General Contractor Quote Comparison Tool

Use this before hiring a GC for a multi-trade project. It helps you collect the same assumptions from each contractor so the lowest number is not hiding missing scope, allowances, permits, or coordination work.

Prep before quotes

Send the same scope, photos, drawings, finish expectations, and timing goals to every contractor.
Ask each contractor to separate included work, excluded work, allowances, permits, disposal, cleanup, and warranty.
Keep a quote comparison table so scope gaps are visible before price comparisons.
Write one room-by-room scope list and mark what stays, what is removed, and what is replaced.
Collect existing photos, rough goals, property constraints, and must-have dates before asking for pricing.
Mark the work area and note any access limits, parking limits, pets, tenants, or work-hour restrictions.

Why GC quotes are hard to compare

General contractors can include different assumptions for permits, demolition, disposal, site protection, materials, allowances, subcontractors, schedule, and cleanup. This tool helps expose those assumptions before you compare prices.

The output is quote prep, not a permit ruling, engineering decision, health assessment, or final scope. Confirm technical and legal requirements with the relevant authority and qualified professionals before work starts.

Four details to settle before quotes

These are the assumptions most likely to make two quotes look similar while covering different work.

Scope line items

Require written inclusions and exclusions for demolition, rough-in, finishes, cleanup, and disposal.

Schedule assumptions

Ask about start date, lead times, inspections, owner decisions, and what can delay the project.

Permits and inspections

Clarify who applies, who pays, who books inspections, and what happens if revisions are required.

Allowances

Cabinets, tile, fixtures, flooring, hardware, lighting, and appliances should have realistic allowance numbers.

General Contractor tool FAQ

How do I compare two general contractor quotes?

Normalize scope first. Compare the same drawings, included trades, permits, allowances, exclusions, warranty, schedule, site protection, cleanup, and change-order process.

What is an allowance in a renovation quote?

An allowance is a placeholder amount for a selection such as tile, cabinets, fixtures, or flooring. Low allowances can make a quote look cheaper before real selections are made.

Should a GC handle permits?

Many GCs coordinate permit steps, but responsibility should be written down. Ask who applies, who pays, who books inspections, and what is excluded.
