Local Contractor Directory

Find Home Improvement Contractors
in Your City

Browse local businesses for repair and improvement projects. Some listings are claimed, while others come from public records and are marked unclaimed. Grant-Approved is The Grant Map's own label after a separate review of a claimed contractor's program experience, not a government endorsement. Always verify licensing, insurance, and fit before hiring.

For Contractors

Free listing. Clear choices for each lead.

Homeowners can expressly request contractor routing after researching possible programs. A request that passes routing checks may create a contact-free offer for a compatible active contractor; it is not sent with full details to every contractor. Name, contact, property address, and free-text unlock only after explicit signed-in acceptance and any required finalized payment.

01

List for $0

No card and no monthly subscription. A profile label appears only after separate manual review and is not a government endorsement.

02

Review a contact-free offer

Your first accepted compatible lead can use a free credit when available. The homeowner's contact details remain locked until explicit acceptance.

03

Choose before paying

Later offers show the exact one-time price before acceptance. Ignore an offer and pay nothing; paid contact access waits for a finalized charge.

Eligibility, funding, contractor contact, and a job are not guaranteed. Verify project fit before accepting an offer.

Apply to Join the Network

Get your business in front of homeowners researching repair funding and asking for contractor help. When available, a lead preview can carry possible program names and stored program context to verify; it never means an application is complete or funded. New registrations are reviewed before activation; an existing public-record listing can be claimed by verifying control of its business email or phone, which may activate it immediately under the current claim policy.
