Contractor Quote Worksheet for Egress Window Installation
Use this checklist when comparing bids. The cheapest quote is not always the lowest final cost; the bid that defines scope, allowances, permits, cleanup, and change-order rules usually gives the cleaner budget.
| Bid line | What to ask | Why it matters |
|---|---|---|
| Scope definition | Confirm what is included in the egress window installation base bid and what is priced as an allowance or option. | Vague scope turns into change orders after demolition or material selection. |
| Labor assumptions | Labor is about 60% of the mid-range budget. Ask whether demo, prep, cleanup, disposal, and final punch-list time are included. | A low bid may exclude prep work, disposal, or return trips. |
| Material allowances | Materials are about 40% of the budget. Get brand, grade, finish, and quantity assumptions in writing. | Allowance bids look cheap until fixtures, finishes, or delivery fees are upgraded. |
| Permit and inspection plan | Confirm who pulls permits, who pays fees, and when inspections happen. | Permit gaps can delay final payment, insurance claims, or home resale. |
| Timeline and disruption | The normal timeline is 2-3 days. Ask what happens if materials arrive late or hidden conditions are discovered. | A fast verbal timeline without milestones is hard to enforce. |

Egress Window Code and Drainage Audit
An egress window is a life-safety project, not just a basement window. The quote should address code opening, excavation, drainage, foundation cutting, and final inspection.
Scope checks
- 1Confirm the local code edition, required clear opening, sill height, window well size, ladder or steps, and inspection plan.
- 2Ask how excavation, spoil removal, foundation cutting, lintel/header work, waterproofing, and drainage tie-in are handled.
- 3Require the bid to separate window, well, cover, drainage, concrete cutting, interior trim, and exterior restoration costs.
Quote traps
- A window that adds light but does not satisfy emergency escape requirements.
- No drainage plan for the well.
- Excluding interior finish repair, exterior grading, concrete dust control, or permit fees.
Proof to collect
- ✓Permit and final inspection closeout where required.
- ✓Photos of well drainage and waterproofing before backfill.
- ✓Manufacturer specs for the window, well, cover, and ladder or steps.
