A poorly insulated attic is the number one cause of high summer cooling bills. We bring your attic up to current performance standards with blown-in or spray foam material.

Blown-in insulation fills gaps and corners that rigid batts cannot reach, giving you a complete thermal barrier with no cold spots across your attic floor.

From attic to crawl space, we assess every area of your home and recommend the right insulation type for each location - no one-size-fits-all approach.

Old, wet, or pest-contaminated insulation has to come out before new material can perform. We remove it safely and prepare the space for a clean installation.

Cold floors in winter are a sign your crawl space is uninsulated. We seal and insulate below the floor, stopping cold air from pressing up into your living space.

Feel a draft near an outlet on a cold day? Wall insulation closes the gaps in your exterior wall cavities that let conditioned air escape and outdoor air in.

Insulation alone cannot stop air moving through cracks. We seal gaps around pipes, light fixtures, and penetrations so your insulation actually performs as rated.

An uninsulated basement lets cold and moisture into your living space. We insulate basement walls and rim joists to improve comfort and protect against moisture.

Closed-cell foam is the high-performance option for crawl spaces, exterior walls, and anywhere moisture is a concern - it insulates and acts as a vapor barrier.
Learn More
Open-cell foam is a flexible, cost-effective choice for attics and interior walls, and it dampens sound as a side benefit - a good fit for bedrooms near busy streets.

Air leaks at the attic floor are where most homes lose the most energy. We seal every gap before insulation goes in, so heat stays where you want it.
Learn More
Moisture rising from the soil through your crawl space damages insulation and framing over time. A vapor barrier stops that moisture before it causes problems.
Learn More
Proper vapor barrier installation protects crawl spaces, basements, and concrete slabs from moisture intrusion that leads to mold, rot, and structural damage.

Warehouses, offices, and commercial buildings lose energy through poorly insulated roofs and walls. We handle commercial insulation jobs of all sizes across the Tri-Cities.
Learn MoreReach out by phone or through the contact form. You will get a response within 1 business day. We ask a few simple questions about your home and what you have been noticing - high bills, uneven temperatures, cold floors. No pressure, no sales pitch.
A contractor visits your home and inspects the attic, crawl space, or walls - wherever the problem seems to be. They measure what is already there, check for air leaks, and look for moisture or pest issues. You get a written estimate that explains exactly what work is recommended and why.
On the day of the job, the crew arrives, does the work, and cleans up. Most residential jobs wrap in a single day. Before leaving, they walk you through everything that was done - so you can see it yourself and ask questions. You leave with documentation of the work.
We hold a current Washington State contractor license and carry full liability and workers' compensation insurance. Ask for our license number before work begins - you can verify it at lni.wa.gov in about 30 seconds.
Every estimate is free and comes with a written breakdown by area. You will know exactly what the job costs and why before you commit to anything. No surprise line items when the invoice arrives.
We live and work in the Tri-Cities. We know how Kennewick summers punish a poorly insulated attic and how cold crawl spaces get in January. That local context shapes every recommendation we make.
When you call or submit a request, someone from the office follows up within 1 business day to schedule your free estimate. If you are not hearing back that fast from another contractor, that is a useful data point.

"Our crawl space had never been insulated in 30 years. The crew came out, gave us a clear estimate, and had the job done in two days. Our floors were noticeably warmer by that first cold snap in November."
David R., Richland — Crawl space insulation
"Last summer our upstairs was 10 degrees hotter than the rest of the house. After the attic insulation and air sealing work, the difference was obvious within the first week. The August electric bill was the lowest we have had in years."
Maria T., Kennewick — Attic insulation
"We had spray foam done in the rim joists and crawl space before winter. They explained the difference between open-cell and closed-cell foam so I actually understood what I was getting. The process was exactly what they described."

Heat moves through your attic and into your living space when insulation is thin or air gaps are unsealed. In Kennewick, where summer highs top 100 degrees, an under-insulated attic forces your AC to run nearly constantly. Adding or upgrading attic insulation is the single highest-impact fix for homes that overheat in summer.
Spray foam and thorough air sealing close the gaps where outdoor air infiltrates your home. Once those gaps are sealed, your filtration system works as intended. The U.S. EPA notes that sealing air leaks can reduce the amount of fine particulates entering your home during poor air quality events - a real concern in the Tri-Cities.

Open-cell foam is softer and less expensive - it works well in attics and interior walls where moisture is not a concern. Closed-cell foam is denser and also acts as a vapor barrier, making it the right choice for crawl spaces and exterior walls. Most Kennewick homes benefit from closed-cell in the crawl space and open-cell or blown-in in the attic.
If existing insulation is water-damaged, pest-contaminated, or contains older degraded materials, adding new insulation on top will not perform correctly. Removal adds time and cost, but it is necessary in these cases. A reputable contractor will show you what they found and explain why removal is needed before asking for approval.
Peek into your attic with a flashlight. If you can see the tops of the wooden joists running across the attic floor, your insulation is too thin. For homes in Kennewick's climate zone, the Department of Energy recommends a finished depth of roughly 13 to 16 inches of blown-in material. The{' '} ENERGY STAR insulation guide at energystar.gov has a zip-code tool for exact recommendations.
Benton PUD, which serves much of Kennewick, has offered rebates for qualifying attic insulation upgrades. Pacific Power also serves parts of the area with similar programs. These change from year to year, so call your utility before scheduling work - a rebate of a few hundred dollars changes the math on a project you were already considering. Visit{' '} bentonpud.org to check current offerings.

Always before. Insulation slows heat movement, but gaps and cracks let air flow right past it. A contractor who seals first and insulates second will deliver noticeably better results than one who skips that step.
Wet or damp insulation loses most of its thermal performance and can grow mold. If a contractor finds moisture damage during an assessment, removal before new installation is not optional - it is necessary for the new material to perform correctly.
Blown-in insulation lasts 20 to 30 years with minimal maintenance. Properly installed spray foam can last the life of the home - often 50 years or more. Neither requires any action from you after installation.

Kennewick is the largest of the three cities that make up the Tri-Cities area in southeastern Washington, home to around 84,000 residents and a homeownership rate of about 60 percent. The city sits along the Columbia River in a high-desert environment that gets only 7 to 8 inches of rain per year - conditions that create specific wear patterns on local homes, from sun-baked siding to dusty air infiltration.
Kennewick has grown quickly since the 1980s, with much of the housing stock built between the 1970s and early 2000s. Neighborhoods like Southridge feature newer two-story homes, while older areas near Columbia Park and downtown include ranch-style homes from the 1970s and 1980s that were built to much lower insulation standards than what is recommended today. Downtown Kennewick is also home to the Toyota Center, the arena where the Tri-Cities Americans play and a well-known landmark in the city core.
The region's economy is anchored by the Hanford Site cleanup project and Pacific Northwest National Laboratory, bringing a stable base of long-term homeowners who invest in maintaining and improving their properties. Kennewick Insulation works on homes all across the city - from the older ranch homes near downtown to the newer subdivisions in west Kennewick - and understands what each part of town looks like and what those homes typically need.
