Custom-Designed Decks

Your backyard has the potential to be more than what it is right now. With a custom-designed deck or porch from Erdmann Exteriors, you can transform your yard into an outdoor living space where you, your family, and your friends will want to spend as much time as possible.


Custom Deck Construction

From weekend barbecues to evening cocktail parties under the stars, a custom-designed outdoor space built by the most experienced deck builders in the Chicagoland area can tap into the potential of your backyard and add untold value to your home.

Erdmann Exteriors can transform your backyard into an outdoor living space that can bring the features and amenities of a kitchen, dining room or living room outside. An outdoor living room complete with outdoor lighting makes a perfect space for entertaining. An outdoor bar gives you a great place to gather with friends and family while taking advantage of the weather. A cabana allows you to enjoy your outdoor space without worrying about being bothered by insects or the occasional raindrop.

Our Process

Our process begins with our free in-home consultation, during which we will talk to you about your desires and take measurements to help us make a recommendation that will meet your exact needs. If you have specific ideas for your new outdoor space inspired by something you saw in a magazine or on Pinterest, we’d love to see it.

After that initial meeting, our deck designers get to work creating a proposal that matches your expectations. We’ll show you product samples of building materials and help you determine exactly what will best meet your needs. Once we help you finalize the design, we will work closely with you through every aspect of the pre-construction and construction phases until we have a finished product that will make you completely happy. We’ll clean up the site to make sure nothing is left behind, and we’ll take you on a detailed walk-through and resolve any lingering issues within seven days.
