Trusted Lloyd Harbor Sump Pump Installers
Diamond Masonry & Waterproofing LLC understands exactly what Lloyd Harbor homeowners face when it comes to basement water issues. We’ve been installing custom sump pump solutions throughout Long Island, dealing with everything from seasonal flooding to emergency pump failures.
What sets us apart is combining masonry expertise with waterproofing knowledge. We don’t just drop in a pump and hope for the best. We understand how water moves through your foundation, where pressure builds up, and how to create basement sump pump systems that actually work long-term.
Every installation gets the same attention whether it’s preventive protection or emergency replacement. Because when the next big storm hits Lloyd Harbor, your sump pump needs to work perfectly.

Professional Sump Pump Installation Process
First, we assess your basement’s specific water challenges. Every Lloyd Harbor home is different – some deal with seasonal groundwater, others face storm surge issues. We measure water flow patterns, check existing drainage, and determine the best location for your water sump pump system.
Next comes the installation itself. We excavate the sump pit to proper depth and specifications, install high-quality pumps designed for Long Island conditions, and connect discharge lines that move water safely away from your foundation. All electrical work meets code requirements with proper GFCI protection.
Finally, we test everything thoroughly and walk you through the system. You’ll know how it works, what maintenance it needs, and how to spot any issues before they become problems. We also discuss backup power options because storms often knock out electricity right when you need your sump pump most.

Complete Basement Sump Pump Solutions
Your basement sump pump installation includes everything needed for reliable operation. We provide high-quality pumps rated for Long Island’s water conditions, properly sized discharge piping, and check valves that prevent backflow during heavy rain events.
We also handle the details that matter long-term. Proper pit construction prevents sediment buildup that kills pumps early. Discharge lines route water far enough from your foundation to prevent re-entry. Electrical connections use appropriate materials for wet basement conditions.
Many Lloyd Harbor homes benefit from dual pump systems or battery backup installation. We’ll discuss these options based on your specific situation – not because we want to sell more equipment, but because some basements genuinely need extra protection during severe weather events that are becoming more common on Long Island.
