"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

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.
