Reviews
What Montgomery County homeowners say
"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."

Cedar privacy fence · $8,400
"We got four quotes for a composite deck. A-1 was the only one that showed up with drawings and explained the footing inspection. Three years in, not a single popped fastener."
David R.
