Can you fix a water leak yourself safely?

You can safely fix a very small plumbing leak yourself only when it’s fully visible, slow, and you can shut off the water. Hidden or pressurized line leaks spread fast and should be handled by a licensed plumber. G&C Plumbing & Heating uses advanced, non-invasive leak detection to pinpoint the source and repair with minimal disruption. From our work around Milford, freeze–thaw swings can turn a pinhole into a burst overnight.

Stop DIY and call a pro if you notice:

• water near electrical
• ceiling sagging or walls bulging
• hissing in walls, hot spots on floors, or a spinning meter
• leaks at the water heater, main shutoff, or in a slab

If you try anything, close the nearest shutoff, open a faucet to relieve pressure, and avoid power near wet areas.
