About Home Upgrade Costs

Home Upgrade Costs helps homeowners understand planning ranges for major home upgrade projects before requesting contractor quotes. Our current coverage focuses on HVAC replacement, roof replacement, and EV charger installation.

Home Upgrade Costs is operated by Golden Dragon Global Supply Chain LLC.

What Home Upgrade Costs does

We publish project cost calculators and cost guides that help homeowners think through likely budget ranges, common cost drivers, and the details contractors may need before reviewing a project.

Homeowners can use the site to estimate a planning range, compare major project factors, and submit a project request when they want local quote options reviewed.

What we are not

We are not a contractor and we do not provide final bids. Calculators and guides are for planning only. Final quotes depend on local contractors, permits, materials, measurements, site conditions, and written scope.

Estimates on this site should not be treated as contracts, guaranteed prices, insurance values, appraisals, or a substitute for a written contractor quote.

Selected beta markets

Home Upgrade Costs is currently being tested in selected beta markets. Contractor availability is not guaranteed in every ZIP code, and coverage may vary by project type, local capacity, and homeowner timeline.

If you submit a request in an area where we do not yet have a matching contractor workflow, your request may be reviewed for availability before any follow-up.

For contractors

Contractors can apply to be reviewed for beta participation. Application review does not guarantee acceptance, lead volume, exclusivity, revenue, territory rights, or any specific project outcome.

Contractor beta details are available on the contractor information page.
