Basement Waterproofing in Ocean County, NJ

A. Pennacchi & Sons inspects your Ocean County basement and builds a waterproofing plan around the water problem it actually finds.

Basement Waterproofing in Ocean County, NJ

No Two Basements Need The Same Plan

One basement has poured concrete walls, another has block or old stone. One sits below a downspout, another below a slope. Each detail changes how water reaches the wall and where it collects, which is why a plan copied from the house next door often fails.

A. Pennacchi & Sons looks at those conditions before recommending anything. Four generations of the same family have done masonry and waterproofing in New Jersey since 1947, serving Ocean County from our Hamilton shop. Call (609) 394-7354 or request an estimate.

Where Basement Water Comes From

Water gets in through a cracked wall, a failing window well, a gap at the floor line or poor drainage outside, and often through more than one at once. That is why we inspect the basement and the outside before we recommend a fix. Frozen soil presses on the wall in winter, and each thaw drains into any crack, so a leak scoped this fall is smaller than one scoped next year.

Basement Waterproofing Services We Provide

Foundation wall dug out and sealed from the outside

Interior Waterproofing

We cut along the basement perimeter, bed a perforated pipe in washed stone as a French drain, and route the water to a sump pump.

Exterior Waterproofing

We excavate the foundation wall, apply a membrane, and add drainage board and pipe, so water meets a barrier before it meets the wall.

Sump Pumps And Battery Backup

A sump pump without power cannot move water, and heavy rain often comes with outages. A battery backup gives the pump a second power source.

Foundation Crack Repair

We inject foundation cracks, patch cracks in the floor, and seal each spot where water gets in. Larger foundation problems need a site visit first.

Window Well Drainage

When a window well collects water, it soaks the wall behind it. We seal the well and fix the drainage around it.

Below and above grade waterproofing for commercial and multi-unit buildings: foundations below grade, plus parapets, terraces and parking decks above it.

What Drives The Cost Of Basement Waterproofing In Ocean County

The cost depends on how much water is in the basement, where it enters and what the foundation is made of. Interior systems cost less than exterior excavation, and some homes need both. Cracks, a leaking window well and a battery backup each change the scope.

A. Pennacchi & Sons sets a price after inspecting the basement, then sends a written proposal with one total that shows the work we recommend and why.

Frequently Asked Questions

Do I need a sump pump with a battery backup?
If the basement depends on a sump pump, a backup is worth considering. Heavy rain often comes with power outages, and a pump without power cannot move water. A. Pennacchi & Sons can include one in the proposal.
Should my basement get interior or exterior waterproofing?
Exterior waterproofing keeps water from reaching the foundation wall and needs room to dig. Interior systems catch water that has already entered. Your basement conditions decide which fits.
Will a dehumidifier fix a damp basement by itself?
A dehumidifier lowers humidity, but it cannot stop water entering through cracks or the walls. If the basement stays damp, call (609) 394-7354 and we will find the source.

“I had a roofer come out for a small leak in my attic. He fixed it and while up on the roof took pictures of my chimney. Told me I had a big problem. Lot of mortar missing. I called A. Pennacchi & Sons. Paul came out the next day. He told me what needed to be done and gave me a price. I asked him if I should add a few bricks to the top. He said "why do you want to spend more money?" What contractor says that? The men came out a few days later. On time, polite, got right to work, and cleaned up like they were never there. Paul had given me a choice of colors. His price was the best one. My chimney now looks absolutely beautiful. I would give them 10 stars.”

“Great experience with Paul and the Pennacchi team. We contracted this firm to waterproof our basement and replace our basement windows. Nick was excellent at coordinating the effort, including preparation, window replacement, waterproofing, clean up, and follow up to inquire about and resolve a few questions. Happy to recommend Pennacchi and Sons.”

“Pennacchi sealed our basement 2 years ago. After a recent heavy rain we noticed seepage and asked Pennacchi to look at it. They sent Nick, who did an excellent job diagnosing the problem, finding the most likely seepage site, and then repairing it. Nick came by the next day, inspected the repair, and also improved sealing of 2 utility pipe entries. The rapid response, competency, diligence, and follow-up were excellent.”

“We are so impressed with Pennacchi & Sons. Multiple people recommended this company as the best in the region. For a company with a huge legacy, working throughout the county, there was no hesitation to see what our small job looked like and whether they could help. The crew was friendly, timely, and efficient. Ray walked us through the process, gave us a play-by-play for the best understanding of the work, and answered tons of questions. The end result was better than the original.”

“Pennacchi has an exceptional reputation and we now have firsthand experience of their stellar work. The precision craftsmanship and professionalism are impressive. We had our chimneys repointed, brickwork restored, and a basement wall resealed. It all blends seamlessly and looks gorgeous. Ask for Sam as your foreman if you can, he was amazing. The entire crew was fantastic. Kudos to Paul and the leadership for building a great team. Impeccable service and beautiful finished product.”

“Water was getting into my house because of the old brick exterior. It needed to be repointed and painted on the interior. Although this was a very small job, Paul and his son Paul Junior were incredibly professional, listened, and addressed my concerns. I left their crew to complete the work without being home and everything was safe and secure when I got back. They kept their work areas clean and took away their trash. Paul’s price was the most competitive. HIGHLY RECOMMEND.”

“My basement was leaking really bad and had 2 different companies come out and try to fix the problem with no luck. Decided to try a third time and luckily I came across APS. They came out and did amazing work and solved all my issues. Put in a French drain, sump pump, and stuccoed the walls. They had to fix all the problems the other companies did, and it was a great experience working with them. Paul was extremely professional. Highly recommend if you need the job done right the first time.”

“We hired Pennacchi and Sons to waterproof our basement. We did not necessarily have issues, we just wanted to prevent any moisture problems in the future. We consulted with a few other people before speaking with Paul, the owner. Paul came up with an effective and cost-effective solution for us. We are very happy with the service and highly recommend Paul to everyone.”

“These guys did an amazing job for us. 20 years of trying to get my basement dry and these guys finally got it to work. We actually had another company do it 15 years ago but we always got water back. Paul and his brothers worked hard and they cleaned us up as well. Thanks for letting me tell this story guys.”

“I hired Pennacchi and Sons to do repair work on my chimney. In the 3 days they were here, they did an excellent job from start to finish. They also left my home in the same condition as it was before they came. I could not recommend this company more and would definitely hire them again if I needed future masonry work done.”
