About Us

RainTight Decks was established in 2007, founded on over 80 years of combined engineering, construction, and development experience. Today we are one of the premier companies in the U.S. providing unique outdoor enclosures.

  • Under decking. We manufacture and install watertight ceilings beneath your home’s current above-ground deck. We also sell kits for those who prefer to install it themselves. No permits are required for this system.
  • Enclosed Screen Rooms. Our screened enclosures and permanent overhead cover can be installed around your existing patio, deck or porch.
  • Patio Covers. Permanent, watertight roofs will be installed on your patio. They can easily be converted later into a fully enclosed space.

Quality and Value

At RainTight, we believe in providing a quality product at an affordable price. Knowledge… attention to detail…and a commitment to quality: These are the real keys to a project’s success.

We only use high-quality aluminum for our enclosures, with screens made of fiberglass. Aluminum is better than vinyl or wood because it’s durable, won’t rot or rust, and will withstand severe weather. It comes in a variety of baked-in colors that won’t chip, fade or peel. The ceilings are strong enough to support fans or lighting.

And nothing helps RainTight deliver more than our people. From the experience and leadership of our management to the skill and quality workmanship of our tradesmen, we hire on the best to work on every facet of your project. We never use sub-contractors. Why? Because we want your project done right – the very first time.

What Makes Us Different

RainTight’s original specialty was under deck systems. What makes RainTight different than other under deck systems on the market is our dedication to giving customers a high-quality product that is budget-friendly and will stand the test of time.

That’s why RainTight developed its own unique installation process – to ensure a product that will provide beauty and function year after year. RainTight is proud to manufacture the RainTight Under Deck System with all components made in the United States. We give customers the option of having us install the under deck system or purchasing our kit to do it themselves.

Our Process

We start with a free consultation, where a professionally trained estimator will come to your home and measure your space. This ensures the end product will be customized to the exact size of your deck, patio or porch. You will not have to pay for any extra material from suppliers due to length or size restraints. We custom make each piece of the structure, which minimizes cost and installation time.

Locally Owned and Operated

RainTight is centrally located, with the headquarters and manufacturing facility located in O’Fallon, Missouri.  We service homeowners in St. Louis, St. Charles, Chesterfield, O’Fallon, MO, Ballwin, Wildwood, St. Peters, Kirkwood, Creve Coeur, Wentzville, and Maryland Heights.
