Yakima houses we insulate, old and new
Yakima is where we're based, and it's where I started this business in 2017 after years of framing houses, so I tend to read a house by how it was put together. On jobs around the city we get into older homes with low, tight attics and crawl spaces under the floors, ranch houses from later decades, newer houses with a room over the garage, and plenty of rentals that landlords want comfortable for their tenants. We do the same work in Selah and Union Gap, along with the other cities around Yakima.
The age of the house decides most of the job. An older one usually needs gaps sealed, old material cleared and sometimes wiring looked at before anything new goes in, while a newer one is more often just thin at the edges or missing insulation over the garage.
Insulation services we do across Yakima
Spray foam insulation
When ductwork runs through the attic or the room over the garage stays hot, spray foam seals the air and insulates in one pass, at a higher cost.
Attic insulation
Most of our calls start in the attic, where we check the inches already up there, fix what comes first and fill evenly out to the edges.
Blown-in insulation
Blown-in, loose fill blown through a hose, is usually how we top up a thin attic once the gaps are sealed, with the eave vents kept clear.
Home insulation
For a drafty house with cold rooms and a high power bill, we look at attic, walls and crawl space together and say what comes first.
Insulation removal
When old insulation is soaked, flattened or full of droppings, we pull it out first, because new material laid over it keeps the problem in the attic.
Crawl space insulation
Cold floors over a crawl space are a common complaint in older Yakima houses, and we insulate the floor or walls down there once it's dry.
Wall insulation
Some older houses here have walls with little or nothing in them, and we can usually fill closed walls without tearing off siding or plaster.
Air sealing services
Air sealing, closing the gaps before insulating, stops the drafts that sneak around pipes, wires and old chimneys so the insulation isn't fighting moving air.
Basement insulation
Where a Yakima house has a basement, heat slips out through bare concrete walls and the rim where the house sits on the foundation, so we insulate both.
Closed-cell foam insulation
Closed-cell foam, dense foam that blocks moisture, suits damp spots like a crawl space rim or a basement wall, once the water source is fixed.
Open-cell foam insulation
Open-cell foam is softer and lighter, and it suits a roof deck or wall where you want air sealed and sound quieted but moisture isn't the worry.
Commercial insulation
Property managers call us for shops, offices and small commercial buildings around Yakima, and we plan the work around tenants and business hours.
Crawl space vapor barrier
A plastic vapor barrier over a bare dirt crawl space floor keeps ground moisture out of the framing and the insulation above it.
Vapor barrier installation
In walls and ceilings that are already open, we add a vapor barrier where the job calls for one, so moisture stays out of the insulation.
Attic air sealing
Before any insulation goes up, we seal around can lights, the attic hatch, plumbing stacks and wire holes, because those gaps are where warm air leaks out.
Retrofit insulation
Retrofit work adds insulation to a house that's already lived in, the usual job in Yakima's older neighborhoods, and we cover and clean the rooms we work through.

Working in Yakima: permits, licenses and what sets the price
Building permits inside Yakima city limits come from the City of Yakima's Code Administration Division, and that's who we ask when a job might need one. The city's list of simple online permits names things like reroofs, re-siding and same-for-same change-outs, not insulation, so if we're not sure about your job we tell you up front, find out from the city and handle the application, and our crew doesn't start until any permit is issued. When you're choosing a contractor, check that they're registered with the Washington State Department of Labor & Industries, which requires a $15,000 bond for specialty contractors or $30,000 for general contractors, plus liability insurance of $200,000 for public liability and $50,000 for property damage, or a $250,000 combined limit. The city also requires a business license for every business working inside city limits. We're licensed and insured, and I'm glad to answer any of that on the first call.
What moves the price is mostly what's already in your house: how many inches are up there now, whether old insulation has to come out first, how many gaps need sealing and how hard the attic or crawl space is to get into. The schedule turns on the same things, plus any repair that has to come first, like a roof leak, a damp crawl space or wiring an electrician needs to see. I put all of it on a written estimate after I've looked, so the number you get is for your house and not a guess. We work the same way just east of the city in Terrace Heights and in the other cities around Yakima.
Why Yakima homes end up drafty and uneven
A lot of the houses we get into here were insulated once, years ago, and never touched again. The old material has settled, mice have been through it, and someone added a can light or a bathroom fan without sealing the hole, so warm air rides straight up past the insulation. What looks like an insulation problem is usually an air problem first, which is why we seal before we add anything and keep the eave vents open so the attic can still breathe.
Under the floor is the other half. The city designs foundations for frost reaching 24 inches below grade, so the ground under a house gets properly cold, and cold floors over a crawl space are what we hear about most after the attic. We make sure it's dry, lay a vapor barrier where the dirt is bare, then insulate.
How a job runs when you call us in Yakima
Here's how a job goes from your first call to the walk-through, so you know who'll be at your door and what happens at each step.
Call or send the form
We call you back to set a time for me to come look at the house. It helps if you're home for that visit so you can show me the rooms that bother you.
I look and write it up
I go into the attic, crawl space or walls myself, show you what I find and write down the price, so you know the cost before you agree to anything. If a leak, a damp spot or old wiring has to be dealt with first, I'll tell you plainly.
Prep and sealing, then insulation
Our crew clears out what has to go and seals the gaps before any new insulation goes in, and I'm on site checking the work as it goes. If the city requires a permit for your job, it's issued before this step starts.
Walk through the finished work
Before we leave, I go over the finished attic or crawl space with you and show you the depth and the sealed spots. Satisfaction guaranteed on every job.
Questions about insulation in Yakima
How much does attic insulation cost in Yakima?
The cost comes from what's already in your attic and what has to happen before new insulation goes in, so I give you a written number after I've looked rather than over the phone. Topping up loose fill in a clean attic costs the least, and pulling out soaked or droppings-filled material adds to it. Foam costs more because it seals and insulates at once, and I usually only recommend it when the ductwork runs through the attic, because otherwise sealing the gaps and topping up blown-in does the job for less.
Which building codes apply to insulation work in Yakima, WA?
Yakima currently works from the 2021 Washington State codes, including the residential and existing building codes, and the state's 2024 codes take effect May 3, 2027. We do the work to the codes in effect when your job is done, and when a permit is involved the city reviews it against them.
Who handles the electrical permit if you find old wiring in my Yakima attic?
Whoever does the electrical work gets the permit and the inspection, and in Yakima those go through the state's L&I office at (509) 454-3760, not the city. We're insulation people, not electricians, so if I find old or damaged wiring I stop, show it to you, and an electrician deals with it before we cover anything up.
Do we have to leave the house during spray foam insulation in Yakima?
Yes, for spray foam you, your kids and your pets stay out for the re-entry time, the hours the foam maker says to wait before anyone comes back in. I tell you that wait at the estimate, based on the product we'll use. With blown-in in the attic, most families stay home and just keep kids and pets away from the hatch.
How long does it take to insulate an attic in Yakima?
Usually less time than people expect, because blowing in the insulation goes quickly and most of the job is prep. Removing old material and sealing around lights, pipes and the hatch take longer, and a cramped, low attic slows everything down. I'll tell you how long our crew will be at your house when I write the estimate.
What causes the room over my garage in Yakima to stay hot or cold?
Usually it's thin insulation and open gaps in the floor and outside walls of that room, so garage air moves right under your feet. We seal those gaps and fill the floor and the kneewalls, the short walls under the sloped ceiling, so the room holds its temperature better.
