Identify the designed outlets.
Ask the installer to point out the drainage features on the selected model. Do not assume that openings on a different window product serve the same purpose.
Windows · Renton, Washington
Window replacement in Renton should include an explanation of the selected unit’s drainage paths. Ask the installer where water leaves the frame and which openings must remain clear, rather than assuming every opening along a sill should be sealed.
Evergreen Home Pro helps you prepare that product-specific conversation. Share the existing sill and track condition and ask for the care instructions for the new unit.

Window replacement
Some window systems channel collected water through exterior weep openings. Have the installer distinguish designed drainage features from a defect, and explain when continued pooling or water reaching the interior needs assessment.
Ask the installer to point out the drainage features on the selected model. Do not assume that openings on a different window product serve the same purpose.
Have the installer explain how frame drainage relates to the surrounding opening and finish work. Caulk and trim should follow the actual system instructions rather than obstruct a designed outlet.
Request the model-specific cleaning guidance and ask what symptoms should trigger a service call. Avoid using a generic cleaning method or filling an opening before its purpose is confirmed.
Before work begins
Renton’s code describes an in-kind window exemption with opening, structural, energy, required safety-glass and bedroom or basement egress conditions. Have the complete selection assessed against those conditions.
An unchanged-looking frame does not by itself settle the exemption. Identify any opening or structural change and keep the required performance information with the actual window schedule.
Ask the installer to identify designed drainage openings and follow the selected product instructions.
Have persistent pooling or interior leakage assessed in the context of that window’s design.
No. Renton also identifies structural, energy, safety-glass and applicable egress conditions.
