Looking for a brighter, more welcoming living space you can enjoy in every season, even the harsh winters faced in Chicago’s suburbs? A four-season sunroom transforms outdated patios or underutilized rooms into inviting, climate-controlled retreats.

We are beyond thrilled with our pergola and new outdoor living space! The process from start to finish was very straightforward and all team members were great to work with! We cannot thank Josh, Hayden and the rest of the construction crew enough for their hard work, excellent craftsmanship, and superior kindness!

Erdmann Outdoor Living built a screened-in porch on the back of my house and a small deck on the side of my house. This was my third project with Erdmann... This is a major reason as to why I've used Erdmann on so many of my house projects. I know they will be around for many years to come, and they will stand behind their workmanship and the products that they use.

As a realtor, and someone who is asked for advice on who to use to make their outdoor space true "outdoor living", I will always tell them to call Erdmann Outdoor Living. They are hands down the most thorough, detail oriented and quality outdoor living company that I have worked with. They take their time to understand what your goals are, are quick to answer questions, and have a great reputation of delivering exactly what they promised.
