Cracks in Your Drywall or Trim

A drywall crack you patch every couple of years is not a drywall problem. It is the house moving, and drywall is simply the first thing that gives. Here is what is moving, how to tell a settling crack from ordinary drying, and how we stop the movement so the patch finally holds. We diagnose the real cause first, then prescribe the fix that matches it, not the priciest one. Free in-home inspection, no pressure.

What you're seeing

Which cracks are worth paying attention to

Every house has a few hairlines. These are the patterns that mean something is still moving behind the wall.

Cracks angling off door and window corners
The corner of an opening is where a wall is weakest. A crack running diagonally away from it is the classic movement crack.
Seams that keep reopening
Tape joints that split again within a year mean the wall is still moving. New mud on a moving wall is a temporary fix by definition.
Trim separating at the miters
Crown and baseboard joints that open up show the wall or the ceiling has shifted since the trim went on.
A line opening where ceiling meets wall
A gap running along the ceiling seam usually means the floor or the wall below it has dropped.
Nail pops across a whole wall
Rows of popped fasteners mean the framing has moved relative to the drywall attached to it.

The diagnosis

What's moving behind the wall

Drywall is rigid and thin, so it cracks before anything else does. The useful question is what moved, and telling that apart from normal drying is most of the job.

Foundation settlement

When part of the foundation drops, everything framed on top of it goes slightly out of square. The drywall cracks first, and it cracks in the same predictable places every time.

A floor system that's sagging

In crawl space homes, a settling girder line lets the floor drop in the middle. The walls standing on that floor drop with it and the seams split.

Normal drying and settling

New construction shrinks as the framing dries out, and that causes hairline cracks that never come back after one patch. Separating that from real movement is exactly what the inspection is for.

Not sure which one you have? That's exactly why we diagnose first.

How serious is it

The crack is cheap. The movement isn't.

Drywall is the least expensive thing in your house to repair, which makes it the least expensive place to catch a problem.

Caught early

Patch it once and be done

Find out now whether the cracks trace to movement. Correct the cause, let it settle, and the patch you do afterward is the last one you will pay for on that wall.

Left alone

You keep buying the same repair

Movement that continues works its way outward. Doors stop latching, brick starts stair-stepping outside, floors begin to slope. Meanwhile you are re-mudding the same seam every couple of years and paying for it every time.

The prescription

How we stop the movement behind the crack

There are two structural causes worth fixing and one that does not need fixing at all. We measure before we tell you which one you have.

Pier Stabilization

Where the cause is a settled footing, steel piers carry that section down to soil that will hold it. The movement stops, and so does the cracking above it.

Best for: Homes with settlement showing up in more than one place.

Crawl Space Support Repair

Where the cause is a sagging floor system, new posts, beams, and footings under the girder line take the movement out from underneath the wall.

Best for: Crawl space homes with cracks appearing over a dipping floor.

When the house is done moving

Some cracks are old news from framing that dried out years ago. If we measure and find nothing active, we will tell you to patch it once and forget it.

Best for: Hairline cracks with no measurable movement behind them.

The FoundationRX Diagnostic Method

We diagnose. We prescribe. We treat.

A lot of foundation repair companies show up to sell you the most expensive thing they install. We show up to figure out what's actually wrong under your home first, then prescribe the repair that fixes it, and tell you straight, even when the answer is "you don't need as much as you were told." That's the difference between a sales call and a diagnosis.

01

Diagnose

A free in-home inspection by someone who does this work, not a commission salesperson. We look at the real signs, inside and underneath, and walk you through what's actually causing the movement. You get a clear, honest read on where your home stands.

02

Prescribe

We lay out the right fix for what's actually wrong, not the priciest line item. A plain-English explanation, a fair price in writing, and the warranty terms with it. We go over the plan and your options, and you decide on your own time. No "today only" pressure.

03

Treat

Dependable work by our own local crew, on time, cleaned up after themselves, and finished on or ahead of schedule, the way our customers describe it. We keep you in the loop the whole way, and we stand behind the work for the life of the structure.

Most foundation companies sell you a fix. We diagnose first, then prescribe only what your home actually needs. That's the difference between an honest local team and a sales quota from out of town.

Related warning signs

Drywall cracks rarely travel alone

Interior cracking is usually one symptom of something showing up in two or three places at once. These are the ones to check next.

Sticking doors & windows

Cracks at the frame corners and a door that won't latch are the same movement telling one story.
Why this happens

Stair-step cracks in brick

The outside version of the same problem. Check the brick where your inside cracks line up.
See if yours is serious

Sagging or bouncy floors

If the floor is dipping, the walls standing on it drop too, and the drywall is what splits.
What's underneath

Not sure which one you have? That's exactly why we diagnose first.

Drywall crack questions

Straight answers about cracks that keep coming back

Sometimes. Hairline cracks from a house drying out are normal and stay put after one patch. Cracks that reopen, run diagonally off door and window corners, or show up alongside sticking doors and brick cracks outside point to movement.
