"He actually pointed out to me that I needed more insulation over the whole home as over a period of time it packs down. So I let him do the whole home as well as garage that I had originally wanted a quote on."

"Hello, we recently got an evaluation. Dylan was great and knowledgeable. He even found a diagnosis underneath our house about water running that we weren’t aware. He, with his awesome customer service, made us feel comfortable and confident on having him checking around our place to get our estimate done. Thanks s much Dylan and Mount Valley Foundation."

Basement Waterproofing questions, answered by experts

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.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.
