Sunrooms are all about comfort and what you are comfortable with. But what type of Sunspace® would best fit your family’s lifestyle?

  • Do you cherish the sensations of a spring breeze dancing across your skin while breathing in the scents of the flowers and trees as they bloom around you? Then a screen room might be your best choice.
  • Do you like to watch the green of summer grow across your backyard, and then months later watch as the leaves turn vibrant shades of red and orange, all while without feeling the fiery bite of summer or the cool chills of fall? A sunroom may be your best.
  • Do you want to relax in a climate controlled oasis that will keep you warm as the snow falls, and cool when the summers get just a little too hot? Then a 3-season or 4-season Sunroom may be the choice for you.
    Whichever sunroom you choose, you are making an incredible investment in the aesthetic and feel of your home. Having a comfortable outdoor getaway gives you and your family another space in your home to enjoy, while also bringing the serenity and beauty of the outside world to your backyard at a level you are comfortable with.

Sunrooms St. Louis, Missouri and Illinois – FAQ

What is the Average Price of a Sunroom?

Our biggest seller is the 3 Season Sunroom with WeatherMaster Vertical 4 Track Windows.

The most common average size is a 12×12; however, we customize our rooms for every customer.

It is hard to provide an average price. Why? Here are Several Reason:

Our Sunrooms are customized for every project. It’s not just the size of the room that we have to consider.

We also have to look at how we will attach the room to the home. Will we tie into the fascia?

Will we need to tie into the roof due to height of the room?

What is the sunroom to be installed on top of? Meaning, does the customer have a concrete pad/patio? OR do they have a deck that we are putting the room on? If they do have either of these structures, are they built to hold the room?

Does the structure need to be updated to pass code? Are the piers installed correctly to pass code? Does the customer need a new sub structure?

These are questions that we have to have answered before we can provide you with an honest estimate for pricing and labor.

What are the Sunroom Roof Options?

Sunroom roof options: We can customize a roof to match your home, we can build a gable roof or shed style roof. We can install a modular roof as well. Either way, we can also install shingles to your roof to allow it to match your home.

Modular Sunroom versus Custom Built Sunroom.

Both sunroom options are great! Some customers want the room built to match their home so that it doesn’t look like an add on. This would then fall into the custom built sunroom. Some customers want our Sunspace Modular Sunroom option. They are very nice and are custom made. Some ask what is the most cost effective. The custom built roof will cost more in labor as it takes longer to build this type of room. The modular roof will cost more in materials; however, the labor and install is much faster as it is built at the manufacturing plant.

Are you able to work within my current space? We are specialists in “re-purposing” space. Complete custom fabrication to the 1/8″.

How long does the process take?

All projects are different, so it is hard to say how long. You also have to determine the time to order/receive products as well as weather.

Can you enclose my existing patio?

Can you enclose my existing patio? Yes, our sunrooms can be installed onto an existing deck or patio. We can also install under an existing patio cover or roof. We do this a lot as customers may have an existing patio or deck. They want a sunroom because they enjoy being outside, but the intense sun/mosquitos/rain keep them from enjoying being outside. If they have a patio roof already, but no patio or deck… we can build those as well. So, if they have a roof and platform – we can accommodate their wants. If they don’t, but want a complete sunroom – we can do this as well. The options are endless.


We enclose outdoor patios to allow restaurants and other commercial properties to provide outdoor seating for their customers.

This allows for: Customers to enjoy being outside without harsh weather, intense sun, bugs, rain, loud noises from the road.

It allows the business owner to offer this to their customers which a lot of times, it attracts more customers.

It also provides more revenue to restaurants who could increase profits if they have more seating for customers.

An example: The Retreat Gastropub has our enclosure. They are limited on their indoor seating. We enclosed their outdoor patio and they were able to increase their seating area year round.

They installed some outdoor heaters to allow year round outdoor seating. They also can open or even remove the light weight windows on nice days to allow for a full outdoor patio experience.
