Aquatech was wonderful right from the first contact to having Richard come out and give us a very complete and detailed quote to the two man crew who were here exactly on time and completed the day hours ahead of time. All the locates were taken care of and within a week of contacting them the job was completed. The workman did a fabulous job and were very respectful of our property. They reviewed the scope of the work before they started and asked if we had any questions. When the work was complete it was difficult to see where they had worked and dug the trench. Everything was tidier than before they started. We are very impressed and in a world where household repair companies can be less than favourable, Aquatech stands head and shoulders above any of them. We would highly recommend this company. We also have a life time transferable warranty too. Bravo. We will definitely be telling all the people we know about our wonderful experience. Thank you.

They gave us several options for repairs as well as prevention that were fairly priced and a quick turnaround time. They executed our chosen plan quickly and did a beautiful job.

EXCELLENT experience. Andrew was the first one to arrive and was extremely kind and helpful. Igor and Basil joined Andrew a few minutes later and all three of them worked very hard and finished this massive job in one day. These are some of the hardest workers I have ever seen. There were no hassles or surprises and Andrew, Igor and Basil were very skilled and courteous. Also, Nico was VERY flexible with our constant changes of plans and was very accommodating and understanding. An excellent experience all around - could not recommend more highly!

Terry was friendly, fair, and transparent on his work and recommendations. Other bidders could have gouged myself on the price but he was honest. He kept costs downs but the quality was still top notch. He treated our family like one of his own without being “fake” to get the job. He’s as genuine and real as they come.

Slava and his crew did a fantastic job of installing piers and raised our sinking front concrete 4 inches. Very courteous, hard working crew! They hand dig as opposed to other companies that wanted to use a backhoe thus, saved our shrubbery and trees. I would highly recommend Aquatech!
