Select custom windows around light, use and fit
Compare fixed, casement, sliding and other operating styles against the way each room is used. Discuss privacy, ventilation, cleaning access and the desired view alongside frame material and finish. Large picture windows and grouped openings need dimensions and support confirmed before product orders are released.
Review the selected glazing and documented product ratings rather than assuming every custom window performs alike. Frame construction, glass options and orientation all matter to selection. Use available NFRC ratings to compare products; project-specific suitability and any applicable requirements still need confirmation.
Measure openings and coordinate weather protection
Distinguish an insert replacement within a serviceable existing frame from full-frame replacement or a changed rough opening. Identify what will be removed, how concealed damage will be assessed and which framing or structural questions need design input. Product dimensions should be confirmed through field measurements before procurement.
Define flashing, sill preparation, water drainage, air sealing and connections to the surrounding wall. Include interior trim, exterior finish repairs and protection of occupied rooms. An installation proposal should explain the complete opening treatment, not only the number of window units supplied.
Plan installation, selections and handover
Bring photographs, available plans and a room-by-room window list to the conversation. Confirm manufacturer, model, configuration, glass, finish and hardware in writing. Discuss delivery access, lead times and the sequence for temporary weather protection while existing openings are exposed.
Separate known installation work from allowances for concealed conditions and owner-requested changes. At completion, review operation, finish repairs, care guidance and the specific written product and installation warranty terms. Do not assume a quoted product rating guarantees a particular utility saving.
What to compare in a written proposal
- Window schedule with measured sizes and operating styles
- Named frame, glazing, finish and documented ratings
- Removal, flashing, sealing and finish-repair scope
- Room protection, lead times, change approvals and warranties
