What Shoreline's climate means for your window spec
King County sees about 37.8 inches of precipitation and 3.8 inches of snow in a normal year.
Weather at that level is one more reason the flashing and sill pan under a Shoreline window matter as much as the glass sitting in it.
So ask any Shoreline contractor how they handle both, not just which brand they carry.

Questions to ask before you sign
- How long have you held your state license, and can I see the number?
- Is this a full-frame replacement or an insert into my existing frame, and why that one?
- Who pulls the permit, and does this change trigger an egress check on a bedroom window?
- What flashing and sill pan will you use, and in what order do you install them?
- If my home was built before 1978, is your crew lead-safe certified for this job?
- What's the completion date in writing, and what happens if the schedule slips?
