Quick answer
How this guide supports the calculators
Use this guide to clarify scope and comparison questions before opening the related calculators. The calculator pages own project-specific estimates; this guide owns the supporting planning method.
Normalize the scope before comparing totals
Start with one written homeowner baseline for size, materials, preparation, removal, approvals, access, cleanup, schedule, payment, and warranty. Copy each contractor's exact inclusions and exclusions into the same rows so a lower total is not mistaken for a lower price on the same work.
Treat blanks and allowances as open questions
A blank line, verbal promise, allowance, or optional alternate is not equivalent to included scope. Ask both bidders the same written clarification and preserve the answer with the original quote before selecting a contractor.
Compare the normalized decision, not the sticker price
Review the complete scope, missing items, payment milestones, warranty administration, schedule assumptions, and written change-order control. Only compare totals after the rows describe materially equivalent work.
Reusable template
Printable quote comparison worksheet
- Write one homeowner baseline before entering any bid: measured size, selected material or coating specification, removal, permits, access, cleanup, warranty, and target schedule.
- Copy each contractor's wording into the same row. Do not convert an allowance, alternate, or verbal promise into included scope unless the quote says it is included.
- Mark every blank or conflicting row as an open question and send the same clarification to both contractors in writing.
- Compare normalized scope, exclusions, payment terms, and change-order controls before comparing the final totals.
| Scope item | Homeowner baseline | Quote A | Quote B | Clarification |
|---|---|---|---|---|
| Measured project size | Area or linear feet | ________ | ________ | Are measurements and waste factors stated? |
| Material or product | Brand, line, grade, color | ________ | ________ | Are substitutions allowed and who approves them? |
| Preparation | Washing, excavation, base, scraping, priming | ________ | ________ | Which conditions trigger added prep? |
| Removal and disposal | Existing material and haul-away | ________ | ________ | Are dumping, concrete, or excess-weight fees included? |
| Labor and access | Crew scope, staging, difficult access | ________ | ________ | Is specialty access equipment included? |
| Permit and approvals | Permit, HOA, utility marking | ________ | ________ | Who applies, pays, and schedules inspections? |
| Site protection and cleanup | Landscaping, dust, daily cleanup | ________ | ________ | What is restored at completion? |
| Schedule | Start window, duration, weather delays | ________ | ________ | What can change the promised dates? |
| Payment terms | Deposit, milestones, retainage | ________ | ________ | Are payments tied to completed work? |
| Warranty | Labor and manufacturer coverage | ________ | ________ | Who handles a claim and what is excluded? |
| Exclusions and allowances | Known unknowns listed separately | ________ | ________ | Are allowances realistic and documented? |
| Change orders | Written approval before added work | ________ | ________ | Must price and schedule impact be approved first? |
Common omissions to verify
| Possible omission | Why it matters | Evidence to request |
|---|---|---|
| Delivery, freight, and minimum-order fees | A product allowance may omit the cost of getting materials to the site. | Delivery line item and minimum-order rule |
| Demolition and disposal | Removal can include hidden concrete, weight, or access charges. | Named materials, disposal volume, and haul-away limit |
| Permit, inspection, HOA, or utility marking | An approval delay or fee can change both price and schedule. | Responsible party, fee allowance, and inspection count |
| Surface or base preparation | Finish materials can fail when prep standards differ between bids. | Written prep sequence and condition threshold |
| Site protection | Landscaping, siding, windows, and access routes may need protection or repair. | Protection and restoration method |
| Hardware, fasteners, primer, or sundries | Vague supporting materials can hide a lower specification. | Product names, quantities, and substitution rule |
| Weather, access, and schedule assumptions | A short schedule may rely on conditions that are not guaranteed. | Delay rule and revised completion process |
| Warranty administration | A stated warranty is weak if responsibility and exclusions are unclear. | Written labor warranty and manufacturer claim path |
Change-order workflow
- Stop the affected work when a hidden condition or requested scope change is found; photograph and describe the condition.
- Request a written change order that states the added or removed scope, material specification, price, schedule impact, and warranty effect.
- Compare the change against the original worksheet and approved contingency rather than reviewing the new total in isolation.
- Approve or reject in writing before work continues, then attach the signed change to the quote, payment schedule, and final checklist.
Complete comparison examples
Example 1: 160-linear-foot wood privacy fence
Homeowner baseline: Six-foot wood privacy fence, one four-foot gate, old fence removal, ordinary access, post concrete, haul-away, and permit responsibility stated.
| Bid | Total | Included scope | Open items |
|---|---|---|---|
| Quote A | $8,950 | 160 linear feet; one gate; old panels and posts removed; permit allowance; two-year labor warranty | Post depth is not stated; Concrete disposal limit is not stated |
| Quote B | $8,420 | 160 linear feet; one gate; old panels removed; standard hardware | Old concrete footings excluded; Permit excluded; Post specification and warranty missing |
Normalized decision: Do not treat Quote B as $530 cheaper until it prices footing removal, permit responsibility, post specification, and warranty. If those additions exceed $530, Quote A is the lower normalized total.
Example 2: 1,800-square-foot exterior repaint
Homeowner baseline: Wash, scrape, spot-prime, caulk, two finish coats, siding and trim, landscaping protection, cleanup, and written lead-safe boundary for a pre-1978 home.
| Bid | Total | Included scope | Open items |
|---|---|---|---|
| Quote A | $7,200 | washing; scraping and spot primer; two finish coats; siding and trim; daily cleanup | Lead test is excluded; Rot repair uses an hourly allowance |
| Quote B | $6,450 | washing; one coat plus coverage coat if needed; siding; basic cleanup | Trim is an alternate; Primer rule is vague; No lead-safe process stated |
Normalized decision: Normalize Quote B by adding trim and a defined second-coat requirement. Both bidders must state how lead testing and any regulated work will be handled before price comparison or scheduling.
