"I am amending my review after subsequent contact with Basement Systems. Ultimately I am satisfied with the work they finally did, Kathy from the office is very sweet and the work done by Dale was ultimately done although there was much confusion since I was never called or emailed to let me know that the work was complete (it is a weekend property and we were not present- which makes it challenging to schedule with providers). I do wish they did a better job with communication since this was the main issue (not hearing from them when they were not able to come for an appt or not hearing that they were coming to do the job!) I will say that despite my frustration, I do think the work was done well, Dale assessed another concern or ours unrelated to this job, and will be coming back to further assess and provide an estimate if need be, and Dale even closed a garage door that was left open by another service provider which was much appreciated. So I certainly would do business with them again and am pleased with the final outcome. But for the sake of completion, below is my original review.  

Prior review:
Was initially very pleased with prompt initial response and visit from Dale for free estimate. He came on 9/16 as scheduled, was very likable, friendly and informative and spent much of time surveying house and property and providing recommendations as to how to best address leak in basement and buried drainage pipes on the property of our newly purchased home. Was told he would email estimate within week. Dale made such a good impression that I was surprised that I did not receive the estimate within a week. I called 2 weeks later to remind them to provide estimate which should have been my first clue that things would not proceed smoothly.
Had difficulty getting work scheduled which was to be approx 4 hours of labor for 2 men. Not totally their fault as we are weekenders and could only be there for thurs/friday/saturday dates, so I can appreciate that scheduling might be difficult, but still frustrated that work was scheduled for a friday 2 months later. Was called a few hours before appt and told that someone was sick and they could not do job. Was not called back when I asked to reschedule. When I finally reached Kathy who works in the office was told that Dale would come personally the following Monday and do the work himself. Needless to say he never did and I never heard from anyone from the company since then. Wasted nearly 3 months of our time and left at square one. Thanks for nothing. Extremely disappointed with lack of professionalism and surprised that this company has such high ratings."

"While an interior curtain drain system may be applicable for some, I am unconvinced it is for my situation even though 3 out of 4 of the project quotes were for pushing this "Water Management System" which they say is aka "waterproofing" - it is not."

Basement Waterproofing FAQs, answered by experts

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.
