Service Area
General contractor in Kenmore, WA
Kenmore sits at the north tip of Lake Washington, where many homes date from the 1970s and 1980s. Older ramblers and split-levels here often need roof, window, and kitchen or bath updates, and lakeside lots add moisture exposure. Masis Contractor LLC handles whole-home renovation, roof repair and replacement, and basement finishing for these homes.

Renovation Planning for Kenmore's Mid-Century Homes
Many Kenmore houses were built between the 1960s and 1980s, so original roofing, siding, and windows often reach the end of their service life. Our roof inspections and replacements target the moisture damage common near Lake Washington and the Sammamish River corridor.
Kenmore allows one accessory dwelling unit per lot, and the size limit depends on lot area. Lots over 6,000 square feet allow a detached unit up to 1,500 square feet, while smaller lots cap at 600 square feet. We check your lot size before design so the DADU plan fits the city's rules.
Basement finishing in older Kenmore homes often means working around original foundations and aging mechanical systems. We review the existing structure and moisture conditions first, then plan the finished space around them.

FAQ
General Contractor FAQ for Kenmore, WA
Common questions from Kenmore, WA customers about our services, process, and coverage.
Kenmore caps detached units at 10% of lot area, up to 1,500 square feet, on lots over 6,000 square feet. Lots under 6,000 square feet are limited to 600 square feet.
The city's guidance says no additional off-street parking space is required for an ADU. Confirm current requirements during your permit review.
Homes near Lake Washington, the Sammamish River, and creeks face persistent moisture, which speeds moss growth, wood rot, and roofing wear. Many houses from the 1970s and 1980s now need full roof replacement.
