lag needs enough thread biting into the wood behind the drywall to be worth anything, and a short screw in a thick wall assembly may only reach a fraction of an inch into the stud. Our guide to what is behind the wall covers how the layers stack up in local homes.

3. Walls That Need Their Own Hardware

Plenty of Lexington walls are not wood studs and drywall, and each one fails differently when it is treated as though it were.

• Plaster and lath. Common in older homes. Lath is thin and splits, so the load belongs on the framing behind it or on properly sized toggles.
• Metal studs. A lag screw has nothing to thread into. Metal studs need toggle-style hardware sized for the load, not wood lags.
• Hollow concrete block. An anchor that lands in a void rather than a web will pull out. Placement matters as much as the anchor.
• Brick and stone veneer. Mortar joints and veneer behave differently from solid masonry, and the wrong sleeve anchor works loose.

We have separate guides for plaster and lath, metal studs and drywall with no stud where you need one.

4. The Bracket, the Bolts and the Torque

Sometimes the wall is fine and the hardware is not. A full-motion arm puts far more leverage on the wall plate than a flat bracket, so an arm mount on marginal fasteners fails sooner and more dramatically. Mixing hardware from an old mount with a new one is another regular culprit, because the bolt that came with a different bracket may be the wrong thread or the wrong length for the back of your set.

Over-tightening causes its own failure: a lag driven hard enough to crush the drywall face has already lost some of its clamping grip, and an anchor cranked past its limit has stripped its own hole. Under-tightened is no better, because a bracket that can move at all will work itself looser every time the arm is swung. If you are reusing an existing mount, our guide to reusing a TV wall mount covers what to check before it goes back up.

5. What to Do the Day You Notice It

Take the weight off the wall. On most mounts the screen lifts off the wall plate, and doing that with a second person is far easier and safer than doing it alone. Set the TV somewhere flat and padded, screen facing in, rather than leaning it against furniture where it can slide.

Do not retighten a loose anchor and call it fixed. Once a hole in drywall has been enlarged, driving the same screw back into it gives you less holding power than it had before, not more. The same is true of a stripped anchor. The fastener has to move to sound material, which usually means new fixing points and a repaired wall.

6. What a Proper Re-Mount Involves

A re-mount is a little more work than a fresh install, because the wall has already been damaged. We find the framing, assess how much of the wall around the old holes is still sound, and repair or patch what needs it before anything is hung. Where there is no framing in a usable position, the fix is hardware rated for that wall type rather than a hopeful anchor.

Then the mount goes back up on fasteners sized for the screen and the style of bracket, gets leveled, and the cables are dressed properly. If the old mount was undersized or its hardware is incomplete, replacing it is usually cheaper than working around it — our guide to what to look for in a TV wall mount explains what matters.

Pricing

A re-mount is priced the same as an installation, by screen size: 32" $129, 43" $129, 50" $129, 55" $129, 65" $139, 75" $229 and 85" $279. That covers mounting the TV, leveling, basic cable management and all wall hardware. The mount itself is separate — flat $35, tilting $45, full-motion $125 (32–55") — or we will reuse your existing mount at no charge if it fits your set and its hardware is all there. Service within 20 miles of Lexington is free. Richmond is our home base, so it is free too.

If the screen is visibly tilting, if you can see daylight behind the wall plate, or if there is cracked drywall above the bracket, treat it as urgent. Lexington TV Guys re-mounts televisions across Lexington, Richmond and the surrounding counties, and we would rather look at it while it is still on the wall.
