Foundation Crack Repair in Lancaster
Even small cracks in your foundation walls can allow water to seep into your basement or crawl space. Our walls waterproofing service includes foundation crack repair using proven epoxy or polyurethane injection techniques. These materials fill and seal cracks, preventing future water entry and often strengthening the foundation. Addressing cracks promptly in Lancaster homes is crucial to avoid larger, more costly structural issues.
Plumbing Leak Behind Walls in Lancaster
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We locate 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 surfaces.
Interior Walls Waterproofing in Lancaster, PA
Interior walls waterproofing focuses on managing water that has already passed through the foundation walls. This typically involves installing an interior drainage system, often called a French drain, along the perimeter of the basement floor. Water is collected and channeled to a sump pump, which then sends it safely away from the foundation. While not preventing water from entering the wall, it effectively stops it from pooling inside your living space. This solution is less disruptive than exterior excavation and works well where exterior access is limited.
Exterior Foundation Waterproofing in Lancaster
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most effective 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. Rocky, clay-heavy soils are common in Pennsylvania, which can make sewer and water line excavation more involved. Proper drainage solutions, such as French drains, are also added to divert water away.
Below-Grade and Basement Wall Waterproofing in Lancaster
Pennsylvania has some of the oldest housing in the country, including rowhomes and farmhouses with galvanized supply lines 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.
Exterior Block Wall Waterproofing in Lancaster, PA
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 Lancaster
Even minor cracks in foundation walls can allow significant 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 indicate structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and expensive future repairs.

Frequently Asked Questions About Walls Waterproofing in Lancaster
The cost of walls waterproofing in Lancaster, PA can vary a great deal based on the method used, the extent of the damage, and the size of your foundation. Basic crack sealing might range from $300 to $800 per crack, while a full exterior foundation waterproofing project could be $8,000 to $20,000 or more. Interior drainage systems with a sump pump typically fall between $4,000 and $12,000. We provide transparent, itemized quotes after a thorough inspection.
For extensive walls waterproofing projects that involve excavation, major structural changes, or changes to drainage systems, a permit from the Lancaster building department may be required. We will advise you on any required permits and help with the application process so all work complies with local codes.
Walls waterproofing is generally not recommended as a DIY project due to its complexity and the critical importance of a sound foundation. It often involves heavy excavation, specialized equipment, precise material application, and knowledge of drainage principles and local building codes. Improper waterproofing can lead to more severe and costly damage down the line, so professional help is highly advisable.
When professionally installed using high-quality materials, walls waterproofing can last for many decades, often 20 to 50 years or even longer. The lifespan depends on the materials used, the quality of installation, and environmental factors like soil movement and water exposure. Modern membranes and sealants are designed for long-term durability.
While minor DIY fixes like patching small cracks are possible, complete walls waterproofing is best left to professionals. It involves specialized knowledge of drainage, foundation mechanics, and proper material application. Improper DIY work can lead to ineffective results, wasted money, and worse water damage over time.
Interior waterproofing addresses water after it has entered the foundation, typically managing it with sealants and drainage systems inside the basement or crawl space. Exterior waterproofing prevents water from reaching the foundation walls in the first place, usually by excavating and applying membranes or coatings to the outside of the foundation.
Waterproofing prevents the moisture mold needs to grow. Existing mold should be removed and the area dried before sealing. We remove affected materials when needed and recommend remediation for larger growth.
We use a range of high-performance waterproofing membranes and coatings depending on the application and foundation type. These can include liquid asphalt-modified polyurethane, rubberized asphalt membranes, bentonite clay systems, and crystalline coatings. Brands often include well-known names known for their durability and effectiveness in preventing water penetration.
