Homeowners shopping a remodel collect 3 bids and call the cheapest one. Sometimes. The other times, they call the one that made them feel safest: the contractor whose estimate explained what was included, what wasn’t, and what would happen if something changed. A good contractor estimate template is the difference between winning the job at $42,000 and losing it to a guy at $38,500 who’ll change-order them to $54,000 by month two.
Your estimate isn’t a price. It’s an argument that you’ll finish the project on budget, on time, and without nightmare paperwork. Build it that way.
The one-page scope summary
Page one of any contractor estimate should be a plain-language summary of the job. Not phase breakdowns. Not line items. A paragraph the homeowner can read out loud to their spouse.
Full bathroom remodel at 142 Oak St. Demo existing tub/tile/vanity/flooring. Reframe shower wall to expand by 18 inches. New plumbing rough-in for shower valve and relocated vanity. Drain reroute for new vanity location. Electrical: 4 new can lights, GFCI outlet at vanity, exhaust fan upgrade. New tile (allowance), new vanity (allowance), new shower glass (allowance). All work to current code with permits pulled.
That paragraph wins more jobs than a 12-page line-item breakdown. The homeowner now knows you understood the project.
Phase breakdown with phase totals
After the summary, break out the phases:
| Phase | Includes | Phase total |
|---|---|---|
| Demo & disposal | Remove tub, tile, vanity, flooring; haul to dump | $1,850 |
| Framing | Move shower wall 18”, reframe niche | $1,400 |
| Plumbing rough-in | New valve, drain reroute, vanity supply | $3,200 |
| Electrical | 4 cans, GFCI, fan upgrade, permit | $2,100 |
| Drywall & paint | Hang, tape, prime, paint | $1,950 |
| Tile install | Floor + shower walls (material allowance separate) | $4,800 |
| Finishes install | Vanity, glass, fixtures, hardware | $2,400 |
| PM, supervision, permits | Coordination, inspections, project management | $3,200 |
Total labor & build: $20,900. Plus allowances (next section).
The phase total approach gives the homeowner clarity without exposing your hour-by-hour estimate.
Allowances done right
For every item the client hasn’t selected, name an allowance.
- Tile (floor + walls): $8/sq ft including grout, supplied = 145 sq ft = $1,160
- Vanity (single sink, 36”): $1,400
- Faucet, shower valve trim, accessories: $950
- Shower glass enclosure: $1,800
- Lighting fixtures (4 cans + vanity sconce): $650
- Flooring transition + baseboard: $300
Total allowance: $6,260
Then the clause:
Selections above allowance are billed at cost plus 15%. Selections below allowance credited at cost. Allowance items must be selected by [date] to maintain schedule. Schedule delays caused by late selections are not the contractor’s responsibility.
Now the homeowner owns the selection process and its consequences.
Exclusions: the most important page
Every contractor estimate needs a clearly labeled “Not Included” section. After twenty years on jobsites I’d argue this is the single page that decides whether the homeowner ends the project liking you or filing a complaint.
- Asbestos abatement or hazardous material remediation
- Mold remediation if discovered behind walls or under flooring
- Structural repairs to subfloor, joists, or framing not visible during estimate
- Plumbing repairs to lines beyond rough-in scope (galvanized replacement, etc.)
- Electrical panel upgrades or service changes
- Window replacements
- Cabinetry beyond vanity
- Appliances of any kind
- Painting outside the bathroom
- HOA approvals or permit expediting fees
- Cleaning beyond final broom-clean
Homeowners assume things are included. The exclusions section is your one chance to correct that assumption before the contract is signed.
Site assumptions
State what you assumed about the site. If those assumptions are wrong, the estimate isn’t.
- Existing framing is plumb and structurally sound
- Existing electrical panel has capacity for new circuits without upgrade
- Existing plumbing is copper or PEX (not galvanized)
- Subfloor is in usable condition under existing flooring
- No asbestos or lead present
- Access via standard doorways; no crane or specialty equipment required
If demo reveals otherwise, that’s a change order, not a contractor’s loss.
Timeline with start and substantial completion
Two dates. Vague timelines are how relationships die.
- Anticipated start: June 16, 2026
- Anticipated substantial completion: July 18, 2026
- Total active work days: 18 to 22 (excluding inspection delays beyond contractor control)
Define substantial completion in the contract: “the point at which the work is sufficiently complete for the intended use, with minor punch list items remaining.”
Payment schedule tied to milestones
For a $27,000 bathroom remodel:
- Signing deposit: $2,700 (10%, complies with state cap)
- Start of demo: $5,500
- Rough-in complete & inspected: $6,500
- Tile complete: $6,500
- Substantial completion (less punch list holdback of $800): $5,000
- Final on punch completion: $800
Each draw is tied to a verifiable milestone. Not the calendar, not “halfway through the month.” A milestone the homeowner can walk in and see.
The change order paragraph
All changes to the scope require a written change order signed by both parties before related work begins. Change orders include materials, labor, and 15% overhead and profit. Verbal change requests will not be honored. Change orders may affect schedule; revised completion dates will be stated on the change order.
Hand the homeowner a change order form template in your contractor estimate. Show them you mean it.
Warranty and final paragraph
State your warranty plainly.
Workmanship warrantied for 1 year from substantial completion. Manufacturer warranties on materials and fixtures pass through to homeowner. Warranty void on items damaged by misuse, third-party work, or normal wear.
Send the estimate within 5 business days
Three bids, three estimates. The first one that arrives sets the comparison anchor. More importantly, it shows up while the homeowner still remembers your face from the walkthrough.
Use a tracked estimate that tells you when the homeowner opened it and which pages they spent time on. If they re-read the allowances page on day 6, call them: they’re choosing finishes mentally. If they re-read the payment schedule, the budget is the issue. The follow-up that addresses the actual concern wins the job.
