Contractor Quote Worksheet for Water Heater 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 water heater 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 35% 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 65% 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 1 day. Ask what happens if materials arrive late or hidden conditions are discovered. | A fast verbal timeline without milestones is hard to enforce. |

Scope Audit Before You Hire
A useful contractor bid should define the work clearly enough that two companies are pricing the same job. Use this audit to catch missing details before the project turns into change orders.
Scope checks
- 1Confirm measurements, material grade, prep work, disposal, cleanup, warranty, and the exact finish level.
- 2Ask whether permits, inspections, HOA approvals, utility coordination, or specialty trades are included.
- 3Document hidden-condition assumptions such as rot, moisture, structural repair, old wiring, or access limitations.
Quote traps
- A single lump-sum price with no allowance detail.
- A quote that excludes demolition, hauling, patching, cleanup, or return visits.
- A low deposit offer without license, insurance, references, and a written change-order process.
Proof to collect
- ✓Itemized bid with material quantities and model numbers where relevant.
- ✓Before and after photos for concealed work.
- ✓Final invoice, permit closeout if required, and written warranty.
