Andres came right away to fix my garage lights. He diagnosed the problem within about 15 minutes and carefully showed me why he thought that was the problem. Turned out that the old fixtures needed to be replaced. He was able to find and purchase new fixtures for me and came back right away to install them. He was polite and quick and got the job done.

Wilmar was great, he helped swapped our an EV charging outlet we were having issues with and the new one is working great! He also checked our circuit breaker to make sure everything was tight and in good order!

JD Lopez helped me convert a Burlingame garage into an ADU. It had been sub-divided w/o a permit before I purchased the property and so I was anxious about the process to get it into compliance. He oversaw his crew as they converted the garage into a living/kitchen. The crew was very respectful and kept things pretty clean, all things considered.
He worked collaboratively with my Architect (Alex Tzang, also a 5-star) to clarify as needed. There was an issue where the front facade had to be raised (after framing) to account for water sloping from the driveway. Although a bummer that it had already been built out, he/his team re-did the work and the City was reasonable on the solution given that the garage header and roof were fixed. Whew!
Overall, it took longer than I had hoped for what I thought was a small job but construction projects in 2021 were hectic.
JD stayed true to his estimate. Of course there were additional costs as I we got into construction and I realized that some things were better to be done while the patient was on the table, so to speak, but I chose to add the costs and there were no surprises.
Looking back (this review is overdue), I would highly recommend JD Lopez. He's a very calming presence during a hectic time for people and I would definitely hire him again...if he is available!

We hired him to install a 600+ sq feet deck and railings... awesome job and very reliable and he does what he says.

I wanted to revamp my kitchen and guest bathroom I found JD through yelp gave him a call in which he responded to promptly. We spoke a bit on the phone I explained to him what my visions were all while taking pics and sending it to him as we were talking. He gave me some suggestions and talked about his past jobs, I liked that he was enthusiastic about this project and had a lot of knowledge with the style I wanted. He came over the next day to see everything in person. We talked a bit about pricing until we found a happy medium for the both of us and from there JD took over. He did everything in a flash! Sometimes with contractors they end up being very slow and trying to juggle multiple clients at the same time, I didn't feel this with JD. I recommend calling JD and just talking to him if you are looking for a contractor.
