Why are my floors cold, and will insulating the crawl space help?

Crawl space insulation in Santa Maria either fills the floor framing above the crawl space or lines the crawl space walls, so the rooms over it stop losing heat through the floor. A floor sitting over that unheated space under the house can be one of the main places a home loses heat, and it's usually why floors feel cold through your socks.

Most people call us about a room that never warms up or a floor that's cold every winter morning, and the crawl space is often where it starts. The price turns mostly on how many square feet the crawl space covers, which method fits, and what's down there that has to be handled first, like old insulation that's fallen or ruined and needs insulation removal, or old pipe wrap that has to be checked. The schedule turns on those same things and on whether the building office wants a permit. I write your figure after I've been under the house, because that's the only place the real answer is.

How we handle crawl space insulation

The first question on every crawl space is whether we insulate the floor above it or close it up and insulate its walls, and I'll walk you through which one fits your house. Anything down there that changes what's safe, like a furnace, a water heater or old wrap on the pipes, gets planned for before our crew starts, so nobody finds it halfway through. Then we seal the holes where pipes and wires pass through the subfloor, because insulation over an open gap just lets the draft through. After that the insulation goes in, fitted so the edges get as much coverage as the middle, and we clean up on the way out. Satisfaction guaranteed on every job.

Cold floors are often only part of what you're feeling. If rooms still feel drafty after the floor is done, air sealing services close the gaps elsewhere in the house, and if the outside walls feel cold to the touch, wall insulation is the next place to look. I'll tell you if I see either one while I'm there, and just as plainly if I don't.

Crawl space insulation in Santa Maria and what we plan for

The City of Santa Maria Building Division checks that construction work in the city has the permits it needs, and I don't assume either way whether your crawl space job needs one. Before work starts we check with the building office that covers your address, city or county, and if they say a permit is needed, we take care of the application and set up the inspections. If you'd like to ask them yourself, the city's permit staff take questions by phone at (805) 925-0951 x2241 during normal business hours.

We're based in Santa Maria and work across the cities around it in northern Santa Barbara County and southern San Luis Obispo County, and a lot of what we crawl under is older raised-floor houses with open vents, ducts running underneath and nothing touched in years. We see the same setup on jobs in Orcutt and Nipomo, so we go in expecting old wraps and equipment and plan for them.

Frequently asked questions

What is the best way to insulate a crawl space, the floor or the walls?

Sealing and insulating the crawl space walls is generally considered best practice in every climate, though in some homes the floor above works better as the insulated line. Insulating the walls brings the crawl space inside the house and insulating the floor leaves it outside, so where ducts or a furnace sit down there I usually lean toward the walls, once that equipment has been planned for.

What happens if I just close my crawl space vents?

Closing the vents by themselves can raise the moisture in the crawl space, so turning a vented crawl space into a sealed, insulated one takes more than blocking the openings. If there's a furnace or water heater down there that draws its air naturally, sealing the space without planning for it could be deadly, so that gets sorted out first.

How much does crawl space insulation cost in Santa Maria?

Across the US, insulating a crawl space usually costs about $3 to $6 per square foot. That's what the work tends to run nationally, not our price, and where your job lands depends on the size, the method and anything that has to be handled first. I give you your own figure after I've been under the house.

Who is allowed to insulate a crawl space in California?

California's Contractors State License Board treats installing any insulation for heat or sound control as licensed insulation contracting. Someone without a license can take on minor work up to $1,000, but only if the job doesn't need a permit and they don't hire anyone to help.

How do I deal with old pipe wrap in my crawl space before insulating?

Leave it alone and have a certified asbestos abatement firm inspect it before any insulation work starts. Older crawl spaces sometimes have asbestos-based wrap on ducts and plumbing pipes, so if I see suspect wrap at the estimate, I'll tell you and we plan the time and budget for that step first.

What should I ask a contractor before they insulate my crawl space?

Ask how they'll keep the batts, the insulation blankets that go between the floor joists, tight in place with no gaps, squashed spots or voids. If foam is going on the crawl space walls, ask whether it meets the fire safety rules of your local code office.

  • Wall insulation

    Worth a look if your floors are warmer now but the outside walls still feel cold on a winter night.

  • Air sealing services

    Closes the cracks and openings around the rest of the house so warm air stays where you're living.
