Settlement cracks at corners and seams cut, taped, and finished so they stay closed.
If you live in North Texas and you have cracks in your drywall, you are not unusual, your house is not falling down, and you are also not going to fix them permanently by filling them with compound. Understanding why is worth five minutes, because it changes what you should ask for.
We sit on expansive clay soil. It swells when it takes on water and shrinks when it dries out, and the difference in volume between a wet August and a dry one is enough to move a foundation measurably. The house rides on that. The drywall, being brittle, telegraphs it at the weakest points.
Blackland clay is the culprit. It is high-plasticity soil that changes volume with moisture content, and the moisture content around your foundation changes with the season, with your irrigation, with the trees in your yard drinking from the soil, and with whether your gutters are dumping water at the corner of the slab.
The result is that a foundation does not sit still. It moves a little, seasonally, more or less forever. This is normal for the region.
Drywall cracks where stress concentrates, which is why they are so predictable:
We are drywall people and we will not pretend to be foundation engineers. But we see a lot of houses, and there are patterns worth knowing about. If you have cracks that are wider than about a quarter inch, or doors that have stopped latching, or windows that stick, or visible separation at the brick outside, or floors that feel out of level — those together suggest movement beyond what drywall repair addresses.
We will tell you if we think that is what you have, and we would rather you get a foundation opinion first than have us cosmetically close a crack that is going to reopen in six months. That is not us turning down work. It is that a repair which reopens makes us look bad, and rightly.
Here is the thing homeowners do, and it is completely reasonable: you buy a tub of compound, you push it into the crack, you sand it, you paint. It looks perfect. And then somewhere between four months and a year later, there is a hairline right back where the old one was.
The reason is that the crack is a joint that is moving, and compound is not flexible. Filling it just puts brittle material into a gap that is going to open again. The compound cracks in exactly the same place because that is where the stress is.
The crack gets cut open into a V. This sounds backwards — making the damage bigger — but a hairline crack has no room for anything to bond in. Opening it gives the repair something to grab.
This is the step that matters and the step that gets skipped. Tape spans the crack and holds the two sides together as a unit. Without tape you have compound sitting in a moving gap. With it you have a bridged joint. Paper tape bedded in compound, or mesh with setting compound over it depending on the situation.
Multiple thin coats, feathered wide. A crack repair that is floated too narrow leaves a visible ridge running down the wall, which is arguably worse than the crack.
Then the texture gets matched across the repair so the line disappears.
Done this way, the repair holds through the seasonal cycle. We are not going to promise it is permanent forever — if your foundation moves enough, something will eventually give somewhere. But a taped and properly floated joint moves as a unit instead of splitting, and that is the difference between a repair that lasts years and one that lasts months.
Not all cracks mean the same thing, and the shape tells you most of it.
Running up and away from the top corner of a door or window. This is the classic, and it is stress concentrating around an opening as the house moves. Ordinary.
Dead straight, parallel to the joists. This is tape over a joint giving up rather than the house moving much at all. Very common in older homes and in ceilings that have been through a lot of attic heat.
Along the line of the header. Usually ordinary.
Not drywall at all — but if you see it, mention it, because combined with interior cracks it changes what we tell you.
We are drywall people, not engineers, and we will not read your slab. But the patterns are consistent enough to be worth knowing.
Ordinary is: hairlines, a quarter inch or less, in the predictable locations, not obviously getting worse. That is a house living on clay.
Worth a second opinion is several signs arriving together — cracks noticeably wider than a quarter inch, doors that stopped latching, windows sticking where they did not, visible separation in the brick, floors that feel out of level. Any one alone is usually nothing. Together they are a pattern.
If that is what we see, we say so before doing the work. We would rather lose the job than close a crack cosmetically and watch it reopen — a repair that fails is worse for us than a job we never took.
Same underlying cause, different symptom. A nail pop is the framing lumber moving with seasonal humidity and pushing the board outward along the fastener, popping a dome of compound off the head.
Which is why re-mudding the dome does not work — you have filled a symptom while the mechanism keeps running, and it pops again next season. The repair is to secure the board properly, deal with the fastener causing it, then finish and texture.
We do not do foundation work. We will tell you if we think you need it, and then get out of the way. We do not paint — we repair and texture. We do not remodel or frame.
The step that sounds backwards, so here is the logic.
A hairline crack is a gap with essentially no width. There is nowhere for tape to bed into and nowhere for compound to key into — anything you put on it is sitting on the surface rather than in the joint. That is why surface fills pop off so readily.
Cutting it open into a shallow V creates a channel with actual volume. Now the compound has somewhere to sit, the tape has a bedded foundation rather than a painted line to stick to, and the repair is anchored into the board instead of laid across it.
Making the damage bigger to make the repair smaller. It is genuinely how it works.
Cracks along a ceiling seam behave differently from wall cracks, and they are common in North Texas for a specific reason.
Your attic swings from cool to brutally hot across a single August day. The framing up there moves with that, considerably more than the framing in your conditioned walls does. Ceiling seams sit right at the boundary of that movement, and the tape over them either holds or it does not.
When it does not you get a crack running dead straight, parallel to the joists — which is how you tell it from a settlement crack at a glance.
Repairing it means the same discipline, but floated wider. Raking light across a ceiling finds any transition that happens too fast, so a ceiling crack repair that would pass on a wall will read as a ridge overhead.
Carrollton sits on the western side of our service area, a straightforward run from our Plano base.
It is also a city with a lot of established housing — neighborhoods that went up decades ago and have been riding North Texas clay ever since. That produces a very particular drywall profile, and by now we could probably guess what is wrong in a Carrollton home before we walk in.
That is where taping cracks comes in. And if you have other drywall damage in the same visit, tell us on the phone — multiple repairs done together are more efficient than one at a time, because the mud coats dry in parallel.

Tell us what happened and roughly how big the area is. A photo texted over usually settles the scope in a minute.
You get the scope and the number before we start. Patch versus sheet replacement, texture type, and how many coats it needs.
We cut, hang, tape, float, and match texture, then clean the space. Most single-room repairs are done inside one visit.

Our pricing starts at $300 for any job, however small. Beyond that it depends on the size of the damage, the texture that has to be matched, and how many coats the finish needs. Text a photo to (972) 469-5046 for a free virtual estimate and we will give you a real number, not a placeholder range.
Virtual estimates are free — text or email a photo and we will come back with a real number, no charge and no obligation. In-person estimates are $100, credited back against your job when you book with us. For most repairs a clear photo is all we need.
Most single-room repairs are handled in one visit. Larger areas, or repairs that need multiple mud coats to dry properly, can run into a second day. We tell you which one you are looking at up front.
Yes. Matching the surrounding texture is part of the repair, not an add-on. A flat patch with the wrong texture still reads as a repair.
Yes. Carrollton is inside our service area. Call (972) 469-5046 to get on the schedule.
A crack that is filled with compound will come back, almost certainly. A crack that is cut open, taped, and floated properly holds as a unit through normal seasonal movement. If your foundation is moving significantly, something may eventually crack again somewhere — but it will not just split back open along the old line the way a filled crack does.
Usually it is just normal seasonal soil movement, which is a fact of life on North Texas clay. It becomes worth a foundation opinion when you see several things at once: cracks wider than about a quarter inch, doors that stopped latching, windows sticking, separation in the brick outside. We will tell you if that is the picture we are seeing.
