Did wonderful work. Came out quickly to do free estimate and was back a few days later to to the work. They adjusted to surprises and performed the task with utmost professionalism and friendliness.

  • Tim and David were great to work with. The quote was reasonable, they showed up promptly and got to work. Everything was done to the highest standards, and it’s good to know that if I ever have any questions or need future work done, they are just a phone call away.

    Mary Ann Nimmo
  • The experience with Williams and Sons Electric and the proposed lighting project was painless. Tim was easy to work with and allowed things to play out without pushing to make things happen. Quickly assessing the lighting issue, sketching a rough drawing of the proposed fixture layout, established project timeline and start date, in addition to the cost proposal. Tim and his son started on schedule, completed project within the established timeline with outstanding precision and level of performance. Would definitely use Williams and Sons again!

    John Winterroth
  • Had Tim, David, and Rick over to complete a few electrical jobs. The team was punctual, courteous, and efficient---exemplary professionalism overall. They ensured complete satisfaction throughout each job and offered fair and honest pricing. I will look to Williams & Sons Electric for my family's future electrical needs and encourage others to do the same.

  • They did a excellent job. I will give them 5 stars rating.

    Larry Hankins
  • Excellent work completed on my house; electrical work done efficiently, clean up was great,.
    I will have them out again to change out my service panel.
    Nice Job!

  • I've been meaning to write this recommendation since September when I first had Williams come work on our home. Their work has been so amazing, and Tim and David have been so professional, I just keep having them back to work on other parts of the house. I am so impressed by all their work. Tim, David, and their apprentices have all been incredibly courteous of the fact we both work from home and still provide top-notch work. They bring up any issues found while working and offer to fix those too or if not just make us aware and explain the process. They have been as competitive price-wise as any and I already have plans for them to rewire the remainder of our house. I recommend them to anyone who asks for a reliable and attentive electrician.

  • Please use Williams and sons electric. I used them and they are awesome

  • Excellent experience. Quick response after storm damage. Easy to work with schedule around tree/crane service. Nice clean install. Family-owned company!

    Warren S.
  • 2. Due to a recent late-May snowstorm, a neighbor's tree branch came crashing down, not only taking out his power but damaging our power lines as well; our service was connected to a common utility pole in the alley. The impact was so severe that it actually bent the top of the pole (like a bow) enough to yank our lines (and supporting cable braid) out from the main electrical mast (steel pipe) on the roof. In the process, the sudden strain also bent the mast itself--which had to be replaced along with our entire electrical service entrance panel.

    Tim (owner Williams and Sons Electric) promptly showed up on the morning after our initial phone contact, with a reasonable estimate. We found him to be beyond friendly and helpful, from our first meeting throughout completion of the job. Tim's excellent work ethic, quality of work and professionalism spoke for itself:

    Punctual--set timeline expectations and followed up as promised.

    Thorough--paid attention to every little detail and replaced a couple of items that weren't in his quote...for no extra charge. Tim and his son, David, even relocated and re-secured a cable TV line that was coming loose as a result of the storm. They also removed an old phone line that was no longer in use (I needed this done anyway because it was in the way of a future deck awning installation).

    Overall, the work performed was professional, tidy, and I could not imagine a better, more qualified electrical contractor for the job. Highly recommended!

  • The work was completed to a standard that far exceeded my expectations!

    Happy Homeowner
  • Friendly and fast response time. Came out and gave me a quote but was a little more on the pricey side.

    Mindy C.
  • I highly recommend them to anyone seeking an honest and skilled electrician.

  • Five Stars!

    Debbie Rippe
  • Tim and his son David rewired our kitchen for a kitchen remodel two weeks ago. They did a great job at a very reasonable price. In fact, their price was $1,000.00 less than a competitor's bid. We will be using them to finish our basement in the near future.

    Mary M.
  • We will be using them to finish our basement in the very near future.

    Happy Homeowner
  • I called Tim to install an old breaker box and also install a new outlet. The service provided was excellent and the install of the new outlet exceeded my expectations. He was very professional and actually cleaned up a few items that weren't necessary and fixed another outlet that i hadn't even mentioned. I would highly recommend these guys for any electrical needs you may have.

    Carig M.
  • Very professional and quality job for my house. I highly recommend this company for whatever electrical you may need done. Insured and prices reasonable, knowledgeable, and conscientious.

    Barb S.
  • I found Williams and Sons on Yelp and called them to fix an electrical issue at my place. They were one of the only companies I called that was able to help within a 24 hour period, which was a must given that the electrical issue was a fire hazard. When they arrived I was super impressed by how friendly and knowledgeable they were. They diagnosed my problem immediately and fixed it within a couple of hours. Their prices seem very reasonable and you could tell they were efficient at getting their work done. I will definitely use them again in the future!

  • Tim and his son David did a great job on our kitchen remodel. We will be using them for our basement wiring in the near future. We will recommend them to all our friends. Great job, great price! Lawrence McManus

  • I am one tough customer. I read Consumer Reports every time I make a major purchase, 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 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.

