At iFixBasements, crawl space repair in Rockland, Orange, Bergen and Essex counties means finding out what actually broke down there — standing water, a failed vapor barrier, falling insulation, sagging supports — and fixing it in the right order, with the water first.
I personally inspect and design the fix; a licensed & insured certified dealer crew installs it. The estimate is free, you get a written proposal the same day, and no-money-down financing is available through the installing dealer’s lenders.
If you’ve never been down in your crawl space, I get it — nobody wants to. I’ll go down there for you and tell you what I see.
What breaks in a crawl space
- Standing water or a wet dirt floor. The crawl space takes on water after heavy rain.
- A failed vapor barrier. Thin plastic that’s torn, bunched up or never sealed to the walls.
- Falling insulation. Fiberglass batts that got damp and are hanging out of the joist bays.
- Sagging supports. Joists or girders that are bowing, or posts that have shifted.
- Open vents. Humid outside air gets in and condenses on cooler surfaces.
Wet crawl space — water comes first
A wet crawl space has to be dealt with before anything gets sealed. Covering an active water problem just traps it. I look at where the water is coming from — the walls, the floor, a downspout outside — then design drainage to carry it out, with a sump pump when needed.
What I check
I get in the crawl space myself. I check the floor and walls for water and staining, the vapor barrier, the vents, the insulation, the joists and supports for sagging or damage, and the grade and gutters outside.
Crawl space waterproofing — the fix sequence
- Drainage first. Drainage matting and, where needed, a sump system.
- Heavy-duty vapor barrier. Sealed to the floor, walls and piers.
- Sealed vents. So humid air stops getting in.
- Rigid foam insulation. On the walls, in place of sagging fiberglass.
- Dehumidifier. To keep humidity down year-round.
- Support where it’s needed. If I find sagging framing, adjustable steel supports go into the plan.
You may not need every step. I ask what you want fixed and price everything together. Anything you’d rather handle yourself comes off the list. No hard sell.

Crawl space repair questions
Can I just patch the vapor barrier myself?
Thin plastic slows moisture for a while, but it tears and doesn’t seal at the seams or walls. A real fix is a heavy-duty liner sealed to the walls and piers, with drainage and a dehumidifier.
How do I know if the crawl space is why my floors are cold or my house smells?
Warm air rises and pulls air from the lowest part of the house in — including the crawl space. If the air down there is damp, you notice it upstairs. I check it directly.
What if my crawl space has standing water?
That gets fixed first. I find where it’s coming from and design drainage before anything gets sealed.
How much does crawl space repair cost?
Honestly, I can’t give you a number without seeing the space. It depends on the size, access, water and what needs replacing. The estimate is free.
