D&K Davenport Insulation Company is an insulation contractor in Davenport, IA, and most calls start with a cold room, a hot upstairs or a power bill that keeps climbing. We offer 16 services so we can go after the actual cause, whether that's an attic short on insulation, gaps letting air through or a damp crawl space. The price mostly turns on how much area we cover, what's already up there and whether it has to come out first, and whether foam or loose fill fits the spot. The schedule depends on the same things, plus anything like a roof leak that has to be fixed before we insulate. The estimate at your house gives you your own figure.

Spray foam insulation
We spray foam into rim joists, the band of wood where the house sits on the foundation, plus walls and rooflines, where it seals air and insulates in one pass. It costs more than loose fill, so we suggest it where gaps are hard to reach or the ductwork runs through the attic.

Attic insulation
Hot upstairs in summer and cold in winter? We check how many inches are already up there, seal the gaps, and bring the attic up evenly out to the edges without burying the eave vents.

Blown-in insulation
Blown-in insulation is loose fill we blow through a hose, so it settles into corners and around framing that batts leave open. For topping up an open attic, it's usually the best value.

Home insulation
This is for homeowners who want the whole house looked at, not just one room. We go through the attic, walls, crawl space and basement and tell you which ones are worth doing first.

Insulation removal
If the old insulation is soaked or full of droppings, putting new material on top just hides the problem. We bag it out and clean the space before anything new goes in.

Crawl space insulation
Cold floors over a crawl space usually mean cold air is moving under the house. We insulate the crawl space walls or the floor above, whichever fits how yours is built.

Wall insulation
We fill the empty wall cavities of older houses through small holes and plug them afterward, so outside walls stop feeling cold to the touch.

Air sealing services
Air sealing is closing the gaps around pipes, wires, rim joists and doors before we insulate. Without it, the insulation spends its life fighting a draft.

Basement insulation
We insulate basement walls and rim joists so a finished room, or one you plan to finish, stays warmer. If the walls are wet, we'll tell you to fix that first.

Closed-cell foam insulation
Closed-cell foam is a dense foam that also blocks moisture, which makes it a good fit for crawl space walls and other spots near damp. It's the pricier choice, so we use it where that moisture block matters.

Open-cell foam insulation
Open-cell foam is a softer, lighter foam that fills odd-shaped cavities and seals them as it goes. It belongs in dry spaces like interior walls and rooflines, not anywhere that gets damp.

Commercial insulation
Building owners and managers call us for offices, shops and rentals. We insulate and air seal them in the same order we use on houses.

Crawl space vapor barrier
We lay heavy plastic sheeting over the crawl space dirt and seal the seams, so ground moisture stays out of the space under your floors.

Vapor barrier installation
A vapor barrier is a sheet that keeps moisture from moving into walls and ceilings. We put it on the side your house needs it, because one in the wrong place traps water instead of stopping it.

Attic air sealing
Is the room over the garage always cold? The attic above it often has open gaps around can lights, pipes and the hatch, and we seal those before any insulation goes on top.

Retrofit insulation
Retrofit insulation adds to a house that's already built and lived in, without tearing out walls or ceilings. It's for older houses that went up with little or none.

Why people hire our crew
Straight answers before any insulation
If your roof leaks or a wall is wet, I'll tell you to fix that first, because insulation over it just hides the problem. Sometimes that means you don't need us yet, and I'd rather say so than sell you the wrong fix.
Gaps sealed before insulation goes in
We seal around pipes, wires, can lights and the attic hatch before adding anything, so the insulation isn't fighting a draft. That's how the money you spend ends up as a warmer house instead of a deeper pile.
A crew that cleans up
The crew covers the path to the attic and cleans up its dust and scraps before we leave, so the only thing you notice afterward is that the drafts are gone. Your satisfaction, guaranteed.

How a job goes with us
Call or send the form
Call us or fill out the form and tell us what you're noticing, whether it's a cold room, a drafty upstairs or a high bill. If you know how old the house is or what's already in the attic, mention it. We get back to you within one business day to set a time.
I come out and look
I come out myself and look over the attic, walls, crawl space or basement, wherever the problem points. I'll show you anything that has to be fixed before insulation, like a leak or wet framing, and leave you a free estimate with no obligation. If your job needs a permit, I'll tell you up front and we handle it with the city.
The crew does the work
If you go ahead, my crew works in order, taking out old or damaged material first if it has to go, sealing the gaps, then laying insulation in evenly to the edges with the vents kept clear. On spray foam jobs, we tell you the re-entry time, when it's safe for you, the kids and pets to come back in, before we start.
We walk it together
When the work's done, I walk the finished job with you before we pack up. You see what went in, where we sealed and how the space was left, and you can ask about anything that doesn't look right to you while we're still there.
