How to Verify a Maryland Window Contractor License

Why You Should Check A Maryland Window Contractor Before Work Starts

Proof Points That Matter Before The Crew Arrives

What To Ask Before You Hand Over A Deposit

• Have you completed window replacement in homes like mine before?
• Who will be on site, and who supervises the install?

If the contractor changes the subject, avoids the question, or seems irritated by basic verification, that tells you something.
