I have worked with John in the past on trim and mouldings in our century home. Recently we were thrilled that he could restore some pillars that were rotten on our porches. He built a new large porch and we are very happy with the results. We were also very pleased with the custom woodwork made to reproduce woodwork over our windows. I would recommend him highly. John is great to work with and really knows his craft. He is reliable and punctual. I wouldn't hesitate to use him on a future project

John and his team worked diligently to make major repairs to our large wooden front porch. The quote for the work was detailed and understandable, especially compared to others we had received. The work itself was done efficiently. The team arrived on time each day and cleaned up properly. John himself came regularly to review the progress with us. The final result was outstanding. The work included special measures to prevent animals from accessing beneath the porch. The materials used for the porch were first-rate as was the craftsmanship. In summary, a 5-star effort.

John and his team were fantastic. They were always professional, polite, early, tidy, and my husband and I were both thrilled with the quality of the custom deck they built for us. We requested a custom corner bench, as well as glass railings and we were very happy with their work throughout the whole job. It was especially impressive that they built the whole deck within 2 weeks and in time for a party we hosted with only the glass ordered to arrive later as John explained when we started the job. Thanks again John and team, we were so happy with everything and we'd certainly recommend them to a friend.

John recently repaired my deck, and I couldn't be happier with the results! From the initial consultation to the finished project, John was the consummate professional. He listened attentively to my concerns and provided insightful, practical advice on the best way to address the repairs. His workmanship is top-notch, and it's clear he takes great pride in what he does. The deck feels sturdy and looks fantastic. Not only did he complete the work efficiently, but he also made sure to clean up thoroughly afterward. If you're looking for someone reliable, skilled, and who offers honest, valuable advice for your deck repair needs, I highly recommend John!

John & his crew did an impeccable job of installing a wooden privacy screen on my deck. The work was fast, neat, & they did a great job of cleaning up behind them! I would recommend them for any deck, or fence work. Plus… they are all such nice gentleman. One happy customer :)

John and his team were most excellent to work with from start to finish. John provided all the information we needed during the quotation process for my wife and I to make an informed choice. His communication was fast and he continued to answer all of our questions during the process. His team were equally great during installation, ensuring we understood what was happening and answering any questions we had. We are so happy with the result and are now enjoying our new backyard space. We would highly recommend John and Mississauga Decks and Trim to anyone looking to update their deck or backyard space!

I highly recommend Mississauga Decks and Trim for any deck project. I searched for a deck provider and selected John and his team to replace our outdated deck. Quick responses, highly experienced consulting and full-service capabilities make the planning easy. After an initial briefing, John provided a comprehensive quote that met our timing and budget. Once approved, John’s crew started work on the project and provided timely updates. Completion was quick and we love our new deck. Thanks John.

I am very satisfied with Mississauga Decks and Trim. My first contact with the company was both a surprise and a delight. When I phoned MDT to inquire about having a composite deck built, I expected what usually happens when one calls a business – i.e. leaving a message on voicemail and then waiting for a return call -- sometimes, one that never comes. This wasn’t the case at all with MDT: John Morrissey, the owner of the company, answered my call directly and spent a good twenty minutes answering my questions and asking questions himself to ascertain the scope of the project. He set an appointment for the next day. At that appointment, he examined the surroundings (e.g. house colour, tree canopy, etc.), carefully took measurements, explained options, made recommendations about design and materials, listened to my requests, answered more questions and provided valuable insight so that I could make informed decisions. He was honest, patient and personable. He didn’t try to upsell me, and he spent time investigating whether composite gates had evolved to a point where one might be a viable option. John returned on subsequent visits with samples of composite and railing. He provided me with an estimate, which clearly outlined a payment schedule. I appreciated his professionalism. When the contract was signed, the project moved forward. MDT arranged for the utility locates. My existing wooden deck was demolished; helical piles were installed; a new sub-structure was built; and chicken wire was also installed as an underground barrier against marauding animals. At the end of the project, I had a beautiful composite, picture-frame deck with boards set on a 45-degree angle, a complementary aluminum railing with a drink rail, and a self-closing gate. John and his crew, Art and Alonzo, worked tirelessly in both extreme heat and cold. They listened respectfully to my ongoing questions and provided answers; they explained what they were doing and why. I appreciated that they took time to help me understand the process. When I had a concern about three of the boards being a slightly different colour, the issue was addressed and resolved, to my satisfaction. As is often the case with construction projects, there were some inevitable delays; when this happened, John once more kept me informed as to what was happening and why. He always answered emails and returned phone calls. MDT also took my schedule into consideration when scheduling their work, and I appreciated that very much. Moreover, I always felt that my project was important to MDT, even though it was on a smaller scale than many of their projects. Before my final payment, I received a revised estimate that was somewhat lower than what was originally quoted. This was because, when the old deck was demolished, it was determined that fewer helical piles were needed than originally thought. This downward adjustment of the cost is yet another proof of John’s honesty and integrity. I recommend John Morrissey and MDT without reservation to anyone seeking a knowledgeable, experienced, highly skilled team of deck-building professionals, whose work is superb and for whom customer satisfaction is of paramount importance.

I had a great experience working with John. Very professional and responsive, and was helpful in providing us with options for our project. Took the time to explain the various details of the project, including how things would be constructed, cost breakdown, and benefits of one option over another. Would highly recommend for anyone looking to build a deck.

Amazing service and high quality craftsmanship from John and Art! They are a pleasure to work with, and we get many compliments on our deck. The composite material we picked is perfect for our young kids who love to play and run around on it. Highly recommend!

I coud not reccomend John and his team enogh. My deck came out way better than envisioned. They were on time, professional and very skilled. The best part was that we paid exactly what the quote said because everything was explained before the project started.
