Sump Pump Installation Company
Diamond Masonry & Waterproofing LLC has been solving basement water problems across Nassau County for years. We understand how Long Island’s soil conditions, water table, and storm patterns affect your basement.
Every sump pump installation we do accounts for your specific situation. The depth of your basement, the way water moves around your foundation, how your home was built – it all matters when designing a system that actually protects you.
We’re not the guys who show up, drop in a basic pump, and hope for the best. We’re the team that sizes everything correctly, installs backup systems, and makes sure you’re covered when the power goes out during storms.

Basement Sump Pump Installation
First, we assess your basement’s specific water challenges. We look at where water enters, how much volume you typically see, and what your current setup is or isn’t doing. This tells us exactly what type of basement sump pump system you need.
Next, we excavate the sump pit to the right depth and size for your situation. We install the basin, connect proper drainage, and set up your primary pump with the horsepower to handle your home’s water volume. Then we add battery backup so you’re protected during power outages.
Finally, we test everything thoroughly and show you how the system works. You’ll know what normal operation sounds like, how to check the backup battery, and when to call us if anything seems off. The whole basement sump pump installation typically takes one day, and you’re protected immediately.
