"Absolute waterproofing did an outstanding job installing carbon straps on a bowed basement wall. Not only did they do a great job , Lou took care of tbe township permit application and follow up . He was always available to answer any questions, supply information and warranty on carbon straps! When we decided to hzve the basement painted he got his crew together to do it immediately. He did an outstanding job. He was thorough, Always accessible and returned phone calls, explaining everything that he was doing to fix the problem! I highly recommend Absolute Waterproofing for any House that has a basement issue ! Barbara kenas remax central"

"I can't say enough good things about American A-1 Waterproofing. Roland and his team were amazing. I had originally opted to go with another contractor to install a French drain and sump pump, but after exposing the foundation, they got spooked and said they wouldn't perform the work. Roland came by and assured me his team could get the work done and they did not disappoint. Through the initial estimate, permitting, construction and final sign off, Roland and his team were communicative, prompt, clean, and extremely professional. It was an absolute pleasure to work with them!"

"Weather-Tite was recommended to me by a contractor who I trust to evaluate and repair water and moisture issues that I was having in my garage. Bob and his crew did a phenomenal job!! My husband and I are beyond thrilled with the results! They are professional, courteous, and fastidious. Half of my garage is underground, as there is a hill in my front yard leading up to the house. The repair involved excavating dirt along the front of my house next to the garage foundation wall down to the drain pipe, repairing cracks and holes, applying waterproofing and more. The interior wall was cleaned and drylock masonry paint was applied. My landscaping on the outside had to be removed and then put back. They did such a good job that you couldn't even tell it had been moved at all. We also had Bob and his crew complete a second job for us. This involved excavating another trench but in the back of the house along 16 feet of the foundation, replacing a drain pipe and waterproofing. They were at our house for three days. During that time and after we had torrential rain and everything stayed dry!!! I highly recommend Weather-Tite Waterproofing, Inc.!"

"American Eagle is the company I chose after sitting and meeting with many others. The best decision I ever made. If you have ever needed to get estimates on waterproofing your basement you know how confusing it is. The pricing went from $5000. - $15000. I met with the owner of American Eagle himself. Not a salesperson. He was on the job the entire time getting his hands dirty. He and his crew were on time, very courteous & professional. They were thorough and took all precautions as far as containing air quality and protecting my property from damage, dirt, and dust. The job was done right. My husband and I are very pleased with the efficiency, cost & time frame the project took. Thank you American Eagle for making installing a French drain in my basement such an uneventful experience. Done in a day from start to finish. The DellaValles"

Basement Waterproofing questions, answered by experts

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

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.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.
