When water starts seeping through your ceiling, dripping down your walls, or pooling under your cabinets, you've got a plumbing emergency. Large amounts of water typically indicate a burst pipe, one of the most common reasons homeowners call emergency plumbers. The real danger isn't just water damage, when water contacts electrical wiring, you're looking at short circuits and potential fires, plus unnoticed leaks create mold and mildew that cause serious structural damage and health risks, so contact James A. Dalelis Plumbing & HVAC immediately.
If your water heater is leaking, smells like gas, or simply stopped working, you're dealing with a potentially serious issue that requires immediate professional help. Water heater problems don't fix themselves, waiting only makes the problem worse and more expensive. Reach out to James A. Dalelis Plumbing & HVAC right away for emergency plumbing services.
A severely overflowing toilet creates the same water damage problems as leaking pipes, except it comes with expensive repairs and mold growth that requires extensive remediation. Turn the shut-off valve behind the toilet clockwise immediately, or turn off your home's main water supply if that doesn't work. Once the water is off, call James A. Dalelis Plumbing & HVAC for emergency plumbing services.
If water is flooding into your home, a pipe has burst, or your drains suddenly stop working, you are likely facing a plumbing emergency. In these moments, staying calm and taking a few fast steps can prevent major damage. Here is what to do right away:

Fast, efficient, and professional. I went to turn my heat on and realized my boiler wasn’t working. It was a Friday before a long holiday weekend but James had one of his guys there first thing Monday morning and my heat was back up and running in just a few hours! Thank you so much!! Highly recommend
Met with me on short notice and took the time to talk about all options, but brief and to the point.
Helped me make a better decision.
Went above and beyond so the work got done in a timely manor and we're very satisfied with the results.
Thank you, James & Crew.
Excellent service. Responded quickly to confirm my appointment and the work was completed quickly the same day. We will be using this company for our yearly heating maintenance.
I had a great experience working with James and his team to install our new boiler and water heater. He worked to understand our needs, gave us solid advice, and provided a competitive bid with no extras or upsells (and no BS!). His work was very professionally done, and it was obvious that he took great pride in his work and in providing the most useful components. He also took the time to explain the work, how the equipment worked, and made sure the settings were what we we were looking for. All in all a great experience, and we will be working with him again.
