"This was a big job The project took around 10 days. At first we were going to just do the front steps but were talked into doing the pathway as well. We are glad we did. We also had him re-point and repair the brick masonry along the base of the house. The final look is beautiful. Very professional job. Masonry work is top-notch."

"We used quality 1st on two occasions in the past year to address water in the basement of our brownstone. They first addressed the problem from the crawlspace - installed a sump pump, water guard trench, and cleanspace wall system (they also added support to the ceiling, which is the floor of a kitchen above). Their approach was sound, the cost was fair, and we were very happy with their service and the work itself. They then returned to address water coming in from the main basement area - we worked together on a reasonable approach that included adding a 2nd sump pump, a water guard trench and cleanspace wall system only where needed. This required a lot of coordination and communication with our plumber as well - all went smoothly, work was performed and cleaned up professionally. So far, so good! I am in construction myself and I reviewed their approach with other professionals including an engineer, and I have a lot of confidence in their products, their pricing, and their work."

"They explained their system and the installation process in detail. They were very flexible and worked with our schedule to finish installation of French drain system before sale of house. Extra foundation work was needed, and they did that as fast as possible"

"I can't say enough good things about American A-1 Waterproofing. Roland and his team were amazing. I had originally opted to go with another contractor to install a French drain and sump pump, but after exposing the foundation, they got spooked and said they wouldn't perform the work. Roland came by and assured me his team could get the work done and they did not disappoint. Through the initial estimate, permitting, construction and final sign off, Roland and his team were communicative, prompt, clean, and extremely professional. It was an absolute pleasure to work with them!"

FAQs for concrete foundation repair projects in Cedar Knolls, NJ

Visible cracks, water leaks, uneven floors, or walls that won’t line up are classic red flags. You might also notice sticking windows, doors that no longer latch, or exterior cracks crawling up brick or siding. Even a damp, musty basement can hint at trouble. If you spot any of these, call a foundation pro right away. Early inspections cost far less than waiting until the damage threatens your home’s stability.

Yes, foundation problems impact your home’s value. Buyers want proof that the foundation is stable, and a recent, professional repair can actually boost confidence in your home. You’ll need to disclose the work, but documentation showing the structure was properly stabilized, especially with piers in regions known for shifting soil, often reads as a plus, not a problem. Skipping repairs, on the other hand, can cut your sale price and shrink the pool of interested buyers. Taking care of the issue protects both value and peace of mind.

Foundations are engineered for exceptional longevity when constructed correctly and maintained diligently. Concrete slab foundations remain structurally sound for 200 years, while other foundation types deliver integrity between 75 and 100 years. Regular professional inspections and timely maintenance further secure a foundation’s lifespan and ensure your home stays safe over the long term.
