    The Great (+2 stars) ==========…read more * The structural work: Our home is on a great, new, solid foundation (with shear walls), so we feel as safe as we can be in our home for an earthquake! * Our basement is also now more usable. * Drainage: There is now drainage around the foundation and under the basement slab, so we are no longer worried about our basement flooding! * The working crew were very friendly and considerate. The Bad (-1 star): ========== * The electrical subcontractor was quite bad. The electricians didn't install the dryer outlet properly (one conductor came loose before I first used it), most outlets they installed are loose (they give when pushing in a plug), and they installed a used, old (not LED compatible) dimmer for the LED lights they installed. Also, the owner yelled at his team a lot. * The plumbing subcontractor was bad, too. They misdrilled several holes, damaging the interior of the home. They didn't seal around exterior penetrations into the house. They didn't put a cover over the branch of a wye that was no longer needed. They wouldn't do anything about the loss of hot water pressure in a bathroom faucet that occurred after they moved some plumbing around (I ended up having to disconnect and disassemble the hot water valve myself and I found a piece of silicone clogged in there). They over-glued the drain of the laundry supply box making it nearly impossible to remove the cap, and they lost the o-rings on my faucet aerator. The Ugly (-2 stars): ========== * They overlooked details in the plans about where walls and doors should go, and denied responsibility since they weren't in the structural engineer's plans, which they opted to not have updated with the revisions I told them about. This lead to a sewer pipe being installed in an inconvenient location (it went through the foundation, so it can't be moved), a structural wall that was almost built in the wrong place (I caught it while they were digging the footing), and a room that was built with no doorway (they had to cut some framing to make the opening). * The pricing/scope was negligent at best, but I'd put it closer to misleading or deceptive. During the initial visits, they talked about all the things they would do (including putting up framing, drywall, and insulation), and then sent over an estimate that I accepted. I didn't realize until halfway through the project that the estimate didn't include many of the things they talked about (including the framing, drywall, and insulation); those apparently would be part of "Phase 2," not included in the price of the first estimate. I had chosen E&F over another estimate that was less expensive even though it did explicitly contain the "additional" scope. I was also surprised that the electrical and plumbing (most of which was necessary to get them out of the way for the structural work) was billed separately; i.e., an unexpected additional expense. * They chose to rebuild a segment of stairs (rather than just adding two steps at the bottom, per the plans), which ended up having insufficient clearance with an overhang halfway down. They tried to convince me there was no new problem because they built them the same as before (but the run of the new stairs was one inch longer, causing the 4th step down to be 4 inches closer to the overhang) and resisted remedying the issue. They just ended up taking a sawzall to trim the overhang -- a joist -- which I just have to hope doesn't compromise any structural integrity! Further, they didn't even finish the stairs (sand and seal); "Test your staining skills," they said. * They ghosted before Phase 2. As the structural work was reaching completion, we were going back and forth on scope for Phase 2. However, when the structural work was actually completed, they just stopped communicating, left dirt and demo debris they left on our driveway for a month, then disappeared. There were lots of things they removed to get out of the way (like several segments of fence) but didn't put back. I could easily add 3x more issues and details, but this review is already too long.

    We used E&F for a foundation replacement as well as seismic retrofit, including brace and bolt…read more They finished on time and under-budget, with good communication from both the owner and site foreman. I'm definitely planning to have them quote the next phase of our remodel!

My previous contractor had disappeared after demo (no calls, no texts for over a month, left their tools behind). Dan put together a detailed estimate and took the time to explain and talk through different options for the things that needed to be done. Throughout the project, he was prompt, communicative, and fair. Sterling and Phil came in and tackled all the quirks of a 100 year old house with experience and humor. When there were additional challenges (previous homeowner had screwed sheetrock over plaster in some places so the walls and ceiling were uneven, counters were not square or level, filled mismatched molding joints with putty) - they took the time to fix the old work and redo it correctly. They worked efficiently, paid attention to detail, and everything turned out beautifully. All three were professional, kind, and respectful throughout. I will definitely call on them in the future.

    Dan's price is reasonable and he itemized everything so its easier to track and adjust if needed…read more There is clear communication during the project regarding changes and extra charges, also his team did a good work remodel my basement. Workers come on time and work hard to finish the project, also they pay attention to most of the details. Several things that made me took off 1 star: 1. The window Dan asked me to purchase is different style than all my other windows and not sure why it took the team to install 1 window per day! 2. There are 2 times that I tried to provide concern or feedback on the project and Dan yelled at me in a disrespectful manner, basically he told me to step out of his way and he had the right to do whatever he want because he runs the project. This made me pretty unhappy and felt disrespected as a homeowner. His office manager is much nicer to talk to and maybe she communicated with Dan and it did not happen again. I would give 3.5 stars if Yelp allows, the overall experience is good except for some frustrating moments.

    We hired Prime Design for a home remodel project, but unfortunately the experience has been very…read moredisappointing. There have been multiple unresolved issues with the quality of work and follow-through. One example is an LED light that continues to flicker. It has been more than six months, with many calls and text messages, but the issue still has not been fixed. Another example is damage to our garage cabinet, where a hole was created during the work. We are still waiting for this to be repaired as well. Overall, the lack of timely resolution and poor communication after the project has been extremely frustrating.

