"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."

Basement Waterproofing FAQs, answered by experts

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
