"We recently bought a new home and needed some electrical work done. We contacted RaLo rather late one evening when we had issues with installing our new programmable thermostat, surprisingly someone answered the phone and said they could get someone out the next morning. Mike showed up on time and after discussing the issue with my husband, he went right to work and had us up and running in no time.
Our new home has an unfinished basement and while we plan on finishing it we know it might take some time to fit in the budget, in the meantime we decided one outlet was not enough and decided to get some more installed. Based on his previous work, we didn't hesitate to call RaLo and schedule the work.
Mike showed up right on time and after expaining what we wanted done in our unfinished basement, we discussed and he explained that most of the work we requested should wait until we finish the basement otherwise it would just be a waste of money because it would need to be redone once all the walls went up. We agreed on a temporary fix that we were very pleased with and he went right to work.
Mike is very personable and professional which my husband and I really appreciate. We also like to support local businesses and are very glad to have found a great electrician we can rely on to get the job done. We are extremely pleased with RaLo's customer service, quality of work and price.
We plan on using RaLo for several other projects in the very near future.

"I hired the Three Brothers service to install an attic fan in our home. Augustin and the guys were on time, very professional, and explained the entire process. There were no surprises and work was knocked out in no time. Outstanding service and experience."

"The work went great. A representative looked over the situation ( a 3 story townhouse), decided it could be done and gave us a solid price. The two person crew who did the work were punctual, efficient and neat in their work. The detectors and wiring was installed with no damage to the paint. The job took them about 3 hours. My wife and I were very pleased."

"The electrician Antoine was outstanding. He installed the video doorbell fast and also helped with setting it up with my phone. I would highly recommend All About Sound & Video. I also recommended them to Simplisafe for the Washington D.C. area."

"Mr.Tes from Metro communication and cabling done a very fantastic job both in internet cabling and security camera installation. He was always on time and very professional. the first appointment Tes give us different option on how to wire the internet cable and the security camera installation. once he started the work he was always on time and finished the project a head of the schedule. we are very happy by the quality of his work and professionalism. our security cameras are very much covering all angles needed as well our internet system became very fast and reliable. I recommend tes for any small or large projects."
