CLIENT REVIEWS
We started our journey as a deck building company in 2010 and a few of our main rules are quality of work and customer satisfaction. Our customer testimonials prove it. Read the testimonials below!
Would recommend Art and the team for any deck project, very helpful from the outset and quality and responsiveness throughout the build was second to none. Could not recommend him more. Thanks for all your help.
Trex is quite expensive, and there aren’t that many people skilled in its use. Art and Andrew had transparent pricing structures. They were flexible with our requests for modifications and did not try to take advantage of us by charging more than necessary for the extras. The end product looks fantastic. Since finishing the deck, we’ve been having dinner there every single night. Andrew and Art are hard workers who showed up on time every day and put in a full shift. We would definitely hire them again!
Art provided a reasonable estimate and helped me through the building permit process. He and his team were very professional in their work, which included removing the old deck, building a new one, and cleaning up afterwards. Their workmanship was very neat and precise, and the finished product is beautiful. I would highly recommend him to anyone needing a deck.
We are very happy with the work from Art and the Demex Decks team. They were up front with what to expect, answered all of our questions and accommodated our requests, and worked through rain, snow, and sun to get the job done. Would highly recommend Art and Demex Decks for your next project. Thanks guys.
Our new Deck is fantastic. The experience of collaborating with Art from Demex Decks was rewarding. His work was meticulous and professional. The team put in a lot of effort to tear out the old deck and replace it with a Trex deck. The completion time was faster than we had anticipated. All of our queries were answered thoroughly, and the meticulous work left us completely satisfied. We have already told several people about Demex Decks and how great they are.
Art and his crew did an excellent job building our two-story deck. They were reliable, stuck to the initial price despite rising material costs, offered reasonable rates for extras, and exceeded building code requirements in some areas. Art's professionalism and adherence to deadlines were impressive. We're grateful for their efforts and happily recommend them!
Art and Andrew are pure professionals. Their quality of work and depth of knowledge is outstanding, they are punctual and reliable, fast and efficient and a pleasure to work with. Our recent project was the second composite deck installation we’ve done with Demex and we can’t imagine building a deck with anyone else!
Amazing service, affordable pricing, easy communication and deck installation. Thanks!
Art and his team were excellent to deal with from start to finish and all our questions where promptly answered. Great communication and extremely professional. Our deck looks amazing!
We recently had a pleasure of working with a truly professional and knowledgeable deck contractor, and we simply couldn't be happier with our experience and the final outcome. Art walked us through each step of the project seamlessly, ensuring we were fundamentally involved in all processes, decisions and fully understood every detail of the project.We have met with other contractors about this project, but Art’s professionalism stood out from the very beginning. He made two visits to our home prior to the start of construction to address any concerns, queries or else that we might have. His expertise in deck construction is evident as every question we had was answered with depth and clarity. Art always provided a practical and valuable advice, cautioning us about the pros and cons of each decision we were about to make. Moreover, schedule and cost were as initially discussed, and there were no surprises during and after construction. We also found Art to be easily accessible and approachable throughout the project. Even after the completion, he was responsive to any questions and concerns we had.
Art and his team completed decks at our home and office. The finished product is terrific. The folks at Demex were diligent, responsive, on time and on budget. Overall, a very good experience.
Art and his team from Demex Decks did a great job building our deck. We connected with Art last fall to discuss building a deck in the spring. Art provided us with some great suggestions on the type of decking and colour combinations to use, and it turned out that his recommendations were spot on.Throughout the process, Art and his team worked diligently and efficiently. They kept us informed about their schedule and stuck to it. We were impressed with their hard work and dedication to completing the project in a timely manner.Overall, we are extremely satisfied with the deck that Demex Decks built for us. We would highly recommend them.
The horizontal fence Art and Andrew built for us exceeded our expectations. They arrived when they said they would, provided reasonable rates, and cleared up after themselves nightly. The quality of their work is exceptional; we’ve received a lot of compliments from our neighbours about our new fence. I would strongly suggest Art for any future endeavours.
Our deck was recently completed by Demex Decks, and we are really happy with the outcome. They were reliable, effective, and enjoyable to work with. We are filled with awe and respect for their work!
There was a 15-degree drop in temperature during the project. Even so, Demex built the deck, which has two levels. I extend my deepest gratitude to the Demex team for the beautiful work they produced in November. Right now, we could use some warm weather. We are eager to utilize that deck.
Fantastic work was done by Art and the crew. The team quickly produced a high-quality fence by arriving on time, working quickly, and tidying up after themselves. I am thrilled with the calibre of their work and their attention to detail.
We came to Art and Andrew for assistance after receiving multiple quotes and having a difficult time deciding on the components and construction strategy for the replacement of our 30-year-old back deck. He gave us clear instructions and suggested the best items to use together. We had a multi-level deck with a cedar pergola planned, within the dimensions of the existing deck. The outcomes attained by Art and his team were astounding. In order to address structural difficulties and in accordance with the permit drawings, they first constructed a support structure before installing composite decking, railing, and a pergola. Consider Demex Decks if you want a stress-free deck installation.
Art is one of the most professional and attentive to details individual who I have ever worked with on renovation projects!He is super punctual, used quality materials, gave fair quote and finally deliver great looking results and extremely nice looking deck. He met and overachieved our expectations!I have no hesitation recommending Art and his team to build or renovate your deck!Thanks for your help Art!!
Art and his team did an outstanding job on our two-storey deck and we couldn't be happier. I am picky when it comes to home upgrades and they were great to deal with at every step of the process. Here is what impressed me about Art:1. He stuck to his promises with regards to timelines.2. He honoured his original quote even though material costs were increasing.3. His pricing was fair.4. His charge for accessories was very reasonable.5. He was a professional and did not over promise and under deliver.6. And, most importantly, he went beyond basic building code and overbuilt certain aspects of the structure without me even asking.Thanks for all your hard work Art and team...we really appreciate it and will be recommending you whenever we get the opportunity. We cannot wait to use our deck next year!
