The county retained Bowman & Williams (B&W) to do preliminary damage evaluations in the disaster area. We were required to obtain 3 quotes to qualify for state and federal disaster relief. B&W offered the required survey and construction design services and always came in with a competitive price. As work actually got underway an alphabet soup of regulatory agencies, FEMA, CA OES, WRCB, F&W, made various demands that impacted the design and B&W always responded quickly to keep the projects on schedule. With all the regulatory hurdles, permits, construction bids and county construction requirements it took until FY 2024-2025 to complete the last project and Bowman & Williams stuck with us thru the last bit of paving and the last guardrail.

    Knowledgeable team, but very poor communication experience…read more The response I received was dismissive, overly aggressive, and unprofessional. Instead of explaining their approach constructively, they criticized other bids and ended the conversation abruptly. I'd recommend getting multiple opinions and relying on an independent structural engineer rather than taking any one contractor's claims at face value.

    Avalon Structural is a truly professional organization across the board - front office, inspectors,…read moreengineers, and on-site repair staff. If you have a foundation crack, save yourself the time and trouble and call Avalon Structural first. I got multiple estimates for my fairly extensive ~23' horizontal crack. I found there are three types of companies. The first type will do the minimum to chip out the rusted rebar, throw some fresh rebar in there, patch it up with a "band-aid", and charge you handsomely for a quick in-and-out job. The second will glance at your foundation and immediately tell you it has to be replaced, for an even more handsome price, of course. And then there is Avalon Structural. They will perform a comprehensive and highly structurally sound repair, removing all compromised material, charge a fair price, and stand behind their work with a strong warranty. If you visit their website, read the articles, and watch the videos explaining the right and wrong ways to perform foundation repairs, you will be well-equipped to choose the right company for your foundation job. Or, you can save the time and just call them. We couldn't be happier with our repair. The foundation looks great and feathers in perfectly with the undamaged foundation sections. The repair team was amazing and extremely respectful of our property. The city inspector signed off with zero issues, which speaks volumes about the quality of their work. A big thank you to Roger, MJ, and the entire Avalon Structural team!

    Joe is a life saver. We have called him in during two emergencies, and he has come through for us…read moreboth times. The first was to rescue us from a half-finished bathroom remodel where the original contractor abandoned the project half way through. We could find no other contractor that would touch the project, because you never know the quality of the work already done, and you are kind of assuming responsibility for it. Joe stepped in, fixed some things the previous contractor had screwed up, and finished the bathroom just in time for us to be able to celebrate Thanksgiving with the family visiting. The second time was similar. We had a water line break and it damaged the entire bathroom in the master bedroom. We were displaced from our bedroom and the house was hazardous. Joe was already booked with other projects, but was able to rearrange some of his staff and was able to start fixing the house that very day. Three weeks later, we had a beautiful bathroom. We hadn't anticipated doing another bathroom remodel, and certainly hadn't budgeted for it. Joe's price was very fair, considering the emergency nature of the project and the fact that he had to have people on overtime to help complete the job. I highly recommend JM Construction. They are life savers.

    The city works dept managed to flood our downstairs with sewage water, and Joe Martines and his…read moreteam expertly handled every aspect of the repairs and clean-up. They worked long hours to put us out of our misery and leave our downstairs bedrooms and bathrooms looking (and smelling) like new . When it came time to fix our leaking roof terrace, I of course called Joe, and he did a great job. His prices are reasonable, and I intend to use him for all our future construction work. Hopefully it won't involve another sewage flood.

    My partner and I hired HC Design and Construction originally for engineering services. When we…read morefound out that they were able to take on more projects after completion of our original we felt relieved knowing we wouldn't have to continue shopping around for an additional service provider. Humza and his team do a great job.

He doesn't appear to be phased by not doing what he says or fulfilling anything pertinent to the relatively small part he may have had for this project. The underlying theme of his inconsistent communications and mixed messaging, is akin to throwing out a bunch of fishing lines hoping to snag something with one or more them. So he arrives for an introductory visit to see the job. Then he repeatedly grouses at end of brief visit and for weeks later because he claims to usually charge for an intro appointment. But that's not what we agreed to from the onset. All he seems interested in, way late and after burning this bridge for weeks and not responding timely or at all on topic, is to recoup money for an intro appointment he agreed was no charge, then send vacuous emails off topic and complain that he's not been paid for them either. He punctuates that carnival like behavior by fixating on soliciting a large retainer ahead of some unknown level of service to follow on an hourly basis. Such an unprofessional, predatory manner of stringing along well intentioned potential property owner and some contractors. Not a good or trustworthy or professional look or experience by any measure. If I was to ever revisit this with him, which is highly unlikely, I'd be sure to charge him a retainer up front.
