But what do our customers think?

“Sean Warren and his team are top notch. From the very beginning of our interactions Sean was professional and fully engaged to making our project successful. His quotes are detailed so the scope of what is “in and out” is clearly defined. Sean worked well with the structural engineer and architect even when things got really challenging as unknowns popped up. Sean works well with his team and they have a great work culture- it is clear there is a lot of respect and trust between them. There is good comradery while still focusing on quality workmanship and that was nice to see as the customer. We felt the entire time like Sean and the team worked on our project like it could be their very own home. They explained things along the way so we were kept fully engaged in the progress and any obstacles. We feel confident in the work that has been done on our front porch and would absolutely recommend Sean Warren Contracting to those looking for home renovations or building projects to be completed. I would actually recommend that you contact Sean prior to an architect as he can really help with what type of items are important to look for and understand what is important to you. We would have Sean back in a heart beat for another project.

The other thing that made it easy to work with Sean is that he is a good human! Kind, caring and a great person to be around. We are so happy to have worked with Sean.”

“Extremely happy with the finished product. It looked better than we expected. The job was completed in a timely manner and the price was quite reasonable. We highly recommend this company. The owner is a really nice guy and offers solutions that best suits what you are looking for. Job site was impeccable after completion. We love the space and use it every day. We will definitely be using this contractor for any future renovations.”

Gail, Aurora

“Sean listened to what I wanted and made my vision come to life for our first baby’s nursery! I was so impressed with how detail oriented he was and how quickly it all came together. I will definitely be calling him for our next home project and I highly recommend him!”

Samantha, Keswick

“Deck Reno/ upgrade was a success. Quick, reliable, exactly what I was looking for. Even with the shortage of materials do to COVID-19 They were still able to source out and retrieve materials to get the job done.”

Joe, Newmarket
