Benefits of Wood Decking

One of the main advantages of wood decking is its natural beauty. Wood decking comes in a variety of species, each with its own unique look and feel. From the warm tones of cedar to the rich reds of IPE, there’s a wood species to suit every taste and style.

Another benefit of wood decking is its durability. With proper maintenance, wood decking can last for decades, making it a great investment for your home. Plus, wood decking is easy to repair if it does become damaged, which can save you money in the long run.

Wood decking is also environmentally friendly. Wood is a renewable resource, and many decking materials are harvested from sustainably managed forests. Plus, wood decking has a lower carbon footprint than other decking materials, such as composite or PVC.

Building Your Dream Project

Floyd Stokes
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!
Julian Morris
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.
Nicolas Henderson
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.
Richard Washington De Campos
My better half has been making calls to get rooftop deck prices. We found Art pretty quickly. He managed the consultation deftly and refrained from pressuring us into signing anything. He is very knowledgeable and friendly. His estimate was comparable to those we had previously obtained. The quality of the job is amazing, though. Despite the fact that it was January, Art handled every aspect of the approval procedure, and our deck was constructed in a short amount of time. The effort of Art and his colleagues has greatly impressed us.
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!!
Marcos Vinicius De Jesus Silva Dos Santos
Art and his crew did an excellent job building our new fence and deck in the backyard. Art came to our home to explain the project and answer our questions when my neighbours and I opted to split the cost of a fence. They built a cost-effective, high-quality product, and they were a pleasure to work with. We are very grateful to Art and the rest of the team!
Nikolas Moreira Santos
Our stunning two-story wood deck goes above and beyond what we expected. A very high-quality, aesthetically beautiful, and clean end product was created by Art and his team. They are also very effective. Working with Art was a delight, and he handled all the required city paperwork with ease. The finished product is superb...
Greiziana Ribeiro De Souza
On the second story, Demex built a balcony deck for us that is around 450 square feet in size. Demex also constructed a waterproofing system beneath the composite-material deck to safeguard the area below it. Everything went out well, and the quality of the work itself is great. It's obvious that Art and Andrew are very knowledgeable and skilled. Our emails received prompt replies. Because of the plans they provided for us, we were able to obtain a building permit swiftly and without having to make any further inquiries. Art was helpful and understanding as we explored the materials' potential uses. They had outstanding logistics in place to deliver our orders on schedule. Their workplace was consistently tidy and organized. They worked quietly and diligently, accomplishing their daily tasks and more. Working with Demex was an easy and clear process that produced good results. We have no hesitations in recommending Demex based on our experience...
Gleydson Felipe Leite Santos
Our worn-out wooden deck was just expertly refinished by Art and his team. The previous boards were removed, and their replacements, together with metal handrails, were put in. The guys completed the task quickly, expertly, and successfully. I have no issues with expressing my enthusiastic support for this group because I have been entirely satisfied with their work...
