Emergency Electrical Services We Provide in Hanover
Our team responds to a full range of urgent electrical problems for both homeowners and businesses across Hanover. Every on-site evaluation addresses the immediate hazard and its underlying cause. We don’t apply temporary fixes where a lasting repair is the right answer.
What we handle on emergency calls:
- Power restoration after sudden outages
- Panel and breaker failures, including burning smells from electrical panels
- Sparking outlets and signs of overheating
- Damaged or exposed wiring
- Surge protection assessments and repairs
- Storm-related outage response for homes and commercial properties
- Short-term stabilization while full repairs are scheduled
For businesses, an electrical failure affects operations directly. For homeowners, a tripped breaker or sparking outlet can escalate fast. Either way, we arrive ready to diagnose accurately and restore safety.
Why Hanover Homeowners & Businesses Call Us First
Matthew Carr’s Master Electrician credential isn’t just a license. It reflects a higher diagnostic standard than a general electrician or a national referral network. When we assess an emergency, that depth of training shapes how quickly we identify what went wrong and what needs to change.
We’ve spent more than two decades working on South Shore properties, which means we know Massachusetts electrical code, local permitting requirements, and how regional weather and housing age affect electrical systems. Our electricians are clean-cut, respectful of your property, and equipped with advanced diagnostic tools to get the job done right.
As an Authorized Lutron Installer, we maintain a level of technical training that carries across everything we do. We also work alongside trusted contractors for audio, visual, surveillance, and alarm services when a job calls for it. Free estimates and same-day availability remove the two biggest stressors in any electrical emergency: not knowing what’s wrong, and not knowing what it will cost.

Warning Signs That Need a 24-Hour Electrician
Some electrical problems can wait for a scheduled appointment. These can’t. If you notice any of the following in your Hanover home or business, treat it as an immediate call to action.
Don’t ignore these warning signs:
- Burning odors from outlets or electrical panels
- Exposed or damaged wiring
- Sparks or arcing from any outlet or fixture
- Breakers that trip repeatedly and won’t hold
- Flickering lights across multiple rooms
- Hot spots on walls near outlets or wiring runs
- Overheating ceiling fixtures
- Discoloration or scorch marks on outlet faceplates
- Loss of power on one side of the home
- Buzzing sounds coming from outlets or the panel
Electrical problems rarely stay contained. What starts as a nuisance can escalate to a fire risk or a panel failure, and unresolved faults often drive up energy costs as faulty circuits draw excess current.
Hanover & South Shore Electrical Conditions
Hanover sits in Plymouth County, where coastal exposure means Nor’easters and summer storms are a regular part of life. Each major storm cycle stresses panels, breakers, and surge protection. Properties that haven’t had an electrical inspection after multiple storm seasons may be at risk for a wiring fault or panel failure during a hard outage.
The South Shore’s housing stock adds another layer of complexity. Older homes may still have fuse boxes, ungrounded outlets, or knob-and-tube wiring, while modern commercial properties operate on entirely different systems. Both sometimes exist within the same building. Our team has worked on South Shore properties for over 20 years and has seen this range firsthand, which means we know how to work safely within it.
How to Prepare Before We Arrive
While you’re waiting for our team, a few steps can limit further damage and keep everyone safe.
Steps to take before your electrician arrives:
- Turn off affected breakers or unplug devices if you can do so safely
- Clear access to panels, outlets, and the area where the problem is occurring
- In multi-unit or commercial buildings, notify occupants or staff so the area stays clear
- If you smell burning or see smoke, step outside and don’t re-enter until the technician confirms it’s safe

"I cannot say enough about my experience with MJ Carr!!!"
Matty quickly responded and came by to evaluate the project and got me a quote right away. He worked to accommodate my crazy schedule. Most impressively though he got the entire project done in half the time and almost half the cost as the original quote! The work is immaculate, and I’m sure redoing the electrical system in a 200+ year old house was no easy task. Thank you so much!
