Crawl Space Repair in Tulsa, OK

Dry, sealed, structurally supported. We fix what's wrong under your house.

Most Tulsa homeowners don't think about the crawl space until something goes wrong. Then they crawl down there with a flashlight and find standing water, fiberglass insulation falling off the joists, mold on the floor framing, and a musty smell coming up through the floors. That's a fixable problem and the fix is worth the money.

What we do

Encapsulation. A heavy duty vapor barrier across the floor and up the walls. Seals out ground moisture and humidity. Stops mold growth.
Dehumidifier installation. Crawl space rated dehumidifier ties into the encapsulation. Keeps relative humidity below 55 percent year round.
Sump pump and drainage. Interior perimeter drain and sump pump to handle water that gets in.
Joist and beam repair. Replace rotted joists, sister sagging ones, install new pier supports where needed.
Pier installation. Adjustable steel piers under sagging floors. Lift, support, and level.
Insulation removal and replacement. Out with the fallen fiberglass, in with closed cell foam where appropriate.

Why Tulsa crawl spaces fail

Three reasons usually. First, our humidity. Eastern Oklahoma summers run hot and wet. That moisture finds its way into the crawl space and never leaves. Second, our soil. Clay shrinks and swells, which moves the perimeter and lets ground moisture in. Third, age. Many midtown homes were built before vapor barriers were standard.

What it costs

Full encapsulation on a 1,500 square foot crawl space: $7,500 to $14,000
Encapsulation plus dehumidifier: add $1,800 to $3,200
Sump pump install with interior drain: $2,200 to $4,500
Pier support for sagging floors: $600 to $1,200 per pier installed

25 year warranty on encapsulation work. The vapor barrier itself is rated for that long and we stand behind it.

FAQs

Why does my crawl space smell musty?

Moisture and mold. Tulsa humidity gets trapped under the house and feeds mold growth. Encapsulation stops it.

Will crawl space encapsulation lower my power bill?

Usually yes. A sealed crawl space is one less place your HVAC fights humidity. Most customers see 5 to 15 percent lower summer bills.

Do I need a sump pump in my crawl space?

Only if water collects there. We measure the slope of the dirt and the path of any drainage. If water has nowhere to go, we add a pump.
