"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!"

"I'm very dissatisfied with this company as a whole. After giving my deposit, I was told they would be to my home on a set date and time. They didn't show up on set date and didn't call or text as to why no one showed up. After calling several times, the next day someone calls apologizing profusely but gave no reason as to why the workers didn't show up. When you finally get them to come, they start the project and then the cat and mouse games begin! They'll call and say they have to finish another project and would be there a little later and then call back because that other project ran longer than expected. It's now 4 months into what I was told would be no more than a week! Calling the company itself about what's going on or complain is absolutely impossible, if someone does answer the phone, they give you the run around. Parts of my electrical was messed up by their worker, I was told that they would take care of it right away. Lies, lies and more lies with this company!"

"I complained twice and they had to come back out twice because they didn't apply the insulation as thick as I paid for. I assume because they were angry about coming back out they covered up two of my vents so I can't attach the pipes to them. I can't even find the ends. I will need to dig the expensive foam out to find them."

Basement Waterproofing questions, answered by experts

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.
