Contractor Quote Worksheet for Interior Door Replacement
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 interior door replacement 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 45% 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 55% 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 whether your city treats this as permit-exempt or requires a trade, zoning, or HOA approval. | Permit gaps can delay final payment, insurance claims, or home resale. |
| Timeline and disruption | The normal timeline is 2-4 hours. Ask what happens if materials arrive late or hidden conditions are discovered. | A fast verbal timeline without milestones is hard to enforce. |

Interior Door Replacement Slab, Pre-Hung, and Finish Audit
Interior door prices change quickly depending on whether the job is a slab swap, pre-hung replacement, casing change, hardware upgrade, paint, or sound-control upgrade. Make every bid specify the door type and finish labor.
Scope checks
- 1Confirm the number of doors, slab vs pre-hung scope, hollow-core vs solid-core material, jamb condition, casing, hinges, bore, latch, knobs, stops, and paint or stain.
- 2Ask how the contractor handles out-of-square openings, trimming, floor clearance, carpet transitions, hinge alignment, strike plate adjustment, and old door disposal.
- 3For older homes, ask whether disturbing painted trim triggers lead-safe work practices and whether dust containment is included.
Quote traps
- A per-door price that excludes painting, casing repair, hardware, disposal, or jamb correction.
- Ordering slabs without measuring hinge locations, bore spacing, swing direction, and door thickness.
- Replacing bedroom or office doors with glass or hollow-core products that do not match privacy or sound expectations.
Proof to collect
- ✓Door count, swing, size, material, core type, hardware finish, and paint/stain scope in writing.
- ✓Photos of damaged jambs or trim before change orders are approved.
- ✓Final walkthrough checking reveal gaps, latch fit, rubbing, paint finish, and door stops.
What Affects the Price
- 1Number of doors
- 2Hollow vs solid core
- 3Pre-hung vs slab only
- 4Hardware
- 5Painting or staining
Popular Upgrades
- Solid core 1-3/8" doors
- Barn door hardware
- French doors
Discuss upgrades with your contractor before finalizing the quote. Some upgrades are cheaper to include during initial construction than to add later.
