Job Stories From Chantilly, VA
Sump Pump replacement in Chantilly, VA

When a homeowner in Chantilly, VA, noticed their sump pump couldn’t keep up with heavy rainfalls, letting water seep into their basement, they decided it was time for an upgrade. Concerned about the potential damage to their home—and eager for a solution—they reached out to us at NV Waterproofing and Foundation Repair. Upon contacting our customer care team, an appointment was swiftly arranged for a comprehensive home inspection. Our experienced System Design Specialist visited their home, providing a detailed look into the cause of their water issues and proposing a solution tailored to their specific needs. The verdict? Our TripleSafe Sump Pump system paired with IceGuard for additional protection against freezing and blockages, ensuring their basement would remain dry all year round. Our production team, proficient and prepared, arrived at the homeowner’s residence and went straight to work, showing great respect for the property and maintaining clean workspaces throughout the installation process. The installation of the TripleSafe Sump Pump system, recognized for its reliable three-pump design capable of tackling varying volumes of water, including in power outages thanks to its battery backup pump, was executed smoothly. Notably, the IceGuard system was set up, a vital component for homeowners in Chantilly, distinguished for its capability to expel water away from the foundation, even if the discharge lines are frozen or clogged. The outcome? A thoroughly dry basement, a grateful homeowner, and the peace of mind knowing their new system with a robust backup would withstand the heaviest of downpours.

Crawlspace remediation in Chantilly, VA

The customer experienced issues with unsteady, bouncing floors and moisture problems in their home's crawlspace in Chantilly, VA. Following an in-depth evaluation by our Technical Advisor, it was discovered that the existing support system in the crawlspace was inadequate for the floor above. To address this, we installed Smart Jacks to reinforce the floor joists, which not only supports the floors but can also realign floors and walls back to their original positions in certain cases. Additionally, we implemented a Clean Space Encapsulation system to prevent any water vapor from entering the space. We also constructed a new entrance to the crawlspace, ensuring easy access for any necessary future maintenance or inspections. With these improvements, the homeowner can now enjoy a crawlspace that is both dry and structurally sound.

Hello! We've recently experienced some water leaking in the basement due to heavy rain.

Foundation repair estimate
Project Location: Chantilly, VA
Our home was built in 2004, and we purchased it in 2017. Since moving into this home, we have noticed some signs that we may have some structural issues and would like a professional review and discussion on whether these issues should be of concern, or if they are a normally part of the home settling over time. We have noticed the following: 1: Small cracks in the garage concrete floor and bowed walls. 2: Sinking in the driveway, near where the garage meets the driveway 3: Cracks in exterior wall underneath the garage and underneath the deck 4: Sagging and separating of the siding near one of our rooms, that is over the side entry to the home 5: Bowed truss in the attic dormer space. 6: Sidewalk sinking and cracks in brickwork at Side Porch Steps and front walkway. We would like a professional evaluation and recommendations associated with these concerns at the earliest possible date.
