"Great results from waterproofing. Turned my spring flooding anxiety to calm. As humidity rose in summer, I put in a small dehumidifier. Made basement noisy as it struggled to dry and produced a lot of heat. As temperatures rose to about 83 down there and the humidity rose to over 68%, I had same people put in a whole basement commercial-grade dehumidifier. The small unit dropped the humidity to around 50% in less than an hour. Incredible performance and have me peace of mind and peace and quiet downstairs. Temperature dropped gas as well. Weel worth the price to save my most expensive investment."

"The work performed was incredible. AJ and his team are real pros. The cost for all of the work they performed was more than reasonable. AJ came out for an estimate and explained the work he was going to do and gave me options on what different things he could do to help me out. He kept my wife and I in the loop every step of the way during the project. In addition, the crew didn't rush the job. They made sure the job was done right. Before the work was performed our basement would flood very easily when it rained. After the work was performed it rained and the basement was bone dry. This was a huge relief. Not having to mop up water every fifteen minutes was wonderful. Our sump pump doesn't run half as much as it used to. Basically, my wife and I are thrilled with the work performed and highly recommend AJ and his team to anyone

"My basement is dry. After work was completed, I still had water coming through my walls. I called and they came back to put a waterproof/plastic sheet up with tape that tied into the system they installed. We will see how long that lasts but for now the basement is dry. With that being said, everything that was in my basement is ruined. Everything is covered in about an inch of concrete dust. My wife’s inventory for her business is ruined. Our Christmas decorations are ruined. They put up plastic to protect our stuff but that clearly did nothing. Definitely clear out any belongings you want to use in the future and expect an inch of concrete dust when done. Thus, a bit of a mixed review."

"lWell. The basement was a damp dungeon prior to installation. Now, it's dry and usable. We also had a contractor install a new powder room and floor and lots of closets. We can now use the basement for extra living space.

Basement Waterproofing questions, answered by experts

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.
