Doors and Windows That Stick or Won't Latch

A door that used to latch and now sticks, or a window that takes two hands to open, is usually not a door problem. It is the frame going out of square because the house underneath it moved. Here is what causes it, how to tell foundation movement from ordinary humidity, and how we fix the cause instead of planing the door. 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

What a racking door frame looks like

Wood moves a little with the seasons and that is normal. These are the signs that say something structural is behind it instead.

A gap that tapers around the door
Close the door and look at the gap all the way around. Even gap, square frame. Wide at one corner and tight at the opposite one means the frame has racked.
A crack angling off the frame corner
A crack running diagonally up from the top corner of a door or window is the wall telling you the opening is being pulled out of square.
A latch you have to lift to catch
When you find yourself lifting or leaning on the door to line the bolt up with the strike plate, something moved the strike plate.
Windows that won't stay open
Sashes that slide shut on their own, or take real force to move, often mean the opening is no longer square.
It gets worse every year
Some seasonal swing is normal wood movement. A door that never comes back, or gets a little worse each year, is not seasonal.

The diagnosis

What's pulling your frames out of square

A quarter inch of movement in the structure is more than enough to stop a door from latching. Here are the three things that usually put it there.

Foundation settlement

When one part of the footing drops, the wall above it tips slightly out of plumb and the door frame goes with it. You do not need dramatic movement for a door to stop working.

A failing support system underneath

In a crawl space home, settled posts or a split girder let the floor sag in the middle. The wall sitting on that floor drops with it and racks the frames upstairs.

Moisture swelling the framing

Humidity coming up out of the crawl space swells joists, subfloor, and jambs. This one can be seasonal and reversible, which is exactly why we look underneath before recommending structural work.

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

How serious is it

Doors are usually the first thing you notice

That is good news. Noticing early is what keeps this from becoming a list of repairs instead of one.

Caught early

Fix the cause, the doors follow

Correct the settlement or the failing supports now and the frames come back toward square, before the drywall and the brick outside start telling the same story. This is the cheapest and least disruptive point on the whole timeline.

Left alone

It spreads to everything attached to the frame

Movement that keeps going cracks drywall and trim, separates the brick outside, and eventually damages the doors and windows themselves. Replacing a door in a frame that is still moving buys you a season at most.

The prescription

How we get your frames back to square

The fix depends on where the movement is coming from, and that is a question we answer before we quote anything. These are the methods we actually perform.

Pier Stabilization

Steel piers carry the settled section down to soil that will hold it and lock it there, so the wall above stops tipping and the frame stops racking.

Best for: Homes where the frames are racking because the foundation has settled.

Crawl Space Support Repair

New posts, beams, and proper footings under the joists take the sag out of the floor system, so the walls standing on it stop dropping.

Best for: Crawl space homes where the movement comes from underneath, not from the footing.

When it's just the door

Sometimes the house is fine and the door needs a plane and a new strike plate. We will tell you when that is the case. We are not going to sell you a foundation job to fix a forty dollar problem.

Best for: Seasonal sticking with no measurable movement in the structure.

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

Sticking doors rarely travel alone

The movement that racks a door frame usually shows up somewhere else too. If you are seeing these, they point to the same diagnosis.

Stair-step cracks in brick

Diagonal cracks stepping up the mortar outside usually track the same movement racking your frames inside.

Cracks in drywall or trim

A crack off the corner of a door frame is the drywall version of the exact same problem.
Diagnose the cause

Sagging or bouncy floors

If the floor under the wall is dropping, the frames standing on top of it go out of square with it.
What's underneath

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

Sticking door questions

Straight answers about doors that won't close

Because the frame is no longer square. When the house settles or the floor under it drops, the frame racks and the bolt stops lining up with the strike plate. A quarter inch of movement is enough. Wood swelling in humid weather can do it too, which is why we check underneath before calling it structural.
