Request an estimateSilvis houses: old attics, mixed foundations
Silvis sits between East Moline and Colona on the Illinois side, and most of our calls here come from older houses. Many of the homes near the center of town were built long before anyone blew insulation into an attic, and what's up there now has usually settled thin or been patched by a few different owners. Farther out you'll find newer houses, where the attic is often fine and the trouble is a cold room over the garage or a hatch nobody ever sealed.
That mix shapes the job. In an older house a cold room is often a draft and not a thin layer, so we look under the old material and find the gaps before adding anything, and houses on a crawl space get the floor and the moisture checked first.
What to expect on an insulation job in Silvis
Building permits in Silvis come from the city's Inspections Department, and any wiring, plumbing or heating and cooling work needs its own separate permit. The office is open 8 to 9 in the morning and noon to 1 on weekdays, or by appointment, so if your job needs a permit we take care of it with the city early and tell you about it up front, before the crew is booked. Before you hire anyone, you can ask whether they're registered with the city this year, since every contractor working here has to be.
What moves the price is mostly what I find in the attic: how many inches are already up there, whether old material is wet or dirty and has to come out first, how many gaps need sealing, and whether loose fill will do or the job calls for foam. The schedule turns on that same prep plus any permit, and because I come out to look at the job and write the estimate myself, the figure and timing you get are for your house and not a guess over the phone. We're based in Davenport and do the same work in Moline and Rock Island, along with plenty of cities that don't have their own page here.
Services in Silvis, IL
Attic insulation
Older Silvis attics usually have a few inches of settled material that's deep in the middle and thin at the eaves, which is backward from where the heat gets out. We bring the edges up to match without burying the eave vents, so the attic still breathes and the framing stays dry.
Air sealing services
In a drafty older house the cold usually comes in around can lights, pipes, the chimney and the attic hatch, and no amount of insulation stops air moving through a hole. Our air sealing services close those gaps first, before anything new goes down on top.
Insulation removal
When old insulation has been soaked by a roof leak or filled with droppings, laying new material over it just buries the problem. We pull it out and clean up, and we won't put anything back until the leak is fixed.
Wall insulation
Plenty of older houses here were built with nothing in the walls, which is why the outside corner rooms stay cold no matter what the thermostat says. We fill those empty cavities through small holes and patch them, so you're not tearing off siding or plaster.
Crawl space vapor barrier
Homes on crawl spaces often have bare dirt underneath, and the damp from it shows up as cold floors and a musty smell upstairs. We lay a sealed vapor barrier over the ground first, because insulation over wet dirt doesn't hold up.
Spray foam insulation
The room over the garage and attics with ductwork running through them are where foam earns its higher price, because it seals air while it insulates. Everywhere else, sealing the gaps and topping up loose fill usually does the job for less, and I'll tell you which one your house needs.

Frequently asked questions
Do I need a permit to insulate my house in Silvis, IL?
We check that before any work starts, and if your job needs a permit, we take care of it with the city and tell you about it up front. It's worth getting right here, because the city's posted rules say starting work that needed a permit brings a penalty fee equal to the permit fee for the whole project, not just the part already done.
Can I pull my own permit to insulate my house in Silvis?
Yes, if you own and live in a single family detached home, the city lets you get permits and do the work on the house and its garage or shed yourself. Anyone else doing the work, contractors included, has to be registered with the city first.
Does an insulation contractor have to register with the city of Silvis?
Yes, the city's posted rules say anyone doing business as a contractor in Silvis has to register with the city every year, at $50.00 a year due on or before January 1. Registered contractors also keep a $10,000.00 minimum code compliance bond and liability insurance of $100,000.00 for each property damage occurrence and $300,000.00 for each injury occurrence. It's fair to ask any contractor you're considering whether they're registered for this year.
How much does it cost to insulate an older house in Silvis?
There's no honest number until I've seen the house, and the estimate gives you one in writing for your house. In older Silvis homes the extra cost usually isn't the new insulation, it's the prep, like pulling out soaked or dirty material and sealing gaps first. Sometimes the right fix is smaller than you expected, like sealing the hatch and a few can lights, and I'll tell you when that's the case.
How long does attic insulation take in Silvis, and when can we go back inside?
The crew's time depends on how much removal and sealing your attic needs, and you'll get the schedule with the estimate. With blown-in insulation, which is loose fill blown through a hose, most families stay home and just keep kids and pets clear of the work area. Spray foam is different, because everyone stays out until the foam maker's re-entry time has passed, and I'll give you that time before we book the day.
What is the best way to insulate a damp crawl space in Silvis?
Fix the water first, then cover the ground with a sealed vapor barrier, then insulate, because insulation over wet ground just traps the problem. Rock Island County says the area's creeks, the Rock River and the Mississippi can put some homes in a flood hazard area, and Silvis has its own rules for building in those areas, so if your house is near water we raise that with the city before crawl space work. If I find standing water down there, I'll tell you to deal with it before you spend money on insulation.
