Here in Maryland very few builders or HOs are concerned with licenses only insurance. i got more work with cards that had NO license number than I ever did WITH it. Guys come down from PA and do everything from drywall to 3 story decks without a license. Guys come here from Delaware and do the same. Try to work in Delaware without licenses,bonds and county permits for all 3(yeah 3) counties...forget it. Nowdays if you DO have a license here the customer knows you'll want paid like an American and they'll call the hacks or illegals.
