Basement Reno

Diego and his crew were fantastic to work with and kept us in the loop every step of the way. While we had several added expenses along the way (always an issue when opening up an old basement) everything was taken care of and we are very satisfied with the result and we now have a completely new basement that we can enjoy for years to come. Highly recommended!

Keith in Hamilton

Basement Renovation

We had a wonderful experience with Harmony basements. They are prompt, professional and skilled at their job. Their prices are reasonable. Diego and his team are wonderful to work with. Special shout out to Diego who was very patient in answering all our questions, giving us good suggestions in maximizing the space in our basement and Stefany who provided great design suggestions. Overall, we are extremely pleased with the outcome.

Finish Basement

Harmony Basements brought a level of professionalism that ensured my project was done on time and on budget. They were very responsive to every issue / concern I brought up and made every effort to ensure I would be truly happy with the end result. I really enjoyed working with them and have no hesitation to give them a 10 star rating. I will enjoy my basement for years to come.

Robert in Brampton

Main Floor/Basement Framing And Drywall

I had Rob frame and drywall the main floor and basement at my property. He did a remarkable job. I really appreciated him showing me what he was doing to help improve the overall look. Very knowledgeable and great to deal with. Will definitely use them again. Amazing work!

Doug in Mississauga

Basement Reno

Having never done a major renovation before it was really helpful to have the whole team at Harmony Basements assist us through each step. The project took a major turn when we discovered some structural issues, but Diego and his crew made sure we understood all of our options and gave us the confidence we needed to make the right decision. We are extremely please with the finished product, but we are just as pleased with our experience working with Harmony.

Thank you Harmony Basements for the outstanding job with our basement. From the get-go, the team were total professionals. They showed up on time and got straight to work, always keeping me in the loop and making sure I was happy with the progress. They took the time to listen to my ideas and concerns, and either incorporated my ideas or suggested better ones in the final design. We are happy with the end result and I'd definitely recommend your services to anyone looking to renovate their home.

We moved into a new house during the pandemic that had an unfinished basement. It was a difficult time but Harmony Basements managed to turn it into a wonderful legal basement apartment as quickly as possible. Every part of it is done perfectly. From the lovely flooring, the gorgeous stone wall and fireplace, to the beautiful kitchen and bathroom with glass shower and tiling. All was done with safety in mind even down to the foundation check and we passed inspection with flying colours. I am now enjoying living in my very own private apartment !

Amazing service end to end.Our family needed additional living space as we are expecting our third child.We needed a reliable, thorough, organized and cost efficient company that could facilitate all the items we needed for our basement.With luck, we were able to connect with Diego and the team at Harmony Basements just before Christmas to get work estimated and started just in time for the holidays.Every trade was punctual and did an amazing job. They were able to meet the completion timeline without any major delays.Would definitely recommend Harmony Basements to friends and family.

Finishing a basement is a big financial investment and after a few quotes we went with Harmony Basements. Their standard finishes were a lot better than the other places we looked at. Working with Deigo and Pablo to design the layout and finishes was great. They were both helpful and responded quickly to questions or concerns. The job was finished on time and Deigo was here inspecting and making sure everything was done correctly. Overall we are happy with the finishes and customer service and are enjoying our finished basement.

Calling Diego and his team experts in their field would not be an exaggeration! Their work is top notch . From day one until completion there was a dedicated team on site . A true example of proper project management.The attention to detail is spectacular from framing ,drywall, painting, hvac ,electrical to plumbing, the finished basement exceeded our expectations!No matter how many questions we had, we always got a prompt response and we always felt that we were the most valued clients !!No hesitation in recommending Diego and his team for your basement renovation needs.
