The New Castle Plumbing Landscape

New Castle's historic homes are the defining plumbing challenge, many carry galvanized, cast-iron, and lead-era plumbing, and their age and character call for careful repiping and lead service line replacement, now driven by federal lead-pipe rules. Many also heat with boilers and radiators, which we service and replace, and the newer neighborhoods around town have modern copper and PEX.

New Castle's low-lying, riverfront location means basements with a higher water table, so reliable sump pumps and basement-backup prevention matter, especially during heavy storms, and older sewered neighborhoods can be prone to backups. Delaware's hard winters bring frozen-pipe risk to the exposed runs historic homes so often have. We work carefully and cleanly to protect these irreplaceable old houses.

Kathleen Weir

Called at 8:30 - Benjamin Franklin Plumbing arrived at 11:15! Problem solved by noon! Friendly and competent service!

Saqib Baig

I wanted to share my appreciation for the excellent service Brandon and his team provided. Brandon arrived on time, responded quickly, and handled the work with professionalism, friendliness, and care. What stood out most was the speed and convenience of the service. Brandon assessed the leakage damage, cleaned the spout, scraped away the old caulk, reinstalled the area, and sealed it properly for waterproofing. Please extend my thanks to Brandon and his team for their reliable work and excellent customer service. I would definitely recommend their service and will call again for future needs.

Whitley Bilek

The owner is very detailed and does his research! He wants to ensure everyone gets the best possible. Through his top of class hiring and extensive attention to detail, the Madison area has a great option with Benjamin Franklin Plumbing for all of their plumbing needs!

Cheri Carver

Keith came promptly, worked quickly but we paid $709 for a water shutoff, and a small piece of PVC pipe under our sink that took 40 minutes to do. $210 of that was because it was an emergency visit.

Brenda George

Chase was exceptional!! Jared was so helpful as well!! This company came out to check our heating and cooling systems, clean our hot water heater, and patiently answered a bunch of our plumbing and duct-cleaning questions. As owners of an aging home, we truly trust them and deeply value their expert opinions on what updates we need. The level of professionalism cannot be surpassed! From wearing booties so they don’t drag dirt into the house to sending texts with pictures of the technicians before they arrive, every detail made us feel safe and cared for. We trust them completely with our home, will definitely continue doing business with them, and are already recommending them to all our friends. They are simply the best in the area!

Cynthia V. Bell

The service was timely and professional. I really appreciate that Chuck treated my home with respect. He not only wiped his feet, but he put on booties to protect my floors. He did a thorough inspection before he gave me the estimate for the service needed. Because of his courteous explanation of what was needed to get the job done correctly, I would highly recommend him.

New Castle Plumbing FAQs

My historic New Castle home may have lead pipes, can you help?

Yes. Older New Castle homes can have lead service lines or lead solder. We locate, test where appropriate, and replace lead-era lines and piping per current federal lead-pipe rules.

Do you service boilers and radiators?

Yes. Many historic New Castle homes heat with boilers and radiators, and we service, repair, and replace these systems.

Does my riverfront home need a sump pump?

Low-lying, riverfront homes are more prone to basement moisture and flooding, so a sump pump with battery backup is often wise. We assess and recommend.
