"Please see the earlier review (3/12) for context. I wanted to take a moment to share my experience with Mt. Valley Foundation Services regarding our sump pump installation. Overall, the team did an excellent job with both the initial installation and the subsequent repair of the discharge lines, which had come apart over time. They were professional, transparent, and truly seemed to care about the project. The only challenge I encountered was not with Mt. Valley Foundation Services itself, but rather with its parent company, Ground Works. From my experience, Ground Works has acquired many smaller foundation companies across the U.S., and it seems they may be struggling with logistical coordination. The call center they use is not very user-friendly, and I experienced multiple miscommunications and scheduling errors. Unfortunately, this puts Mt. Valley Foundation Services at the mercy of Ground Works' logistical issues. That said, I highly recommend working with Mt. Valley Foundation Services. My advice is to obtain the names and direct contact information of the service team when booking—this makes future communication significantly easier. Once I was able to reach the team directly, they went above and beyond to accommodate my needs. Living in a flood-prone area, I feel confident that the sump pump project they completed will be a tremendous benefit to our home and property. A big thanks to Danny (the manager) and his team for their outstanding work!"

Basement Waterproofing questions, answered by experts

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Depending on the severity, a slab leak can go undetected for months or even years, especially if you don’t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.

Finding water under your sink can throw a wrench in your day, but acting quickly can prevent water damage. Soak up water with a towel, then put a fan or dehumidifier near the open cabinet to dry it as fast as possible. If any mold or mildew has formed, you may need to replace the bottom of the cabinet.
