Climate and energy performance in Aliso Viejo
Orange County sees about 12.7 inches of precipitation and 0.0 inches of snow in a normal year.
Weather at that level is one more reason the flashing and sill pan under a Aliso Viejo window matter as much as the glass sitting in it.
So ask any Aliso Viejo contractor how they handle both, not just which brand they carry.

Google's top window installers serving Aliso Viejo, CA
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.

- 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?
