Use supply links carefully

  • Confirm bid inclusions. Use product links to spot materials and parts that should be included, excluded, or allowance-based.
  • Keep labor separate. Product prices do not replace contractor labor, permits, code work, warranties, or site conditions.
  • Compare like for like. Open the calculator and worksheet when two bids list different supplies or unclear material grades.

Project supply FAQ

How should I use project supply checklists?

Choose the project type that matches your estimate, such as exterior home projects, mechanical and utility projects, and plumbing and septic projects, then open the matching calculator supply section. Use the product links to recognize common parts, tools, fixtures, safety gear, and cleanup supplies before comparing contractor bids.

Are product links contractor quotes?

No. Product links help with planning and price-checking common supply categories. They do not include contractor labor, permits, disposal, warranty coverage, site access, or code work, and they do not promise contractor availability.

Where do supply checklists fit with calculators and worksheets?

Start with the calculator for a planning range, use the supply checklist to spot material categories, then use the quote comparison worksheet when two bids include different products, allowances, cleanup items, or warranty assumptions.
