All reviews for Cornerstone Electrical Services, LLC

Professional and excellent work!

Alex was excellent and professional

I will keep your outfit in mind for any other work and pass on your name .

Cornerstone Electrical helped me get my location ready for business. They've even helped me fix a timer that they didn't install! I will use them for all electrical work from now on!

The team was on time and very professional. The projects went smoothly and the I was communicated with on the status and outcomes of the work being done. I have more work needed in the future and will use these guys again.

Cornerstone did a great job removing an old outdoor hanging fixture and replaced it with a new wall mounted one. They brought everything up to code at a reasonable cost. I will be doing business with them again.

The quality of service is excellent. The electricians are extremely knowledgeable, professional, and very clean. I have hired them for multiple projects and have been impressed with their work every time.

Drew is a great guy. Him and his partner installed a new electrical system for my pool. They took care of everything including all of the permits and coordinating the inspection process with the town. His prices are fair and he does what he says he's going to do, when he says he's going to do it. I would highly recommend him to anyone!

Josh and his crew are highly professional. The attention to detail and care for each project is outstanding. I highly recommend Cornerstone Electric

Responsive professional company. Vinny was efficient and completed project on time and at fair cost to me. When I need even larger project like a Generac or whole house surge protector, I will call here first.

Ed and his team at Cornerstone Electrical Services always go above and beyond to make their customers happy. We have Ed and his team do all our electrical work for our customers because we know they provide the best service around. Highly recommended!!

Worked very closely with Josh and team on a comprehensive residential electrical project that included an antique main house, various outbuildings and landscape lighting. Cornerstone handled all the work with attention to detail, knowledge, and great suggestions. We are very happy with the electrical upgrade and would highly recommend them for your next electrical project.

My wife and I have used Ed and his team to do a couple of simple electrical jobs for us and have always found them to be great to work with. Offering a professional and competitive service every time.

We would have not hesitation in using Cornerstone Electrical Services again.

We are very satisfied with Ed & CornerStone Electrical Services. They have done quite a bit of work at our house and each time we have had no complaints with Ed or his crews. Very professional, friendly, neat, always returns our calls and shows up at the time they said they would. Highly recommend Cornerstone Electric!

Cornerstone Electrical Services has been my go-to electrical contractor for the past several years. They are always professional, and their work is excellent. My most recent experience was with a bathroom renovation. They were flexible and worked with my General Contractor to get the job done. I highly recommend Cornerstone Electrical Services.

Joshua Martinez, Owner of Cornerstone Electrical Services, LLC is in a class of his own! I have been a customer of Cornerstone Electrical for over 5 years and there is no other company I would trust with my electrical needs.

The ethics, professionalism, and expertise of Cornerstone Electrical makes the company second to none. Joshua is beyond conscientious and takes the time to understand the needs of the customer, to ensure the best product and service. He never pressures, and instead educates customers so they will make the best decision for themselves.

Joshua is the type of guy who will arrive at your location to help with an emergency to ensure customer satisfaction. He did just that for me when my TV wasn’t working the day before extended family was set to arrive on Thanksgiving.

Joshua only hires exceptionally qualified electricians who possess the same character traits as himself. As a retired Army Colonel and present C-Suite Executive, attention to detail, reliability, and a “make it happen“ persona, resonates well with me. I emphatically recommend Joshua Martinez and Cornerstone Electrical Services LLC, for all your commercial and residential electrical needs. No job is too small or too big.

Staff was prompt, efficient and professional. They explained things that needed explanation and any follow-up questions. I would certainly recommend.

Ed was referred to me by a neighbor . I moved into a condo which needed alot if electrical work . His crew did an excellent job . They were on time , courteous, and very knowledgeable. I would recommend this company . They took their time installing my beautiful new chandelier. And bedroom ceiling fan along with other jobs . Thank you Ed .

I recently had Cornerstone Electric over to handle some electrical work at my home. While we did have a bit of a rough start initially, everything ended up working out just fine. The work was done professionally, and I want to give a special shout-out to Anthony, the technician, who was knowledgeable and courteous throughout. Later on, Vinny came back to hook up our spa, and he was just as much of a gentleman and a true professional. In the end, I’d definitely recommend Cornerstone Electric. They got everything done well, and we’re happy with the results!

Tommy hurried to help me when I had multiple smoke detectors chirping even with new batteries. He carefully reviewed the situation and noted that this problem happens with old detectors. I confirmed that they were 10 years old. He gave the practical advice to replace them. Fortunately, he selected replacement detectors with lithium batteries. They will never need battery replacements! All of them were replaced efficiently and quickly. I’m thankful Cornerstone sent Tommy to do the job!
