What is everyone saying?

9/10 Review on - Dealt with Marc in the initial stages, very professional, good to deal with and seemed knowledgeable (their competition wanted 100% payment upfront, Marc was much more reasonable to deal with). Spencer and Rick came to do the install, and put a long day in to get everything wrapped up in the one day. The installation was done very well with great attention to detail. They identified one problem that required some extra labour, which I authorized up to a certain amount, and the extra charge came in roughly half of what was authorized. I would do business with them again.

9/10 Review on - We had a tear in our third storey decking which happened to be over two bedrooms. Because of this and possible water damage we were put on priority to finish the job ASAP. Of course weather in Calgary (summer 2016) wasn't exactly cooperative, but Caldek did the under deck repairs, put on a temporary patch and replaced the Duradek as soon as the weather cleared up. Cost seemed a bit high, but overall I was happy with their work and the results!

10/10 Review on - "All work was finished on time. Any small items were attended to immediately. The installers were very professional and coordinating with Brian in the main office was very efficient. Brian contacted us upon completion of the project to see if there were any remaining issues to be looked after. Very satisfied with the workmanship and quality of the products used."

We had Caldek install Duradek on our backyard deck. From the estimate to the installation, everything was great. They were professional and provided a very competitive rate and did the job in a timely manner. The installers did a fantastic job and we are VERY HAPPY with our deck. We highly recommend the folks at Caldek.
