Sticking doors and windows can be signs of soil movement under the foundation. Ask a repair company to assess them when they appear alongside frame gaps or cracks above openings.

Swollen wood or a shifting frame

The Colorado Geological Survey describes both causes in one place. Doors and windows that stop closing properly are distorted. Heave from swelling soil can do that. So can green wood, meaning lumber that was not fully dried.

Tell the repair company when the sticking began and whether it changes with the seasons. Ask it to check both the door or window and the surrounding frame.

ASCE’s homeowner guide lists sticking doors, sticking windows and cracks above doors and windows as signs of soil movement. It names gaps between frames and walls as an outside sign. It also says the more of these you see, and the more often, the more likely it is that the foundation has shifted.

What to check today

Use your phone camera to record what you find.

  • The gap. Close the door and look at the gap around it. Is it even all the way around, or shaped like a wedge?
  • The latch. Does the latch meet the strike plate, or hit above or below it? Mark where it hits.
  • The hinges. Look for loose screws and tell the company whether tightening them changes how the door closes.
  • The wall above. Look for cracks running up from the top corners of the frame.
  • Outside. Check the frame from outside. Look for gaps where it meets the brick or siding.
  • The ground nearby. Look for water that collects near that wall. The Foundation Performance Association warns that air-conditioner water dumped next to the house can cause uneven movement in one spot.

Write down which doors and windows stick, and the date. Check them again in a month and after the weather changes. A list like this helps the company see what is moving.

How Oklahoma clay moves a door frame

ASCE’s homeowner guide says changes in soil moisture push a foundation up and down. Drought can let part of a house drop. Too much water, from a leak or a sprinkler, can push part of it up. When one corner moves more than the rest, door and window openings lose their square shape.

In Creek County, 37.4% of mapped acres have high or very high shrink-swell soil, by USDA survey estimates. In Pottawatomie County the share is 20.9%. These are county-wide figures, not a test of your lot. Still, they are a good reason to choose a company that works on this clay all the time. The Sapulpa and Shawnee pages cover the local permit steps.

When it points to the foundation

Have a repair company assess the house in these cases:

  • several doors or windows started sticking around the same time;
  • a door that used to latch now will not;
  • new cracks appear above doors or at frame corners;
  • the floor near the sticking door feels like it slopes.

The sloping floors page explains how to check a floor. The foundation cracks page shows how to track a crack. For all signs sorted by urgency, see foundation warning signs.

If a sticking door comes with a gas smell, leave the house first. Once you are outside, call the gas company and emergency services.

Repair company first, engineer if needed

Start by scheduling a repair company to look at the sticking openings and nearby damage. Ask for its findings about the movement, the likely cause and any recommended repair. An independent structural engineer makes sense when the cause is unclear, when bids disagree, or when a lender or buyer wants a report. The foundation repair cost page shows what common repairs cost.

Asking for a quote

Send the quote form with the list of doors and windows that stick and when it started. Request an on-site look and an itemized repair price from a local company. Ask for the quote to cover:

  • whether the foundation has moved, and where;
  • the repair it proposes, if any;
  • drainage or water work near the house;
  • whether the job needs a permit and the company will handle it, with the fee listed.
