"⭐⭐⭐⭐⭐ 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!"

"In all my years of hiring various contractors for work done on my own place, as well as for work done at some properites I managed for many years, (30)I have never had such excellent work done by any conractor. Not only did All Dry Basement honor their written estimate, they went beyond several times on other things not covered, but related. This was all done in Covid times. All workers were always unfailingly polite, respectful, neat, organized, prompt etc. Fill in the words of your choice for attributes that you would look for in a contactor, and you have a picture of All Dry basement people."

Basement Waterproofing FAQs, answered by experts

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.
