    Won't return calls

We used this company a couple years ago and they did great work, we had no issues ... gave them a 5-star rating on that work. Something has changed because when we needed some additional electrical work, we have tried to contact them for the last two weeks. We have left four messages with the answering service and sent an email through their website with NO response or returned calls. We finally gave up and called another electrician who came out the next day, gave us a written estimate for free, and completed the work within 24 hours. Not sure if they have too much work or what, but not responding at all is never a good sign.

    Extremely Happy Customer
By Teresa D

We had a home that had aluminum wiring that needed mitigation before selling it. We had 3 contractor bids from the Referral List, all fantastic companies. What made Tim and his son stand out was not only what he offered in his bid but also his pricing was very reasonable. Like the others he offered a free estimate and meeting him in person was a great experience as he walked me through each step of what needed to be done. Communication for any questions was extremely prompt. His son and he worked as promised on the days scheduled. Follow through was through and the work was quality. We are extremely happy and would highly recommend this company for any electrical work.

    Best Price
By Nancy

Tim and David from Williams and Sons Electric recently came to my home to upgrade my electric panel.They were on time as scheduled, friendly and completed the work as promised. i would suggest them for any of your electric needs. I had priced several companies and Williams was the best price. I will use this company again if the need arises.

    AS Promised!
By Eddie

Tim was very punctual. Did what he said he would do and went beyond my expectations. I doubt I will need any further electrical work now, but if I do, Tim Williams will be FIRST on my call list.

    Great Craftsman
By Jim

Williams and Sons Electric did a great job for me. I had a remodel and they came in and did a complete rehab of the entire electrical system to make it safe. Tim and crew came in under budget and on time. I will use them again! thank you, Jim-

    Outstanding Work!
By David O

I recently purchase a house that needed the service panel replaced and the interior wiring and fixtures upgraded. Tim was quick to contact me after I called his company and arranged a time to be at my house to give me an estimate. Tim quoted a very competitive price and gave me a time frame of when the job would be started and completed. He worked non-stop to complete the job on time and arranged for the inspection. . Tim went above and beyond the scope of the project to insure that my house was wired correctly and that my family was safe. I would definitely recommend Williams and Sons Electric and would not hesitate to use them again for future projects.

By Marc Kay

Williams and Sons Electric are a tribute to their trade. They came out and wired my garage for an industrial welder, which included a new 200 amp fuse box. They also installed various 220 and 120 volt circuits in places where I would be able to expand my hobby/business as it grows. It was absolutely a no fuss or muss job and they had it done faster than I thought possible. Mr. Williams came out for a bid along with 4 other companies. He stood out from them all with his positive attitude and took part in the design of the electricals, plus his pricing got me much more bang for my buck. I will only use Williams and Sons Electric for any and all of my electrical needs. His employees are pollite and honest. I have a bathroom that needs wiring and I shall be calling on him and his employees.

    As Promised
By Eddie Lee

Tim was courteous, very prompt and produced as promised in budget. Can't ask for much more.

    Great Job
By C McCormick

Tim was quick to contact me after I emailed his company. They arranged a time to be at my house (had our main service panel changed, new grounding, and an Excel by-pass meter installed) and showed up on time. He completed the job in the time frame he quoted and arranged the inspection. I would definitely recommend his company.

    Professional, personable and technology current.
By Cathy Hansen

Williams and Sons installed canned lighting in our kitchen and rewired our bedrooms for ceiling lights/fan wiring. While installing our canned lighting they suggested that we use LED lighting with a dimmer switch. Not only are we saving on electricity, but we were really happy with the way the room was illuminated. Williams and Sons gave us a fair price for the work they did, were hard working and very nice in addition. We will definitely use Williams and Sons Electric again.

    The Real Deal
By George Sears

Tim and his craftsmen really care about the quality of their work. They go the extra distance to make sure things are done right. They started the job on time every day and finished it when they said they would. Tim is a good communicator who helped us make informed decisions that guaranteed great results at the end of the project. Tim and his crew are fair, honest and hard working people who do exactly what they say they'll do. It's the old fashioned way of doing business. These guys are simply the best!

    An Outstanding Company to Work With
By andy1906

I am one tough customer. I read Consumer Reports every time I make a major purchase, I listen to Tom Martino – I research EVERYTHING! When I find good service I think it’s important to recognize it so that others like me can make the best decision possible. I can tell you that Tim Williams is an excellent electrician for your job (big or small). He rewired my entire 1906, 1,380 square foot , 2-story home. The wiring was old and dangerous – now not a single strand of old wiring remains. He was extremely reliable, personable, knowledgeable, efficient and above all, honest and sincere. What was at first a daunting and very overwhelming task, turned out to be a fun and interesting experience. Tim surpassed my expectations – and that doesn’t happen too often. If you’re as particular as I am, you’ll appreciate his detailed bio and work experience available on his website. Also, please feel free to email me if you have any questions – I’d be happy to help you make your decision. Tim did excellent work for me and was a joy to work with! Call him, meet with him and you’ll know what I mean. Email me if you have any questions – I’d be happy to help you make your decision. Pros:Highly skilled, efficient, honest, reliable Cons:None
