Pre-Work Checklist (Design, Materials, Access)

The best bids come from consistent inputs. Also, If you give three contractors three different descriptions, you’ll get three different prices—and none will be truly comparable.

Use the checklist below to prepare your scope and make the proposal stage faster and cleaner.

Design And Materials Checklist (Make Choices That Affect Pricing)

  • Window style: sliding, single-hung, double-hung, casement, awning, fixed.
  • Frame material: vinyl, fiberglass, aluminum, wood/clad (each affects cost and maintenance).
  • Glass needs: privacy, noise reduction, safety glass near wet areas, tint level, and Low-E preferences.
  • Grids/screens/hardware: keep finishes consistent so bids cover the same options.
  • Interior trim plan: keep existing trim, replace with new, or convert to a different profile.
  • Exterior finish plan: clarify whether the bid includes patching/painting where needed.

Have the contractor verify each opening size and condition before the window order is placed. For this reason, That single step prevents delays and “it doesn’t fit” surprises.

Access And Site Protection Checklist

  • Confirm where materials will be staged and where the crew will park/load in Los Angeles.
  • Move fragile items, clear window areas, and plan for pets/children during work hours.
  • Decide how you want dust control handled (barriers, vent protection, daily vacuuming).
  • Plan for window coverings and security while work is active (especially ground-floor openings).
  • Identify any HOA/landlord approval steps early if applicable to your property.

Small-Space Window Planning (Kitchens And Bathrooms)

Window replacement is still a contractor-selection job, but small rooms deserve extra attention because one wrong opening direction can create daily annoyance.

  • Over sinks/counters: awning or casement windows can clear faucets and backsplashes better than some slider layouts.
  • Bathrooms: prioritize privacy glass and easy-to-clean frames; ask about safety-glass needs for your specific opening.
  • Ventilation: if the window is the only natural vent, confirm operation is easy and the opening meets your comfort goals.
  • Clearances: check that new locks/handles won’t hit cabinets, mirrors, or shower enclosures.

Mistakes That Drive Change Orders (Avoid These)

  • Accepting a “per window” price with no written spec sheet or window-by-window locations.
  • Comparing bids that mix retrofit and full-frame methods without calling it out.
  • Skipping discussions about trim, drywall, paint prep, and exterior patching until install day.
  • Choosing specialty glass or colors late in the process, which can extend ordering lead times.
  • Not discussing lead-safe work practices if your home may have older paint; ask how the crew contains dust.
  • Letting a contractor start without a clear plan for permits/inspections when scope changes trigger them.
