"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!"

The team worked clean and did a gorgeous job on our crawlspace encapsulation. Alex and his team (Francis & Dedric) were THE BEST. We really had a great experience and are so grateful for their expert work. They're really an impressive team."

"We had a pool installed in July. Now we are creating our outdoor living space. Other than time management its been great working with Bryan. He stays late to get the job completed and his pricing was the best I got out of 7 quotes. I then hired him to install a pump in my backyard and that too has went well. Currently, he is working on my filtration/aggeration issues to stop the rainwater from washing away my backyard. Bryan is always polite and patient to explain our choices and the cost benefits of them. I appreciate his text of photos & website for clairty. He's very thorough and always cleans up after himself. He recently hired an office assistant, so hopefully that will make a huge difference in his scheduled appointments & communication."

"He did an excellent job painting the inside and out side my house, installed a security front storm door and repaired my roof. I would recommend Kevin Wheeler highly to do any of your home repairs. He is just not only a handy man, but a handy man who gets the job done in an adequate time frame and to his customer satisfaction."

Basement Waterproofing FAQs, answered by experts

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

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.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.
