Cedarhurst Sump Pump Installation Company
Diamond Masonry & Waterproofing LLC has been protecting Cedarhurst area homes from water damage for years. We understand how Long Island’s high water table, storm surges, and soil conditions affect your basement.
Every sump pump installation we complete is designed specifically for your home’s needs and our local conditions. We’re not a franchise following a generic playbook – we’re local contractors who live and work in this community.
You’ll work directly with licensed, insured professionals who respond when you need us most. Because when your basement floods, you need someone who answers the phone and shows up ready to work.

Professional Sump Pump Installation Process
We start with a thorough assessment of your basement’s current drainage situation and water entry points. Every home is different, so we measure water flow patterns, check your existing system if you have one, and identify the best location for optimal pump performance.
The installation involves excavating a proper sump pit, installing the pump and discharge system, and connecting everything to handle your basement’s specific water volume needs. We install battery backup systems so your pump keeps working even when the power goes out during storms.
Before we finish, we test the entire system under actual water conditions and walk you through basic maintenance. You’ll know exactly how your new basement sump pump system works and what to expect during heavy rainfall or flooding conditions.
