How to Repair a Crack Over a Door
LESLIE: Now we’re heading on over to Iowa where Brian has a crack on the wall that keeps on coming back. Tell us what’s going on.
BRIAN: Well, yeah, I built this home about six years ago and noticed it within the first year, really, that in just one of my bedrooms, I have a crack that comes up from my bedroom going into my bathroom door. And it kind of almost goes up probably close to 2½ feet, 3 feet. And it comes and goes, depending on the year. I’ve finished over it a couple of times on both sides of the wall, into the bathroom and here, and have tried to refinish over it and it keeps coming back. And my builder looked at it. Can’t quite figure it out and …
TOM: This is what we call a Groundhog Day home improvement project, Brian, because it just keeps happening over and over again, right?
BRIAN: Yeah, yeah. It just – yeah, just originally I just tried to cover it up and make it look better and …
TOM: Alright. Well, here’s the thing. You’ve got a very normal crack in a wall there. Cracks often form over doors, like exactly what you’re describing there, because that’s a weaker part of the wall. And for whatever reason, you had some settlement in your house and it caused this crack to open up. The fact that you’re spackling it is not going to solve it. It solves it for a season but it won’t solve it permanently.
What you need to do is you need to sand the area of the crack pretty well, because I want you to get out – get rid of all that extra spackle you’ve been putting on there. Then I want you to add a layer of fiberglass drywall tape, which is sort of like a netting. It’s a bit sticky-backed. And then I want you to spackle over the fiberglass netting – over the fiberglass tape – on both sides. Start with a narrow bead of spackle and then open it up wider and wider and wider. And that, on both sides of the wall, will make that wall strong enough to stand up to the movement that will happen the next time the wall expands or contracts.
You can’t just spackle it, because you’re not really doing anything to bridge that gap. You bridge that gap with the tape, spackle over the tape, now you’ve got a permanent repair. Does that make sense?
BRIAN: Yeah, that makes sense.
TOM: Alright. Good luck with that project, Brian. Thanks so much for calling us at 888-MONEY-PIT.
