DiMar is quick to execute on your electrical needs. They untangle a rats nest, get it up to code, and for an affordable price. We have an old historical home and they were able to fix everything to keep it authentic but also add new lighting to brighten the rooms. I’m not sure why you’d look for a sparky anywhere else

Mark has done work for us for years - from working on our home’s electrical panel, wiring for an HVAC system, to installing new light fixtures and ceiling fan’s, he’s our first call for all things electric. We have an old home and there’s no one else we trust to get the job done. Marks extremely reliable and always does things the right way.

I highly recommend DiMar Technology LLC! They did an excellent job wiring our basement and installing outdoor lighting, and also quickly diagnosed and fixed an electrical issue with our pool. Every step of the way, they were professional, knowledgeable, and efficient. The quality of their work really stands out — everything was done neatly and works perfectly. On top of that, their pricing was very fair. It’s great to find an electrician who combines skill, reliability, and affordability. I’ll definitely call them again for future projects!

We hired them to install our landscape lighting, and they were very easy to work with. While our mason was onsite, his team prepared the landscape then DiMar handled the lighting installation. They took the time to walk us through different lighting options, which we found very helpful. On installation day, their team was very efficient. We’re very happy with the results.

Mark is the only person I would trust with any work in our home. His expertise spans everything from lighting and media consoles to rewiring the electrical panel, and the quality of his work is exceptional both inside and out. He is highly professional, reliable, and delivers outstanding results at a fair and competitive price. I would recommend him without hesitation.

They are as good as they come. I’ve used DiMar numerous times and they always do a great job. Easy to talk to as professional and kind as you could want. Good local guys who couldn’t be more reliable. I’ve recommend them to a few people now and they’ve all said the same exact thing. Highly recommended on my end.
