Contractor Quote Worksheet for Whole House Plumbing Repiping
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 whole house plumbing repiping 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 65% 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 35% 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 3-7 days. Ask what happens if materials arrive late or hidden conditions are discovered. | A fast verbal timeline without milestones is hard to enforce. |
