Request an estimateBettendorf: older attics, newer bonus rooms
Bettendorf sits right next to Davenport along the river, and on our jobs it reads like two different cities. Near downtown and the riverfront, the houses are older, and the attics usually got a few inches of insulation a long time ago that has since settled and gone thin. Farther from the river, it's newer subdivisions with bigger houses, finished basements and bonus rooms over the garage.
So the job here usually starts with how old the house is. In the older homes we're sealing around pipes, wiring and the hatch before we top up, and in the newer ones the call is usually about one room that never feels right.
Working in Bettendorf, from the permit to the attic
When an insulation job in Bettendorf needs a permit, it comes from the city's building official, and applications go through the city's Permitting & Licensing portal, so waiting on it can set your start date. If your job needs one, we take care of it with the city and tell you up front. Before you hire anyone, ask for their Iowa contractor registration, and know that the city also handles its business licenses through that same portal. We're licensed and insured, and I'm the one who comes out to look at your house.
Bettendorf runs on Iowa rules, which isn't true of Moline across the I-74 bridge, so I don't assume what's right on a job over there is right here. Your price mostly turns on what's already in the attic, what has to come out and how many gaps need sealing before anything new goes in, and the schedule turns on any permit and on whether we're blowing in loose fill or spraying foam. The estimate puts your own number on it.
Services in Bettendorf, IA
Attic insulation
A lot of older Bettendorf attics have insulation that's deep in the middle and thin at the edges, which is backward. We measure what's up there and bring the whole attic up evenly, eaves included, without burying the vents.
Blown-in insulation
Most attic top-ups we do here use blown-in insulation, loose fill blown through a hose, because it settles in around joists and wiring where batts won't fit. We blow it in only after the gaps underneath are sealed.
Attic air sealing
Can lights, plumbing pipes and the attic hatch leak warm air in old and new houses alike, so new insulation ends up fighting a draft. We seal those gaps first, because it's the step that gets skipped most often.
Insulation removal
When the old insulation in an older house is soaked from a past roof leak or full of droppings, putting more on top just hides the problem. We pull it out and clean up, and if the roof still leaks, I'll tell you to fix that before we insulate.
Crawl space insulation
Cold floors over a crawl space are a common complaint in older Bettendorf homes and the additions built onto them. We seal and insulate the crawl space so the floor above stops pulling heat out of the room.
Spray foam insulation
Bonus rooms over the garage and attics with ductwork running through them are where foam earns its place in the newer subdivisions. It costs more than loose fill but seals air while it insulates, so we only recommend it where that seal is worth the price.

Frequently asked questions
Do I need a building permit to insulate my house in Bettendorf?
Bettendorf requires a building permit when work builds, moves, adds onto or structurally changes a building, and it's issued only when the work meets the city's zoning rules, so insulating a new addition falls under that permit. A plain attic top-up isn't spelled out by that rule, so I check with the city before we book, and the building permit application is on the city's online forms list. If your job needs one, we handle it and tell you up front.
How do I know if an insulation contractor is registered in Iowa?
Ask them for their Iowa contractor registration, because anyone earning $2,000 or more a year from construction has to register with the state's Department of Inspections, Appeals, and Licensing before doing construction work in Iowa. Only people earning less than that, or working on their own property, are left out, so a crew insulating houses for pay should have it. We're licensed and insured.
Does a contractor from the Illinois side need anything extra to work in Bettendorf?
Yes, with few exceptions a contractor whose main place of business is outside Iowa has to file a $25,000 bond to register with the state, and opening a branch office in Iowa doesn't change that. It's worth asking about when you're comparing bids from both sides of the river. We're based in Davenport, so Iowa is home for us, and we work in Illinois cities too.
How much does it cost to insulate an attic in Bettendorf?
The cost turns on what's already in your attic and what has to happen before new insulation goes in. How many inches you have now, whether old material is soaked or dirty and has to come out, how many gaps need sealing and whether you need foam or loose fill all move it. I give you a real number after I've been up there.
How long does attic insulation take, and do we have to leave the house?
A top-up over sealed gaps is a short job and you can usually stay home, while pulling old material out first adds time. Spray foam is different, because everyone, kids and pets included, stays out until the foam maker's re-entry time has passed, which is how long the maker says to wait before coming back inside. I'll tell you which applies to your house at the estimate.
What causes a cold room over the garage?
Usually it's gaps and thin insulation in the floor and outside walls of that room, so cold air from the garage works its way in. It's one of the most common calls we get from the newer Bettendorf subdivisions. We seal the gaps first and then insulate, and where ductwork runs through that space, foam is often the better fit.
