We had Lagois design and undertake an exterior renovation on our 1950s house. The entire process was very smooth starting with the designer quickly getting our style and coming up with an option that met our tastes. The work went very smoothly and the quality of work is very high. Some inevitable issues came up but they were on it right away with no additional costs. I wouldn’t hesitate to work with them again!

We had Lagois design and build an extension to the front of our house and detached garage. The project required some adjustments because of city requirements and the team from Lagois was able to provide us options and keep us informed on the process as things came up. We are very happy with the end product and the way that Lagois worked with us and completed the project with quality and professionalism. We wouldn’t hesitate to rehire or recommend them.

Superb service and delivery from start to finish. They renovated our kitchen by first creating the design and serving as the general contractor for all the contractors they brought in. Some of the renovation work was done by their own staff. They also helped with shopping for all the products and details required. I absolutely love my new kitchen and I highly recommend Lagois to anyone considering hiring them.


Herb Lagois and his team go above and beyond expectations. Their commitment to excellence and desire to deliver a “wow” experience puts them at the top of the class. I have had the opportunity to communicate with most of his team and without exception, they interact at the level you’d expect from a world-class organization. Your dream home will become a reality in their hands!


The Lagois team has been engaged in projects with Ottawa’s Ronald McDonald House for more than 17 years and as recently as last month completed a large kitchen and coffee area renovation at the House. Lagois exemplifies all that is expected of a first-class renovation, design and build firm. Their attention to detail and workmanship is excellent. The entire Lagois team put their hearts into each project which is so evident with Ronald McDonald Houses’ kitchen renovation. They are a pleasure to work with on projects big and small. You can’t go wrong with Lagois!
