Testimonials / What our clients are saying about us

  • I wanted to let you know the UnderDeck product installed beautifully and has worked flawlessly through a number of rains and snow melts so far this fall. We also were able to wrap and gutter the triple joist with no problems or leaks. I’ve had a number of friends take a look at what I did.  Who knows, they may become future customers for your company.

    One piece of advice is you may want to recommend that people order one extra piece for a few of the items in case they make a mistake.  It may cost a bit extra but it saves time and money in the long run if you have to do a second order like I did.

    Thanks for all of your support.

  • I am quite happy with how the systems have performed over the last 10 yrs. I was skeptical at first that the material would "hold up" in our Colorado, high mountain climate. We also had to paint the entire system prior to install due to strict Design Review Board guidelines, but it has performed extremely well. I now have 3 different clients that would like to purchase a system.

  • Great product! My Customer loved it and it was easy to install. I just gave your name out to another contractor that was looking for a waterproofing system. I will be using UnderDeck The Original again. Thank You!

  • UnderDeck The Original installation was pretty easy to work with and everything we needed was provided in one shipment. It looked great, and we have had some very serious rain showers since it was installed. My customer has had no complaints. I would definitely recommend FehrMark's under decking again on future products!
