FAQ
Decks questions we get weekly
Does composite decking get too hot in Maryland summers?
Dark composite boards do heat up in direct sun. Lighter colorways and PVC products like AZEK run noticeably cooler. We walk you through surface-temperature differences before you pick a color.
Do I need a permit for a deck in Maryland?
Any deck over 30 inches above grade, or attached to the house, requires a permit and inspection in Montgomery and Howard County. We handle the drawings, filing and inspection scheduling.
Can you repair or resurface my existing deck?
Often, yes. If the framing and footings are sound, we can replace just the decking and railings for a fraction of a full rebuild. We inspect the substructure first and tell you honestly which way is smarter.

"A-1 replaced 180 feet of failing chain-link with cedar board-on-board. Cesar walked the property line with our neighbor before starting, which prevented a dispute we were dreading. Permits were handled and the crew finished in two days."
