Underdecking
CREATE A BEAUTIFUL NEW OUTDOOR LIVING SPACE




The PERFECT ADDITION to your Home
RainTight Decks gives a low profile, streamlined finish that creates a ceiling below the joists of your deck. Our panels and gutters are all seamless, smooth-finished aluminum that is virtually maintenance free and last a lifetime. RainTight Decks have been carefully designed to provide the BEST system for underdeck protection. Our rigid, heavy gauge aluminum will hold up to any amount of rain or snow….GUARANTEED!
Make the Most of Your Outdoor Living Space with RainTight
The weather in the Midwest and Southeast can fluctuate often, sometimes from one day to another. Even when the weather is pleasant enough to enjoy the outdoors, blazing sun, rain, and strong winds can send you running for indoor shelter. And if you don’t have those factors keeping you in, the annoying insects and pests will.
RainTight has unique solutions that allow you to enjoy your existing deck, patio or porch without the negative side effects. We can build on your current outdoor structures that provide shelter and shield you from the weather and pests that invade your space.

Underdecking
We seal the floor of your above-ground deck and install a “ceiling” beneath it to make the space below it more usable. We even offer kits you can order for DIY-ers.

patio covers
Our permanent patio covers will protect you from rain and the sun’s rays when you sit outdoors. We can easily convert the cover to a fully enclosed space down the road, if desired.

screen enclosures
We install a screened enclosure around your existing patio, deck or porch, then attach a permanent roof over it for additional protection.

Long-Lasting Quality and Durability
Our outdoor enclosures are all made of high-quality aluminum. We don’t use other materials like vinyl or wood because they don’t provide the same strength and durability. Our ceilings and patio covers are lightweight, yet strong enough to mount a ceiling fan or light fixtures. The covers will withstand any amount of rain or snow without bowing or cracking.
Our enclosures are made to last and require very little maintenance. They are rust-proof and resist fading. They are available in several colors to complement your existing décor. The colors are baked-in, not painted on, resulting in long-lasting beauty that doesn’t chip or flake.
Affordable and Convenient
Unlike new construction, RainTight’s solutions are much less expensive because we build on structures you already have in place. That means no digging, pouring concrete, or people trudging through your yard and home. No need to uproot trees or vegetation or rearrange your landscaping. You’ll get your beautiful outdoor enclosure within 4-6 weeks, as opposed to waiting months for a brand-new one built from scratch.
