Cold floors in the rooms above
When a kitchen or back bedroom floor stays cold all winter, the crawl space under it is usually open to outside air, with insulation that's thin, missing or fallen off the joists.

What crawl space insulation does for your house
Crawl space insulation in Altoona keeps the rooms above warmer by insulating the walls of a closed crawl space or the underside of the floor over a vented one, and it helps keep the pipes and heating equipment down there from freezing.
In an older house, the rooms over a crawl space are often the coldest ones, and what's underneath has usually been patched a few times over the years. The price turns on the size of the space, how easy it is to crawl around in, whether we seal it or insulate under the floor, and how much old material needs insulation removal first, and the schedule turns on that same work plus any permit the job needs. I'll get under your house and give you a price for it when I come out to do the estimate.
I look under the house myself
I come out and get down in the crawl space before I put a number on anything, so the price reflects your vents, your old insulation and your equipment, not a guess.
The work goes in the right order
Old problems get fixed before new insulation covers them, because insulation laid over open leaks or damp wood doesn't do what you paid for and just hides the trouble.
Straight answers on what's worth doing
If something under your house isn't worth doing, or isn't ours to do, I'll tell you plainly instead of selling you work your house doesn't need.
How we insulate a crawl space
On the first visit I get under the house with a light and look at the vents, the dirt floor, the old insulation, the pipes and anything down there that burns gas or oil. The big choice is whether to seal the crawl space and treat it as part of the house, or insulate under the floor and leave the vents open, and if a furnace or water heater that burns fuel sits down there, it's part of the plan from that first visit, because sealing vents around that kind of equipment and doing nothing else can be dangerous. Once you've picked the approach, our crew pulls out wet or dirty insulation, seals the gaps around pipes, wires and the edge of the floor, lays down a ground cover, a heavy plastic sheet that keeps dirt-floor moisture down, if the plan calls for it, and puts in the new insulation before cleaning up. Then I walk through the finished work with you.
A crawl space is usually one piece of a cold floor or a drafty room. If air is slipping in around the rim of the house or through holes for pipes and wires, our air sealing services close those gaps so the insulation isn't fighting a draft, and if the rooms above still feel cold through the outside walls, wall insulation is often the next thing worth looking at.
When crawl space insulation is worth a look
Pipes that freeze in a cold snap
Water lines running through a cold crawl space are usually the first to freeze, and insulating and closing up the space keeps them out of the coldest air.
A furnace or ducts under the floor
If your heating equipment or ductwork lives down there, sealing and insulating the crawl space usually pays off, because the heat you're already paying for stops leaking into cold air.
A damp or musty smell
A musty smell coming up through the floor, or sagging wet insulation, means moisture is getting in, and that has to be sorted out before any new insulation goes down.

Tell us the rough size
A rough length and width of the crawl space, or the footprint of the house above it, helps me plan the visit and bring the right tools to look.
Mention any radon test results
If you've tested for radon, send the number along, because it helps decide what kind of ground cover and sealing make sense down there.
Say what's under the floor
Let us know if a furnace, water heater or ductwork sits in the crawl space, because equipment that burns gas or oil changes which approach is safe.

Questions about crawl space insulation in Altoona
Here are straight answers to what Altoona homeowners usually ask before we insulate or seal the crawl space under their house.
Should I seal my crawl space or insulate under the floor in Altoona?
Usually a sealed crawl space, insulated and treated as part of the house, is the better choice, because open vents let humid air reach cold floor joists and condense on the wood. Altoona falls in the state's climate zone 5, cold enough that frozen crawl space pipes are a real worry. With foam board on the walls of a sealed space, the floor above needs no insulation.
Can I just close off the crawl space vents to keep the cold out?
Closing the vents by themselves usually leaves a crawl space damper, not drier, so it takes more than blocking the openings. A crawl space always needs a way to dry out, and one of the best is a small amount of conditioned air from your heating and cooling system. We plan that air supply into any sealed crawl space job.
How much does crawl space insulation cost in Altoona?
Across the US, crawl space insulation usually costs about $3 to $6 per square foot, a national guide rather than a local quote. Sealing the whole space usually costs more than insulating under the floor of a vented one, and wet or dirty insulation that has to come out adds to it. I'll price your own crawl space when I come out.
Should I test for radon before insulating my crawl space?
Yes, testing first makes sense, because a test is the only way to know if your house has high radon, even without a basement. The state says about 40% of homes tested in Pennsylvania come in above the EPA guideline of 4 picocuries per liter. A well-installed ground cover in the crawl space helps hold back soil gases like radon.
Do I need a permit to insulate a crawl space in Altoona?
Pennsylvania's building code says the owner, or someone they authorize, has to get a building permit before starting construction work, and rules differ between cities, boroughs and townships. We check with the local code office before we start and go over what we learn with you, and if a permit is needed, we work with you to have it in place before any work begins.
Who is allowed to insulate a crawl space in Pennsylvania?
Most home improvement contractors have to register with the Pennsylvania Attorney General's Office and carry minimum insurance under the state's contractor licensing rules, and some places add their own rules, so in Altoona it's worth asking the city. State law also requires their contracts to meet consumer protection rules, so ask how yours does. We're licensed and fully insured.
