Climate and energy performance in Fairfax
Fairfax city sees about 43.6 inches of precipitation and 18.5 inches of snow in a normal year.
Weather at that level is one more reason the flashing and sill pan under a Fairfax window matter as much as the glass sitting in it.
So ask any Fairfax contractor how they handle both, not just which brand they carry.

Ranked by Google rating weighted against how many people left one, so a perfect score from a handful of reviewers never outranks a strong average built on hundreds. That ranking is not a license check; call the state directly and ask for the contractor's license or registration number.

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?
