Minimal deposit to schedule, balance paid in full at the end of the job.

"My husband and I were introduced to B-DRY SYSTEMS OF SOUTHERN NY, in 2011. Whenever it rained our basement would get puddles, as the basement is partially below ground level. We were told by an acquaintance, that B-DRY had installed their system in a local firehouse, where flooding was problematic. We called B-DRY and a representative came to our home. He inspected our basement and exterior and went on to explain exactly how their system would be installed in our basement and the equipment that would accompany it. An estimate was given and and soon afterwards, the work and installation began. The workmen were polite and knowledgeable and at the end of completion each day, they left our basement and driveway tidy. Twelve years late, now 2023, our basement system is still operating well. With the most recent rainstorm dumping approximately 7.5” of rain in our area, the system continued to function even after one pump stopped working. The secondary pump (system is set up with two pumps) picked up immediately, without residual problems. We called the company and the same day a technician came and replaced the one pump, checking to make sure that everything was operating well. We cannot offer any complaints. Management stands behind their product! Realize, that the cost we paid in 2011, would not reflect what the same basement system would cost today!!"

"Once again, Jason and his guys came through for us for an emergency situation. I noticed a small amount of mold growing on the ceiling above our shower. To me this was an emergency. Though Jason was fully booked up, he found the time to remove and replace the ceiling, install a new exhaust fan, and do all the associated repairs. As always, his team did the job quickly, were professional and neat. The work was top quality. I recommend Explicit Exteriors without hesitation."

"My initial contact with Leelands was 10 years ago. I really admired the work they had done on my neighbors house. I just couldn't afford slate repair or replacement at the time. The employees were always courteous and patient. Fast forward to May 2018, I had exhausted all the patching my roof could take. I contacted Leelands, Donna promptly scheduled Luke to come out for an estimate. Luke was on time and provided honest feedback. I recieved a Photo Report, Field Condition Report and Proposals a few weeks later. It took me a few more months to decide how to proceed. In October, Leelands sent Gabriel and Miguel to make the repairs. They were prompt, courteous and worked diligently to finish the job. After a rainy 2018, my roof is still leak free."

FAQs for basement waterproofing projects in Grahamsville, NY

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
