Test It Before You Blame Humidity
Sticking Doors
and Windows
in Maryland
Every homeowner has a door that sticks a little in August humidity. A door that sticks year round is telling you something different.
Seasonal wood swelling eases once the air dries out. A frame racked out of square by foundation settlement binds at a consistent point regardless of season. OBW tests which one you're dealing with before recommending a fix.
Two Different Causes, Two Different Fixes
Why a Door or Window
Starts Binding
Seasonal humidity swells wood, so a door or window sash that binds during Maryland's humid summer months and loosens up once the air dries out is usually just responding to moisture, not the foundation. A door frame that's racked out of square is a different problem. When the foundation beneath one part of a wall settles, the wall shifts slightly out of plumb, and the rectangular door or window frame set into it is no longer perfectly rectangular.
The door binds against the frame at a consistent point, in the same season or out of it, because the frame itself has changed shape. That constant, season-independent binding is the tell. It's often noticed once a frame already showing a slightly uneven reveal has racked far enough that the door or sash begins catching against it, not just showing a visible gap.
Foundation movement racking a wall out of plumb, the structural cause behind constant, season-independent sticking
Telling the Two Apart
Warning Signs Your Sticking Door
Is a Structural Issue
If the cause is structural, foundation leveling addresses the settlement driving the frame out of square rather than just planing the door.
- Sticking that doesn't ease when the weather dries out in fall or winter
- More than one door or window on the same side of the house sticking at once
- Binding at a consistent point on the frame every time, not a variable drag
- An already-noticed uneven reveal at the same frame before the sticking started
- Visible cracks in nearby foundation walls or basement block
What's Included
OBW's Sticking Door & Window
Diagnosis
We test for the cause before recommending anything, since humidity and settlement need completely different fixes.
Humidity vs. Structural Test
We check whether sticking tracks with seasonal humidity or stays constant regardless of weather, the key diagnostic split.
Frame Square Measurement
The frame is measured for square and checked for which direction it's racked, if the cause is structural.
House-Wide Frame Check
Other doors and windows are checked for the same binding pattern, since multiple frames sticking at once points to settlement.
Foundation Settlement Diagnosis
Where structural, the racking pattern is traced to the specific foundation section responsible.
Foundation Leveling
Structural repair addresses the settlement racking the frame, rather than planing the door to mask it.
Written Workmanship Guarantee
Structural repair work is backed by a written workmanship guarantee. Ask your inspector for the terms that apply to your job.
The Process
How OBW Diagnoses Sticking
Doors and Windows
Test the seasonal pattern. Measure the frame. Check the house for other binding frames before recommending a fix.
Seasonal Pattern Check
OBW asks when the sticking started and whether it eases with drier weather, the first split between humidity and structure.
Frame Square Measurement
The frame is measured for square, and the direction of any racking is documented.
House-Wide Binding Check
Other doors and windows are checked for the same constant, season-independent binding.
Leveling Plan & Written Quote
Where structural, a written quote specifying the settlement location and repair scope, before any work is scheduled.

Straight Answers
Sticking Door & Window Questions
from Maryland Homeowners
Call (410) 879-3360 if a door or window has been sticking longer than a season. Our inspectors will tell you which cause it is.
How do I tell if my door is sticking from humidity or from my foundation?
The clearest test is whether the sticking eases when the weather dries out. Seasonal humidity swells wood, so a door or window sash that binds during Maryland's humid summer months and loosens up once the air dries out in fall is usually just responding to moisture, not the foundation. That's normal wood movement, and it's not a structural concern.
A door frame that's racked out of square is a different problem. When the foundation beneath one part of a wall settles, the wall shifts slightly out of plumb, and the rectangular door or window frame set into it is no longer perfectly rectangular. The door binds against the frame at a consistent point, in the same season or out of it, because the frame itself has changed shape.
What if more than one door or window is sticking?
That's a meaningful signal. If sticking doesn't ease when the weather dries out, or if more than one door or window on the same side of the house has started sticking around the same time, that pattern points to foundation settlement rather than humidity. OBW's free inspection checks the frame for square, looks at which direction it's out of alignment, and connects that reading to what's happening at the foundation below.
Does sticking usually show up before or after other frame problems?
It's often noticed once a frame that's already showing a slightly uneven reveal has racked far enough that the door or sash begins to bind against it, rather than just showing a visible gap. If sticking continues unaddressed, it can progress toward a door that eventually stops latching altogether, as the underlying movement continues.
Can I just plane the door down so it swings free again?
You can, and it will work temporarily if the cause is structural, but planing only removes material to compensate for the current frame shape. It doesn't stop the frame from continuing to move if the settlement causing it isn't addressed. Foundation leveling addresses the settlement driving the frame out of square rather than just planing down the door to make it swing free again, a fix that only masks the symptom.
What does OBW actually check when a door or window is sticking?
We check the frame for square, measure which direction it's out of alignment, and test whether the sticking tracks with humidity or stays constant regardless of season. That reading, combined with a check of other doors and windows in the house, tells us whether we're looking at normal wood movement or foundation settlement. Backed by a written workmanship guarantee, terms vary by service, ask your inspector.
