Insulating Connell homes, attic to crawl space
We're an insulation contractor based in Kennewick, WA, and Connell is one of the smaller cities we drive up to, north of Pasco along Highway 395. It's a farm town, and our calls here come from homeowners with cold floors, landlords getting a rental ready, and owners of shops and small businesses in town.
Many of the houses we see here are single-story, with an attic over the living space and a crawl space underneath, so most jobs mean working at both ends of the house. What's already there sets the plan, the price and how long we're on site. That mainly means how many inches you have now, whether old material has to come out first and how many gaps need sealing, and we won't know all of it until the hatch is open. You get your own figure in the written estimate after I've looked.
What we do on Connell homes and shops
Spray foam insulation
Metal shops and outbuildings on Connell farm lots take spray foam well, because it bonds to steel and seals seams as it insulates.

Single-story houses here usually lose the most heat through the attic, so we seal the gaps first and carry full depth to the edges.

Blown-in fill, loose insulation sent through a hose, is how we top up most Connell attics that have settled thin over the years.

Not sure where the cold gets into your house? We go through it attic to crawl space and tell you what to fix first.
Explore Home insulationInsulation removal
In a farm town, mice find their way into attics, so soaked or dirty insulation comes out before anything new goes in.

Cold floors here usually start in the crawl space, so we insulate under the floor and along the framing that sits on the foundation.

Older houses in town sometimes have little or nothing in the outside walls. We can fill them through small holes without tearing out drywall.

Drafty rooms in older Connell houses usually come from gaps around plumbing, wiring and floor edges, so air sealing closes those first.

Where a Connell house has a basement, we insulate the foundation walls so the room downstairs stops feeling like a cellar.

In a damp crawl space or a steel shop, closed-cell foam is dense enough to block moisture while it insulates.

On additions and bonus rooms around town, open-cell foam fills odd-shaped framing and quiets noise, where moisture isn't the worry.

Shops, offices and small businesses in Connell get the same care we give houses, and we plan the work around your hours.

Bare dirt under many houses here sends moisture up into the framing, so we cover it with heavy plastic sealed at the seams.

On a room over the garage, we put the vapor barrier on the heated side so moisture won't collect inside the wall.

In Connell attics, we seal around can lights, pipes and the attic hatch before insulation goes down, so the new layer isn't fighting a draft.

Houses built here with little insulation can be brought up without a remodel, working through the attic, the crawl space and small wall holes.

What Connell houses ask of an insulation job
I come out to look at every Connell job myself, and our installers do the work with me checking it before we finish. We've been insulating houses from our base in Kennewick since 2013, and I care most about the parts nobody sees once we leave.
Full depth out to the far corners
The low edges of an attic are hard to reach, so they often end up thin. We crawl out to them and keep the vents along the roof edge clear so the attic can breathe.
A written plan before you agree
After I look at the house, we write out what we plan to do and why, so you know what you're paying for before you say yes.
Problems named before we start
If there's a roof leak, a wet crawl space or wiring that needs an electrician, I'll tell you plainly instead of covering it with new insulation.

Questions we hear from Connell homeowners
Who issues building permits in Connell, WA?
Franklin County's building official and inspectors issue building permits for Connell projects, and the county's building staff handle the reviews and the site inspections. They work to the building code the city has adopted, so the rules are Connell's even though the county does the checking. You can see how it works on the city's building permits page, and when one of our jobs needs a permit, we take care of it with the county.
Do I need a permit to add insulation to my house in Connell?
Insulation isn't one of the examples on the city's list of projects that need a building permit, so we ask the Franklin County Building & Planning Department before any work starts. Remodels and plumbing or mechanical work are on that list, so if insulation is part of a bigger project, that project may need its own permit. Rules differ from city to city, which is why we ask instead of assuming, and we handle the permit when one is needed.
Does a contractor working in Connell need a city business license?
Yes, the City of Connell requires a license for every business located inside city limits or doing business there, renewed each year. A new business pays $30.00, while a business based outside the city, as we are in Kennewick, pays $0 until its yearly income from work in Connell passes $4,000 and $30 above that. We're fully licensed and insured, and it's a fair question to put to any contractor you're considering.
How much does it cost to insulate a house in Connell?
Your price comes from a written estimate after I see the house, because it turns on what's already in the attic or crawl space and what has to happen before new insulation goes in. The biggest choice is foam versus loose fill. Foam costs more and seals air as it insulates, but sealing the gaps and topping up blown-in fill usually comes out ahead, unless your ductwork runs through the attic, where foam earns its cost.
How long does attic insulation take, and do we have to leave the house?
For blown-in fill and air sealing you can usually stay home, and how long we're up there depends on the attic's size, how much sealing it needs and whether old insulation comes out first. Spray foam is different, so everyone, kids and pets included, stays out until it's safe to come back in, which is the re-entry time the foam maker sets. I'll tell you what to expect for your house at the estimate, before anything is booked.
What causes cold floors and drafty rooms in a Connell house?
Usually it's air moving through gaps more than a shortage of insulation, though thin or settled insulation makes it worse. An open crawl space lets cold air reach the floor framing, and leaks in the ceiling let warm air escape and pull more cold air in behind it. At the estimate I look at both ends of the house, because fixing only one usually leaves the room feeling about the same.
