Most homeowners should not repair a broken light switch themselves. Switch problems can involve loose connections, overheating, or tripping circuits that a licensed electrician must diagnose. If you notice buzzing, flickering lights, shocks, burning smells, or warm/discolored switches, stop using the switch and call us. Our licensed and insured electricians handle code-compliant repairs, required permits, and final testing. Same-day and 24/7 emergency service are available for urgent switch issues around Greater Boston.

You can replace a simple outlet, but the safest, code-correct result comes from a licensed electrician. Our team handles permits, code-compliant installations, load calculations, and final testing. We install GFCI outlets in wet areas; upgrading to GFCI in your kitchen or bathroom is a great idea. If you notice buzzing, burning odors, shocks, warm outlets, or frequent trips, stop and call.
- Turn off the breaker and verify power is off with a tester.
- Use GFCI in kitchens/bathrooms.
- Stop if wires are burnt or aluminum. <br/>

You can, but the safest and most code-correct way is to have a licensed electrician install the GFCI. GFCIs must be wired to the correct LINE/LOAD terminals, located properly in wet areas like kitchens and bathrooms, and verified with a tester. Our licensed team handles permits, code compliance, load checks, and final testing. We offer same-day GFCI installs and repairs in Quincy and nearby towns.
- Turn power off.
- Match LINE and LOAD.
- Test using the GFCI buttons.
