"From the very first meeting, I had a good feeling about the Lagois team and we decided to choose them for our entire first floor renovations. The process was laid out clearly, and every step of the renovation went smoothly. The design team took an incredible amount of time to truly understand our vision and ensure that the plan we had was the right one for us. [...] We are so happy with our new home! It feels exactly like what we wanted and envisioned. Thanks to the Lagois team, we will enjoy our newly renovated space for many years to come."

Homeowner Review
"We had an excellent experience with Lagois and have high praise for the entire team, from the start of our project to the finish! What we most appreciated was the emphasis on good communication during planning and as we worked through the inevitable hiccups that occur during a renovation. We also appreciated the attention to detail in our project and the follow up after completion."

Homeowner Review
"I've had the pleasure of working with Lagois on three separate projects [...]. From start to finish, every experience with them has been nothing short of exceptional. Their professionalism shines through in every aspect of the process. The team is not only dedicated to robust and thoughtful design, but also to keeping the projects on schedule and within budget, which is something you don't always find with contractors. What really sets Lagois apart is how they make you feel like you are their number one customer, no matter the size of project. They're incredibly responsive, attentive to detail, and go the extra mile to ensure you're happy with every step of the process. [...]"
