Best Home Addition in Jacksonville FL

Extended service to detached building. Ran wire, installation of new breaker box, wired for a new switch, light and GCFI outlet. Didn't break the bank, excellent work, fast, very courteous and professional. Will definitely use again!

I highly recommend GNH. I had a small residential job handled and the first 3 companies I called couldn't schedule for a a whole week out. My irrigation was on the tripped circuit so my grass would be long gone by then. I called GNH and they were able to come out the same day I called. Doug was professional, explained what he would do and how much it would cost. They diagnosed the problem, fixed it, and did it for a very fair price. Friendly...Fast...Fair, I'll call them for all my electrical problems in the future!

I would like to thank you guys for sending Jerry Lord to do the work at my home. He was very friendly and very efficient in his work. Please, keep up the good work and I will continue to call on you.

Thanks,
Rev. Gary Kitt

I used them to repair an open ground wire which required a lot of detective work by the electrician. He was able to find the problem and fix it quickly. They were on time and were professional and friendly. The bill was fair and I will be using them again.

I don't have anything against smoking pot, but I would if it was my employees driving around with their girlfriends in my company vehicles smoking out in the open like yours do (:

We recently moved to Jacksonville and had several electrical projects that needed to be completed in a timely manner on our new home. Nick and his team completed them on-time and on-budget. No change orders, no surprises, and no headaches. I had an electrical journeyman's license in two states prior to moving here and I have been extremely pleased with the quality of work, and with the accuracy of the bids. I highly recommend Nick and his team, and will continue to reach out to him as our first choice for all projects going forward.

Mr Thayer was super friendly, did Fantastic work, and was quick to address our issues! We will 100% use him and the company again for any of our future needs!! Thank you so much!!

These guys did a great job wiring my office building. Thank you for your level of professionalism, quality of workmanship and great value.

We can't say enough good things about this company. They had to trench electrical out to a pool pump and several other outside and inside outlets. The crew was most importantly knowledgable, and professional, friendly, respectful, communicative, and on time. We will definitely be using them again.

During the process of purchasing our home, we discovered that the house we wanted had cloth wiring and ungrounded power throughout. This was a huge set back. As of now, home owners insurance companies will not insure homes with cloth wiring. We were nervous this would hold up our closing process.

Luckily, I was given Mansfield’s info by a coworker. They came out the next day for an assessment.
At that point, I had 3 other electrical companies come out for evaluation and quote.
Mansfield was the cheapest and the least invasive. The other companies told me they would need to cut thorough my concrete-plaster walls - which I would need to repair myself. This was something I didn’t want to do, but I was starting to believe this was my only option.

The following week, Mansfield started the project of switching my cloth wiring out and grounding my outlets. They were able to go through my attic to replace the wiring instead of cutting through the walls.
They even added 15 new outlets in and outside our home, as well as adding a flood light. The project took about a week. During this process, Mansfield was timely, kept me informed, and even cleaned up after themselves after everyday.

Mansfield was able to complete the project before we even closed on the home. I’m so incredibly with their quality of service! Their work was the reason why we were able to purchase our home and obtain home owners insurance. Everything works perfectly! I would highly recommend their services to anyone and I will definitely be using them again for any of my electrical needs.

I was extremely impressed with their customer service. Jessica with their office was amazing as was the gentleman who repaired my grandma's electrical issue. They came out and fixed it the same day which I greatly appreciated. I will definitely use them in the future. Class act.

The Dalie company is by far the best I’ve had to do my electrical work. Over this year they’ve done everything from hanging a fan to creating a 240 outlet for charging my car. They’re always thorough and professional. They’re on my very short list for all my electric related stuff.

Matt was quick and squeezed us in at the end of the day the day we spoke. Had some wiring that needed to be brought up to code to close on our sale.

Aaron is very professional, and a good worker. He assisted with hanging pictures in my home. He did a great job and I would definitely recommend him.

We had a hard to diagnose electric problem after the hurricane. They sent out 2 technicians, who filtered thru my wrong assumptions, and found the real problem.
Price was very reasonable.

Great service
