"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!"

"Everyone we dealt with from Cantey Foundation Specialists were very professional, timely, and caring throughout the entire process from job estimate to the actual work done. While the work done did not bring all areas back completely to their original states, with the exception of one area, they were all pretty close. Realistically, It's very difficult to fix in two days what has taken place over a period of years. I am very satisfied with the job done. Grayson (job estimator) and Estevan (crew leader) were very helpful and great to work with through the entire process."

This is just one of the foundation cracks we found on this foundation. It's what we call a stair-step crack.

Basement Waterproofing FAQs, answered by experts

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
