"We hired Leal Restoration to clean up water damage on three floors of our house. They came early on a Saturday morning, worked all weekend and finished the job on Monday. This included drying out the area, removing debris, and replacing a ceiling. The work was done efficiently and carefully. Leal turned a disaster area into a clean and back to normal living space in 3 days. Amazing!"

"They did a fantastic job! We have had driving rain since the installation and our basement is bone dry. They came on time, were very polite and I'm very happy with the fast train system they installed."

"Hired them in August to repoint all of the foundation outside and about half inside of the basement (brick repointing) also added some waterproofing and everything looks great and I haven't had any water come in the basement as a result of Ben The Mason and his son's great work. Highly recommend them for any masonry project, we also talked about redoing my front steps which I will follow up with sometime in the near future."

Basement Waterproofing FAQs, answered by experts

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road.
