2nd time working with Fedor and his team. First time was for some plumbing. This time we lowered our home 2ft (this was in Dec 2017).
Overall the execution was great. They covered up everything before hand, were very cautious from a safety perspective and cleaned up after the job was done. They even repaired minor plumbing that broke over the winter dig. All in all i would def recommend Fedor; however I would be press for assurances on the below 2 points.
I took off 2 point from a planning perspective which I think Aquamaster should have been able to account for.
1) preference was to not have to put in a sewage ejector pump. Was reassurance that the grade of the drain would be ok. Of course after Day 1, they realized the grade wasn't enough to support the needed slope to the back of the house. We had to add a sewage ejector.
2) We wanted to put in a back flow valve. Aquamaster didn't account for the size of the box, which meant a ~15' bump out from the floor we just lowered - so we had to skip the BFV
