Signs of Foundation Problems in Plano — and How to Prevent Them
Learning to read your house helps you tell routine settling from the signs that merit an inspection, and a few seasonal habits make movement smaller.
01 — What this covers
The work itself
- Stair-step cracks in brick and veneer
- Diagonal cracks at doors and windows
- Doors and windows that stick or won't latch
- Floors that slope or bounce
- Gaps at crown molding, baseboards and ceilings
- Wide or offset slab cracks
- Watering, drainage and tree habits
02 — Detail
Inside the house
Check doors first. A door that rubs at the top, won't latch or swings open indicates that its frame is out of square. Then look at windows: any that suddenly stick, or whose caulk has split, may be responding to movement.
Look up and down. Gaps between crown molding and ceiling, cracks where walls meet ceilings and tile that cracks in a straight line all point to flexing. A floor that slopes — try placing a ball on it — or that feels springy suggests lost support below.
03 — Detail
Outside the house
Brick and stone are good witnesses. Stair-step cracks in mortar joints, a gap between the veneer and a window frame or a lintel that has sagged are signs of movement. Also examine the trim under the eaves; separations there can follow wall shifts.
On the slab edge, hairline cracks are common. Wide cracks, or those with one side higher, are not. In summer, notice any gap between soil and slab, which indicates shrinking clay.

What's normal
Drywall seam cracks, small cracks in garage floors along control joints and a door that sticks briefly in a humid week all occur in healthy houses. A single small crack that isn't changing rarely means a problem.
Pay attention to patterns and trends. Mark the end of a crack with a pencil and the date; if it's longer a few months later, it's active.

Seasonal habits
Keep moisture even. During dry spells, run a soaker hose a foot or two from the slab, but avoid saturating the soil. In wet seasons, clean gutters, extend downspouts and keep the soil sloping away.
Manage trees and irrigation. Keep new trees away from the house, consider root barriers for large ones and make sure sprinklers don't soak one wall while another stays dry.

When to book an inspection
Book one when several signs appear together, when cracks are growing, before buying a home with noted movement, after a plumbing leak under the slab and a year or two after a repair. It's free from a local repair company and useful even when the answer is “this is normal.”

A simple annual walkthrough
Once a year, in late summer when the soil is driest, walk through the house and around it with a notebook. Record any new cracks, the doors that stick, any gaps at trim and the condition of the slab edge. Take photographs and note the date. Compare with last year's notes.
That record is the best tool you can give an inspector, and it makes the difference between guessing and knowing whether something has changed.

What it costs
Maintenance costs a fraction of a repair: gutters, extensions, grading and a soaker hose are inexpensive compared with a single pier.
Questions
Signs of Foundation Problems & Maintenance Tips — asked and answered
Does a crack in brick always mean foundation trouble?
No. Brick cracks with temperature and age too. Stair-step cracks near corners that keep growing deserve a look.
How far from the slab should a soaker hose be?
About a foot or two, used during dry spells.
Is a sticking door always a foundation problem?
No. Humidity can swell doors. Multiple sticking doors with cracks above are more telling.
Can movement reverse by itself?
Seasonal movement partly reverses as moisture returns. Ongoing settlement doesn't, but drainage can slow it.
