Water intrusion can damage foundations, basement walls, flooring, insulation, framing, stored belongings, and indoor air quality. Damp walls, musty odors, peeling paint, white mineral deposits, and water collecting after heavy rain are all signs that moisture is entering the property. At On Top Masonry & Construction, we provide professional waterproofing services in New Rochelle, New York, helping homeowners and property managers control water, protect masonry, and reduce the risk of recurring basement damage.
New Rochelle properties face a combination of heavy rainfall, seasonal snow, coastal humidity, aging foundations, changing soil conditions, and drainage challenges. Homes closer to Long Island Sound may experience additional moisture exposure, while older properties may have limited or deteriorated waterproofing systems.
Our team provides exterior foundation waterproofing, basement waterproofing, crack repair, masonry sealing, drainage improvements, French drain solutions, sump pump coordination, foundation coatings, and water-damaged masonry repair. We begin by identifying how and where water is entering before recommending a practical solution.
Waterproofing is not a single product or coating. Effective moisture control often requires a combination of repairs, drainage, sealing, and water management.
Our waterproofing services include
The recommended system depends on the source of the water, the foundation material, property grading, drainage, and the severity of the problem.
Below is an overview of the premium services we offer to homeowners across New Rochelle, NY.
Basements are vulnerable to moisture because they sit below ground level and are surrounded by soil. Water may enter through wall cracks, floor joints, porous masonry, window wells, utility penetrations, or pressure beneath the floor. Common basement waterproofing concerns include: Water after heavy rain Damp basement walls Wet floors Musty odors Mold or mildew Peeling paint White powdery deposits Water around wall-floor joints Moisture near basement windows Cracked foundation walls We inspect the basement and exterior conditions to determine whether interior drainage, exterior waterproofing, crack repair, sump pump installation, or a combined system is appropriate.
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.
Cracks are common water entry points. Even a narrow crack may allow moisture into the basement during heavy rain or snowmelt. We repair and seal: Vertical cracks Diagonal cracks Stair-step masonry cracks Cracks around windows Cracks near utility penetrations Wall-floor joint openings Cracks in concrete block walls Leaking foundation corners The correct repair depends on whether the crack is caused by shrinkage, settlement, soil pressure, or structural movement.
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.
Several local conditions can contribute to water intrusion.
Intense rain can overwhelm gutters, soil drainage, window wells, and aging waterproofing systems.
Humidity near Long Island Sound can contribute to damp masonry and elevated basement moisture.
Water enters cracks, freezes, expands, and gradually creates larger openings.
Older homes may have deteriorated mortar, porous blockwork, limited drainage, or outdated waterproof coatings.
Soil that slopes toward the house directs surface water against basement walls.
Groundwater can push against foundation walls and beneath basement floors.
Joints between walls, floors, additions, and utility openings can become vulnerable over time.
Consider arranging an inspection if you notice
Early action can help prevent more extensive damage to finishes, framing, masonry, and stored items.
We provide waterproofing services throughout
We also serve surrounding Westchester County communities.
Many homes throughout New Rochelle were built decades ago using traditional masonry and concrete foundations. Although these structures are durable, years of exposure to moisture gradually weaken waterproof barriers and mortar joints.
Professional waterproofing helps reduce these risks while protecting your investment.
Moisture problems rarely resolve themselves. As water continues entering the foundation, it may gradually weaken concrete, masonry, insulation, flooring, and framing.
Early waterproofing helps prevent these long-term issues.
Every project begins with a detailed consultation and inspection.

Exterior waterproofing stops water before it enters the wall, while interior systems collect and manage water that reaches the basement. The better option depends on the property and source of the leak.
Yes. Foundation cracks can be repaired and sealed, but drainage or exterior waterproofing may also be needed if water pressure is causing the leak.
A sump pump may be recommended when an interior drainage system collects groundwater or when the property has a history of basement flooding.
