What insulation work looks like

State College, where we're based
Life in State College runs through places like Sunset Park, with its pavilions, and the wooded walking paths of Lederer Park, two of the Borough's parks. The Borough of State College handles local government here, and most of the calls we get, here and nearby, come from drafty older houses, families planning a remodel and a few property managers.
Before a job starts, it helps to know who covers what. The Borough's Planning Department issues zoning permits, which are required before building, altering or tearing down any structure, and Centre Region Code Administration handles building permits on the Borough's behalf. Pennsylvania doesn't license most construction contractors, but anyone running a home improvement business has to register with the state Attorney General's office unless exempt, with an exception for individuals doing less than $5,000 of home improvement work in a calendar year. Whether your insulation work needs a permit depends on the job and the address, so we check with the office that covers your house and take care of the paperwork where one applies.
Insulation contractor services in State College, PA
Apex State College Spray Foam Insulation is an insulation contractor in State College, PA, with 16 services covering attics, walls, basements and crawl spaces. The price usually turns on how much is already up there, whether old or damaged insulation has to come out first, how many gaps need sealing and which material suits the space. Foam costs more and seals air as it insulates, but sealing the gaps and topping up loose fill is usually the better buy unless your ductwork runs through the attic. The schedule mostly depends on prep, like removal or a repair that has to happen first, and on whether a permit applies. Your free written estimate puts the numbers for your house in front of you.
Spray foam insulation
Spray foam expands to fill wall cavities and rafter bays, sealing air as it insulates. It costs more than loose fill, so we'll say plainly where it's worth it.
Attic insulation
Hot upstairs in summer and cold in winter? We seal the attic floor first, then bring the insulation up evenly, full depth out to the edges where it's usually thinnest.
Blown-in insulation
Blown-in insulation is loose fill we blow through a hose, and it's the usual way to top up an attic that already has a few inches.
Home insulation
Not sure where your heat is going? We look at the attic, walls, basement and crawl space together and tell you which to fix first and which can wait.
Insulation removal
When old insulation was soaked by a roof leak or is full of droppings, we take it out before anything new goes in, so the problem doesn't get covered over.
Crawl space insulation
Cold floors over a crawl space often mean the space below is open to outside air. We insulate the walls or the floor above, depending on how your crawl space is built.
Wall insulation
We fill the walls of finished rooms by blowing insulation through small holes, then patch them, or insulate open walls during a remodel before the drywall goes up.
Air sealing services
What is air sealing? It's closing the gaps where air leaks through the house, around pipes, wires, outlets and windows, so new insulation isn't fighting a draft.
Basement insulation
We insulate basement walls and the rim where the house framing sits on the foundation, a common spot for drafts and cold floors above.
Closed-cell foam insulation
Closed-cell foam is dense foam that blocks moisture as well as air, so we use it in basements, crawl spaces and other spots where damp is part of the problem.
Open-cell foam insulation
Open-cell foam is a lighter, softer foam that fills odd-shaped roof and wall cavities and dulls sound between rooms, but it isn't the pick for damp spots.
Commercial insulation
For property managers and building owners, we insulate and seal offices, rentals and small commercial spaces, and plan the work around the people using the building.
Crawl space vapor barrier
A crawl space vapor barrier is heavy plastic laid over the dirt floor and up the walls, so ground moisture stays down there instead of soaking into the wood above.
Vapor barrier installation
We put up vapor barriers in basements, walls and attics where the house needs one, and we'll tell you when it doesn't, because a barrier on the wrong side can trap moisture.
Attic air sealing
Before we add anything to your attic, we seal the gaps around can lights, pipes and the hatch and keep the vents along the roof edge clear so the attic can breathe.
Retrofit insulation
Got an older house with little or nothing in the walls or attic? Retrofit insulation adds it to the house as built, without tearing out finished rooms.
Why homeowners hire us
The person who plans it checks it
I come out, look at your house and write the estimate myself. Our installers do the work, and I check it with you before we finish, so the person who made the plan is the one standing behind it.
Problems pointed out in writing first
If I see a roof leak or damp wood, I'll point it out to you in writing before any insulation goes in. Covering a problem only hides it, and it shows up again later.
Sealing and insulating in the right order
We plan the sealing and the insulation as one job, so nothing gets covered before the gaps under it are closed and you aren't paying twice to undo work. Before we begin, we also talk through fresh air, gas and oil appliances and the re-entry time, when your family and pets can come back inside.
Plain options, including smaller ones
We explain your choices in everyday words, and if a smaller job is the better fit for your house, we'll tell you so. You decide with the trade-offs in front of you.
If any of this sounds like your house, please send us a few details or call (814) 996-0002.

How a job goes with us
Call or send the form
Call (814) 996-0002 or send the form with a few lines about your house and what's bothering you, whether that's a drafty room, a hot upstairs or a remodel coming up. We reply within one business day to set a time for me to come out.
I look it over with you
I come out for a free estimate on site, look over the attic, walls, basement or crawl space, and go over what I find with you before anything is written up. Then you get a written estimate with no obligation, so you can take your time deciding.
We do the work in order
If a permit applies, we prepare the paperwork, walk you through it and keep you posted on where it stands. Once anything flagged in the estimate is taken care of, our installers seal the gaps and then put in the insulation, so nothing gets covered before it's ready.
I check it before we finish
When the installers are done, I check the work with you, looking at the depth out to the edges, the sealed gaps and the vents. We clean up, and the job isn't called finished until that check is done.
