Transform Your Deck, Patio or Porch into a Sunroom

When thinking of sunrooms, Austin residents may expect only brand-new sunroom installations where there wasn’t anything before. Although that’s a popular option, it isn’t your only option. We can transform your existing outdoor space into a brand-new sunroom with our innovative enclosure systems.

Because we're able to utilize an existing deck, porch or patio, we can complete your sunroom installation in as little as just a few days. With sound proofing and energy efficient construction, you’ll enjoy spending more time on your deck when you have it enclosed by C-Thru Sunrooms!

Take Advantage of the Austin Weather with a Patio Cover

A sunroom in Austin is a great solution for some homeowners, but for those who want to retain their current outdoor space, a patio cover is the best solution. Duralite glass and Futurewood construction ensure your patio cover won't rot, chip, or splinter. We offer patio covers in curved and straight eaves for a stylish finish.
