 Trustindex verifies that the original source of the review is Google. We feel very fortunate to have found this company. I met with Mike regarding leaks in the basement. He assessed the entire house, gave me options and clearly explained the process. Everyone from Mike, to the secretary in the office to the workers were absolutely amazing. They did the work as promised, gave us a reasonable price, and left the place immaculate. We could not be happier with the results! This is a great family owned business. You can’t go wrong!

 Trustindex verifies that the original source of the review is Google. Mark took it upon himself to come to my home and examine my issue himself.  He is knowledgeable not only in basement waterproofing, but also in land grading, excavating and several other adjacent topics.  While it was concluded my issue was not foundation oriented, he did not hesitate to propose several other creative ideas to help address my issue.  He has a great disposition, and I would not hesitate to recommend his services to others.

 Trustindex verifies that the original source of the review is Google. I bought my house 24 years ago, and for 24 years I lived with water coming in to my finished basement.
A few years back I hired another company to put in a French Drain System which never worked.
As the storms got worse the water in my basement increased.  Because of my previous experience I was hesitant to hire another company until I read about ACM and met Mark who was highly recommended by my Home Service Company.
Mark spent about 2 hours explaining the process, and what was needed.
In February 2025 ACM put a extensive French Drain System  which included taking down the sheet rock walls, demoing tile and placing a membrane along the whole perimeter of the drain system. All of this work was completed in 3 days exactly what Mark said.
The guys were professional, polite, and best of all they were careful to save my Radiant Heating System which was under the tile.
Since the French Drain System was placed I have not had 1 drop of water coming into my basement.  I am very grateful to Mark's ACM Company, and was able to refinish my basement without fear of water damage.
I highly recommend ACM Basement Water Proofing to all who are having water problems with their basement.

 Trustindex verifies that the original source of the review is Google. I chose ACM because of their "Best of Long Island" award, and I'm glad I did. Mark's crew (led by Joe) installed an interior French drain  and a sump pump in our basement. Six months later, we've had no problems with water. These guys know what they're doing.

My wife and I would like to say thank you to Mark and his team for their excellent work installing a French Drain in our finished basement. For years we had to worry about flooding if we got a large amount of rain in a short time. The entire staff was totally professional. knowledgeable, competent and efficient. They were clean and caring and after each day they protected the whole worksite. Without a doubt, we would recommend them for all your basement waterproofing needs.

 Trustindex verifies that the original source of the review is Google. I called acm after finding water in the basement. Mark answered the call and quickly helped diagnose the issue. He guided me to check baseboard and sure enough a broken valve was causing this leak. It's good to find someone to help a homeowner without rushing to take their money. It's good to find a honest business man

Basement Battery Backup Sump Pumps in Long Island Near You

Suffolk County & Nassau County’s Trusted Company for Backup Sump Pump Installation

A sump pump is a key part of a Long Island interior basement waterproofing solution, but even the best sump pump won’t work without power. If there is a power outage in your area during a rainstorm, your basement may be left unprotected from outside water.

With a battery backup sump pump, your Long Island waterproofing system stays online, protecting your home even when the power doesn’t. The battery-backup collects any water from the french drain and pumps it up, out, and away from your home. That’s why ACM installs battery backup pumps as part of every waterproofing system we recommend.

Do I Need a Battery Backup Sump Pump in my Long Island Basement?

If you live on Long Island, a battery backup sump pump isn’t just a luxury—it’s a smart layer of protection for your home. During major storms or Nor’easters, power outages and flooding often happen at the same time. Without power, your primary sump pump won’t run—and that means your basement could start taking on water within minutes.

You especially need a battery backup sump pump if:

You’ve experienced basement flooding during power outages
You live in a flood-prone or low-lying area of Nassau or Suffolk County
Your home has only one sump pump with no backup
You want peace of mind while traveling or during storms

If you’re searching for battery backup sump pump installation near me or wondering if your home is at risk, ACM Basement Waterproofing offers free inspections and honest recommendations. We’ve helped countless Long Island homeowners nearby avoid costly water damage with reliable backup systems.

How a Battery Backup Sump Pump Works

A battery backup sump pump system is designed to kick in automatically when your main sump pump fails or the power goes out. Here’s how it works:

Constant Monitoring: The backup system stays on standby while your main sump pump handles everyday drainage.
Automatic Activation: If the water level rises and the main pump isn’t functioning—due to electrical failure—the backup pump’s float switch rises and turns it on.
Battery Power: The pump is powered by a rechargeable battery, so it doesn’t rely on electricity from your home.
Discharge and Drainage: Water is pumped out of your basement and away from the foundation using the same or a dedicated discharge line.
Recharging: After the outage ends, the system recharges automatically, ready for the next emergency.

This is especially useful for Long Island basements that may see storm surges, heavy rainfall, or saturated ground conditions.

How To Install a Battery Backup Sump Pump

Installing a battery backup sump pump should be done by a professional. Here’s what the ACM installation process typically involves:

Inspection & Planning
We assess your basement, primary sump pump setup, and flood risk. Every Long Island home is different, and we customize the system to match.
Selecting the Right Backup Pump
We choose a unit that complements your main pump—based on size, water volume, and how long the system may need to run during an outage.
Installing the Battery Backup System
The new pump is placed in the same or adjacent sump pit. We connect it to a powerful, maintenance-friendly battery that remains on charge at all times.
Testing & Calibration
We test the float activation, discharge performance, and switch between power modes to ensure everything runs flawlessly.
Optional Features
We can install alarms, Wi-Fi monitoring, or smart sensors that alert you when the battery kicks on or needs maintenance.

Looking for backup sump pump experts near you? ACM is here to make sure your basement stays dry—no matter the weather.

We Keep Your Basement Permanently Dry

At ACM, we always recommend to our Long Island customers that they consider a backup system. The simplest type of backup consists of a second pump. The float on this backup pump is positioned a few inches higher than the primary pump.

This way, if the primary pump should fail for any reason or if the water in the sump is rising too fast for the primary pump, the backup pump will automatically come on, ensuring that your basement remains dry.

Proven Battery Backup Pumps

Because the pump runs on your Long Island home’s electricity, it will not function during a power outage. This can be especially problematic due to the fact that power outages often coincide with the heaviest rains. Because of this, it is sometimes wise to consider a battery backup sump pump system.

A wet basement is an unhealthy basement, and you don’t want to face the health risks of basement water. So, be sure to ask about adding a battery backup pump to your Long Island home when speaking with your ACM representative. We are Long Island’s battery backup sump pump experts.
