Local Knowledge
About Kent Homes
What we see working in Kent neighborhoods and why it matters for your home.
Housing Stock
Kent is one of the largest cities in King County with housing spanning seven decades. The valley floor between West Hill and East Hill has ramblers and split-levels from the 1950s and 1960s, many still running on original fiberglass batt insulation. East Hill neighborhoods like Scenic Hill, Meridian, and the Kent-Kangley corridor filled in during the 1980s and 1990s with two-story homes that used blown-in insulation meeting the codes of that era. Newer construction east toward Covington from the 2000s is better insulated but still commonly uses builder-grade materials that settle within 15 to 20 years.
Common Home Issues
The Green River Valley's high water table creates persistent moisture challenges for valley-floor homes. Crawl spaces regularly develop standing water, condensation, and compromised vapor barriers. On East Hill, the most common problems are settled attic insulation, poor attic ventilation, and rodent intrusion through gaps around plumbing and utility penetrations. Across all neighborhoods, we frequently find insulation that has compressed below the R-49 code requirement, leading to higher heating bills and cold spots through the winter.
Neighborhood Character
Kent is anchored by the Kent Station shopping district downtown and stretches from the industrial corridor near the Green River Trail up through the residential neighborhoods of East Hill. Families in the Kent School District, parks along the Green River, and proximity to commuter routes on I-5 and SR-167 make it one of the most lived-in cities in South King County. Long-time homeowners on the valley floor and newer families on East Hill both invest in their homes, and insulation upgrades are one of the most impactful improvements for comfort and energy savings.
Why We Work Here
Green Attic is headquartered at 21814 84th Ave S in Kent because this is where our work is concentrated. We are in Kent homes every week, and our crew knows the area, the housing styles, and the problems that come with each. Being based locally means shorter drive times, faster scheduling, and familiarity with the specific insulation and crawl space challenges Kent homeowners face. It also means we stand behind our work in the community where we operate.
Frequently Asked Questions About Kent
Common questions from Kent homeowners about our services, scheduling, and what to expect.
Do you provide insulation services in Kent, WA?
Yes. Green Attic is headquartered in Kent at 21814 84th Ave S. We provide insulation installation, crawl space repair, mold remediation, rodent proofing, sump pump installation, and general contracting throughout Kent and South King County. Our license number is GREENAL785CS.
What insulation problems are common in Kent homes?
Kent homes on the valley floor, especially in older neighborhoods west of 104th Ave SE, often have original fiberglass batts from the 1950s and 1960s that have compressed and lost most of their R-value. East Hill homes built in the 1980s and 1990s commonly have blown-in insulation that has settled well below the current R-49 code requirement. Both situations lead to higher energy bills and uneven temperatures throughout the home.
Are there utility rebates available for Kent homeowners who upgrade insulation?
Yes. Most Kent homeowners are served by Puget Sound Energy, which offers rebates for qualifying attic and floor insulation upgrades. The exact rebate amount depends on the scope of the project and the insulation type installed. We help customers through the rebate process and can explain what qualifies during your free estimate.
How do I schedule a free insulation estimate in Kent?
Call us at (800) 931-1938 or fill out the estimate request form on our website. Since our office is right here in Kent, we can usually schedule your inspection within a few days. We will assess your attic, crawl space, or both, document what we find with photos, and provide a written estimate on the spot.
Why do so many Kent valley floor homes have crawl space moisture problems?
The Green River Valley has a naturally high water table, and the alluvial soil retains moisture year-round. Many older Kent homes along the valley floor between West Hill and East Hill were built without modern vapor barriers or drainage systems. This combination means standing water, elevated humidity, and condensation in crawl spaces, which leads to mold growth, wood rot, and pest activity if left unaddressed.
What sets Green Attic apart from other insulation contractors in Kent?
We are locally headquartered in Kent, not a franchise or a crew dispatched from out of the area. We hold a 4.9-star rating across 102 reviews, are licensed (GREENAL785CS) and insured, and we start every project with a thorough free inspection.
