Common Mistakes That Create Surprise Costs
- Comparing totals without matching the install method and finish scope
- Accepting a bid that doesn’t list window model numbers and glass specs
- Assuming trim/patching/paint are included when they are listed as exclusions
- Waiting to choose color, grids, or hardware until after ordering (that can reset lead time)
- Not planning for opening repairs and then feeling forced into on-the-spot decisions
- Letting change orders happen verbally instead of in writing
- Skipping a plan for protecting floors, furniture, and pets during installation
- Not clarifying who coordinates permits/inspections if the scope requires them
