I hired them more than three years ago and I paid for the full scope of work they recommended. My bedroom and closet have continued to leak every time it rains. I have given GMBC numerous attempts to fix the leak over the past 3 years, but the leaking persists. Two other companies have determined that GMBC did not do the work required to fix the leak and used improper materials. Moishe is the manager and refuses to resolve the issue. Horrible work. Horrible experience. Do Not Use them unless you just want to waste money!

A Nightmare Experience with GMBC: Poor Craftsmanship and Unreliable Service…read more Hiring GMBC for our renovation project was a terrible decision. The experience was a complete nightmare, with their shoddy craftsmanship and unreliable service leaving me deeply dissatisfied. We worked with Moshe and had numerous conversations about the quality of work but he did not care. The project initially estimated to take three months, dragged on for over a year. Here are the major issues I encountered: 1. Poor Quality Craftsmanship: The work done by GMBC was riddled with errors and executed in a sloppy manner. The foreman was rarely present, and when he was, he consistently overpromised and underdelivered. Their lack of skill and attention to detail was evident in poor flooring install, uneven paint jobs, and a complete disregard for precision. A few examples of their subpar workmanship, but by no means comprehensive: -A small deck featuring cracked spindles/railing. The wood was so discolored that we paid them more just to try to cover it up, with the end result looking even worse. -We paid them thousands to level our floor and install flooring, but the end result was warped and bouncy. After we pointed it out, they suggested drilling holes all over our new floors and trying to glue everything down. -A sliding shower door installation that was unlevel and featured a half inch gap all the way around. It was so bad that we couldn't even shower in the room without the bathroom filling with water. There were several issues such as drill marks and permanent marker drawn all over from where they made errors trying to install the first time. -We paid them to install soundproofing on a shared wall with our neighbor. Moshe himself noticed there was absolutely no change when he came over to check on the things, and could hear our neighbor's music as if it was in the same room. There was no suggestion on how to resolve or make the situation right on their end. We ended up paying thousands with absolutely no result. 2. Unreliable and Unprofessional Crew: The crew assigned to my project displayed consistent lateness and unprofessional behavior. The foreman was rarely around and the crew was often on break, resulting in wasted time. Their lack of professionalism extended to a disregard for my property and basic safety protocols. They installed a stacked washer and dryer without the provided stacking kit and when we were told it was ready for use, the washer ended up walking itself out of the laundry room and into a wall, further damaging the unit as well as the brand new floors we had installed. GMBC's reluctance to take responsibility for their mistakes and their laborers' inability to perform as professionals further added to my frustration. GMBC did eventually reimburse me for the dryer. 3. Missed Deadlines and Extended Delays: Despite GMBC's promises of efficiency, the project suffered from poor planning and an inability to adhere to timelines. The extensions of the project disrupted my daily routine and caused unnecessary delays. Inspections were missed multiple times, leading to wasted time and frustrated inspectors. I brought this up to Moshe and he told me the guy was in his car for one of the inspections and didn't see the inspector ring my doorbell. How is that acceptable? 4. Dishonest Practices: GMBC exhibited a lack of honesty and integrity throughout the project. They lied about placing an order for a specific closet door, stating that the one we had requested was out of stock but when we called the store ourselves, they had 5. GMBC just didn't want to admit that they had made a mistake. We had a similar scenario with the original shower door that they had installed where a subcontractor they sent to replace the original door stated that they had installed it incorrectly. Their poor record-keeping was evident when they failed to provide complete receipts for reimbursements. Additionally, they attempted to charge me for something I had already paid for. 5. Lack of Design Sense: They failed to deliver work of which they could be proud and omitted showcasing it on their website or social media. The solutions provided for an eyesore firewall and poorly done concrete work in the driveway were unsatisfactory. Their lack of effort to find acceptable options and costs left me disappointed and seeking help from other contractors. On top of everything, I was pregnant when the project started and then had a newborn when they were still working at the house. It was an absolute nightmare and so stressful. Moshe's attempts to fix things later were too late, and the inconvenience wasn't worth it. Eli got involved towards the end and seemed reasonable when it came to deducting items on the poor work that was done. My husband ended up fixing a number of things after they completed the job. Overall, my experience with GMBC was a disaster. Their lack of professionalism and poor workmanship make them a company to avoid.

