Water damage is one of the most common and costly problems homeowners face. Whether it’s a damp basement, foundation seepage, cracked walls, or recurring flooding after heavy rain, moisture can gradually weaken your home’s structure and create unhealthy living conditions. At On Top Masonry & Construction, we provide professional waterproofing services in Yonkers, NY, helping homeowners protect their foundations, basements, crawl spaces, and masonry from long-term water damage.
Yonkers experiences significant rainfall, snow, ice, and freeze-thaw cycles throughout the year. Combined with aging foundations and changing soil conditions, these weather patterns can allow water to penetrate below-grade walls and foundations. Left untreated, moisture intrusion can lead to mold growth, structural deterioration, foundation movement, and expensive repairs.
Our waterproofing solutions are designed to stop water at its source while protecting your property for years to come.
Every property experiences moisture differently. That’s why we provide customized waterproofing solutions based on your home’s construction, drainage, and foundation condition.
Our waterproofing services include
We carefully inspect your property before recommending the most effective waterproofing solution.
Below is an overview of the premium services we offer to homeowners across Yonkers, NY.
Basements are naturally vulnerable because they sit below ground level. When surrounding soil becomes saturated, water pressure builds against foundation walls and basement floors. Our basement waterproofing services help prevent: Basement leaks Water seepage Damp walls Mold growth Musty odors Floor damage Foundation deterioration We use proven waterproofing methods to keep your basement dry while protecting the structure above.
Your foundation is constantly exposed to moisture from surrounding soil. Waterproofing helps create a protective barrier that reduces water penetration and prolongs the life of the foundation. Foundation waterproofing may include: Exterior waterproof membranes Crack sealing Waterproof coatings Drainage improvements Foundation sealing Moisture protection systems Waterproofing is especially beneficial for older homes where original waterproof barriers have deteriorated over time.
Not every foundation crack is structural, but every crack has the potential to allow water into the home. We repair: Vertical cracks Horizontal cracks Settlement cracks Shrinkage cracks Basement wall cracks Concrete cracks Masonry cracks Repairing cracks early helps prevent larger structural issues while reducing moisture intrusion.
When groundwater enters the basement, an interior drainage system can help collect and redirect water before it reaches finished living areas. Interior waterproofing systems may include: Drainage channels Perimeter drains Collection systems Moisture management Water diversion Integration with sump pumps These systems work together to remove water efficiently while protecting the basement floor and foundation.
French drains help move water away from your home before it reaches the foundation. Benefits include: Reduced hydrostatic pressure Better drainage Less standing water Protection against foundation movement Improved landscape drainage Reduced basement moisture Proper grading and drainage are essential parts of any waterproofing project.
For homes that experience recurring basement water, a sump pump provides active protection by collecting groundwater and pumping it safely away from the property. We install: Primary sump pumps Battery backup systems New sump pits Replacement pumps Discharge lines Complete sump pump systems A sump pump is often the final layer of protection in a complete waterproofing system.
Many crawl spaces suffer from excess humidity and moisture because they are rarely ventilated properly. We help protect crawl spaces by installing: Vapor barriers Drainage systems Moisture barriers Waterproof coatings Crack sealing Drainage improvements A dry crawl space contributes to healthier indoor air and helps prevent wood rot and mold growth.
