Mequon landscapers install low-cost, low-maintenance composite decks for homes in Mequon, Whitefish Bay, North Shore, and beyond

The composite material Oberndorfer uses is made from wood and plastic, providing a wood-like look with none of the maintenance a wooden deck requires. Composite decks are durable through hot summers and brutal winters, and they don't require staining, sealing or painting.

"Replacing a 30 year old deck and added brick pavers too. End result is lovely! Took time and patience on Chris Oberndorfer’s part as he reworked the design several times to get it to fit into our budget. We ended up with a blend of pavers and treated wood deck/patio. What we appreciated about this business is that Chris not only is the owner but he was on the job each and every day with a crew of very nice hard working men. He worked alongside everyone so you know that the work was being done correctly. His reputation is on the finished project and he made sure it was done correctly. We also appreciated that as the old deck was pulled up it became apparent that downspouts and water drainage needed readdressing, and they took care of that. They could have easily just buried the issue with the new deck."

"Chris and his team have performed a variety of hard-scape and major plant material installations over the past two years as we transition this property from overgrown/neglected to a planned design. They have been both timely and flexibly responsive to a variety of work requests. We receive many compliments on our progress, which we expect to continue over the next several years."

Nice job! The crew was thoughtful and always polite. Stayed on budget even though Chris had to bring in more soil and gravel than what was in the quote. A pleasure to work with. Patio and fire pit look great!
