The sump pumps installed by the builder in our 'almost' three year old home were struggling to pump out the water from the last heavy rains we had. We had a possible extreme flood situation with our water trap just outside our recessed driveway overflowing with the rain water and had it rained one more minute, my garage would have been flooded. One of the sumps was actually submerged in water in the tank. Flavio assessed the pumps and determined they were not strong enough to pump out the amount of water we get because of the driveway grade and the sumps were not intended to be submerged as they were. Bottom line, the install could cause a possible electrocution concern! He replaced them with submersible ones that could take on the amount of water and suggested a few more improvements to consider. I felt I received excellent personable service! Flavio is very BUSY!!! but he really stepped up to the plate to get the job done and done right and kept me informed throughout the process. I would highly recommended him and already have to two of my neighbours. I will most-certainly use him again.