    We contracted Prime Design & Build to remodel two bathrooms, a laundry room, a staircase, and to…read moreinstall hardwood flooring. Overall, the project went well, and we're happy with the final results. Bryan, our foreman, was a strong asset to the project. Even though he was managing multiple jobs at the same time, his responsiveness and willingness to go out of his way to address our concerns made a big difference. Because we were home throughout the process, we were able to catch issues early and communicate them directly to Bryan, who consistently followed through to resolve them. What Went Well: * The tile and flooring subcontractors were excellent - their craftsmanship and attention to detail truly stood out. * Bryan, our foreman, was responsive to texts and phone calls, listened to our concerns, and made sure they were addressed. He even designed a bi-fold closet door for us, and helped pick up all the material to build it. * Bryan also took the initiative to handle several unfinished items himself, which we really appreciated. * The post-build cleaners were top-notch and left the space in pristine condition. * Throughout the project, everyone we interacted with was professional, courteous, and conscientious. There were no conflicts or issues, which made the experience comfortable for us. Areas for Improvement: * The timeline was a pain point. While we were originally told the project would take 6-8 weeks, it ended up stretching to 12 weeks. * The design process fell short of expectations. Because Prime's in-house designers weren't available, our design work was outsourced. We only received a full design package for the master bathroom. As a result, we ended up creating our own renderings for the other rooms to help communicate our vision to the team. That said, we were very happy with the design and material selections for the master bathroom they did complete. We just wish the same level of attention and design support had been provided for the rest of the project. * At times, resource availability was limited, likely due to workers being assigned to multiple jobs. This led to workflow inefficiencies and delays. Toward the end of our renovation, our foreman Bryan had to personally step in to complete several tasks, such as installing faucets, shelving, and baseboards. He managed to get it done in between site visits and meetings, which we appreciated, but it also highlighted a lack of available crew to close out the project. Despite these few challenges, the quality of the work met our expectations. We appreciated the team's effort and the final outcome.

    We are very happy we used Tinka Construction to remodel our small bathroom and update our kitchen…read more George and his crew are super friendly, clean, and creative at solving transitions between spaces. His team is resourceful and they did not generate excessive work to add cost. For our kitchen / laundry facelift, we updated the flooring, backsplash, lighting, and reconfigured our laundry area. George's crew helped to side vent the dryer which the big box store was unable to do. George gave valuable input on our bathroom design to optimize the small space. He had suggestions for an in-wall toilet, a corner sink, window ledge niche, and talked us out of a doorless shower (thank you!). He knows small spaces very well and was able to place the fixtures in their best locations. George would give us a heads up on our requests that were going to cost more than ~1k. He had some subcontractors come in to help with varying degrees of quality and cleanliness. We are glad he managed the plumbing contractor who had to come back 3 times. His paint jobs varied quite a bit in consistency depending on who was painting. The best part of working with George was that we were expecting our first child, and he worked very hard to complete the project before her due date. To our surprise and delight he totally finished it before she arrived!

    George helped us with a complete remodel for our home in Berkeley. He and his crew (Oni, Enrique,…read moreMarvin, Wuillian) are extremely smart, honest, professional and creative. His pricing is also reasonable and transparent. We started with an awkward layout (even no room for fridge in the kitchen!) and ended with a tastefully transformed home: open, modern and feels much more spacious than before. George is patient, transparent, detail oriented (with a special eye for safety!) and always a clever problem solver on behalf of his clients. What he did for our project was too much to list, but I'm attaching a few photos where the end results can speak for itself! Contractors like George is hard to come by and highly sought after in the current environment, we would recommend him to any one who values craftsmanship and quality!

I know hiring a contractor is scary. There's a lot involved and they'll be in your house for an indeterminate amount of time which makes it really important to hire someone you can trust. Tom came out to provide an estimate for our project. He was the only one of the contractors I called that really investigated the existing condtions and repair based on what he could see and his own knowledge. He spent over an hour at the initial call making sure he didn't miss anything and talked through the potential issues and repair. This was his time spent not knowing whether or not we'd hire him. He was also the only contractor to tell me he would only do the work with a permit. Whether or not you think one is needed, just knowing that he wasn't afraid of the permitting or inspection process was a big plus to me. Always ask about permits during the interview process. He then went to his car, drafted an estimate and came back to talk to me about it. I was really impressed at this point. There wasn't any pressure from him to sign on and he encouraged me to ask questions. The estimate was well defined and a bit higher than another bid, but from what I saw I thought it would be worth it. After we signed on, he gave a rough schedule and starting time and said they stay on the job until it's done. We had a list of items to buy and he helped us out there too. He was in constant communications and always responded, even on weekends. Before the work begins, it is pretty easy to promise things to the client while telling your crew something else. When the work actually started, Jesus was our foreman and true to their word, he stayed on the project until completed. They were extremely respectful of our home, carefully protected things and kept the work area clean. During demolition, they found some unforseen things, but took care of it without issue. There were times when they could've easily walked through our house to talk to us, but instead opted to ring the door bell to respect our space. The construction went smoothly and Tom would visit and communicate frequently. He took care of the inspections as well without issue and some other things without charging us, which I appreciated. At the end of the project, we had some concern about the slope of our deck above the office. Tom and his crew came out and fixed it and didn't even mention the final payment until we were happy. Our remodelled office looks amazing. I'd gladly recommend LB Construction for anyone looking for a contractor and will contact them again in the future.
