"The team, led by Trevor, and assisted by Kenny, Terrell and Garrett, worked very well together to accomplish the work we needed done to alleviate water coming into our crawlspace. They were courteous, friendly, professional, and did not hesitate to answer all our questions and explain the process thoroughly. Trevor and team brought other problems to our attention which we have decided to have Mount Valley repair also. Trevor and Shawn helped us get the process going to replace floor joist damaged by water. I would recommend Mount Valley if you have foundation issues that need expert repairs!"

"Called him on a Monday and the job was done by Thursday. Courteous and honest. Used his $425 roof inspection plan. Inspected my whole roof along with the repair work I needed. Buttoned up some siding issues that we also needed. Got the job done for way less than I thought it would be."

Basement Waterproofing questions, answered by experts

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.
