When you're building an addition, developing a new property, or need to extend your existing sewer line to reach the city main, Sewer & Water Pros handles the entire sewer extension project from start to finish. A sewer extension involves running new sewer pipe from your building to connect with the municipal sewer system in the street. This is common for new construction, home additions, converted properties, and buildings that need to connect to a different sewer main. We handle all NYC DEP permits, excavation, pipe installation, inspection coordination, and complete site restoration. Our crew has extended sewer lines across all five boroughs — through concrete, under sidewalks, across yards, and beneath streets. We use extra-heavy cast iron or PVC pipe depending on your property's requirements and NYC building code specifications.
In Manhattan, our team has completed thousands of sewer extension projects across all 80 neighborhoods.

"Sewer backup on a Sunday night — not fun. Called Sewer & Water Pros and they had a crew at our building within 2 hours. They did a camera inspection, found the blockage, and cleared it that night. Then came back Monday to do a full repair. Saved our restaurant from a health code nightmare."
David K. — Upper East Side, Manhattan
"Water main leak was flooding our basement. Sewer & Water Pros responded within an hour, shut off the water, and had the repair done by the next morning. They coordinated with DEP and Con Ed seamlessly. Their emergency service is the real deal — fast, professional, and fairly priced."
