TL,DR: We wish we'd never met them. Our story is one of being over-sold on several products that solved one problem, created others, then solved those by creating more problems. When it's all said and done, the cost of trenching out the side of the house to fix the drain tile would have been as expensive as all of the costs of the Basement Systems solution(s) and the multiple re-builds combined.

Our saga began in Fall 2017 when we decided to do something about a minor leak in our basement wall which had previously been patched over with typical basement sealing paint/epoxy. Basement Systems sold us on getting an interior french drain installed along that wall and another wall to the low point in the basement for a new sump pump and sanidry dehumidifier (which failed within a year). We also had a discharge line for the new sump pump ran and a battery backup, which was nothing more than a $1000 expense for a boat battery and simple in-line charger. They completed the work rapidly -- well within their own deadlines. As for the discharge line, that was a different problem.

We pointed out that the sump pump discharge was not level or downhill and that it should not simply end in the middle of our back yard. They came back to make it level, and we also pointed out that the elbow nearest the house leaked every time it discharged (constantly), making the porch it ran along constantly damp...right next to the house. Basement Systems ensured us this was fine since the water wouldn't run from the new pool its creating in the yard, back into the house (no way it could, since the drain pipe has their "Frost Guard" in it). So, we re-finished the basement and crossed our fingers.

We went into March 2018 and immediately had actual flooding in the basement, not just a slight leak that we started with in the fall of 2017. This time from not just the previous installation but also the other side and through the floor, where we discovered a previous owner had taped over a drain (how this was never a problem before must have something to do with now trying to pump water around the house rather than using a drain tile to guide it farther underneath). We called to get that fixed and after a significant amount of arguing, especially about the sump pump drain pool, Basement Systems agreed to fix that entire side of the previous installation at no additional cost but again assured us the sump pump discharge is "correct" (as if any home owner would agree with that). They actually suggested that if we wanted to extend the line, they would do so at no cost as long as they could lay the pipe on the back yard (I kid you not). And at the same time, we had them install the french drain around the rest of the basement walls. This work they also completed quickly. We decided this time to not rebuild our finished basement so we could observe if we were indeed fixed this time.

Spring and summer of 2018 come with a tremendous mosquito problem caused specifically by the sump pump discharge area (right off our deck), which indeed became a pool that in heavy rain would overflow back towards the house, as we predicted. We also still had persistently damp areas inside anywhere they installed a screw into the concrete without also applying a sealing gel (some they did, some they didn't).

Around this same time, Basement Systems calls to see if we're satisfied.

Obviously, we're not, so we had them come out to inspect the situation. They remedied the screws, and stated they would come back to apply a sealant to the leaking sump discharge elbow as well as provide us a quote for running the discharge line all the way to the fence line, which is an easement specifically used for such things.

We never heard from Basement Systems again.

We've now hired another contractor to fix the sump discharge for us, and have since re-re-finished our basement over the fall of 2018.
