Where should I start insulating my house?
Home insulation in State College means adding insulation where your house loses the most heat, usually the attic, the floor over a crawl space and the rim joists, the boards sitting on top of the basement wall, after sealing the gaps that let air slip through. Done in that order, it makes the house less drafty and easier to keep comfortable.
Most of the calls I get start with a drafty older house, a room over the garage nobody wants to sit in, or a power bill that keeps creeping up. The price turns mostly on how many areas need work, how much is already there and how easy the attic and crawl space are to reach, while the schedule depends on the size of the job, any permit and whether foam means time away from home. I'd want to see the house first, and the written estimate after my visit gives you the figure for yours.
How we handle home insulation, attic to basement
I start by looking at the whole house, attic to basement, and telling you which areas will make the most difference first, so your money goes where you'll feel it soonest. Before we seal anything, I talk through your gas or oil furnace, water heater and anything else that burns fuel, because a tighter house changes how much fresh air they get. Then our crew protects your floors and air seals, closing the gaps around light fixtures, pipes, wires and the attic hatch, so the new insulation isn't fighting a draft, and we keep the eave vents open so the attic can still breathe. The insulation goes down last, at full depth out to the edges and not just piled in the middle, and if you'd like your finished rooms left alone, we can talk about loose fill that goes in without tearing anything out.
Some houses need work before or beside the attic. If what's up there now is wet or soiled, we take it out first with insulation removal, because fresh material over spoiled material leaves the problem in place. When the chill comes up from under the house, crawl space insulation deals with it from below.
Air sealing and blown-in loose fill
This suits most attics, because blown-in insulation, loose fill blown through a hose, spreads evenly around joists and wiring once the gaps underneath are sealed. It's the approach I recommend most often, since it usually does the job for less than foam.
Spray foam for ducts and damp spots
Foam costs more, but it seals air while it insulates, so it earns its price when ductwork runs through the attic or a rim joist needs a tight seal. Closed-cell foam, a dense foam that blocks moisture, is the usual choice for damp spots below the house.
Home insulation permits and houses in State College
The Centre Region Code Administration says a permit application should be made before any construction or remodeling work begins, and whether your insulation job needs one isn't something I'd guess at. So we check with the office that covers your address, and where a permit applies, we prepare the paperwork, walk you through it and keep you posted on where it stands. If you'd like to ask the office yourself, it's at 2643 Gateway Drive and can be reached at 814-231-3056.
Many of the houses we work on here are older, with a few inches of tired insulation in the attic and open gaps around chimneys and plumbing. We see the same kind of houses on jobs in Bellefonte and Tyrone, and we work across the cities around State College, so please ask if yours isn't listed.

Frequently asked questions
Do I need a permit for insulation work in State College?
It depends on the scope of the work, so we check with the Centre Region Code Administration for your address before anything starts. Where a permit applies, we take care of the paperwork, as described in the State College section above.
What is the best insulation for an older house in State College?
For most older houses, loose fill is the most flexible choice, because it fills any space without disturbing the structure or finishes. Blankets, sold as rolls or precut batts, are the most common type in US homes and suit open framing that's easy to reach, like an unfinished basement ceiling. I'd want to see your house before picking.
Should air leaks be sealed before adding insulation?
Yes, in an existing vented attic, sealing every gap in the attic floor comes first, because insulation alone still lets air move through cracks and holes. That sealing also helps keep moisture problems out of the attic. Once a house is tighter, fuel-burning appliances need enough fresh air, since without it they can give off carbon monoxide, so ventilation gets planned along with any sealing.
Do I need to leave home during spray foam insulation?
Yes, Consumer Product Safety Commission staff say to stay out during the install and for at least 24 hours afterward, so please line up a place to stay before we book the day. They also suggest that anyone with asthma, respiratory allergies, skin conditions or a past sensitivity to isocyanates, chemicals used in the foam, review the product information first and consider other insulation if needed. We go over the safety steps and your re-entry time, the point you can come back inside, before we start.
How much does home insulation cost in State College?
I can't give you a fair number until I've seen the house, because the price turns on which areas need work, how much insulation is already there, how hard those spots are to reach and whether old material has to come out first. Foam costs more than sealing and loose fill, and working around finished rooms adds time. The written estimate after my visit gives you the figure for your house.
How do I know if my house needs more insulation?
Drafts, a hot upstairs, cold floors or a climbing power bill are the usual signs, and the sure way to know is to have a contractor check what's there and its R-value, how well it slows heat. I measure how many inches are in the attic and look over the crawl space and basement. Nationally, insulating along with sealing air leaks saves homeowners up to 15% on heating and cooling on average, so treat that as a ceiling, not a promise for one house.

If mice, squirrels or an old roof leak got to the stuff in your attic, clearing it out lets us see the framing and gives the new layer a clean, dry start.
Crawl space insulation
Cold floors in the rooms above an open or vented crawl space usually mean heat is slipping out underneath, and insulating down there makes those rooms easier to keep comfortable.
