About Us

Guaranteed Plumbing is a local plumbing and heating company with passion for our work. We’ve served the entire Philadelphia region for more than 30 years, helping homeowners from Northeast Philly to Chestnut Hill to Montgomery County, PA, repair and maintain their heating, air conditioning and water drainage systems – and we’ve loved every minute of it.

Owner Eric Slifkin got his start in the plumbing and heating business as a 14-year-old apprentice, venturing out with his stepfather to assist with repair jobs in the Philadelphia area. Young Eric developed an instant affinity for fixing things and helping people that remains the heart of his business to this day.

Guaranteed Plumbing is a one-stop shop for all your plumbing and heating needs. We own all our own state-of-the-art machinery, and all our services, from excavation to finishing touches, are performed by our own employees. We do not contract out, so you’ll always know you’re in good hands – our hands!

You can trust us to provide the highest quality work with the friendliest customer service, and you can also trust us to give you a fair price. Guaranteed offers a full warranty and a one-year policy on parts and labor, guaranteed!

As our name suggests, what we promise is what we deliver.

  • Small world, didn’t realize we knew so many of the same people! Thanks a lot for getting our drain clog fixed as my wife was really stuck and we needed it fixed right away. I have seen your trucks around for years and didn’t realize that you did drain cleaning too.
