"It was a complex project. They were very careful with their procedures and raised sunken concrete sections next to the house and around a pool to allow for drainage. They filled the major cracks. They were courteous and on-time over several days. After many years the water in the basement problem has been resolved."

"Matt and his crew of Jacob and Christian went far above anything I expected. I called Matt on Saturday afternoon because my sump pump broke and basement had water everywhere. Within 5 minutes of submitting request for a quote he called. Within 30 minutes he was here assessing. Within an hour he had dryers and dehumidifiers set up. He called to check in on Sunday and was here Monday morning. Tuesday morning Jacob and Christian arrived and emptied everything that was damaged by water (and more). They filled a giant dump truck. They were so polite and careful. Right down to the sweeping! I felt like I was dealing with service the way it was years ago. I could not have asked for anything more."

"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!!"

"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."

Basement Waterproofing questions, answered by experts

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

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.
