    2 bedroom 1 bath addition
    $220,000

    We did a addition to our house. Overall I was happy with the finished project. It was challenging at time not as smooth as I had hoped for. That might partly be due to my expectations. If was going to have more work of that nature done I would have them bid another job for me

    Earthquake Bolt and Brace of foundation
    $8,500

    We highly recommend Cerletti & Kennedy for the Earthquake Bolt & Brace (EBB) work done on our home in Pittsburg, California, in September 2024. If our experience is any indication of the quality of their work, we can also highly recommend them for any other construction work you may need.

    Once our EBB application was approved, I endeavored to get a good range of quotes: I received seven quotes from different companies, even though only three were required. There was one company that stood out from the rest, providing comprehensive information on the materials to be used as well as the installation process. Matt Kennedy also spent a fair amount of time on the phone with me, explaining exactly what the work entailed. Happily, their quote came in under the amount allotted by EBB.

    What really cinched the deal for me was that I didn’t have to come up with any money up front for the permits or inspections. Cerletti & Kennedy handled everything for us. To top that, the two-man crew they sent out were two of the nicest workers I’ve encountered. They were efficient, neat, and cleaned up at the end of each work day, accomplishing the whole job in less than a week. No stress, no problems; just peace of mind. Simply put, a job well-executed. Thank you, Cerletti & Kennedy!

    Rebuild double stacked deck.
    $32,500

    Outstanding quality and service from C&K. The quote process was easy and friendly. The plans for the deck rebuild were thorough and they completely handled getting the permits and approvals from the city. Their workers were pleasant and respectful and highly skilled.

    Everyone in the neighborhood has commented at how beautiful the deck now is. I cannot wait to enjoy my new deck!

    I highly recommend Cerletti & Kennedy, and would definitely use them again for any work you need to be sure it will done correctly, with safety and beauty in mind.

    Bathroom remodeling, drywall, painting, etc.
    $32,500

    We lately had a master bathroom remodeling project, plus bedrooms’ popcorn ceiling removal, drywall work, painting and etc.. Ruben who worked on our project deserves a special Thank-You for his great workmanship and mostly with his attitude of I-do-it-with-my-heart (that was his own words).

    And another noteworthy remark, as what Matt once told me what he said to his crew member, “Do it as what you would do for your own house.”

    Though there were some issues, such as, scheduling and delay (caused by wrong order or material supplier’s inventory), the job was well done! My wife and I are very happy with the final result! This has been the third project in our house done by Cerletti and Kennedy since 2016. That speaks volumes.

    Kitchen remodel and entire home flooring installation

    Definitely would highly recommend Cerletti & Kennedy! We contacted them for a full kitchen remodel and entire home flooring installation. First met with Matt a conscientious and detailed design engineer who listened to my ideas, did the technical drawings and measurements including brainstorming how the design would work. Matt created a wonderful design of the kitchen— cabinets, countertops, lighting, backsplash, down to the finishes, for example cabinet and drawer pulls and handles. The kitchen, including all the appliances, is beautiful!

    Robert gave us a bid on the project and was the contractor in charge of the crews and coordinated trades from demo to installation of plumbing, electrical, dry wall, cabinets, lighting, etc. Although there was a slight delay of a week or two the job was completed and professional done. The crews were polite, hard working and respectful of your property. The photos speak for themselves!

    Thank you Cerletti & Kennedy

    Best,
    Julie and John Torell

    design apartments in mixed-use space
    $12,000

    Matt Kennedy has been amazing. I had originally hired another designer to design a mixed-use space including three seconds story apartments in a commercial property which went very south. Matt not only completed the design of the three units but was able to negotiate use of space with the City. He has intimate knowledge of the City Codes and has a good rapport with the City Planning and Building departments. He is also very helpful and available to answer questions and provide information. I am very grateful Matt was recommended to me and I'm so glad I've gotten to work with him.

    Kitchen Remodel

    Matt and Robert were a dream come true - we had a pipe burst right when COVID hit last February and couldn't get any contractors to even come give us an estimate. The ones that did come bid very high and refused to deal with our insurance company. Matt and Robert have so much experience and made the process so easy. Their crew was fantastic, on time, respectful and highly professional. We were able to remodel our family room in addition to our kitchen and they are both beautiful! We will for sure use them for any future home improvement needs!

    Foundation Work
    $1,500

    In 2019, Matt Kennedy and his team completed an inspection of our home’s foundation bolt and bracketing and added additional bolting to bring our home up to current earthquake codes. The inspection and work was done professionally, on time, cleanly, and in a singe day. Their work led to a 20% reduction of in our insurance bill. That represented a speedy payout of this project in less than two years and the piece of mind that our home was in good shape for the next big one that will be coming.

    Bathroom remodeling
    $40,000

    The second time we hired Cerletti and Kennedy since 2016. The first time was addition, and this time bathrooms remodeling. We are very happy with the new bathrooms! Whoever visited our home recently have been saying, “Wow!”
    Job well done!!!

  • October 22, 2016

    I asked Matt and Robert to build a new kitchen and turn my old kitchen into a memorial room for my son. They have exceeded my expectations and given me the kitchen of my dreams. Robert is a visionary and has really great ideas when it comes to adding an addition. He gave me several options which I really appreciated and I'm very satisfied with what they've done for me. I love my new kitchen and the central heat and air makes my home very comfortable in both summer and winter.
