Job Stories From Herndon, VA
Foundation Cracks in Herndon, VA

Recently, a homeowner in the charming town of Herndon, VA, encountered an unsettling discovery shortly after settling into their new residence. During a routine inspection, they uncovered large, ominous vertical cracks sprawling across the foundation walls of their home. Heeding the advice of their diligent inspector, the homeowners sought the expertise of a professional to assess and address this alarming issue. This led them to the renowned services of NV Waterproofing and Foundation Repair.

Upon contacting us, we dispatched our esteemed technical advisor, Brian Bui, to undertake a comprehensive evaluation of the property. Brian, known for his meticulous attention to detail and vast experience in foundation repair, conducted a thorough inspection. His findings confirmed the homeowners' fears: the cracks were not only significant but posed a serious threat to the structural integrity of the home if left unattended. The situation demanded immediate action to prevent any potential exacerbation that could lead to major damage in the future. Understanding the gravity of the situation, our team proposed a robust solution tailored to fortify the home's foundation effectively.

The cornerstone of our approach involved the installation of five push piers. These devices are specifically designed for use in stabilizing heavier structures. They operate by utilizing the weight of the home itself to exert pressure downwards, gently pushing the foundation back into its original, correct position. This innovative technique offers a formidable solution to counteract the unsettling effects of foundation settlement. In addition to addressing the underlying issue of foundation displacement, our specialists turned their attention to the visible cracks marring the foundation walls. With precision and care, they embarked on a meticulous process of cleaning each crack, preparing them for the application of a high-grade polyurethane solution. This specialized sealant was carefully injected into the cracks, filling them completely to form a resilient barrier against water infiltration and further structural compromise. The homeowner watched as our team transformed their initial concern into a comprehensive restoration of their home's foundation integrity. Their satisfaction with the process and the final results was palpable. They expressed immense relief and gratitude, comforted by the knowledge that their home was now supported by a solid, secure foundation. The peace of mind that comes from knowing your home is safe and sound is invaluable, and we were proud to provide that reassurance. This project stands as a testament to the importance of prompt, professional intervention when facing foundation issues. At NV Waterproofing and Foundation Repair, we're committed to delivering solutions that not only address the immediate concerns but also ensure long-term stability and security for your home. The homeowner in Herndon, VA, can now enjoy their dwelling to the fullest, confident in the enduring strength of their foundation.

I want to discuss some foundation crack issues from home inspection with you.

During the recent heavy rains that we currently experienced my sump pump in the basement was not plugged in. I coming down the steps I noticed water glistening at the bottom of the basement wall. I came back to look at the sump pump and plugged it back in. The pump ran for about 15 - 20 minutes. Across a couple of days this white stuff started appearing on my basement floor. I have since learned this stuff is called Efflorescence. I want someone to come and look at my basement to make sure all is well. Thanks

Hello. I am reaching out to schedule an appointment for foundation inspection. We found some water in the basement after several times of heavy rain in spring this year. After that, the floor became a little uneven and there were some dead bugs found in the basement every week. We're looking for some experts diagnosing any problem with the foundation.
