Request an estimateDeWitt: older houses, newer subdivisions
DeWitt is a small city with a real mix of houses. Near the center we find older homes with a patchwork of insulation from different decades, and on the edges there are newer houses that were built tighter but often got skimped on in the attic. Farmhouses outside town bring their own mix of cold floors and old crawl spaces.
It works a lot like Geneseo on the Illinois side. The older houses usually need the old material checked before anything new goes up, and the newer ones usually need the gaps sealed and the attic edges filled out, so the age of your house decides where we start.
Before an insulation job starts in DeWitt
The City of DeWitt issues building permits here, and when it isn't clear whether a job needs one, the city asks you to check first with its Building Official, TJ Appleby, at 659-3811. If your job needs a permit, we take care of it with the city and tell you about it up front. Inspections need 24 hours notice, so we build that into the schedule instead of letting it hold up the crew. We're licensed and insured.
Price turns on the attic more than anything. A bigger or harder-to-reach attic costs more, so does pulling out old insulation that's wet or full of droppings, and foam costs more than sealing gaps and topping up loose fill. The schedule mostly depends on whether old material comes out first and whether the job needs a permit. I write your number at the house after I've been up the ladder, the same way we do it in Eldridge and back home in Davenport.
Services in DeWitt, IA
Attic insulation
A lot of attics we open in DeWitt are deep in the middle and thin at the edges, which is backward because the edges are where the cold gets in. We fill the eaves without burying the vents and bring the whole attic up evenly.
Attic air sealing
Older houses here usually have open gaps around can lights, pipes and the attic hatch, so new insulation ends up fighting a draft. We seal those first, because that's often what actually fixes a hot or drafty upstairs.
Insulation removal
When old insulation in an older home is soaked or full of droppings, putting more on top just buries the problem. We bag it out and clean up before any new material goes in.
Wall insulation
Older houses near the center of town often have walls with little or nothing in them, which is why some rooms stay cold no matter what's in the attic. We fill the wall cavities and patch the holes so you'd hardly know we were there.
Crawl space insulation
Older homes and farmhouses around DeWitt often sit over a crawl space that leaves the floors above it cold. We check for moisture first, then seal and insulate so the floor warms up.
Open-cell foam insulation
The room over the garage and finished attic rooms in newer DeWitt houses tend to have tight, awkward spaces that loose fill can't reach. Open-cell foam insulation fills those spaces and seals air as it goes, so we use it where it's worth the higher cost.

Frequently asked questions
Do I need a permit to insulate my attic in DeWitt, Iowa?
The city's permit list doesn't settle it, because insulation isn't on it and the city calls the list only "some items." It names work like a furnace, a fence, decks and sheds larger than 10 x 12, which you can see on the city's permits page. The Building Official mentioned above is the one to ask, and if the answer is yes, we handle the permit.
How do I apply for a building permit online in DeWitt?
You apply through Cloudpermit, the online system the city uses to take and track building permits. It's open to residents, builders and businesses in the communities the city serves. On a job we're doing, the permit is ours to file, so you usually won't need to log in yourself.
How much does insulation cost for a house in DeWitt?
Most of the price comes down to whether we can add to what's already there or have to start over. Sealing the gaps and topping up sound insulation sits at the low end, and pulling out soaked or dirty material and switching to foam sits at the high end. I'll give you your own figure after I've been in the attic.
How long does an attic insulation job take, and do we have to leave the house?
With blown-in insulation, which is loose fill blown through a hose, you can usually stay home while the crew works, and the job runs longer when old material has to come out first. Spray foam is different, because you stay out until the re-entry time the foam maker sets, so kids and pets need somewhere to go. I go over the timing with you at the estimate.
What causes the room over the garage to be so cold in a DeWitt house?
Usually it's air leaking through gaps in the floor and outside walls of that room, plus insulation that's thin or missing where the room sits over the garage. Piling more on top without sealing those gaps rarely fixes it. We seal first, then fill the floor and walls, and sometimes foam is the better fit there.
What is the best way to insulate an older house in DeWitt?
Check what's up there, seal the gaps, then add insulation, in that order. Wet or dirty material comes out, gaps around can lights, pipes and the hatch get sealed, and the eave vents stay open so the attic can breathe. Foam costs more and seals air while it insulates, but sealing and topping up loose fill usually wins unless your ductwork runs through the attic, and if the roof leaks, I'll tell you to fix that first.
