Can I fix a leaking pipe myself using epoxy putty or tape?

Yes—epoxy putty or pipe repair tape can buy short-term time on a small, slow seep, but they are only temporary patches and not a lasting or code-compliant repair. Most leaks come from failed fittings, corrosion, or cracked pipe that require a proper fix like replacing a section of pipe or the joint. A practical field truth: if the surface isn’t perfectly clean and dry, these products rarely hold once pressure and temperature cycle back up. Our licensed plumbers handle these repairs for homeowners across the Boston area, including Dorchester. Repairs we perform are backed by a 2-year warranty, extended to four years for Priority Plan members.

Use this quick guide:

• Reasonable stopgap: faint sweating or a pinhole on low-pressure line you can fully dry and depressurize.
• Skip DIY and call: active spray, corroded or cracked sections, repeated leaks, or wet walls/ceilings/slab.
• Next step: shut off water, relieve pressure, dry the area, place the patch, and schedule a permanent repair.

Always shut off power if water is near electrical and avoid standing in pooled water during any attempt.
