In Upper Marlboro, MD, one homeowner found themselves facing a familiar but frustrating issue—a sinking front entryway sidewalk. What once offered a welcoming path had become uneven and unsafe, casting doubt on both the home’s appearance and its structural integrity.

That’s where NV Waterproofing and Foundation Repair stepped in with innovative, lasting solutions. Our team used PolyLevel®, a high-density polyurethane foam, to gently lift and level the sunken concrete—restoring the walkway without the need for messy demolition or costly replacement. To protect that repair for the long haul, we applied NexusPro®, a UV-resistant joint sealant designed to keep water out and prevent soil erosion.

Now, the front entryway isn’t just level—it’s resilient, attractive, and built to withstand Maryland’s changing weather.

 

At NV Waterproofing and Foundation Repair, we don’t just fix concrete—we deliver confidence, curb appeal, and safe footing for years to come. If your sidewalk is sinking or cracked, let us help you reclaim the path forward with precision and care.

Job Stories From Upper Marlboro, MD
Upper Marlboro, MD Crawl Space Repair Restores Stability and Comfort Beneath the Floors

In Upper Marlboro, MD, a homeowner was facing a frustrating and familiar problem: their floors felt cold, uneven, and soft underfoot. While it may have seemed like a minor comfort issue at first, the true culprit was far more serious—moisture damage and weakening structural supports in the crawl space below. Recognizing the signs, they reached out to NV Waterproofing and Foundation Repair, Maryland’s go-to experts in crawl space and foundation solutions.

Our team responded quickly. After scheduling an inspection with our responsive Customer Care Specialist, a skilled System Design Specialist conducted a thorough evaluation of the crawl space. What we discovered was excessive moisture and sagging floor joists—symptoms of long-term water intrusion and poor air circulation beneath the home.

To address the problem at its root, we installed a full crawl space support and waterproofing system. The first step was stabilizing the structure using our SmartJack® Support System—an adjustable, galvanized steel solution that lifts and secures sagging joists, restoring strength and levelness to the floors above.

Next, we encapsulated the crawl space using CleanSpace®—a heavy-duty vapor barrier engineered to seal out moisture and humidity. This was paired with CleanSpace® Drainage Matting, which channels any incoming water to a newly installed SuperSump®—our high-performance sump pump system designed to keep the area dry year-round.

The result? A transformed crawl space that’s dry, energy-efficient, and structurally sound. The homeowner now enjoys warm, even floors and peace of mind knowing their home is protected from future moisture damage.

If you're experiencing similar issues in Upper Marlboro or nearby areas, NV Waterproofing and Foundation Repair is here to help. From cold floors to foundation shifts, we deliver customized, lasting solutions that protect your home—starting from the ground up.

Cracker in the basement
Project Location: Upper Marlboro, MD
After the recent storms, I noticed the rain heavily pouring through the top of my basement window seal into my home. From the inside, I cannot visualize any damage. But my concern is water damage behind the walls. Less than a year ago, I just had vinyl floors installed in my basement. I also have a deck that is above the window seal. I do not know how or where the water is getting in from the outside. I would like to get an inspection and an estimate please.
