Gandaras recently redid our electric and then our kitchen in a large remodel. From start to finish the service by Carlos junior and senior was professional and the end results were phenomenal.

We had nob and tube wiring that they removed and then proceeded to upgrade the entire home adding new labels and 25 over head lights.

We wanted a luxury kitchen and they delivered all at great pricing.

This is a family business and I can't tell you how kind and nice this family is. These are people you'd want to have at a bbq! The father has 3 sons working with him all with their own unique skill sets and expertise.

I'm so happy with them and would highly recommend them for any large project. Here's a pic of their work on our kitchen

100% Awesome. Gandara's did circuit breakers, ran line, outlets, switches, recessed lighting and drywall for me. Everything looks sharp and works great. It's a family business and working with all the Gandaras has been a pleasure. I felt like they listened to me as a customer and took time to answer my questions in ways that I could understand. Carlos Jr created multiple estimates based on my changing plans quickly and with no problems. They always showed up on schedule. I think that they're a professionals who are also easy to talk and work with--something that I appreciate. I look forward to hiring them again for other projects.

We just finished having a kitchen remodeled by Carlos and his fantastic team!!! They removed a wall, a door, put in our new kitchen cabinets, and a new backsplash, and a new countertop! It came out better than we expected. Carlos knows his stuff and his whole entire team are nice people I feel they are like family. We wouldn't trust anyone else to do any work around our house. He's trustworthy, honest, and finishes the work right to the last detail. We are having some small jobs jobs done and he's our guy!!

I sent a request through yelp to get my self purchased Level2 EV charger installed at home. Carlos reached out and was able to come by my home quickly within my request for an estimate. Around this time the Bay area was having intense storms, and he was willing to work quickly with me since I was anxious to get my charger installed. Anyone who has a drip charger at home with an EV knows why!

I really appreciated his patience with my questions in lieu of circumstances that he and his company had to deal with during the storm. Once the permit was obtained, he offered to come out ASAP for the job. His team worked quickly, everything was clean looking and they were professional.

He even made sure to follow up with me to make sure my charger amperage was at the desired level, and made an in person follow up to be sure of it. I couldn't have asked for more.

I did not have a comparable quote from another company, but I feel like the cost for the job was reasonable. My garage didn't have the main breaker nearby, OR the outlet to support the charger. So more material than your average charger install I'm sure was needed. My city also had a lot to request for the permit, and certain criteria that I wasnt expecting, but they handled it no problem.

This was my first experience, and it was great. I hope to have another one like this with them in the future because I will be reaching out for future projects. Thanks!

We needed electrical work done in garage before drywall install and Gandara's Construction was able to do it in time. Their work quality is top notch and will likely have them back for more electrical work at our house in the future.

We decided to move with our son Carlos and add to his home a master bedroom with bathroom, a family room and an outside patio, together with a new driveway, and design it in a way that when remodeling was finished it looked as an original built home.

A very good friend of us, an international interior designer recommended us
Mr William Gandara of Gandara Construction Company, with whom she had worked before and was very pleased with his work. We took her word and called Mr. Gandara to set a meeting with him and explained what we wanted to do and our expectations. Explained who we were, being a Civil Engineer myself, having built both overseas and in South Florida as developer and contractor. We felt very comfortable with him and set a meeting. He arrived on time and brought over his architect, both very understanding, courteous and knowledgeable. Explained fully whom his structural engineer, electrician, plumber, roofer, supervisor and rest of team were.

We explained to his architect what we required and asked William to get back to us with a turnkey contract including a draft of the addition.
A week after he came back with a contract, a floor plan and a perspective of the new construction. We made some adjustments to the plans and his quote was very reasonable, so we accepted his pricing without asking for a discount. We were very fortuitus in working with William. He always answered our calls, was punctual on time, was on top of the job daily, met on time all inspectors, had excellent crews working for him, finished on time, which is not an easy thing to accomplish, worked very clean and Omelio, his foreman was more than helpful throughou.

We ended up becoming family friends with William and his lovely wife Janette, and for sure we will use him and his firm in other future construction projects. Without hesitation we endorse him to anybody that is looking for a construction firm, as knoledgeable, honest, punctual and hard worker.

Great crew of guys! The install of my transfer switch was quick, well-done and was one the best prices I found out of quite a few company's I had contacted. Highly recommended. I wouldn't hesitate to use Gandara again.

I cast a wide net looking for a team to help install an electric vehicle charger. I went back and forth with a few other companies but Gandara's was quick to respond, straight to the point with the pictures I provided and offered the best estimate. I was even able to schedule an installation appointment the following day. If you're looking for a team that gets things done fast and on time, hit Gandara's up!
