Composite Deck over Concrete Patio in Waukesha, WI

This homeowner had an aging concrete patio that no longer fit how they wanted to use their backyard, so they brought in Sennott Contractors for a custom deck build in Waukesha, WI that would open up the space and eliminate ongoing maintenance. Rather than tie into the failing slab, our crew engineered the new structure from the ground up on Diamond Pier footings, a helical foundation system that resists frost heave and delivers dependable load-bearing support in Wisconsin’s freeze and thaw cycles. With the frame set level and square, we surfaced the deck with Trex Rocky Harbor composite decking and wrapped the perimeter in matching Trex fascia to conceal the framing and create a clean, finished edge. That attention to detail is what separates professional deck construction in Waukesha, WI from a basic board-over-slab approach, and it is why the boards run true across every span. The result is a significantly larger outdoor living area that transitions seamlessly from the sliding doors into the yard, ready for furniture, gatherings, and everyday relaxation. Because composite decking never needs staining or sealing, this Waukesha, WI family gained years of enjoyment without the upkeep that comes with traditional wood. Projects like this reflect the deck design and construction experience that Sennott Contractors brings to homeowners throughout Waukesha County. When you are ready to convert a tired patio into a durable composite deck built for the long haul, bring your Waukesha, WI project to a crew that builds it right from the footings up.
