Frequently Asked Questions
It depends on scope. A like-for-like swap may be treated differently than changing an opening size, adding a new window, or touching structural framing. Because requirements can vary by address, ask your contractor to outline the permit plan in writing, and confirm details through the City of Berkeley Permit Service Center when needed.
- Ask who will submit the permit (if required) and who will schedule inspections
- Confirm whether any safety glazing or emergency escape opening rules apply to your locations
- Build review/inspection time into your schedule when your scope changes openings
A good bid is specific enough that you can compare contractors without guessing. If the proposal is vague, push for details before you sign.
- Window type and approach (retrofit insert vs full-frame)
- Brand/line, glass features, and hardware details
- Interior and exterior finish work included (trim, drywall, paint, stucco/siding)
- Protection plan for floors, furniture, and openings
- Cleanup, haul-away, and warranty terms
Neither option is automatically better. Retrofit inserts can be faster and less disruptive when the existing frame is in good condition. Full-frame replacement can make sense when you need to address damaged frames, water issues, or you want to change the opening details.
Ask the contractor to explain the condition of the existing frames and how each option affects finish work and long-term maintenance.
Many projects complete installation in a small number of days, but the timeline depends on how many windows you replace, whether you need repairs, and whether permits apply. In addition, ordering lead times often drive the calendar more than the install days.
Ask for a milestone-based schedule: ordering, delivery, install days, and a punch list/walkthrough date.
Often, yes. The key is choosing a window style that fits the space and keeps finish work minimal. For example, a slider can avoid conflicts over a kitchen sink, while an awning window can add ventilation in a small bathroom.
During the estimate, point out tile edges, cabinets, and any moisture concerns so the scope includes the right protection and finish details.
