Grow Your Green Thumb With Your Choice of Custom Conservatories

No other style of Eureka sunroom installation is as dramatic and eye-catching as a conservatory. That’s because this design features pane after pane of sparkling windows—even the roof is made of windows!

Your plants will also appreciate the warm rays of sun that our conservatories allow into your home in every season, making it possible for avid gardeners to tend to their plants year-round. Unlike the inferior-quality glass used by many of our competitors, the exceptional thickness and quality of our glass roofs means that our spaces are even better at keeping the indoor temperature consistent. We use the latest in glass technology to for the ultimate protection against solar heat.

Patio Covers Allow You to Get the Most out of Your Outdoor Space

Is your existing outdoor space not being used to its fullest because it gets too hot and uncomfortable under the rays of the sun? Do you wish it was a more enjoyable space for spending time outside with friends and family? Patio covers om C-Thru Sunrooms are the perfect solution!

We can easily create a brand-new space or alter an existing deck or patio on your Eureka home to provide you with a perfectly protected area for relaxing or entertaining.

Low-Maintenance Screened Rooms

Sunroom additions can be beautiful, but they can cost a lot of money and, with all that glass, they can also be high-maintenance. If you’re looking for a more affordable, low-maintenance way to enjoy the weather, choose from our screen rooms.

We guarantee you’ll love your new space because:

  • It can be customized to match the existing architecture of your home.
  • We can build a new screened room, or we can modify your existing deck or patio space.
  • Our structures are backed by a transferable manufacturer’s warranty.

All Season Rooms are Great All Year Long

Although Eureka enjoys mild temperatures throughout the year, it can still get unpleasantly chilly in the winter and hot in the summer!
