"The price I paid was phenomenal when you weigh the peace of mind I got! Every time it rained all I could think about was whether or not my basement was flooding if I wasn’t home! Ever since Phil and the basement experts were there I have had no further issues! Highly recommend them!!!"

"It has now been a year since we had the waterproofing of our basement waterproofed. I waited this long because with this type of repair I believe you have to wait and see if it did what it was supposed to do. Of course we have had a very dry summer but we have had several heavy rains when it did rain. Please note that the customer service is rated very low: this is only because I have no idea what it is like and no reflection on the actual company in that respect. So hear is what I think: First and for most our basement has stayed dry. However, we had a footer that they replaced all around the base of the walls. We did everything we were told to do and yet there are still numerous cracks in it. My concern is that these cracks will allow the concrete to break. We paid $20000.00 for this fix and now have cracks. Was it worth it? Well we are dry so that's good, but for the money I am very disappointed to see all the cracks! This survey gave me no way to give the answer for post work so all I can go on is pre. The flaw in this is that I can only comment on when they were trying to sell the product to me. I found the salesmen was somewhat arrogant and pushy. We went with this company because we only had 1 other prospect (who we would have gone with, by the way, but despite what the salesman from Mid Atlantic would have you believe, offered the same warranty but wasn't able to get to us in time and we needed the work done)."

Basement Waterproofing FAQs, answered by experts

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.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.
