"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."

"I contacted them for an evaluation and estimate. The person who came was friendly, knowledgeable and honest. He didn't think I needed the work, just a handyman to fix a very small leak from the patio, which we ended doing ourselves. I greatly appreciated his honesty. So I don't know about their work but the inspector they sent was great."

Basement Waterproofing FAQs, answered by experts

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.
