Your Basement Stays Dry Year-Round

You’ll sleep better knowing your basement is protected 24/7. No more rushing downstairs during storms to check for water. No more moving everything off the floor when heavy rain is forecasted.

A properly installed basement sump pump system handles the water before you ever see it. The pump activates automatically when water levels rise, directing it safely away from your foundation.

Sump Pump Installation Process

Here's How We Protect Your Basement

First, we assess your basement’s specific water issues and determine the best location for your sump pump system. We look at your foundation, existing drainage, and how water typically enters your space.

Next, we excavate the sump pit at the lowest point of your basement floor. The pit gets lined with gravel for proper drainage, and we install the sump pump with appropriate discharge piping that directs water well away from your foundation.

We test the entire system to make sure it activates properly and handles the water volume your basement might see. You’ll know exactly how your new system works and what to expect. The installation includes cleanup, and we make sure you understand basic maintenance to keep everything running smoothly.

What's Included in Your Installation

Your sump pump installation includes the pump, basin, discharge piping, and proper electrical connections. We use high-quality pumps designed for Long Island’s conditions, not the cheapest options that fail when you need them most.

Every installation comes with battery backup options to keep your system running during power outages. Storms that cause flooding often knock out electricity, so your protection shouldn’t depend on the power staying on.

We handle the permits and make sure your installation meets local codes. The discharge line gets routed properly to prevent water from returning to your foundation, and we include a check valve to prevent backflow into your basement.

Most sump pump installations take 4-6 hours, depending on your basement’s concrete thickness and existing conditions. If we need to break through especially thick concrete or work around existing utilities, it might take a bit longer. We’ll give you a realistic timeline upfront so you can plan accordingly. The process involves excavating the sump pit, installing the pump and discharge piping, making electrical connections, and testing everything thoroughly. We clean up completely when we’re done, so you’re not left with a mess.
The right size depends on your basement’s square footage, how much water you typically see, and your soil’s drainage characteristics. Most Selden homes need a 1/3 to 1/2 horsepower pump, but homes with larger basements or severe water issues might need 3/4 horsepower or higher. We measure your space and assess your water volume during heavy rains to recommend the right capacity. A pump that’s too small won’t keep up during heavy storms, while an oversized pump cycles on and off too frequently, wearing out faster.
Yes, especially on Long Island where storms that cause flooding often knock out power. Your sump pump won’t work without electricity, which means you’re vulnerable exactly when you need protection most. A battery backup system keeps your pump running for several hours during outages, giving you peace of mind during severe weather. The backup battery charges automatically when power is on and takes over seamlessly when it’s not. It’s a small additional investment that prevents potentially thousands in water damage.
A quality sump pump typically lasts 7-10 years with proper maintenance. You should test it a few times per year by pouring water into the pit to make sure it activates properly. Check that the discharge pipe isn’t clogged or frozen, and make sure the pump sits upright in the basin. The battery backup needs replacement every 3-5 years depending on usage. We recommend annual professional maintenance to clean the pump, test all components, and catch small issues before they become big problems during the next heavy storm.
Yes, but it requires more careful planning to minimize damage to your finished space. We work around existing flooring, walls, and utilities to access the best location for your sump pit. Sometimes we can route discharge piping through existing utility chases or along basement perimeters to avoid major reconstruction. The key is finding the lowest point where water naturally collects, even if it means some repair work to your finished surfaces. We discuss all options upfront so you understand what’s involved and can make the best decision for your situation.
If your pump fails during heavy rain, water will start accumulating in your basement within hours depending on the severity of the water intrusion. This is why we recommend quality pumps with battery backup and annual maintenance. If you notice your pump isn’t working during a storm, turn off electricity to the basement if there’s standing water, and call for emergency service. A backup pump or temporary pumping solution can minimize damage until permanent repairs are made. Regular testing and maintenance catch most potential failures before they happen during critical moments.
