"Groundworksâ listened to our input and throughly evaluated the requirements to support the basement walls and prevent water from coming in. They were on time and communicated clearly and timely. The Foreman did an evaluation and recommended a couple changes to the plan that I agreed with and weâ re beneficial. The 3 workers knew what they were doing and worked hard. I appreciate the manner they communicated and they were very friendly. Overall, they did a great job!"

"Wow I got a pro when I hired Kevin from KJ Drywall to waterproof my basement. Not only did they do an excellent job but went beyond what they contracted to do. I recommended them to neighbors and KJ (Kevin) treated them in the same professional and efficient manner. Highly recommend KJ Drywall."

Basement Waterproofing questions, answered by experts

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.
