About the organization
A Clearer Standard for Home Improvement Information
The National Home Authority is an independent consumer resource dedicated to improving transparency, professionalism and accountability within the residential construction and home improvement industries.
NHA develops published evaluation criteria, reviews contractor practices, provides homeowner education and establishes certification standards intended to help consumers make more informed decisions before entering into a home improvement contract.
Our purpose is not to replace a homeowner's independent research. Instead, we provide an organized framework for evaluating important factors such as licensing, insurance, reputation, warranty coverage, business history and complaint response practices.
Important disclosure: National Home Authority is an
independent private consumer-information organization.

Before signing a contract
Six Steps for a More Informed Hiring Decision
Homeowners should complete their own review of every contractor, product and proposal before authorizing work or making a payment.
01
Obtain Multiple Proposals
Request at least three written proposals whenever practical and compare scope, materials, warranties and exclusions—not price alone.
02
Verify the Company
Confirm the contractor's legal business name, address, phone number, website, licensing and insurance information.
03
Review the Contract
Require a written agreement that clearly identifies the work, products, payment schedule, estimated timing and warranty terms.
04
Investigate Reputation
Review multiple information sources and pay attention to complaint patterns, not merely the contractor's overall star rating.
05
Understand the Warranty
Determine who provides the warranty, what is covered, what is excluded and whether labor and materials have different terms.
06
Avoid Pressure Decisions
Be cautious of unusually large deposits, urgent same-day offers, incomplete documents or pressure to sign before reviewing terms.
