"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 workers were outrageously good. The guy that did the estimate was under what it should have been and it cost us double the amount, but the guys who did the work were fabulous and made it work. It cost more, but the basement does not have a smell or anything, so I can't blame them for it. They were done in a week. I was embarrassed, there wasn't a speck of dirt when they were done. It was clean as a whistle, and it wasn't like that when they walked in. They were really good. They recommended an electrician, and so even if they didn't do some part, they support you and help you find them. They check up and make sure everything is okay. They call back every time you call them. They did a great job."

Basement Waterproofing questions, 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.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.
