"I sent a request quote to Safe Streets and my phone was ringing within 1 minute. Impressed with the quick responsiveness. They are partnered with ADT which made our choice to get our alarm system through them a no brainer."

"A lightning strike caused our security system to become non-functional. UGSS assessed the system, replaced the main unit, control panels, door sensors, cameras and checked that the wiring and sensors worked througout the house.
UGSS sent out Andy to do the original assessment and then the first replacement visit. Due to the severity of the problem, multiple visits were necessary, which we agreed was appropriate. Andy did an awesome job with the installation and programming and taught us how to operate the new system. The remaining visits when similarly as well and we are happy with the work performed, the attitudes of the installers, and the site preservation/clean up. Ordering and scheduling through the main office was accurate and the team left informative voice mails when they couldn't reach us. Only suggestion we would make is to follow up directly with the office if you make a request of the technician. Between appointments, we realized that the technician had not remembered to let the office know of an additional item we needed to be ordered. It took longer then to complete the full job.

"The guys arrived exactly at the prearranged time. They informed me that the work would take longer than the '2 man hours' that I bought through the Angie's List Deals before they began the job - which I appreciated. They were on task and professional the whole time. They explained any problems they encountered while re-installing the old light fixture - need new bulbs. They cleaned up any mess they made at the end of the job. Rates and cost of supplies were reasonable. I WILL BE CALLING THEM BACK FOR ANY OTHER ELECTRICAL WORK IN THE FUTURE.

"Father and son team came and installed 6 LED recessed lighting and a dimmer. They explained everything well and were honest with their opinion. There was no sense of upselling and the work was done professionally and they cleaned up after the work was done. Would definitely hire again. Support small businesses!"

"Excellent customer service AND installation team. We purchased a whole house generator from Long and, even though there was a bit of a wait because the manufacturer was backed up, the Long people stayed in touch and delivered the generator took great care during the install. I would definitely hire them again for my electrical needs."
