Thank You, Eli, Armando, and crew, for completing the construction and remodeling of the garage space for a game room, bathroom with toilet, shower and sink, and a wet bar. Your work is outstanding and your contract services were both fair and affordable for me as a first-time homeowner. This was not an easy project and required additional unexpected improvements as required by the Daly City Construction Permit Codes. My house belonged to my Grandma and there were many required changes before the construction was completed: pipe and sewer improvements, earthquake-seismic foundation enforcements, structural improvements, reconfiguring the garage door for code compliance, and other issues. This project started in 2018 and has just completed final inspection from the City of Daly City, I owe a debt of gratitude to GMBC for their patience and professionalism. Throughout this process, GMBC would communicate and discuss additional costs before he did anything. Eli gave me the assurance that everything will be worked out and in compliance with the City of Daly City. He was right and I am so grateful. I would hire GMBC Construction in a heartbeat. Thank you, Eli, Armando, and crew.

Details: Change the form or function of a portion of a room or structure • In-law unit or guest house • Bungalow • No existing plans - need design suggestions • No, the project is not covered by an insurance claim • Within the next 3 months

We hired GMBC to remodel our kitchen, 2 bathrooms and a master closet. We interviewed 6 other contractors before we chose GMBC. What sold us was how easy it was to talk to Eli. He was always open to our ideas and also offered his input without being too pushy. After we chose GMBC, Eli drafted a statement of work that broke down the job according to room. After a couple of adjustments, we were ready to begin. Although the end result was fantastic, getting there was a bit tough at times. Like most renovations, we experienced a number of delays and setbacks. We were told the job would take 6-8 weeks but it actually took 4 months. A lot of the directions or requests we were giving to Eli weren't being communicated to the crews, so things wouldn't be done correctly and had to be redone. Sometimes they would need items that weren't communicated to us until we checked in asking why something wasn't done as scheduled. Inspections took a few rounds that dragged on for over a month. Some of the delays may have been our fault - we probably could've made things easier by hiring an architect to draw up detailed plans of everything; locations of outlets, lights, switches, fixtures, etc. But for the most part, the biggest issue seems to be a lack of communication/project management. GMBC uses different teams of people to do specific jobs and sometimes we felt they weren't on the same page. Fortunately, we happened to be living downstairs during the remodeling, which allowed us to survey the work at the end of each day and catch certain things before they went too far in the wrong direction. Not sure how much more difficult it would've been if we hadn't been there. Also, we had mentioned to Eli this was our first remodel so advice and communication was pretty key for us since we had no idea what was expected. That said, Eli and his crew were always courteous, positive, and obliged to make corrections whenever requested; a huge plus. The foreman, Armando, was great. When he was onsite, things always went smoothly. Their tiler was exceptional as well. He went above and beyond with some complicated tiles, and did an incredible job. We get so many compliments on our tile work. All in all, we couldn't be happier with the results. The quality of work is great and our home looks amazing. Everybody came together to make our vision a reality.

Details: Multiple room remodel • Kitchen • Bedroom • Bathroom • Split-level • No existing plans, but have a good idea of what I want • No, the project is not covered by an insurance claim • Within the next 3 months

We got our 3 bathrooms remodeled and we extended our kitchen and Eli was great. He came with the architect right away to do the layout of our new kitchen and they submitted them to the city and got permits within a week from when we signed. Less then 3 months later, we have 3 new bathrooms and a huge new kitchen and it is perfection. We are so happy and thankful!

Right in time for New Years! I have a whole new kitchen, dining and living room, 2 remodeled bathrooms and a whole new backyard with a new deck, huge hot tub, and pergola. Eli and his team worked day after day and extremely hard to complete this project in the time I wanted. They did everything professionally and made my dreams come true. They took care of everything. I did not need to do anything at all, which is perfect because I wanted a company that would take care of everything. From the day I signed the contract, I knew what was going to happen weekly and always felt comfortable asking Eli or calling up the office to have any questions answered. I was never turned down or made to feel like I was being problematic (which I am sure I was!) but everyone there continued to impress me day by day with how thoughtful, kind, and clean they were. I really believe in life you get what you pay for, and with Eli and GMBC Construction, I paid and got much more then I actually paid for. The experience, and now the finished product is just fantastic. Thank you, thank you to everyone at GMBC Construction!

  • What should the customer know about your pricing (e.g., discounts, fees)?

    Pricing varies based on size of the project and what materials are wanted. We sit with you and go through everything and make sure that everyone is happy and satisfied with the pricing.

  • What is your typical process for working with a new customer?

    We come out to a potential client's home to give a completely free estimate and get to know each other while we are talking about the work and price. Once we get to know each other and establish that we will work well together, we then go on to signing a contract that makes both us and the customer equally happy. Then the job gets started and finished nice and quickly, all the while making sure the customer is satisfied as the job is being completed!

  • What education and/or training do you have that relates to your work?

    I have been working in this field for over 10 years in many different parts of the country and have now settled in the Bay Area with my own company and cannot think of anything better to be doing then construction! It is a wonderful feeling when a job is completed and the customer is extremely satisfied with what has just been done to their home.
