Local Knowledge

About Mountlake Terrace Homes

What we see working in Mountlake Terrace neighborhoods and why it matters for your home.

Housing Stock

Mountlake Terrace was largely developed in the 1950s and 1960s, with ramblers and split-levels forming the backbone of neighborhoods like Melody Hill, Lakeview, and the areas west of 56th Avenue. Many of these homes retain their original insulation, which has settled well below the current R-49 code. The 1970s brought split-level homes along the eastern side of the city, and recent years have added townhomes and mixed-use development near the Town Center and Mountlake Terrace light rail station.

Common Home Issues

The mild, wet Puget Sound climate makes crawl space moisture a year-round concern in Mountlake Terrace. Homes near Lake Ballinger and in the lower-lying areas west of I-5 are particularly susceptible to standing water, failed vapor barriers, and mold growth. Older ramblers throughout the city also deal with rodent intrusion through deteriorated foundation vents and gaps in the crawl space access. These are common, solvable problems that we address regularly.

Neighborhood Character

Mountlake Terrace is a family-oriented city anchored by the Recreation Pavilion, Ballinger Park, and a well-used trail system that connects neighborhoods across the city. The new light rail station has brought renewed investment to the Town Center area, while the residential streets retain a quiet, established feel. Lake Ballinger provides a scenic centerpiece on the southern border, and local events like the Tour de Terrace festival reflect the community's strong neighborhood identity.

Frequently Asked Questions About Mountlake Terrace

Common questions from Mountlake Terrace homeowners about our services, scheduling, and what to expect.

Do you provide insulation and crawl space services in Mountlake Terrace?

Yes. Our north office is located right here in Mountlake Terrace at 6100 219th St SW Ste. 480. We provide insulation, crawl space repair, mold remediation, rodent proofing, sump pump installation, and general contracting throughout the city.

What insulation problems are common in Mountlake Terrace homes?

Many Mountlake Terrace homes were built in the 1950s and 1960s with insulation that falls well below the current R-49 code. Over the decades, blown-in attic insulation settles and compresses, and crawl space insulation sags or falls from contact with moisture and rodent activity. Homes near Lake Ballinger and in the lower-lying areas west of I-5 are especially prone to crawl space moisture problems.

What utility rebates are available for Mountlake Terrace homeowners?

Mountlake Terrace is served by Snohomish PUD, which offers rebates for qualifying insulation upgrades and weatherization improvements. We can help you understand what work qualifies and provide the documentation your utility needs for rebate processing.

How do I schedule a free estimate in Mountlake Terrace?

Call us at (800) 931-1938 or fill out the form on our website to schedule a free on-site inspection. Since our office is right in Mountlake Terrace, we can usually schedule estimates quickly. We will assess your home, explain what we find, and provide a written estimate with clear pricing.

Are newer homes near the Town Center and light rail station also at risk?

Newer construction generally has better insulation, but crawl space moisture and rodent intrusion are not limited to older homes. We regularly work on homes built in the 2000s and 2010s near the Town Center that need vapor barrier replacement, rodent exclusion, or attic insulation top-ups. A free inspection is the best way to know what your home needs.

Do you handle mold remediation in Mountlake Terrace crawl spaces?

Yes. Mold in crawl spaces is common in Mountlake Terrace, especially in older homes with inadequate vapor barriers or drainage. We remove the mold, address the moisture source, install new vapor barriers, and restore the crawl space to a clean, dry condition. We hold WA contractor license GREENAL785CS and are fully insured.
