"Very professional, clean and easy to work with. Marty dug a trench for underground wiring and gas line taking care to preserve and put back the landscaping in the path of the trench. Installed the panel for the critical service item identified and helped with finding those circuits on the current panel. Quoted several options that were helpful."

"George was great. He was responsive, informative, fair, and even got someone else to eventually pay for the work he did! Can not beat it!The electrical panel at my house shorted out and we were without power. This is especially difficult for my family because we have two children and need electricity to get water. We called him the morning it happened, he came out that night to look at it, and by lunch, the next day we had a new panel and power was back on. George also let us know that our panel failed because of faulty workmanship on the part of the utility company and that we should approach them for reimbursement. Our homeowner insurance told us that the utility would never pay and to file a claim. Our deductible was half the total cost of the project and we did not want our rates to go up when we renew. So with George help we submitted information to the utility and requested reimbursement. In less than a week they agreed to reimburse us for the full amount of the cost to replace the panel. They even covered the permitting fee. It was a thousand times easier than I would have ever guessed.We would not even have known it was an option to the hold the utility company accountable, or what information we would need to prove our case without George help. Hopefully nothing ever goes wrong again, but if it does we will definitely hire George again."

"Arete Electric did an outstanding job on my kitchen and basement after I experienced an under sink burst filter which occurred in the middle of the night… it was a flood. Tommy and his team were extremely reliable, skilled, flexible and simply a pleasure to deal with. A lot of work was needed due to differences in code from when my kitchen was built until now. They also were able to install undercabinet lighting at the counter level and floor level and cleverly hide electrical plugs so not to as interfere with the aesthetic of the kitchen . I highly recommend!!"

"Electrical & Security Solutions are the best! I have needed their services more than once to replace lights, a ceiling fan and also to install a new electrical box and breaker for our garbage disposal. Tyler promptly responded every time I called and he and Casey are both friendly, efficient and skillful. Aside from the excellent service, the qualities I appreciate the most is honesty for what work needs to be done and how Tyler is also very budget consciousness."

FAQs for electrical wiring or panel upgrade projects in Sandown, NH

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
