Homeowner planning checklist
Homeowner contractor quote checklist
Last reviewed July 8, 2026
Use this checklist before requesting HVAC, roofing, or EV charger quotes. It helps you prepare the details contractors need, compare written scopes, and understand why a final price may change after inspection.
Photos to take
- Current equipment, roof areas, charger location, or project area.
- Access points such as attic, crawlspace, garage, driveway, panel, or roof edge.
- Visible damage, leaks, code concerns, long wiring runs, or difficult work areas.
- Model numbers, labels, breaker panel details, material condition, or previous repair evidence.
Details to gather
- ZIP code, property type, ownership status, and project timeline.
- Home square footage, roof size estimate, system age, charger amperage, or panel size when known.
- Budget range, preferred materials/equipment, and whether you need repair, replacement, or installation.
- Any permit, HOA, utility, insurance, or access constraints you already know.
How to compare estimates
- Compare the written scope line by line, not just the total price.
- Check whether permit, inspection, cleanup, disposal, and warranty are included.
- Ask what assumptions could trigger a change order.
- Keep planning estimates separate from final contractor bids.
Contractor comparison
Questions to ask every contractor
- Is this a firm quote or a planning estimate?
- What assumptions are included and what is excluded?
- Is permit handling included?
- What conditions could increase the final price?
- What warranty applies to labor and materials?
- Who handles cleanup, disposal, and final inspection?
Quote warning signs
Review these before approving work
The quote does not say whether permit or inspection is included.
The contractor cannot explain what is excluded.
The quote uses a single total with no material, labor, warranty, cleanup, or change-order assumptions.
The bid depends on urgency pressure instead of written scope clarity.
Warranty terms, license/insurance details, or subcontracted work are unclear.
The scope ignores visible complexity such as old ducts, damaged decking, panel capacity, trenching, or access constraints.
Project-specific checklists
Prepare based on the project type
Project scope checklist
Classify the scope before you request quotes
- System size, home square footage, and comfort issues
- Ductwork condition and attic/crawlspace access
- Indoor and outdoor unit access constraints
- SEER2 or efficiency preference
- Thermostat, zoning, electrical, gas, or condensate scope
- Permit, inspection, warranty, and timeline assumptions
Quote readiness
What to prepare before contacting contractors
- Take clear photos of the current equipment or project area.
- Write down your timeline, budget range, and whether you are ready to hire.
- Collect model numbers, approximate age, measurements, or existing material details.
- Ask each contractor to separate required work from optional upgrades.
- Photograph indoor unit, outdoor unit, ducts, thermostat, and access areas.
- Ask whether ductwork, thermostat, electrical, gas, condensate, permit, and startup testing are included.
Project scope checklist
Classify the scope before you request quotes
- Approximate roof size or home square footage
- Roof pitch, number of stories, and access constraints
- Tear-off layers and whether old material must be removed
- Material choice: asphalt, architectural shingle, tile, metal, or flat roof
- Decking, underlayment, leak, or storm-damage concerns
- Permit, inspection, cleanup, disposal, and warranty assumptions

- Photograph leaks, damaged shingles, flashing, gutters, and attic signs of water.
- Ask whether decking, underlayment, ventilation, tear-off, and disposal are included.
Project scope checklist
Classify the scope before you request quotes
- Electrical panel capacity and available breaker space
- Distance from panel to charger location
- Garage, driveway, exterior wall, carport, or multifamily parking layout
- Desired amperage and plug-in versus hardwired charger
- Whether trenching, conduit, pedestal, or exterior routing is needed
- Permit, load calculation, utility, and incentive questions

Estimate limitations
When this estimate may be wrong
- Hidden damage or unsafe existing conditions can change the scope.
- Local permit or inspection requirements can vary by jurisdiction.
- Emergency scheduling or unusual access can raise labor cost.
- Final pricing requires inspection, measurements, and written scope.
Use calculators first
Build a planning range before contacting contractors
Home Upgrade Costs calculators are planning tools only. Final pricing requires contractor inspection, measurements, permits, and written scope.
