What we see with window and trim repair in Mountlake Terrace
In Mountlake Terrace, where older ramblers sit close to grade, and additions tied into original walls often have flashing gaps, window and door openings are the most common entry point for water. With 1950s post-war ramblers, many with original wood siding and additions built later, many openings were built before sill pans were standard.
Many Mountlake Terrace homes have had additions, and the joint between old and new is where we usually find the leak. We regularly work in Lake Ballinger, Town Center, Terrace Creek and Cedar Way.
Mountlake Terrace is a compact city around Lake Ballinger and Terrace Creek, with tree-lined streets that keep many walls shaded. Post-war 1950s ramblers, many with additions built later, and newer townhomes near Town Center.

Windows, Doors & Trim in Mountlake Terrace: what you should know
Window and door openings are the most common place water gets into a wall. In Mountlake Terrace, we see rot start at the bottom corners of windows and at door thresholds, where water that gets in at the top runs down and collects. Trim is the visible part, but the fix almost always includes the flashing and framing behind it.
What causes it in Mountlake Terrace
No head flashing
Water running down the wall gets behind the top trim and into the opening.
No sill pan
Water inside the opening drains into the sill framing instead of out.
Flat or poorly sloped trim
Sills and head trim without slope hold water against the wood.
Door thresholds without pans
Doors to decks and patios leak at the bottom corners and rot the subfloor.
What our window and trim repair includes
- Removal of rotted trim, sills and brick mold
- Inspection and repair of jack studs, sills, headers and cripples
- Sloped sill pans and jamb flashing tape
- Head flashing over new trim
- Window or door re-set or replacement when needed
- New trim in PVC, fiber cement or primed wood
- Caulk, prime and paint to match
How to prevent it
- Repaint window trim before the paint fails
- Keep weep holes and window tracks clear
- Check the bottom corners of trim each fall
- Do not caulk the bottom edge of head flashing
- Replace failed glazing seals and weatherstripping
What affects the cost in Mountlake Terrace
Trim-only repairs are the least expensive. When the framing under the window is soft or the window has to come out to install a sill pan, the job grows. We check the sill and corners first and quote the trim and flashing separately from any framing.
How long it takes
Trim and flashing repair is usually a few hours to a day per opening. Openings with framing repair or window re-sets take one to two days each.
