910 Crawl Space Pros provides crawl space door replacement across Wilmington and the Cape Fear region. Crawl space door replacement fits an insulated, gasketed and lockable access door in a proper frame. It is a small item that carries a disproportionate share of the air and water leakage in an otherwise sealed crawl space.
What we do on the first visit
Measure the existing opening, check whether the frame itself is sound, and look at how water behaves at that point — many access doors sit at a low spot where runoff collects.
The weakest point in most sealed crawl spaces
A crawl space can be lined, sealed and conditioned to a high standard and still lose its humidity target through a plywood hatch held on with two screws. The access door is a hole in the envelope, and unless it is detailed as such it stays one.
It is also usually the lowest point in the perimeter wall, which makes it the place surface water enters first. A door set flush to grade in a Wilmington yard will take water every heavy storm.
What a proper door actually has
An insulated panel rather than bare plywood, a continuous gasket that compresses when latched, a frame set into the opening rather than screwed over it, and a latch that holds the compression. Lockable matters too — an open crawl space invites animals.
Where the opening sits low, a well and a threshold above grade level keep surface water from simply running in. That detail is more important on this coast than the door itself.
What's included
- Measurement and assessment of the existing frame
- Insulated access door with a continuous compression gasket
- Frame set into the opening and sealed to the wall
- Latch that holds gasket compression, with a lock
- Threshold detail above grade where the opening sits low
- Well and drainage where surface water collects at the opening
- Sealing to the vapor barrier termination where present
- Demonstration that the door closes and seals properly
