I had Lagois do some renovations on my home and was blown away with the work. The workmanship looks like something you would see on TV. Second to none. The job was done quickly and on budget. I could not complain about any aspect of the job. Definitely recommend Lagois to anyone looking for drawings or renovations!

We are delighted that we made the finals. And we are even more delighted with the wonderful home that Herb and your firm have designed and shepherded us through all of the bureaucratic hurdles necessary to get it built. We love living in the spaces you have created for us. So many thanks!

We are writing this letter to thank your company and team of professionals for the outstanding design and construction of our three season room and deck addition to our home last fall. Taking a homeowner’s ideas and translating them into tangible drawings to create a beautiful and well-designed project clearly represents one of your firm’s greatest strengths. Your team’s ability to plan and construct a well-built atheistically pleasing and functional addition that seamlessly integrated into the existing look and feel of our home exceeded our expectations…

When the work was finished, Herb again showed up to do his final review of the work with us, at this point my wife made a statement that “Herb is the Mike Holmes of Ottawa”, and I fully agree with her. Herb made this issue just go away with minimal stress on us.

Herb Lagois and his staff helped my wife and I achieve our dream retirement home/B and B more than the architect we had worked with for 6 months. Supportive, thorough, and always professional, their product was recognized by Ottawa Home Builders with an award for Barrier-free design. The photos at www.323Wallace.com speak volumes about their work.

We were extremely pleased with the entire process, from quoting through to the final walk-through. Herb and his team (Sophie, Chris, Tom, Andrew, Jim – and more!) were super to deal with. They listened to our ideas, asked thoughtful questions, and were receptive to our responses, even when we might not have gone with their suggestion. There were no major problems; and all minor problems were addressed promptly. All my questions were answered within 24 hours – often sooner. Someone was available on site pretty well every day and we had weekly meetings to address decisions that needed to be made

We had Lagois do an extensive interior renovation for us in 2008. When we were ready to tackle an exterior renovation in 2014 we went straight back to Lagois. We did not consider another designer/contractor since we had been so pleased with the quality results and focus on customer service in the first project. We knew from experience that Lagois truly wants to make the customer happy as they are always ready to listen to any concerns and find a solution.

10 years later we consider the project successful and a pleasant experience. The occasional subsequent contact on other matters they remain helpful and a pleasure to work with.

I have had the pleasure of using the services of Lagois Design Build on several occasions over the past 15 years. 2 jobs in particular stand out, a complete basement renovation and a kitchen, family room and living room renovation. This involved new hardwood floors, trim, shelving units and a new gas fireplace installation with mantle etc. I have always found the staff to be very polite and professional, the quality of the work has been excellent. Herb and his staff are very innovative and have excellent ideas for various situations. I have no hesitation in recommending and using Lagois Design Build for future work.”

We are extremely pleased with the work that Lagois’ team did. The workers were excellent and as my husband and I were both working, they had the run of the house and did not mind our three dogs and the cat.

Once again, I am at a loss for words to adequately thank you Herb, Connie and everyone at the Lagois office for a wonderful day of golf. The money raised from this year’s tournament is going into installing a new floor in the kitchen that is badly in need of replacement. Truly Lagois Drafting and Construction is leaving it’s mark on the House!

On Behalf of the Children’s Hospital of Eastern Ontario and the Ottawa Chapter of The Compassionate Friends, I want to thank you for your generosity in helping construct “the arbour”. This beautiful arbour marks the entrance of the Butterfly Garden, a special place for families to honour children of all ages who died. Your kind contribution had made such a difference and will be honoured by family and friends for many years…