I found Optivest Build through Yelp's project system and one thing that stood out right away was…read moreMoe, the owner, and his responsiveness. Out of the companies that responded through Yelp, he came across as one of the most professional and serious about understanding the project rather than simply giving a quick estimate. He replied quickly to my questions through Yelp and was able to come out in a very reasonable timeframe to evaluate the work and discuss ideas in person. We hired Moe and the Optivest Build team for a decorative pergola/faux balcony repair and replacement project involving redwood, exterior trim work, stucco work, door jamb and casing repairs, sealing, and painting. The contract process was straightforward and I appreciated the flexibility and payment structure based on project milestones rather than everything being front-loaded. After Moe's initial site visit and evaluation, it became clear that a more comprehensive rebuild approach for most of the structure made more sense than piecemeal repairs. Moe explained the long-term benefit of rebuilding the deteriorated portions together rather than replacing isolated components now and potentially dealing with additional mobilization and repair costs again a few years later. I appreciated that he was not simply replacing wood, but also improving areas where the original design appeared to contribute to moisture issues. As the project progressed and portions were opened up, some additional weather and age-related deterioration was uncovered, which led to a few adjustments and additional repair steps along the way. Moe worked with me through options for addressing things as they were discovered and helped walk me through the process and next steps, which reduced some of the stress and uncertainty that can come with larger exterior repair projects. What stood out to me was that Moe stayed involved throughout the project, communicated with me consistently, personally came by to check on things, and had his project manager and crew return when touch-up or punch-list items needed attention. Even as the scope evolved, Moe stayed engaged throughout the project and continued working through follow-up, touch-up, and close-out items professionally. The crew was always polite and respectful of our property, worked hard throughout the project, and the project was fully cleaned up and closed out professionally at the end. No construction project is completely stress-free, but I appreciated that concerns were addressed and that the team worked to make things right when needed. In the end, the pergola turned out looking great, as did the additional trim, stucco, and repair work completed throughout the project. We are happy with the final result and would feel comfortable recommending Moe and Optivest Build to others looking for a responsive and professional contractor. Grateful to Moe and his crew for their job well done.

They can cover any type of work from landscaping, structural framing, electrical and plumbing, up to fine finish work and adjustment.

The cost estimate and proposal for the work performed and what is planned for the ADU seems efficient and fair.

I am writing to highly recommend Stephen Dickinson and the team at Tri-Valley Construction…read more From start to finish, Stephen proved to be an incredibly wonderful and helpful contractor to work with. What sets him apart is his deep expert knowledge; he doesn't just execute a task--he takes the time to explain the 'why' behind his process, ensuring the job is done right the first time. His professionalism, attention to detail, and willingness to go above and beyond made a significant difference in our project. If you are looking for a contractor in the Tri-Valley area who is reliable, skilled, and genuinely invested in his clients' satisfaction, look no further than Stephen.

This involved removing sheetrock, cutting pipes, installing new valves, then replacing the sheetrock, applying plaster and texture, and finally painting. This was way above my pay grade, so I reached out to Steve. Within minutes, he got back to me. He asked for photos and provided an estimate with a range, depending on the complexity of what they found. Steve sent his crew over just a few hours later to begin the project. Victor and Edgar arrived, and within minutes, the Sawzall was going to town on our wall. I'll admit, I had my reservations, but it quickly became clear that these guys knew what they were doing. Each phase required a return visit to allow the individual coats of plaster to dry, etc. Our water was only turned off for about an hour or so during the entire project, and the finished product was very good. We're now considering TVC for other projects. I would not hesitate to recommend them!

