Crawl Space Encapsulation in Yonkers
Crawl space encapsulation involves sealing the crawl space entirely with heavy-duty vapor barriers and often includes a dehumidifier. This not only waterproofs the walls but also controls humidity, stopping mold growth and wood rot in the crawl space. Humid summers bring condensation on cold pipes and toilet tanks, which can drip onto ceilings and floors below. An encapsulated crawl space can significantly improve indoor air quality and energy efficiency by keeping moisture from moving up into the home. We use durable, reinforced poly sheeting for walls and floors, sealed at all seams and penetrations.

Waterproofing Costs vs. Repeat Water Damage in Yonkers, NY
Waterproofing a shower or wall costs far less than repeated drywall, cabinet and flooring repairs. Ignoring moisture also invites mold, which can be expensive to remediate. A typical shower wall waterproofing project falls in the low thousands, while exterior block sealing varies with wall size. We give you a written quote so you can compare options clearly.
Plumbing Leak Behind Walls in Yonkers
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We find the leak with moisture meters, thermal imaging and pressure tests. The damaged section of pipe or valve is replaced, and wet drywall is cut out and dried. Once the cavity is dry, we restore the wall and seal any wet-area walls.
Exterior Foundation Waterproofing in Yonkers
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most reliable method for preventing water from entering the basement or crawl space. We use high-quality asphalt-modified polyurethane membranes or polymer-based coatings that resist hydrostatic pressure and soil movement. Much of New York sits on glacial till, rock and clay, which makes excavation for sewer and water lines slower and more involved. Proper drainage solutions, such as French drains, are also added to divert water away.
Drainage System Integration in Yonkers, NY
Lasting walls waterproofing often requires a solid drainage system to divert water away from your foundation. This can include interior perimeter drains that channel water to a sump pump, or exterior French drains that collect surface water. Our team designs and installs custom drainage solutions for Yonkers, NY properties, so water is efficiently managed and moved away from your home's vulnerable areas.
Exterior Block Wall Waterproofing in Yonkers, NY
Block and stem walls often show efflorescence, which is the white mineral crust left when water passes through masonry. Irrigation and sprinklers aimed at the house are common culprits. We adjust or reroute irrigation, clean the wall and apply a breathable masonry sealer or elastomeric coating. Proper grading and drip line placement help keep the wall dry.
Foundation Crack Repair & Sealing in Yonkers
Even minor cracks in foundation walls can allow serious water intrusion. Our services include crack repair using epoxy or polyurethane injection to seal these entry points permanently. This method fills the entire depth of the crack, restoring strength and preventing water penetration. We address both vertical and horizontal cracks, knowing that horizontal cracks can signal structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and expensive future repairs.

Below-Grade and Basement Wall Waterproofing in Yonkers
New York has some of the oldest housing in the country, and many homes still have galvanized steel supply pipes and cast iron drains. Wherever a home has a basement or below-grade walls, heavy rain and snowmelt can push water through foundation walls and cracks. We seal cracks with injection products, apply interior or exterior waterproofing and install drainage where needed. A sump pump may be added if groundwater collects.

Damp proofing is a less durable solution, typically a spray-on asphalt coating that resists soil moisture but isn't designed to withstand hydrostatic pressure. Waterproofing uses stronger membranes, coatings, or drainage systems built to prevent liquid water from entering, even under pressure. For basements or crawl spaces in areas with high water tables or heavy rainfall, waterproofing is essential.
HCL Plumbing works with trusted manufacturers known for high-quality waterproofing products. We commonly use products from brands like Xypex, Tremco, and Sika for their proven effectiveness and durability, from crystalline admixtures to elastomeric membranes and sealants.
