Drywall Crack Keeps Coming Back in Port Coquitlam?
Open 24 hours
Failed tape, a bent corner bead, compound that never dried and moisture behind the wall: here is what each one looks like, how to tell them apart and how we fix it.
A crack that comes back in the same spot after you paint over it is rarely a filler problem. Something under the surface is still moving, or never set properly. We at Texora Painting & Drywall do drywall repair in Port Coquitlam and across the Tri-Cities, and these are four causes worth checking.
1. Is failing tape why the crack keeps coming back?
Often, yes: failing tape is a common reason. Stress cracks along corners, tape joints and the line where a wall meets the ceiling are common in older homes and homes that have settled. If the tape under the compound has let go, the joint is still free to move, and filling over it only hides the crack for a season.
The fix is to cut out the failing tape, apply new tape and compound, feather and sand, then prime. That removes the crack rather than covering it.
2. Is a damaged corner bead behind the crack?
It can be, because a dent at a corner often bends or loosens the bead under the compound.
Outside corners are usually reinforced with a metal or plastic corner bead under the mud, and that bead keeps the corner straight. A dent or impact at a corner often goes past the surface compound and bends or loosens the bead itself. Filling over a damaged bead without addressing it tends to leave the corner slightly crooked and cracking again.
If the corner is visibly dented, bowed or pulling away from the wall, the bead needs addressing before any compound goes on. A loose bead shows as a hairline crack up the full corner, and it gets cut back, replaced and re-taped.
3. Did the drywall compound dry all the way through?
Joint compound needs to dry all the way through, typically 24 hours per coat, before the next coat, sanding or primer. A patch that looks dry on top can still be damp underneath. Sanding or priming too early is a common reason hairline cracks show up weeks later, after the paint is already on.
We apply 2 to 3 thin coats, feathering each one wider than the last, and sand between every coat and after the final one.
4. Is there moisture behind the drywall?
If the crack comes with drywall that bulges or feels soft when pressed, paper facing that crumbles, or a musty smell with no obvious cause, the problem may be moisture rather than movement.
Water-damaged drywall is repaired only after the source of the moisture is fixed. Then the section is either cut out and re-sheeted, or treated, sealed with stain-blocking primer and re-mudded in place. Our water damage drywall repair page covers that case.
5. Should you fix a drywall crack yourself or hire it out?
A few nail holes or a small ding make a fair first DIY patch: fill, let the compound dry all the way, sand, prime. Hiring makes sense once the repair has to disappear: a crack along a corner or taped joint that keeps coming back, a bent corner bead, a patch on a knockdown, orange peel or stipple texture, or anything water-related.
You do not need to hire a drywaller separately.
One of our crews repairs the drywall, re-applies matching texture (we test a sample area first on unusual textures), then primes and paints. Or we leave the wall paint-ready if you would rather do the painting yourself. If you want the painting done too, see interior painting in Port Coquitlam.
6. What does the warranty cover on a drywall repair?
Drywall tape or patches that fail because of how the work was done are covered under the workmanship warranty of up to 5 years named in your written estimate. Moisture coming through the roof, drainage or building envelope, and structural movement are not.
If a repair cracks again, call us before another contractor touches it so it stays covered. The warranty page has the full terms.
