A New Jersey couple was purchasing this Ewing house when their realtor noticed that there was a bowing wall in the cinderblock foundation. Quality 1st Basement Systems inspected the basement and noted two horizontal cracks that run about 10 to 14 feet across the basement. The installation team installed Wall Anchors to stabilize the wall and will straighten the wall over time so that it can return to its original position.

Job Stories From Trenton, NJ
Repaired Sunken Patio Area in Trenton, NJ

Trenton homeowners were experiencing lifting and settling slabs on their backyard patio. The unevenness was causing their patio furniture to move and tilt when they used it. They knew that the patio needed to be repaired but they wanted to find a solution that would prevent them from having to replace it. Luckily, a neighbor of theirs knew someone who was a Concrete Repair Specialist for Quality 1st Basement Systems and decided to call for a free estimate. Concrete Repair Specialist, Tom Carrano, met with the homeowners and upon inspection measured 3 inches of settlement in some areas of the the patio and up to 5 inches in others. 

Tom, explained that PolyLevel is a foam solution that is injected underneath the concrete slab. Once underneath, the foam begins to expand and harden, raising the slab back to its original level. Each slab was raised, completely elevating the entire patio area. 15 minutes after the crew was finished they helped the homeowners put their patio furniture back outside. They appreciated the crews help with the furniture and were pleased that they could use their patio right away! 

From Basement To Beautiful in Trenton, NJ

Homeowners living in the beautiful area of Trenton, NJ contacted Quality 1st Basement Systems after seeing an advertisement for basement finishing. They had spoken about finishing their basement before but it was never a top priority until they found out they were expecting. With a third child now in the mix, the playroom upstairs would have to be turned into a nursery, leaving the kids without an area to play in. Quality 1st Basement Systems sent Total Basement Finishing Expert, Thomas Nehme out to help design a brand new play room area for the children in the basement. 

After Thomas did a full inspection of the basement area, he began working together with the homeowners to design the perfect area for their children. The homeowners picked the ThermalDry Flooring because they liked having the option to replace one individual section of the carpet if it stains. The fact that the flooring has pegs underneath it allowing air flow to keep the floor up to 10 degrees warmer was a plus for mom! Next, EverLast Wall Restoration was installed which are basement wall panels with built-in insulation. 

The homeowners were amazed at their basement transformation! Quality 1st was able to turn their dark unfinished basement into a beautiful, bright play room area for their children to enjoy. 

SuperSump Sump Pump Installation

Homeowner Lisa M. was getting water in her basement during heavy rains.  She searched for a permanent waterproofing solution and contacted Quality 1st Basement Systems for their expert advice.  Bruce Kaminsky, waterproofing specialist, met Lisa M. at her Trenton, NJ home and recommended the SuperSump sump pump, UltraSump battery backup, the WaterGuard interior basement waterproofing system, IceGuard, and LawnScape. 

The SuperSump sump pump system is the finest sump pump on the market.  It pumps 2220 gallons per hour at an 8-foor discharge head quietly and efficiently.  This pump also has an airtight lid that keeps sump pump odors in and any bugs or pests out.  If for any reason the pump failed to turn on, the UltraSump batter backup sump pump system would pick up to ensure a dry basement.  Whether there is a power outage or a circuit breaker is tripped, your basement will still stay dry.

Thanks to Wilver Cardoza and his qualified waterproofing crew, these products were installed in one short day!  Lisa M. can now enjoy a clean, dry, and healthy basement for years to come.  

Complete Waterproofing with CleanSpace Walling

When basement water was causing problems for Andrew D. and Cathy P. in their Trenton, NJ home, they knew if was time to call Quality 1st Basement Systems for some help.  Waterproofing professional Kenny Tramutola went out and talked to Cathy.  She told him that they were getting a bad smell from one of the walls and that it was getting increasingly worse.  Kenny suggested CleanSpace walling, a SaniDry dehumidifier, and the WaterGuard interior basement waterproofing system.

CleanSpace walling is made of a heavy, durable plastic liner.  It not only works as an effective vapor barrier, but also creates a dramatically brighter basement space.  Your dark basement will have a whole new light after this basement wall system is installed.  The SaniDry dehumidifier is energy efficient and keeps relative humidity at a low percentage in your basement.  This will prevent mold and mildew from growing, eliminate musty odors, and protect your family’s health. 

About a year after Andrew D. and Cathy P.’s basement was waterproofed, they contacted Quality 1st Basement Systems when more water was coming into their basement during heavy rains.  A SuperSump sump pump was then installed to ensure a dry basement all the time.  Now they no longer have to worry about basement moisture or water no matter what the conditions are. 

Leaky Basement Doors? We have the Solution for You!

Bilco basement doors are sometimes the source of basement water.  For Michael D.’s Trenton, NJ basement, this seemed to be the problem.  He contacted Quality 1st Basement Systems for a free estimate and a permanent solution for his leaky basement doors.  Waterproofing expert Kenny Tramutola went out to his home and came up with a comprehensive waterproofing solution. 

Juan Garcia and his team went out to install the SuperSump sump pump with the UltraSump battery backup system that will keep the basement from flooding no matter what the conditions are.  This battery backup sump pump will turn on if there is a power outage, if the circuit breaker is being tripped, or even if the primary motor fails.  No matter what happens, be assured that your basement is always dry!  To address the leaky bilco basement doors, a TrenchDrain system was installed.  This is a drainage channel installed at the base of the exterior stairway to capture any water leaking in and direct it to the sump pump and out of the basement. 

Michael D. no longer has to worry about a wet basement.  With the help of Quality 1st Basement Systems, his basement will by dry for years to come!

My family of five live in a townhouse. The 1st floor is the only common space. We need to finish our basement --as a multi-use space. Right now - everyone retreats to bedrooms as compensation for the lack of space. The priorities for the basement are: 1. A comfortable seating area for media and socializing. 2. Office/workspace to meet the needs of 3 HS students and small private-office for my husband and myself. 3. Small Exercise area that is semi- private. ( if budget permits. 4. Storage area - we just need an inexpensive track door. 5. The basement has minimal electrical outlets and no real lighting- electrical will be one of the more significant things. We want our basement to have a clean & finished appearance. However, we have a moderate budget and cannot afford to be elaborate. Please let me know when/if you would like to visit for a look at and discuss the basement project. Phone contact preferred. Thanks so much.... Shari Goldberg
