Insulation between the floor joists soaks up damp, sags, and falls
In a vented crawl space, the insulation usually sits in the floor: fiberglass batts pushed up between the joists, with open vents in the foundation walls below them.
Summer air near Fairfield Bay is heavy with water. Hourly readings at Clinton's airport, about 9 miles west, put the average July dew point at 71.4°F from 2015 to 2024. The U.S. Department of Energy's Building America program found that air coming in through crawl space vents is more likely to condense on the framing than to dry it.
Fiberglass batts hold that moisture against the subfloor. They get heavy, droop, and drop onto the dirt, and the wet paper facing can grow mold.
Winter finds the gap the fallen batts leave. NOAA's 1991 to 2020 normals put January's mean temperature at 38.1°F at Greers Ferry Dam, and that air blows through the vents under a floor with nothing left above it.
Quick answers about crawl space insulation
Something not here? Call and ask Christian.
(501) 550-1115Will insulating the crawl space walls make my floors warmer?
It can. Insulated foundation walls and rim joists keep winter cold from reaching the space under your floor once the vents are sealed. That Crawl Space Encapsulation Guy checks the walls, the rim joists, and the vents at the $100 inspection.
How long does crawl space insulation take?
Half a day to a day and a half for the walls and rim joists. That Crawl Space Encapsulation Guy needs longer when old insulation has to come out first, and your written price says when that applies.
Will you add work I don't need?
No. Every line on That Crawl Space Encapsulation Guy's written price comes with a reason, so you see why each piece of work is there before you agree to it. The price arrives within 24 hours of the inspection.
Insulated walls and rim joists keep a sealed crawl space warm
Crawl space wall insulation moves the insulation out of the floor and onto the foundation walls and the rim joist. The crawl space, with the ducts and pipes in it, ends up on the warm side of the insulation.
Wall insulation belongs in a sealed crawl space, where the vents are closed and a liner covers the ground. The 2021 International Energy Conservation Code lets crawl space walls go uninsulated only where the crawl is vented and the floor above it is insulated.
Christian looks at your walls, your rim joists, and any old batts at the inspection. What he'll install, and why, goes on your written price line by line.
How a crawl space insulation job goes
- The $100 inspectionChristian goes under the house and checks for water, rotted wood, open vents, and the insulation already there.
- A written price within 24 hoursEach line has its reason, including any water or wood work that has to be done before the insulation.
- Water and wood firstChristian works in one order: water first, wood second, air last. Insulation is part of the air work, so it goes in after leaks, drainage, and rot are handled.
- Walls and rim joists insulatedThe foundation walls and rim joists get insulated. If rot, water, or mold turns up once the work starts, Christian stops and gives you a written price for it before doing more.
- Work done, and Christian a call awayHis phone rings around the clock, and if he damages a duct, drain line, or sprinkler line while working, he pays to fix it.
Crawl space insulation costs $800 to $2,500 for most crawl spaces
That range covers insulating the foundation walls and rim joists. Work that has to come first, like drainage or sealing the crawl space, is priced on its own line.
When you hire That Crawl Space Encapsulation Guy for the insulation, the whole $100 inspection is credited to the job. The deposit pays for the materials, and the rest is due in stages as the work gets done.
Insulation won't dry out a wet crawl space
Insulation does nothing to stop water. Put over a damp wall or under a wet floor, it holds the moisture against the wood and hides the problem. Standing water, a plumbing leak, or rain running under the house has to be stopped first. Drainage runs $1,200 to $3,500, and a vapor barrier over the dirt floor runs $1,500 to $4,000.
That Crawl Space Encapsulation Guy doesn't do pest control or radon mitigation.
Work that often goes with this
Will crawl space insulation lower my heating and cooling bill?
It can. In a field study funded by the U.S. Department of Energy, homes with closed crawl spaces saved 15% or more on heating and cooling. That Crawl Space Encapsulation Guy insulates the walls and rim joists that keep a closed crawl space warm in winter.
What R-value do crawl space walls need?
In climate zone 4, the 2021 International Energy Conservation Code calls for R-10 continuous or R-13 cavity insulation on crawl space walls. R-value measures how well insulation slows heat. That Crawl Space Encapsulation Guy lists what goes on your walls on the written price.
What happens to the old insulation that fell on the ground?
It comes out before anything new goes in, and the job takes longer. Clearing old insulation and debris is crawl space cleanout work, which That Crawl Space Encapsulation Guy prices at $500 to $2,500.
Is it better to encapsulate or insulate my crawl space?
Wall insulation goes with encapsulation, after the vents are sealed and the liner is down. That Crawl Space Encapsulation Guy prices encapsulation at $5,000 to $10,000, and the inspection shows whether your crawl space needs it.
