Spray foam insulation
Foam costs more and seals air while it insulates. In most attics, sealing gaps and topping up loose fill wins, unless your ductwork runs up there, and then foam usually earns its price.
Insulation contractor in Decatur, IL - attics and crawl spaces done in the right order
Prime Springfield Spray Foam Insulation is an insulation contractor based in Springfield, IL, insulating attics, walls, crawl spaces and basements in Decatur. We seal gaps, pull out insulation that's past saving and add what the house needs.
What insulation work in Decatur usually involves
We're based in Springfield and work across central Illinois, Decatur included, the same as Taylorville and the cities around them. A lot of what we see here is older housing, places like the historic West End, where the attic has a few inches that settled decades ago and the upstairs runs hot all summer. We also see newer houses where whoever blew in the attic covered the middle and forgot the edges. The price comes down to how much is already up there and whether it can stay, how many gaps need sealing, and whether foam makes sense for your house. The schedule turns on what has to happen first, like pulling out wet or dirty insulation or waiting on a roof repair. I give you both from what I find at the estimate.
The city lists work within a floodplain among the jobs that need a permit, so if your lot sits in one, tell me at the estimate. Down in the crawl space, the ground decides the job, because insulation laid over wet dirt just rots in place.
I see it before we price it
I come out for every estimate myself and get into the attic or crawl space, because the inches already up there, and what shape they're in, decide the job.
Leaks and damp come first
If the roof leaks or the crawl space stays wet, I'll tell you to fix that before we insulate. I'd rather you wait a month than pay for the job twice.
Ask who can pull the permit
Decatur requires a contractor on permit work to be licensed and registered with the city's Building Department, and that contractor can only pull a permit while the license is in good standing.
Insulation services we offer in Decatur
Attic insulation
We measure what's already up there, keep it if it's dry and clean, and even out the coverage so the edges get as much as the middle, not the other way around.
Blown-in insulation
Blown-in is loose fill sent through a hose into the attic or walls. We keep the eave vents clear before we start, so the new layer doesn't choke off the attic's air.
Home insulation
When the whole house runs drafty, I go through the attic, walls and crawl space and tell you which one is letting the most heat out before we touch anything.
Insulation removal
Insulation that got soaked or filled with droppings comes out before anything new goes in, because covering it keeps the smell and the damage right where they were.
Crawl space insulation
Cold floors usually start below them. We check the crawl space for standing water first, then insulate so the floors above stop pulling the heat out of your feet.
Wall insulation
Older Decatur houses often have empty or slumped wall cavities. We fill them through small holes we patch afterward, so the outside walls stop feeling cold to the touch.
Air sealing services
Air sealing is closing the gaps before insulating. Around the house that means rim joists, pipe holes through the floor and the seam where the room over the garage meets the rest.
Basement insulation
We insulate rim joists and foundation walls after checking for seepage, because foam or batts on a wet basement wall just hold the water against the concrete.
Closed-cell foam insulation
Closed-cell foam is dense foam that blocks moisture as well as heat. We use it on rim joists, crawl space walls and other spots that see damp.
Open-cell foam insulation
Open-cell foam is softer and lighter, and it fills odd rooflines and wall cavities well. We keep it to dry spaces, since it doesn't stop moisture the way closed-cell does.
Commercial insulation
Landlords and property managers call us for rentals and small commercial buildings, and I look over each unit or space before we price it, the same as a house.
Crawl space vapor barrier
We lay a vapor barrier over the crawl space dirt to keep ground moisture out of the floor framing, once any standing water down there has been dealt with.
Vapor barrier installation
Where a wall, ceiling or basement needs a vapor barrier, we put it on the side the house needs it, because one on the wrong side traps moisture in the wall.
Attic air sealing
Before we add anything to an attic, we seal around the hatch, the plumbing stacks and the can lights, so the new insulation isn't fighting a draft coming up from below.
Retrofit insulation
Retrofit work adds insulation to a finished house without tearing out walls. We pick the method by what's behind the drywall, which I check before pricing anything.

Permits, inspections and insulation in Decatur
Straight answers on permits, inspections and when you can get back in the house after an insulation job in Decatur.
Do I need a permit for insulation work in Decatur, IL?
Maybe, so we check with Decatur's Building Inspections division before we start, and if a permit is needed, we take care of it. That office issues permits inside the city limits. Its list names roofing, decks, electrical work, furnaces, water heaters and siding among other work, which is why we ask about insulation instead of guessing. You can reach it at 217-424-2787.
What happens in Decatur if work that needs a permit starts without one?
The city issues a stop work order, and the job sits until the proper permit is pulled. If no permit follows, the city files a notice of non-compliance against the property, which puts a lien, a legal claim, on your house. That's a lot of trouble to skip a phone call, so we make the call first.
How soon can I get a building inspection in Decatur?
Usually the next day, if the request goes in before 4 p.m. the day before and an inspector is free. The city sets inspection routes by area, not by who asked first, so yours can slip a day. If your job needs an inspection, we schedule it and plan the work around it.
Do I have to leave my Decatur house during spray foam insulation?
Usually yes for spray foam, and usually no for blown-in or air sealing. Fresh foam gives off fumes while it cures, so you, the kids and the pets stay out until the re-entry time, the wait before it's safe to come back in. That depends on the product, and I'll give you the time at the estimate.
