Homes in Mountlake Terrace
Mountlake Terrace was built quickly after World War II as an affordable planned community, and its core is still made up of modest 1950s ramblers on regular grid lots. Most started as small single-story homes on crawlspaces or slabs, with cedar or plywood siding and simple gable roofs. Over the decades, owners added bedrooms, second stories, converted carports and back decks, so many houses now combine original walls with several generations of additions. Around Town Center and the light rail station, newer townhomes and apartment buildings are going up, while the Lake Ballinger area includes some larger and newer homes.
Mountlake Terrace sits on flat to gently rolling ground east of Edmonds, away from direct Sound exposure but within reach of the convergence zone showers that often settle over south Snohomish County. Rain falls steadily through fall and winter, and the low, flat terrain does not always drain quickly. Homes near Lake Ballinger and along creek corridors deal with a higher water table and occasional flooding. Ramblers built close to grade suffer from splashback, and additions tied into older walls create seams where water finds its way in.
Around Lake Ballinger, low ground and higher groundwater keep crawlspaces and lower walls damp. Near Town Center, older ramblers sit beside new construction, and changes in grading can redirect runoff toward neighboring lots. Terrace Creek Park and the streets around it are more wooded, keeping roofs and decks shaded. Along Cedar Way and the I-5 corridor, many homes have had multiple additions, and the seams between old and new walls are where leaks usually start.

Learn moreWhat we fix most in Mountlake Terrace homes
Deck Waterproofing & Flashing
Walkable waterproof coatings, slope fixes and flashing that keep water out of your walls and ceilings. In Mountlake Terrace, that usually means worn coatings and missing flashing let water into walls and ceilings.
Fascia & Soffit Repair
Rotted fascia, soffits and rafter tails replaced, with drip edge so the roof edge stays dry. In Mountlake Terrace, that usually means overflowing gutters soak the fascia and rafter tails at the roof edge.
Balcony & Porch Repair
Rotted balconies, porches, columns and railings rebuilt safely and waterproofed. In Mountlake Terrace, that usually means balconies, porches and columns take weather on every side and rot at the connections.
Every visit starts with a free inspection: we probe the wood, check moisture, photograph what we find and give you a written price before any work starts. Small in-kind repairs, like replacing a few boards or a section of trim, frequently need no permit. Structural work, new decks, additions and larger siding replacements usually do, and properties near Lake Ballinger or creek corridors may involve extra review. Our crew checks with the City of Mountlake Terrace up front and files for a permit whenever one applies.
