Local Knowledge
About SeaTac Homes
What we see working in SeaTac neighborhoods and why it matters for your home.
Housing Stock
Most residential areas in SeaTac were developed in the 1960s and 1970s when the airport and surrounding commercial activity drove population growth. The neighborhoods along South 188th Street, around Angle Lake, and east of International Boulevard are filled with single-story ramblers and split-levels. These homes typically have original fiberglass batt insulation installed to standards far below today's R-49 code. Some homes near the airport also received window and wall insulation through Port of Seattle noise programs, but attic and crawl space conditions were generally not addressed.
Common Home Issues
SeaTac homes face the same Puget Sound moisture challenges as the rest of South King County. Crawl spaces commonly have thin or deteriorated vapor barriers, and many older homes have no barrier at all. Rodent activity is a frequent problem in the residential areas near Angle Lake and along International Boulevard, where nearby commercial density provides food sources that draw rats and mice into surrounding homes. Proper exclusion work, contaminated insulation removal, and re-insulation are the standard solution we provide.
Neighborhood Character
SeaTac is a compact city shaped by its proximity to Seattle-Tacoma International Airport. Despite the commercial activity along International Boulevard, the residential neighborhoods are quiet and well-established. Angle Lake Park provides a popular community gathering spot with swimming, walking trails, and light rail access. The city's diverse population supports a wide range of small businesses and restaurants along the main corridors. Most residential streets are set back from the airport noise zone and feel more suburban than the commercial strips suggest.
Why We Work Here
SeaTac is a natural part of our South King County service area, sitting between our Kent headquarters and our projects in Tukwila and Burien. The concentrated housing stock from the 1960s and 1970s means most homes in the city are at a similar stage of life, and many are overdue for insulation and crawl space upgrades. We have completed projects throughout SeaTac's residential neighborhoods and are familiar with the building styles, soil conditions, and common problems that homeowners here face.
Frequently Asked Questions About SeaTac
Common questions from SeaTac homeowners about our services, scheduling, and what to expect.
Do you provide insulation services in SeaTac, WA?
Yes. Green Attic serves SeaTac from our Kent headquarters, which is about 8 miles south. We provide insulation installation, crawl space repair, mold remediation, rodent proofing, sump pump installation, and general contracting throughout SeaTac. Our license number is GREENAL785CS.
What insulation and crawl space problems are common in SeaTac homes?
Most SeaTac homes were built in the 1960s and 1970s as single-story ramblers or split-levels with fiberglass batt insulation that was installed to much lower standards than today. After 50-plus years, that insulation has compressed, sagged, or been contaminated by rodents and moisture. Crawl spaces in the residential neighborhoods near Angle Lake and along South 188th Street commonly lack proper vapor barriers, leading to persistent dampness and mold conditions.
Are there utility rebates available for SeaTac homeowners who upgrade insulation?
Yes. SeaTac homeowners are served by Puget Sound Energy, which offers rebates for qualifying attic and floor insulation upgrades. The rebate amount varies by project scope and insulation type. We can explain what qualifies and help you through the rebate process during your free estimate.
How do I schedule a free estimate in SeaTac?
Call us at (800) 931-1938 or fill out the estimate request form on our website. Our Kent office is a short drive from SeaTac, so we can typically schedule your inspection within a few days. We assess your attic, crawl space, or both, document everything with photos, and give you a written estimate before any work begins.
How far is Green Attic from SeaTac?
Our Kent headquarters is approximately 8 miles south of central SeaTac, usually about a 15-minute drive. We work in SeaTac regularly and consider it part of our core South King County service area.
Does airport noise insulation overlap with energy insulation in SeaTac?
The Port of Seattle has run noise insulation programs for homes in the airport flight path, which typically address windows and some wall insulation. However, those programs do not usually cover attic insulation to current R-49 energy code or address crawl space conditions. Many SeaTac homeowners who received noise insulation upgrades still have underperforming attic insulation and crawl spaces that need vapor barriers, drainage, or mold remediation.