  • Tim Williams did a service upgrade for our home. He did a great job and was very nice and helpful. We will definitely call them again the next time we need help with an electrical issue. Pros: On time, professional.

    Jeanieln
  • What a delightful experience! We dealt direct with Tim who was polite, courteous AND very professional. He worked quickly, knew exactly what he was doing and we were VERY impressed with the finished job! Pros: FAST, FAST service and VERY speedy return calls! Great experience! Cons: NONE!

  • 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 hardworking 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!

    George Sears
  • Tim Williams and his crew were wonderful to work with. Tim gave me a straightforward bid and completed the project on schedule. Add'l work involved code and safety and fixture replacement. Work was done efficiently and more reasonably priced than any other contractors.

    J. English
  • 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.

    Cathy Hansen
  • 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.

    C. McCormick
  • i spoke to owner Tim Williams regarding a whole lot of work ranging from a new panel box, to simple plug rewiring issues and he was extremely fair in his pricing and did everything we went over and more, -these guys are the kind of guys that promise less and deliver much more. i would recommend Williams And Sons Electric for any job! They are just simply put -fair, honest, hardworking and dependable. 5 Star service!

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

    Eddie Lee
  • 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 polite and honest. I have a bathroom that needs wiring and I shall be calling on him and his employees.

    Marc Kay
  • 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 ensure 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.

    David O.
  • We had kitchen can lighting installed this week by Tim. He has a great personality coupled with fantastic experience. He is a great electrician who also gives good suggestions...all of which were appreciated! Thanks Tim we love our lights!

    Shannon Rhodes
  • 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.

    Nancy
  • We were very pleased with the job. we had re-wiring done and a new breaker box installed in a very old home. they did the job in less than ideal conditions since the home was old, access to areas needed was difficult. yet they did the job with professionalism, completed it in time specified, with as little inconvenience to us as possible. we will use again if needed and will refer to others. they definitely earned their money.

    Corinne D.
  • Tim and his son David were wonderful. Tim was always on time for appointments and helped me through numerous versions of his proposal until we figured out how to get the biggest bang for my buck. His prices are reasonable and his work is excellent. I have a 3-story brick home built in 1892 and it wasn't an easy task to work on my home. I will call him for all my electrical needs from now on.

    Julie C.
  • I contacted Williams and Sons electric because the other electrician I used in the past was booked solid until mid-December. Tim within a matter of hours Tim was at my home and provided me with a reasonable quote to complete two jobs. Tim was professional and courteous and had the job completed fairly quickly.

    Levi D.
  • Tim wired up my garage a couple of months ago so I could turn it into a shop. This included multiple heavy amperage, 220v circuits and several 120v circuits. This also included upgrading my panel to accommodate the larger draw. He did a great job with it, and it passed inspection without a problem. I had called several contractors and gotten several bids. Tim was right in the middle, in terms of pricing, but I chose him because he was responsive to questions, showed up on time (every time, both during the bid and on the job), and took the time to understand the kinds of machines I would be running. He also helped hammer out issues with XCel, making sure they were happy with what we were doing. He did miss one circuit on the order (just a dedicated outlet), but since there was a quite a few, I don't really fault him for that. When I pointed it out to him, he apologized and wired it up on the spot.
    Overall, I'm happy with the service I got with Tim, and I would highly recommend him to anyone who is looking to get residential work done. If I have more work in the future, I won't hesitate to use him.

    Max C.
  • 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
  • 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.

    Eddie
  • We are absolutely thrilled with the work that Tim did. He was professional, curious, and quick to arrive and we will definitely be using this business for our future electrical needs. As a real estate professional I come across many contractors and this one is fantastic.

    Kevin D.
  • Where do I begin! This was such a refreshingly pleasant experience. Tim was on time, friendly, honest and best of all explained things in a way you can understand. We bought a house that was flipped about a year ago and in our contract the electrical was all supposed to be brought up to code, obviously it wasn't. Tim fixed it all perfectly and went above and beyond to wright a report for us to take to the seller. You really don't need to look anywhere else. Give this family owned company your business. They deserve it and they will get the job done right, right on time and on budget.

    Madison G.
  • Extremely responsive and friendly, got me in quick. Tim came out and provided me a quote on a new electrical panel and GFCI receptacles. He was friendly and knowledgeable!

  • Tim and David at Williams and Sons Electric are great. They showed up on time, did great work and are very friendly. We had a new 200 Amp service installed at our new home along with some additional work adding GFCI duplex outlets, updated dimmer switches and some other work. I highly recommend them to anyone seeking an honest and skilled electrician. Thanks Tim- great job!

    Tom C.
  • Tim and David are amazing. They were very quick to give me a quote, prompt to work, and completed everything in a timely fashion. A detailed written quote was given, as well as different options for completing the work. They listened to my needs and offered suggestions without being pushy or making me feel like they were trying to "upsell" me. Some things took a bit more time/materials than they expected, and I was given a new quote with the exact changes and the reasons for them. The work was completed to a standard which far exceeded my expectations. I will absolutely use these folks again for all my future electrical needs.
