"Based on the foundation being brick, there was not the option to add weeps. Additionally in the middle of February, I did not want to excavate the exterior. Therefore the waterproofing was done from the inside. Renew added a rigid board covering onto the foundation interior which will direct moisture downwards to the new drain tile system and now the basement is humidity and moisture free. Very pleasant folks to work with too."

"I contacted Accurate Basement Repair after my basement decided to spring a leak this spring. If Iâ m going to be honest, itâ s happened before, but not to the extent that it did this year. Iâ ve held off calling anyone out of fear of how expensive basement repairs can be and I was expecting the worst. Accurate was recommended to me by my mother and by another friend of mine. I called to schedule an estimate and the woman I spoke with was great. A few days later, John came out to my house to inspect my basement. He walked around and looked at everything inside and out. John recommended to do a drain tile test because although I had water coming in thru some cracks in the wall, I was not getting any water in the sump crock. He explained the process to me so I knew exactly what to expect. If youâ re curious on how respectful Accurate will be to your property, John did not want to cut into the carpet in my basement, he wanted to roll it back so it wasnâ t damaged.... I cut the carpet myself. Afterwards he wouldâ ve tried to fix the carpet I cut if I hadnâ t told him not to bother. After the drain tile test was completed, John explained the results to me in such a way that I understood. While my basement may need corrective repairs in the future, John made several recommendations for outside work that he suggested that I try first. If those donâ t work, he said I should do the corrective interior work. It wouldâ ve been really easy for John and Accurate Basement Repair to sell me a completely new drain tile installation to correct the issues I was experiencing with my home and I would not have bat an eye at it. If youâ re looking for a repair company that is trustworthy and honest, you donâ t have to look any further than Accurate. If the exterior repairs donâ t do the trick at my house, I will not have anyone else but Accurate do the interior repairs."

"Just a super positive experience overall. We were always kept in the loop on what progress was going to be made in the coming day or week. The workers became friends we looked forward to every day. They turned our sad dungeon basement into a light and beautiful and airy and cozy space we actually want to go spend time in with our tiny kiddos. =)"

"First, Bob [Provider Name Removed] took the time to explain all aspects of what is causing the mold in our crawl space. His explanation was consistent with the mold testing specialist/microbiologist we hired. The options for turning our crawl space into a mini basement were in-line with what our microbiologist said. The installation team was great to work with. They were very knowledgeable, professional, and respectful of our property. They cleaned up all the post project debris too. We are very happy with our fully enclosed crawl space that doubles as lock-and-key storage. We highly recommend the entire Basement Repair Specialists team."

Basement Waterproofing FAQs, answered by experts

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

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.

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

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.
