Laundry Room and Utility Wall Waterproofing in Alexandria, VA
Washing machine hoses, utility sinks and water heaters can all leak into nearby walls. We replace burst-prone rubber hoses with braided stainless hoses and install leak pans and shutoff valves. Walls around water heaters and laundry boxes can be sealed to resist water damage. These small upgrades head off costly drywall repairs.

Exterior Block Wall Waterproofing in Alexandria, VA
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 frequent 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.
Exterior Foundation Waterproofing in Alexandria
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. Basements are common in northern and western parts of Virginia, while crawlspaces and slabs are more typical in the east and south. Proper drainage solutions, such as French drains, are also added to divert water away.
Sump Pump Installation and Repair in Alexandria, VA
Sump pumps are a key part of many interior waterproofing systems, particularly in homes that see heavy rainfall. We install high-capacity sump pumps designed to handle large volumes of water, keeping your basement dry even during flash floods. Our services include primary sump pump installation, battery backup sump pump systems for power outages, and routine maintenance or repair of existing units. We make sure the discharge line is routed properly so water does not circulate back toward the foundation.
Below-Grade and Basement Wall Waterproofing in Alexandria
Many homes built from the late 1970s into the 1990s used gray polybutylene supply lines, a material known for leaks and sudden failure. 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 builds up.
Commercial Walls Waterproofing in Alexandria
Beyond residential properties, FBN Plumbing also offers walls waterproofing services for commercial buildings in Alexandria. Protecting commercial basements, equipment rooms, and underground parking garages from water damage is essential to business operations.

Waterproofing Costs vs. Repeat Water Damage in Alexandria, VA
Waterproofing a shower or wall costs much less than repeated drywall, cabinet and flooring repairs. Ignoring moisture also invites mold, which can be expensive to remediate.

Frequently Asked Questions About Walls Waterproofing in Alexandria
The cost of walls waterproofing in Alexandria, VA 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 usually fall between $4,000 and $12,000. We provide transparent, itemized quotes after a thorough inspection.
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 heavier growth.
Key signs you need walls waterproofing include damp or wet basement walls, visible mold or mildew growth, a musty odor in your basement or crawl space, efflorescence on concrete walls, cracks in the foundation, or standing water after heavy rains. Don't ignore these warning signs, as they often point to ongoing water intrusion.
Yes, FBN Plumbing stands behind the quality of our walls waterproofing services. We offer full warranties on our materials and workmanship, giving you peace of mind. Warranty details will be provided with your project proposal, spelling out the coverage and duration of your waterproofing system.
Walls waterproofing is a key step in preventing future mold growth by eliminating the moisture source. However, it does not remove existing mold. If mold is already present, it will need to be professionally remediated before or along with the waterproofing process. Once the area is dry and mold-free, waterproofing will help make sure it stays that way.
While minor DIY fixes like patching small cracks are possible, full 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.
The duration of a walls waterproofing project varies depending on its scope. Minor crack repairs might take a few hours, while an interior drainage system could take 1 to 3 days. A full exterior foundation waterproofing project, involving excavation around the entire home, could take 3 to 7 days or more. We provide a clear timeline during our initial consultation.
Walls waterproofing is generally not recommended as a DIY project due to its complexity and the high 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 the smart choice.

A pipe burst at 11 pm and they actually answered. The plumber showed up within the hour, shut everything down, and had us back to normal the next morning. Could not ask for more.
