Wendy was great, she was able to arrange pool repairs same day so that our liner leak was fixed. Brian and Gord showed up on time and their customer service was on point. Seaway team, you're awesome. It was my first experience with your company but I promise it won't be the last..

I was recommended to Harold at Seaway Pools from a pool equipment supplier. After speaking with Harold, I felt he was quite knowledgeable and had asked him about installing a pool liner. When he did a site visit to provide an estimate, he had recognized the liner that was in my pool from 14 years ago (even though he didn't install the original one). He provided a competitive quote and we chose him to install our liner. We needed to have some work to our pool deck prior to the installation of the liner. Harold had worked around the delays we had with other contractors and his team did a great install
