Who is Platinum Decking?

Who is Platinum Decking?

Our mission is not only to build your dream deck but make working with us a truly Platinum experience. 

Platinum Decking is your personal consultant, designer, and builder, dedicated to building you a deck that transforms your outdoor living space. Our team’s dedication to our customers takes priority. With over a decade of industry knowledge, combined with our team’s relationship-first mindset, we promise every one of our clients a seamless and enjoyable experience start to finish. What we do stems from an honest passion for the outdoors and bringing that lifestyle to your very own home. 

Having grown up in Milwaukee, with hunting land towards Madison, and vacationing up North, Wisconsin is in our roots. From the golden farm fields of East Troy, the rolling hills of Black Earth, and Minocqua’s serene north woods, Wisconsin’s natural landscape is meant to be appreciated.  At Platinum Decking, a deck isn’t just a structure, it’s an extension of your home; a place to bring together friends and family.  Whether you’re gathering around a fire, throwing a summer party, or enjoying the fresh air and some relaxation.  Creating memories that last a lifetime starts with a beautiful deck space that lasts just as long.

Platinum Decking vs. average deck builder?

From top to bottom, structural and aesthetic, the quality of your deck is directly reliant on the know-how of the builder. There are a lot of contractors that can build a deck, but there is a big difference between a contractor and a deck builder. Your average GC provides a variety of services needed for the exterior or interior of your home; carpentry replacement, gutters, concrete, to name a few. By design, it’s often they will only build a handful of decks each year among everything else and the crews are outsourced due to the rarity of service. The concept proven over and over again is that you’re better at something the 10th time you do it, vs. the 1st, and even better the 100th time than the 10th.  

At Platinum Decking, we specialize 100% of our business into building only high-quality decks, with a specialization in composite material.

Our decks are high quality, built to last, and stand-out beautiful, thanks to our in-house dedicated and highly talented builders. Every one of our crews are Platinum Decking employees that are with us full time and year-round. This allows us not only to maintain consistent quality in our work, but it gives our guys the opportunity to be absolute masters of their craft. Every single builder with Platinum Decking is an important part to our promise to you; that start to finish, a Platinum standard of quality and customer service is something you can count on.
