Mold Prevention and Crawl Space Waterproofing in Harrison, NJ Mold Prevention and Crawl Space Waterproofing in Harrison, NJ

This Harrison, NJ resident was purchasing a new home, however the home's crawl space had a strong odor, was damp, and had mold growth. Concerned about the safety of the house, he called Quality 1st Basement Systems to remedy the problem.

The fiberglass insulation was wet and falling off the ceiling, creating a haven for mold and pests. CleanSpace vapor barrier was installed to keep water vapor out, pests away from the crawl space, and the humidity down. CleanSpace will not only prevent future mold growth, but it will save the homeowner on his heating bill and prevent energy loss. It is made out of durable, inorganic material that will not tear or rot. A new SaniDry dehumidifier will filter out dust mite droppings and mold spores, keeping the air healthy and the humidity down. Now this home is ready to be moved into and will stay dry, safe from mold, and odor free.

Crawl space repair & encapsulation experts

The crawl space is an often ignored part of the home. However, a humid, leaky crawl space can lead to massive problems if left unrepaired and dirty. If you're unsure whether your home has crawl space issues, the warning signs include musty smells, sagging floors, and condensation. The best way to get in front of a crawl space problem is to install a professional-grade sump pump. A crawl space sump pump will eliminate flooding and pooling water, preventing mold and mildew growth.

Another way to help ensure a safer, dryer crawl space is to install a vapor barrier. This energy-efficient solution keeps moisture and bugs out and helps your crawl space become a healthy, dry area. Additionally, a dehumidifier will work with the sump pump and thermal insulation to maintain a humidity-free environment in the crawl space.Our crawl space encapsulation system keeps the area from leaking heat or cold from the house.

Job Stories From Harrison, NJ
Concrete Driveway Repair in Harrison, NJ

A driveway should provide safety and stability, not tripping hazards and uneven concrete! This homeowner in Harrison, New Jersey saw their concrete driveway was sinking and becoming unlevel. This can happen when concrete is poured over poorly backfilled soil. Over time, this soil settles and creates voids underneath the slab. Another reason could be the soil constantly becoming saturated and dry from the weather. This can expand and shrink the soil, which can cause voids to form underneath. If this goes without repair, the uneven concrete could cause tripping hazards! 

The homeowner did not want this issue to go without resolution, so they searched online. They came across Quality 1st Basement Systems and gave us a call. Our customer care representative booked them an appointment with our System Design Specialist, Joseph DelVecchio. Joseph provided a thorough free inspection and estimate and suggested they use polyurethane foam to lift and level the concrete. 

A few days later, our foreman Ramon arrived at the home and began the process of using our PolyLevel Injections. This method is done by drilling small, penny-sized holes into the concrete and injecting the polyurethane foam into the voids underneath the slab. This process is repeated until the concrete slabs are raised. 

Within 20 minutes, the job was complete. When the homeowner saw the results, they were satisfied with the work and professionalism they witnessed on the job! They no longer had to worry about tripping hazards on their driveway!

Uneven Concrete Walkway in Harrison, NJ

When you begin to notice your concrete is settling, the best action to take is to call a professional instead of ignoring it. Ignoring the signs will only cause more settlement and eventually more damage. A homeowner in Harrison, NJ waited years before addressing their concrete issues resulting in an entire walkway area 10 slabs long with up to 4 inches of settlement. Luckily they contacted Quality 1st Basements for a free estimate on concrete lifting and leveling. Concrete Repair Specialist, Andy went out to inspect the walkway area and provide a solution.

Our PolyLevel team drilled small penny-size holes into the concrete slabs and began to inject PolyLevel Foam underneath to fill the void causing the settlement. Once the job was completed the entire walkway area was raised back towards its desired position. The customer was amazed not only at the installation process but how the entire area was left cleaner than when they started.
