"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

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.
