Installing DryJoistEZ


From Our Customers

DryJoist EZ is what I purchased. I wanted a dry screen room under the deck… After evaluating several different options to ensure a dry space underneath, I am so happy I went with this system.

The build quality is outstanding. Very sturdy, yet light… A very innovative, simple, elegant design. The customer service was also excellent. I got a person on the line very quickly, and they are all very knowledgeable. I got my questions answered on my first call, plus some additional advice…

On my next call, I ordered the product. It arrived on schedule (I wasn’t in a hurry), it was well packed, all the pieces were there, no damage, and all the dimensions were spot on…
This product made my job easier and quicker. My deck is longer-lasting, completely water tight, absolutely structurally sound, and probably better looking…”
