"⭐⭐⭐⭐⭐ We had Adirondack Basement Systems come to our home to lift our foundation, and we could not have been happier with the experience. Mikey, the foreman, and Justin, the installer, were absolutely fabulous from start to finish. Both were professional, friendly, knowledgeable, and incredibly efficient. They took the time to make sure the job was done right, kept us informed throughout the process, and made what could have been a stressful home repair feel completely manageable. It is so refreshing to have a crew come into your home who clearly takes pride in their work and also genuinely cares about the customer experience. Mikey and Justin represented Adirondack Basement Systems exceptionally well. We would absolutely recommend both of them, as well as Adirondack Basement Systems, to anyone needing foundation or basement work. Five stars all around. Thank you, Mikey and Justin, for such a positive experience!"

"Jason and crew did a great job fixing a leak in my basement. I had tried to have a handyman fix it- not successful! The men had to make a number of visits to complete all the steps done, but did it timely and well. And cleaned up afterwards and put in topsoil and grass seed!"

Basement Waterproofing FAQs, answered by experts

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

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.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.

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.
