"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!"

We're a refreshingly different kind of company. We take a "whole house" approach to find the best, most efficient energy savings in your home or small business. Focused on quality, "energy saving" spray foam, insulation, and weatherization, we act as a consultant and gateway to your largest energy savings.

"We hired Performance Energy to air seal our attic and add additional insulation. Their representative provided a clear explanation of their process and provided a thorough assessment of our home's energy concerns. I had already done a lot to the house, so I was pleased to have a second set of eyes evaluating my work. They arrived with a crew of four, three were in the attic for several hours sealing all the gaps and cracks between the attic and the living space. They also used a thermal camera to check for leaks in my HVAC ductwork that was in the attic - prior to insulating. Once all the sealing was complete, they proceeded to add additional insulation throughout the attic. The only snafu was their generator died. We looked at the electrical connections and found the brushes in the motor had overheated and melted. It took about an hour to get a replacement generator and they were able to finish the project. Other than the generator - things went smoothly. I would definitely recommend them if you want to make your house more energy efficient. Don't add extra insulation until you have air-sealed!!"

Basement Waterproofing questions, answered by experts

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

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.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.
