Treat the opening as a system
Scope may include dimensions, existing frame condition, structural opening, sill and threshold, flashing,
water-resistive layers, siding or masonry interfaces, interior trim, hardware, egress, accessibility, security,
and water history. Product ratings and installation instructions must match the documented unit and
property.
What to share
Send property type and location, opening photos and approximate sizes, current window or door type,
leak or damage history, operation problems, desired product, exterior cladding, interior finish needs, and
whether the opening size will change. Include product documents when selected.
Can a unit be replaced without exterior work?
Sometimes. Existing frames, flashing, water paths, cladding, opening condition, product dimensions, and
installation method determine how much surrounding work is needed.
Share the openings, visible condition, product direction, water history, and surrounding exterior interface.
