After years of postponing work on our bathrooms because of the anticipated disruption to our routine, we decided on Trelli to undertake the renovations. I just wish now that we had known about them sooner ! Andrew, Gio , Brad and the Trelli team gave us the bathrooms we've always wanted. The work is beautiful and impeccably done. They answered all questions patiently and attended to every detail. The work was done within the time frame promised and on budget. The guys were professional, friendly and attentive, especially important since we remained in our home during the renovations. We could not have asked for anything more !

We had such a great time working with Andrew, Mike and their entire team renovating our home. Their team is respectful and a pleasure to be around. Always open to extremely great constructive conversations, and the communication is absolutely top. I look forward to getting to work with them again.

Trelli was recommended to us by a friend after we had shared our frustration with trying to find a construction company that instilled any kind of trust. From the moment Trelli answered our call, showed up on time (down to the minute) for our initial meeting, listened with interest, shared ideas passionately and seems genuinely excited to do the project… we knew we found the right team. The project took as long as they said it would. The overall price was higher than discussed but only because of the additional things we decided to do mid course. Minor mistakes happened but immediately rectified by Trelli and at their own expense. The team is very professional, skilled and they deliver what they promise! They were readily there to discuss things, clarify and also for emotional support. When you are spending that kind of money, sometimes you get overwhelmed. Trelli was there to talk us through it, reassure and instil confidence. How many contractors do you know who would do that?!?! Not many. We checked. It took us 5 years of searching to find the right ones. Are they the cheapest? No, but you get what you pay for. Ease of mind, transparency and complete competence. We have zero regrets and have recommend them to all our friends. Thank you, Trelli, we absolutely love our new home!

We hired Trelli for our home renovation project which consisted of redoing almost the entire main floor of our Bungalow home. This included kitchen, stairs, floors.
We were very happy with Trelli’s work and service. All the workers who came to our house were great: competent, friendly, helpful. Brad and Gio are absolutely amazing to work with !
Andrew and Mike’s project management service was oustanding. Anything that came up, they dealt with immediately. They made the whole experience seamless!
The project came in on Budget and Andrew was very good at keeping us updated on costs.
This was overall a great experience and we highly recommend Trelli!

We recently converted a duplex in the Plateau built in 1900 into a fully renovated single family home with Trelli Construction. We came up against some unexpected structural problems with the property and financial changes on our end, and thankfully, the Trelli team was able to pivot, advise and adapt.
They hold themselves to a high standard of quality and it is reflected in the caliber of the materials they use and the installation and execution of the work. Not only was the work well done, every person we interacted with on their team was friendly and respectful.
Listen, here's the T: renovations are extremely stressful and there will always be delays and unexpected issues that arise. With Trelli, I felt we were in good hands and even though I was stressed and there were delays, I took comfort in the open communication I had with Andrew and Mike, and in knowing that the work was being well done so future problems could be avoided. The end result is a beautiful, structurally sound, well build and well designed home that we are so happy with!
Thank you Andrew, Mike, MStudio and the entire Trelli team??
