"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, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

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.
