Scott T.Scott T. ★★★★★ Had an ancient outdoor hose faucet replaced by Sims and Sons Plumbing and they were very responsive and easy to schedule with. Most follow up and scheduling communication was done with the phone line over text message, which was very convenient and organized. The price was reasonable and they stood behind their work as there was a problem initially with the replacement faucet which they quickly resolved with no hassle. Everyone who came to my home was very professional and on time.Frank Yepez C.Frank Yepez C. ★★★★★ The power in our unit went out unexpectedly on a Sunday, once we figured out that the outage was limited to us, we called Sims & Sons. They gave us an estimate over the phone and came out. They gave us an ETA once they were close to our place. They diagnosed the problem in no time and were able to restore power quickly. We will be calling them again to solve other electrical issues as they arise.Response from the ownerThank you, we where happy to help! We take pride in servicing our clients 24/7 for emergencies. We are always here for you no matter when. We look forward to helping again! On behalf of the Sims & Sons family thank you Frank Nicholas N.Nicholas N. ★★★★★ Highly recommend Darrell and Sims & Sons. They provide high quality electrical work at a fair price and you can feel confident that they are not overselling you on what needs to be done. They are very responsive and professional, arriving on time and being respectful of your home.Darrell came out to assess an electrical problem in my bathroom and diagnosed the problem right away, fixing it 30 mins later during the same visit, on the same day. Other electricians who I had contacted had advised that more work was needed on a separate appointment and at a higher cost.Needless to say, I will be recommending Sims & Sons to neighbors, friends and family in their service area.Response from the ownerThank you for this review, We look forward to helping you again in the future! We pride ourself on being honest good tradesmen and practice helping our clients to the fullest of our ability see you next time around. loren G.loren G. ★★★★★ We had an emergency electric issue with our dishwasher after a dishwasher repairman busted the electricity running to it. Andy came to the rescue from Sims & Sons. You could tell he knew exactly what he was doing. Our circuit panel isn’t labeled and he figured out which breaker was for the dishwasher quickly and replaced it (plus labeled it). Then he realized there was a pinch in the wire which caused the problem. Our dishwasher is back up and running now.Mohamed F.Mohamed F. ★★★★★ Sims & Sons is a fine establishment with knowledgeable electrical and plumbing professionals available to help at any time of the day. The owner, Darrel is extremely knowledgeable and kind, taking the time to walk me through a repair over the phone with a genuine desire to help. I was extremely pleased with Sims & Son’s ability to find an efficient solution to my electrical issue on a Sunday evening, all with exceptional customer service. I will definitely be calling them again for my next Electrical/Plumbing needs and highly recommend you do as well!Danny R.Danny R. ★★★★★ Sims & Sons did an excellent job for me. Darrell was extremely helpful and responsive, quick to schedule service, very knowledgable, communicative, fairly priced, and went the extra mile for several things I needed done at my property. I highly recommend them, A+ customer service and work!Kira P.Kira P. ★★★★★ Darryl and team are the best! The whole family (Andy, JJ, Dylan, Slobo, Abel and Darrell) just installed a new EV charger that required power to be pulled from the house all the way to the detached garage. They were thoughtful, thorough, and incredibly knowledgable. I highly recommend them for any scope of work.Katherine M.Katherine M. ★★★★★ Great response time, they sent someone out within the hour to deal with an electrical issue! Exceptional client service!!Chris LChris L ★★★★★ Thrilled with the electrical & plumbing work that Darrell and his team did at our multi-unit property. Starting with a simple toilet repair and kitchen faucet replacement, then some re-wiring and ceiling fan installations in one of the apartments, we were happy with the work and decided to have them do some updates in the coach house.What we THOUGHT would be a simple job became a major overhaul when we discovered cloth-wrapped wiring and deteriorated plumbing throughout the building... and they took the time to explain different options and make sure that the work would be completed within budget, and on schedule. We have outlets everywhere now, and it's great to know that the house is all safe and up to code!Response from the ownerThank you so much for this review, It was an absolute pleasure helping you through this entire process and I look forward to seeing you guys again you guys are amazing! Katherine S.Katherine S. ★★★★★ Troubleshot my microwave issue, efficient, friendly, highly recommended!Cara B.Cara B. ★★★★★ The service was wonderful however I was over charged for services that were not needed. I knew what the issue was, and they still chose to look at my tub...HonkHonk ★★★★★ This is such a nice guy! I really like him! We had a power outage in our apartment unit for about a day and we didn't know what to do. The maintenance guy said our breakers were good and we should call ComEd or an electrician. ComEd said our meter was good, so we should call an electrician. I'm so happy I called Sims & Sons. Sims & Sons said it was going to be $400 for an emergency visit, but told me to send pictures of our breaker and then figured out immediately that we didn't even actually to pay an electrician to come and it was just our breaker in the meter room that needed a switch flipped. To be honest, I don't know much about anything when it comes to electrical stuff, but he explained everything really nice and was super patient even when I was having trouble answering some questions and when both the maintenance guy nor property manager weren't answering. I wish he was my uncle!!! I hope he's very happy! Yeah!!!!js_loader
