Gates and Sliz Electric is a commercial and residential electrical contractor serving New Hampshire and Massachusetts, with the company site listing service upgrades, repairs, lighting, generators, EV charging, pool and hot tub electrical work, fire alarms, and security systems. The site reports a 2023 company history, while BBB lists Gates Braunius as owner/master electrician. The track record is strongly positive across 14 reviews from 2023 through 2025, with a 4.8-star Google rating from 20 ratings and an A+ BBB grade. Homeowners describe lighting and fan installations, faulty-wiring repairs, panel and room-renovation work, prompt responses, clear communication, neat cleanup, reasonable pricing, and professional results. Before booking, confirm the current license details, project scope, and service area for the specific job. BBB shows the business is not accredited, and its six-year business-duration entry differs from the website's 2023 history statement.
This is the easiest review I’ve ever written! I had Gates and his guys put in under cabinet lighting, fix my porch light and install a new ceiling fan in the family room! They also changed the light in my screened porch - it looks awesome! They did an amazing job! They are neat and clean up the whole working area. They also put a decorative piece around my garage lights outside! It looks awesome - I never would have thought of it! I can’t say enough about this company except that you’d be missing out by not hiring them! They really go above and beyond…they were recommended to me by my cousin who also had them do some work at her house! Totally satisfied! Way to go G & S Electricians…you are definitely ours now! Oh and they are not expensive at all!
Gates and Sliz came out to address some faulty wiring. Addressed the issue, with informative and professional service. They had the semi-working and unsafe wiring removed, and ac unit power was restored. A+ job for sure. Quality service, and exceptional team of electricians.
They installed my kitchen lighting, under cabinet lights, and a few plugs and all for a very reasonable price! Very friendly, fast, and knowledgeable. Would recommend!
Mike and gates are the best electrician ever Always do a great job and they have too much knowledge about what they do Gays are great
The guys did an awesome job on reworking the wiring on a room renovation. From start to finish, they exceeded all of my expectations. I would highly recommend them to anyone.
