What's involved in insulating the walls of a finished house?
Wall insulation in Yakima usually means blowing loose fill into your finished walls through small holes, from inside or outside, and packing each cavity full so cold rooms warm up without new drywall or new siding.
Most calls start with one room that never gets warm, or a power bill that keeps going up while the furnace runs and runs. What moves the price is how much wall there is to fill, what your siding is made of, whether we work from inside or outside, and any sealing or repair that has to happen first. The schedule turns on the same things, plus whether you're re-siding or remodeling anyway, because open walls change the whole approach. I'll put your own figure on a written estimate once I've seen the walls.
How can you tell your walls need insulation?
Outside walls feel cold
Put your hand flat on an outside wall on a cold night, then on an inside wall, and the outside one feels noticeably colder. That usually means the cavity is empty or the old fill has slumped, and every winter you wait, you're paying to heat the yard through it.
One room never warms up
It's often the bedroom over the garage or a corner room with two outside walls. Usually those walls were skipped or left thin, so the furnace runs longer just to keep the rest of the house comfortable.
Drafts at outlets and baseboards
If you feel air at the outlet covers or along the baseboard on an outside wall, air is moving through the wall, not just heat. Insulation alone won't stop that, and the longer it goes, the more warm, damp house air works its way into the wall, where it can start causing trouble.
How we do wall insulation in your house
Before any insulation goes in, I check what's already in a few cavities, usually behind an outlet cover or through a small test hole, and look for old wiring or damp spots that have to be fixed first. We'll tell you whether working from inside or outside makes more sense for your siding, since some siding comes off and goes back cleanly and some doesn't. Our crew drills a small hole into each cavity, and because I framed houses for years, we know to drill above and below the blocking so no section of wall gets missed. Then we blow the insulation in through a hose and pack each cavity full so it won't settle and leave gaps, plug the holes, and put the siding back or patch the drywall.
Filling the walls does the most good when the air leaks are already closed, so we often do air sealing services at the outlets, the top of the walls and around pipes before the insulation goes in. If it's your floors that feel cold, basement insulation may be the better place to spend first, and I'll tell you if I think so.
Closed walls, filled through small holes
This suits most finished homes where the walls are sound and you aren't planning a remodel, since nothing gets torn out. The trade-off is a row of small patches, either outside under the siding or inside on the drywall.
Open walls during a remodel
If you're gutting a room down to the studs anyway, that's the easiest moment to insulate, because the framing is right there and you have more products to choose from, including spray foam. It suits owners already planning the work, but it's not a reason to start one.
Foam board under new siding
If you're re-siding, a layer of rigid foam over the outside covers the studs too, and paired with filled cavities it can make one of the more efficient walls you can build. It changes how the wall handles moisture, which I cover in the questions below.

What happens after you call us about your walls?
Here's how a wall job runs from your first call to the final walk-through, and who you'll be dealing with at each step.
Call or send the form
Call (509) 517-6081 or send the form, and we'll set up a time for me to come out. Mention which rooms feel coldest, since that's where I'll start looking.
I look over your walls
I come out myself, check the walls, attic or crawl space as needed, and explain what I see. You get a written estimate with the price, the method we'd use and anything that has to be fixed first, so you know what you're paying for before work starts.
We seal, then we insulate
Our crew handles the prep and sealing first and the insulation after, because filling a wall that still leaks air wastes part of what you paid for. I'm on site checking the work as it goes.
We walk through it together
Before we leave, I go over the finished work with you, with the holes plugged and the siding or drywall back in place. That's the time to ask me anything about what we did.
Why Yakima homeowners call C&D Yakima Insulation Solutions for their walls
I write every estimate myself
I come out to look at each job and write the estimate, and I'm on site checking the work while our crew installs. The person who told you what your walls need is the same one making sure it gets done.
A framer who switched trades
I spent years as a framing carpenter before starting this business in 2017, so when I open a wall I can see how the house went together and where air and water get in. That's why we fix those spots first instead of packing insulation around them.
Licensed and insured in Washington
Washington's Department of Labor & Industries, L&I, requires construction contractors to register with the state, and we're licensed and insured. The questions below show how to look up any contractor before you sign.
On a wall job, what counts is that every cavity ends up full, and that only happens when someone looks inside before quoting. Send us your details or call (509) 517-6081, and I'll set a time to come out.
Wall insulation, permits and older houses in Yakima
The City of Yakima issues some residential permits online without a plan review, but that list names re-siding and reroofing, not wall insulation, so it doesn't settle whether your wall job needs a permit. If it does, we take care of the application with the city or county office that covers your address, and if I'm not sure yet, I'll tell you that up front and find out. For permits outside the online list, the city asks for an application and construction plans showing the wall details, plus state energy code worksheets where they apply. If you'd rather ask the city yourself, you can email codes@yakimawa.gov or call (509) 575-6126.
Many of the houses we see around Yakima are older, and for homes built before 1978, L&I tells owners to call the Washington State Department of Commerce Lead Paint Program at 360-586-5323 before renovating or remodeling. Since we drill through painted surfaces, I bring that up at the estimate, and we run into the same older walls on jobs in Selah and Union Gap.
Questions about wall insulation in Yakima
How do you insulate walls without opening them up?
Installers blow insulation into each wall cavity through small holes drilled from the outside or the inside, then plug the holes, so the walls stay closed. It's the usual way to add insulation to a finished house, and it's how we handle closed walls, picking the side that suits your siding.
What does wall insulation cost per square foot in Yakima?
Across the US, installing blown-in wall insulation usually costs about $4 to $4.50 per square foot, and that's the general market figure, not a Yakima quote or ours. Your own price comes on a written estimate after I've seen the walls, and it moves with the things covered at the top of this page. Satisfaction guaranteed on every job.
Will foam on the outside trap moisture in my walls?
It can slow drying, because foam over the outside cuts how well the wall dries outward, so the wall needs to be able to dry toward the inside instead. In cold weather, warm, moist house air can get into a wall and condense on cold surfaces such as the sheathing, the boards right under your siding, and walls built to handle that keep mold and rot out. That's national building guidance, so if foam is part of a re-siding plan, ask your installer how the wall will dry, and I'll walk through it with you at the estimate.
How do I check a contractor in Washington?
Look the business up on L&I's Verify tool, which shows whether its contractor registration is active, whether its workers' comp account is paid up, and any safety violations or lawsuits against its bond. Washington requires construction contractors to register with L&I and to be bonded and insured, so a company that doesn't show up there is one to skip.
Does blown-in wall insulation settle over time?
It can if it goes in loose, and settled fill leaves empty pockets at the top of the wall where the cold gets through. National guidance says each cavity has to be filled completely and packed dense enough to resist settling, and at that density it also slows air moving inside the wall. Ask any installer how they make sure every cavity is full, and for us that's the packing method described above.
Do I have to leave the house while you insulate the walls?
Usually not for blown-in wall work, since we work through one section of wall at a time and the house doesn't need to be empty. Spray foam is different, because it comes with a re-entry time, how long before you and your pets can come back in, set by the foam maker's instructions. I'll tell you at the estimate which one applies to your job.
Work that pairs well with wall insulation
Air sealing services
Sealing gaps at outlets, top plates and pipes stops drafts that blow right through new insulation, so freshly filled walls hold the heat they're supposed to.
Basement insulation
If your floors stay cold after the walls are done, the basement walls and the framing on top of the foundation are often where heat still slips out.
