"Highly recommend!! In 16 years, we have never had a need for a generator. We were told we were on the hospital grid. Well, apparently, those grids change. Over the last year, we have had too many electrical problems with long outages leading us to come to the decision that it would be prudent for us to buy a generator. After doing the research and seeing all the details involved with ordering, preparation, installation, etc, we decided there are too many important details and decided to look for someone to do everything for us. It's incredibly important to know that we came to this decision in December, 2020 (height of generator demand), during a pandemic and during a time of an extreme nationwide generator shortage. While researching, we saw so many people waiting months for a generator from other companies, trying to do everything themselves, waiting for the transfer switch, then an electrician and so on. We figured we would be lucky to have it for next winter. We met with Matt Sanford, he went over everything in detail, looked at the potential sites for the generator and the propane tanks, measured, etc. He could have sold us a bigger generator, but he thought it would be a waste for us to spend extra money on a specific generator I "assumed" we needed. Matt determined the size needed, made recommendations and we, happily, gave him a down payment check. He said 4-6 weeks. I still had my doubts, but here I am writing a review 4 weeks later, because the installation is complete. It is a two-day process. The workers who installed it showed up shortly before the expected time with masks on, were clear and concise, informative, professional and were very courteous of their surroundings including inside the house. In all honesty, I was floored with their demeanor. They completely took me by surprise and it was well above my expectations. When they called to book the installation, I was told the electricity "could be" out for several hours. We planned for several hours. When they arrived, they said it would be an hour or two. It was out for 15 minutes. They do as much as they can in advance so the power is out for as little time as possible, but there can be issues. DO NOT plan that your power would be out for that short period of time. Plan for the worst and hope for the best. The next person, who installs the gas portion, arrived bright and early the next day. He was just as nice, informative and professional as the workers the day before. The communication from the company is stellar. The people they have working for them are fantastic. I cannot say enough good about our entire experience. You WILL NOT be disappointed. By the way, here's something I didn't even know existed until Matt told me about it. Ask about the house surge protector. Even my insurance company had never heard of it. I wish I had known about it when it came out. Also, based on the work involved with the generator, it is comforting to know we are paying them for maintenance, monitoring, etc. In my opinion, this is a complicated machine to install and maintain. They see everything our generator is doing and if something is not right, they'll send someone out before we even know something is "not right". You don't want to be caught in a major outage and have a failing system. You go through the big expense of buying it and installing it, make sure it's taken care of on a regular basis by a professional just like your car, home heating system, etc. I highly recommend this company."

Customers say: True professional

"Dave was recommended to me by a long time friend and I am very thankful. I bought a house that was in need of many upgrades, repairs and additions to the electrical service. His work is phenomenal! He goes above and beyond, by making sure that everything is done correctly, to code and safely. There were many unforeseen issues once he started getting deep into the electrical work on my house and he continuously made me aware and what was needed to fix the issues. I was still living in Florida when the work was done, so all of the work was done "pre move-in" and he was totally trustworthy. I can't say enough about his professionalism, expertise his level of perfection to which he completed all issues in my house. Many thanks to him for making my house electrically safe and meeting all of my needs. I will never hire anyone else but Dave for any future electrical needs I may have. Thanks again Dave, great job!"

"Ken really came through for me in an urgent situation, installing a generator hookup the day before a giant snowstorm when everyone was scrambling. He even went above and beyond and found a great generator for me when most stores were sold out. I will definitely use his services again. His apprentices were also very polite and professional."

"I was looking for an electrician to do a small job. David Lanzillo called within minutes of me posting a search request on an internet site. He came to my home within an hour and provided me a fair estimate for work he was willing to complete within a week. He came with his apprentice as scheduled and was prompt, professional and courteous. I would contact him again and would highly recommend him for any electrical work."

"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 generator repair projects in Hollis, NH

Always start by confirming the pro’s license number, insurance coverage, and experience level. Visit the electrician’s website, scan recent customer reviews, and verify credentials with your local labor department. Request proof of liability insurance and at least two references that you can contact. These quick checks take only a few minutes but go a long way toward ensuring safe, code-compliant work and protecting your home in the event of an issue.

Grouping several electrical jobs into one appointment means you pay a single service-call fee and one set of travel expenses. Instead of asking a pro to return three separate times for outlets, switches, and fixtures, have everything tackled in one visit. The electrician stays productive, and you avoid extra trip charges, often shaving a sizable chunk off the final bill without compromising quality.

DIY electrical work can be dangerous and, in many areas, illegal without a license. One miswired connection risks shocks, fires, or expensive damage. Licensed electricians carry the right tools, follow local code, and know how to shut down power safely before they start. Hiring a pro may cost more upfront, but it protects your home, family, and insurance coverage in the long run.
