• Review the contract thoroughly, including payment terms, warranty details, and dispute resolution procedures.

Quality signals to look for

Look for contractors who provide transparent written quotes and are willing to explain their process and pricing. Verify that any contractor you're considering has proper licensing on file with the state—this protects you legally if something goes wrong. Be cautious of contractors who demand large upfront payments, insist on cash-only deals with no documentation, or pressure you to decide immediately. A professional contractor will have references available, carry appropriate insurance, and put agreements in writing.
