"⭐⭐⭐⭐⭐ 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!"

"We shopped and spoke with many "facade restoration experts" before choosing to work with High Tech and we are so glad we did our research. Shaiful was by far the most knowledgeable contractor we spoke with and made us feel confident that he was capable of solving our issues.  When it was clear that there was no saving our original cornice, he offered up more than one suitable way forward. We decide to let his crew re-create the original piece from stone. The work they did left us with a beautiful and artistic facade the functions well in collecting rain water from the roof. The crew was respectful, clean and on time. They went above and beyond all of our expectations in touching up every minor detail so that the whole front of the house was left looking brand new. We could not be happier. Our home looks better than we could have imagined. I recommend High Tech Construction with no hesitation.

Basement Waterproofing FAQs, answered by experts

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

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.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

While a standard gutter system is widely considered the most effective way to prevent water damage to your home's foundation, several alternatives are available. These options can be used on their own in certain climates or as supplementary protection.

Common alternatives include:

  • Rain Chains: These are decorative chains that hang from the roof's edge, guiding rainwater to the ground.

  • Drip Edges: These metal strips are installed at the edge of the roof to direct water away from the fascia. While often used with gutters, they can be paired with a ground-level solution but are typically not sufficient on their own.

  • Rain Dispersal Systems: These systems work by breaking up the heavy sheet of water flowing off the roof, dispersing it over a wider area.

  • French Drains: This ground-level system uses a perforated pipe in a gravel-filled trench to collect and redirect water runoff away from the house.

  • Drip Paths: Placed directly below the roofline, these paths made of concrete, stone, or other materials prevent soil erosion and guide water away.

It's important to note that some alternatives like rain chains and dispersal systems may not be adequate in regions with heavy rainfall because they don't divert water away from the foundation as effectively as a full gutter system. Ground-based solutions like French drains can be very effective but are often more expensive and can affect your landscaping and curb appeal. Many experts recommend installing a full gutter system for maximum protection and using alternatives as supplementary measures.

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.