We worked with Jacob's company, S&L Remodeling in Walnut Creek, and from the very beginning his…read moreentire team made us feel like our project truly mattered. Even though this wasn't the largest remodel for their company, they treated us as if it were a million‑dollar renovation -- with care, respect, and exceptional attention to detail. Jacob was an outstanding owner to work with. He approved everything quickly, stayed flexible, and worked with us on a payment schedule that made the process smooth and stress‑free. His communication was clear, and he made sure we always felt supported throughout the remodel. From the project manager to the foreman, to the crew and subcontractors, everyone showed up ready to deliver. Jacob's team moved fast -- gutting the kitchen, updating the wiring, and completing an impressive amount of work within the first four days. The craftsmanship was excellent, and the workflow was organized and efficient. Jacob was involved with our supplier who handled all the materials, including our new cabinets and kitchen counters. They kept everything on schedule and made the selection process easy. There was no constant back‑and‑forth, no need for us to oversee every detail. The team stayed on top of the project from beginning to end, keeping the schedule tight and the quality consistently high. Even with the limited funds we had to work with, they transformed our old, dark kitchen into a bright, modern, beautifully updated space that is completely new. The results exceeded our expectations. We're truly grateful for the professionalism, consistency, and quality of work from S&L Remodeling. Jacob's leadership and his team's dedication made the entire experience exceptional. Highly recommend.

From the beginning, the team was professional, detail-oriented, and incredibly responsive. They remodeled the entire kitchen, transforming it with sleek quartz countertops, a new sink, faucet, backsplash, and freshly painted cabinets. The result was modern, clean, and exactly what today's buyers are looking for. They also renovated both bathrooms with neutral tones, contemporary tiles, updated fixtures, and glass shower enclosures--elevating the overall aesthetic and adding real value. The front and backyard landscaping, front door repair, junk removal, and AC repair were the finishing touches that really made the property shine during showings. The investment was absolutely worth it. Thanks to their thoughtful upgrades, I was able to sell the house quickly and at a great price. Highly recommend 4Sigma if you're prepping your home for sale--they know how to make a property market-ready in the best way possible!

Antone and his team at NS General Contractors exceeded my expectations. First, their proposal and…read moredescription of the course of works was clear and augmented by photographs and video. Easy to understand and appreciate. They expertly tackled a dry rot nightmare on the back of our house - a nightmare which we though had been remedied by another contractor years ago. Turns out that contractor made matter worse. Antone and crew were able to identify the sources of water intrusion - roof, gutter, a rotted window, wood siding, you name it. It took some time chasing down the dry rot, but the end result is that this side of the house looks as good as the time of original construction. The crew was punctual, neat and tidy, coordinated well with other trades, and they were fair in their pricing. All in all, a solid performance. I have referred NS Contractors to a work colleague, and will invites them back to address some fix-it items on the front of the house.

We recently completed a handful of projects with MDesign and couldn't be happier with the results…read more From initial design to the final touches, the entire process was a pleasure. And I hold a high bar! Mila was incredibly adept at bringing our vision to life -- she took my inspiration photos, style descriptions, and feedback on visual renders, and turned them into show-stopping, custom pieces. She was exceptionally patient through numerous design iterations, never making us feel rushed and genuinely wanting us to love the plan before construction began. Her 3D renders were invaluable, as I really needed that visual clarity to make decisions. She is the ultimate design partner-in-crime! The construction crew was equally impressive. They were reliable, patient, courteous, attentive to detail, and highly skilled. We also really appreciated Ben & Mila's client advocacy. Whenever issues arose or price negotiations were needed, they stepped in and advocated for us, demonstrating ownership of the project from start to finish. It gave us immense peace of mind knowing they had our backs. We highly recommend MDesign!

Before I sing…read moretheir very impressive praises, you might want to take a peek at our photos that we took on our own; without using a professional photographer. Upon interviewing Mila and Ben, MDesign owners, without hesitation we went into contract. They offer comprehensive services under one umbrella. We didn't have to look for a separate contractor, interior designer, or painters, etc. We didn't have the time or energy to do all that work. There are other companies that require so much work on your part that we dismissed them quickly. The big question is always how good are the laborers that are actually going to do the work. Well, they are amazing and extremely hard working, very talented, and professional. They never hesitated to walk the extra mile for us, when we asked. I just can't highly recommend MDesign enough. Do yourself a favor and save yourself time in not hesitating to hire MDesign. BTW, they're also very easy to work with and make you their top priority. Enjoy our photos!
