The drainage system also works as part of crawl space encapsulation.

Foundation Repair & Concrete Leveling

Whatever the issue we are the trusted foundation repair contractor. Our foundation repair experts will visit your home, identify the issue and recommend the right solution. We provide permanent foundation repairs using non-invasive methods. There is no need to tear up your entire yard to fix the foundation.

Job Stories From Dover, NJ
Lifted Sidewalk in Dover, NJ

A homeowner in Dover, New Jersey had a part of their sidewalk that was sinking and settling and contacted Quality 1st. Our Specialist went to inspect the sidewalk and had our team install PolyLevel, a polyurethane foam to raise the concrete back to its original position. The PolyLevel is injected into the concrete through penny-size holes and the foam starts to expand and lift the concrete within minutes. This process is quick and a permanent solution.   

  Do you have uneven, sinking concrete? There is a solution! Contact Quality 1st for your FREE estimate today!

Foundation Fixed in Dover, NJ

A home in Dover, New Jersey had bowing walls in the basement. Bowing walls, or walls being pushed inward are usually caused by expansive soils or hydrostatic pressure. Our System design Specialist inspected the home and noticed there were also stair step cracks on the foundation walls. To solve this problem, GeoLock Wall Anchors were installed by extending from the wall to the stable, hard packed soil beyond the home. This system is anchored into the stronger soils and braces the foundation wall, preventing further movement. This home is now stabilized and will not have any more foundation problems.       

An unstable foundation is no joke, contact the experts at Quality 1st for your FREE estimate!

WaterGuard Installed in Dover, NJ Home

A basement in Dover, New Jersey was experiencing water coming in through the walls every time it rained. Quality 1st was called to inspect the basement. WaterGuard was installed along the edge of the basement, underneath the floor slab to prevent clogging. This way the system is out of the mud zone and will not clog. The TripleSafe sump pump was installed to pump water out of the basement and keep water out.

The Triplesafe sump pump has three different levels of pumps so the basement is always protected in case of a pump failure. Finally, CleanSpace vapor barrier system was installed on the walls to hold back water vapor and humidity, directing the water to the sump pump. With this new system installed this basement is waterproofed and will not experience any more water.

Homeowner's Porch Foundation Concerns Alleviated in Dover, NJ

Hilda D. of Dover, NJ became concerned when she noticed that the floor in her enclosed front porch was starting to lean.  When she looked around outside, she noticed that the porch was starting to separate from the main home.  There was also some stair-step cracking in the cinder block foundation of the porch.  She sought help from Quality 1st Basement Systems.

Certified foundation repair specialist Ken Peare traveled to Dover to meet Hilda.  Ken completed a thorough exterior inspection of the porch as well as an interior inspection in the crawl space beneath the porch.  Ken’s expertise resulted in the determination that the brick columns and concrete block foundation were no longer providing sufficient support for the porch.  Ken explained that what Hilda noticed were common signs of structural failure due to a combination of moisture and settlement over time; however, he was able to provide the solution that would eliminate Hilda’s concerns.

Project Manager Juan Garcia and his crew mobilized to Dover to repair Hilda’s porch foundation and crawlspace.  They installed a series of SmartJack steel supports to lift the floor and provide continued support.  Additionally, the patented PowerBrace system was installed to support the walls and potentially straighten them over time.  Lastly, Hilda liked what Ken proposed about isolating the crawl space from the earth and keeping the area cleaner and drier, so the crew encapsulated the crawl space with TerraBlock insulation and a CleanSpace liner as well as adding SilverGlo insulation panels.  Hilda D. was thereafter able to enjoy her newly-stabilized front porch with added energy savings from the crawl space repairs!
