Who we are

-Owned by 4 brothers and 1 sister, Pool Builders Ltd. is truly a family-owned and operated business. The Grandmaison family has been installing pools for 3 generations. Retired company founder, Bob Grandmaison, continues to pass down his expertise and industry knowledge to the current generation. We install on average 70 in-ground vinyl pools every season, and we have been doing so for over 45 years. Since 1971, Pool Builders Ltd. has installed just over 2,500 in-ground vinyl swimming pools.

-Although we are Ottawa’s biggest vinyl liner in-ground pool installer our team is only made up of 15 to 18 people. Of this, five are company owners who each actively run a company department. Our systematic and organized approach is what allows us to install so many pools per season while still upholding our core company values of quality, professionalism, and integrity.

-Pool Builders Ltd. is very proud of the excellent reputation we’ve earned over the years. We have countless glowing reviews on numerous social media platforms. Not only are we recognized locally but also on the national scale through the Pool & Hot Tub Council of Canada’s Design and Construction Awards. Since 2017, Pool Builders Ltd. has been an award-winning company. Our most recent accomplishment was bringing home both a gold and silver award in the national 2022 Design and Construction Awards.
