Sump Pump Installation and Repair in Portsmouth, VA
Sump pumps are a critical 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.

Exterior Foundation Waterproofing in Portsmouth
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. 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 integrated to divert water away.
Foundation Crack Repair & Sealing in Portsmouth
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 for good. 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 costly future repairs.
Crawl Space Encapsulation in Portsmouth
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, preventing mold growth and wood rot in the crawl space. Summer humidity leads to condensation on cold water lines and in crawlspaces, which can speed up corrosion and invite mold. An encapsulated crawl space can noticeably 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.
Commercial Wall Waterproofing in Portsmouth
Restaurants, gyms, salons and offices often have restrooms, locker rooms and kitchens with constant water exposure. We waterproof commercial showers, mop sink walls and restroom wet walls with durable membranes. Work can be scheduled after hours to reduce downtime. We also repair the plumbing behind those walls when leaks are discovered.
Commercial Walls Waterproofing in Portsmouth
Beyond residential properties, FBN Plumbing also offers walls waterproofing services for commercial buildings in Portsmouth. Protecting commercial basements, equipment rooms, and underground parking garages from water damage is vital to business operations. We understand the need for minimal disruption and efficient project completion for commercial clients. Our team works with property managers and business owners to implement robust waterproofing solutions that fit the demands of commercial structures and their code requirements.
Crawl Space Vapor Barriers in Portsmouth
Many homes in Portsmouth have crawl spaces, which are very prone to moisture issues. Installing a heavy-duty vapor barrier on crawl space walls and floors is a key waterproofing strategy. This thick polyethylene sheeting prevents ground moisture from evaporating into the crawl space, protecting subflooring and joists and improving indoor air quality. It's an effective way to control humidity and prevent wood rot.

Waterproofing Costs vs. Repeat Water Damage in Portsmouth, VA
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.

Frequently Asked Questions About Walls Waterproofing in Portsmouth
The cost of walls waterproofing in Portsmouth, VA can vary significantly 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 clear, itemized quotes after a thorough inspection.
We commonly install Schluter Kerdi, Custom RedGard, Laticrete Hydro Ban and similar systems. The right choice depends on your shower design and tile. We follow each manufacturer's installation steps to keep the warranty in force.
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 specifically engineered 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.
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.
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.
Look for bubbling paint, soft drywall, stained baseboards and musty odors. White crust on block or stucco walls is another sign of moisture moving through. Loose tiles or cracked grout in a shower also suggest water is getting behind.
Sprinklers and drip lines aimed at the house are the most common cause. Heavy storms and poor grading also send water toward walls. Masonry absorbs that water and leaves mineral deposits as it dries out.
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.
