Doors sticking and windows binding: the first sign of settling

A door that drags on its jamb is the first thing almost anyone notices, and it is the most reliable early symptom a manufactured home gives you. The fix, when it is settling, is a relevel at $450 to $800 for a singlewide or $750 to $1,400 for a doublewide, and the level check that confirms it is free.

What is actually happening

A manufactured home sits on piers. When those piers settle unevenly, the steel frame twists slightly, and everything built on that frame twists with it. Door and window openings stop being rectangles.

A door is built for a rectangle. Rack the opening by a small amount and the door catches at a corner, drags on the jamb, or will not latch. It does not take much: movement invisible to the eye is very visible to a door.

That is why doors go first, before cracks, before floors, and long before anything dramatic.

Check this first: settling, or just Florida humidity?

Worth separating, because one of these costs nothing.

Probably humidity if: one door only, it sticks through the summer and frees up in winter, the problem is at the top or the latch edge, and nothing else in the home has changed. Wooden doors and jambs swell in a Sumter County August. A strike plate moved a sixteenth of an inch often settles it permanently.

Probably settling if: more than one door does it, it does not reverse with the season, it is getting worse year on year, a door swings open or closed on its own when left halfway, windows have started binding too, or cracks are opening at wall and ceiling joints, especially over doorways.

Almost certainly settling if: on a doublewide, the marriage line, the seam down the center of the ceiling or floor, has started to gap. That one is close to conclusive, because it means the two halves are no longer sitting at the same height.

The two-minute confirmation

The marble test. Set a marble on the floor in three different rooms. If it rolls the same direction every time, the frame is low on that side. If one room goes its own way, that is a local problem, usually a lost pier or a soft subfloor.

The door swing test. Open every interior door halfway and let go. Doors that drift open or closed on their own are telling you the frame has racked.

Then run the settling self-check, which scores twelve visible signs and will tell you honestly if your home does not need anything yet.

Cause, fix, and cost

Why homes settle around Wildwood

Sumter County is a blanket of sand over the Ocala Limestone, and the soil survey maps the ground under Wildwood and Oxford in loose sands, Candler, Arredondo, Kendrick, and Tavares, that drain fast and hold a point load badly. Sand under a concentrated pier load migrates and compacts, faster once it has been wet, and the Lisbon climate station normals put 55 percent of the year’s 50 inches of rain into June through September.

The cause and the symptom are months apart, which is the part people find odd. A wet August produces sticking doors the following February, and the owner blames that week’s weather rather than the previous summer’s.

Three to five years is an honest maintenance interval for most homes here, at the short end if the ground stays wet. Releveling on sandy soil is maintenance rather than a repair you do once, and anyone claiming otherwise is selling something.

What the work involves

The home is measured pier by pier so the readings tell you where it actually sits, not where it looks like it sits. Then it is brought back to level: piers reset or rebuilt where needed, shims adjusted, pads replaced where they have pressed into the ground. The skirting comes off for access and goes back afterward.

Doors and windows usually free themselves once the openings are square again. Where a door has been forced or a jamb damaged while it was binding, it may need adjusting afterward, and we will say so before the work rather than after.

While somebody is under there

Two things worth doing on the same visit, because the skirting is off and the crew is underneath:

Anchoring. Straps slacken as a home settles, so a home that needs leveling usually has tie-downs that have lost tension. Re-tensioning is included with the relevel. See loose or rusted tie-downs.

The underbelly. Tears let water and animals at the insulation, the ductwork, and the subfloor. Patching runs $300 to $800 and it is far cheaper done while everything is open.

When to call

When more than one door does it, when it does not reverse with the season, or when the marble rolls. Tell us how many doors are affected, whether it reverses with the season, what the marble test showed, whether the marriage line has gapped on a doublewide, and roughly when the home was last leveled. The level check is free and takes about half an hour, and the cost calculator gives you a range now.
