I needed additional concrete parking at my house. Nick and his company, Dimension came through with fantastic work. The job was pretty straightforward but the land did have a slight slope to it. Dimension gave me great recommendations from their experience on number of piles, retaining wall, parking curbs, and even incorporated a pipe running under the concrete for future electrical system and irrigation that I requested. I would hire them again for any concrete work or anything else that they are willing to do. Their communication through the whole process was excellent, which is something that I value very highly. read more

Dimension built the large retaining walls (main wall: 11 to 12 feet tall x 120 feet wide; planter wall: 4 feet tall x 100 feet wide) and drainage systems as part of our landscape project on a steep slope. Before getting introduced to Dimension, I reached out to some other concrete contractors in the Bay Area; many of them didn't even respond perhaps because of the complexity in the job while others responded with quotes that were not backed up by enough details. Dimension's quote came in with a good level of detail with very reasonable price; in addition, it had all the paper work required by the city, from workers' compensation to liability insurance. When the actual work got started, we were really pleased to see good signs of a great construction company. The crews knew how to read plans, were highly skilled and they were really hardworking (to the point that we were worried they didn't take enough breaks!). Since there was quite a bit of demolition, the crew cleaned up our driveway every day before they left. Nick, the owner, was very organized, along with great support from the office manager Daniela. Nick checked in and communicated with us on a daily basis, and was very patience in listening and responding to our questions. He got all the equipment and materials in order and he was very experienced in dealing with field engineers and city inspectors. As with any large projects, we also had "surprises" that were not covered by the plans and had to make changes accordingly. Each time when a surprise popped up, Nick put our project's interest first and tried to make flexible accommodations, even though it meant he would make a bit less money out of such changes. His homeowner-first approach was in stark contrast with dishonest contractors who low-balled their quotes just to get into projects and then take advantage of the change orders to make money. Many thanks to Dimension, we couldn't be happier with the new walls and drainage systems. In so many ways, we were lucky to get to know Dimension through their excellence. And when neighbors asked for referrals, we had no hesitation in recommending Dimension. read more

I have been a customer of Dimension Construction since 2017. They did excellent jobs of clearing mud slide, building french drain along two sides of the house, cement staircase on a long sloped side and massive retaining wall at the bottom of the house located in Oakland hill in Montclair. In 2021, they did another excellent job of reinforcing part of foundation (originally built in 1906) in San Francisco with 4 ft deep steel encased cement foundation wall with waterproofing. They also built french draining around it and a few minor corrective jobs around in the Noe Valley, San Francisco house. Joao Nicolau, the owner engineer would come and do a thorough examination of the troubled area and come up with sound solution. The crew were very attentive to my questions and explain in detail. I would recommend the company for any construction job from demolition to reconstruction. Joao and his crew are professional, honest and diligent on their work. Try them for your construction work from small to large. read more

Nick at Dimension is the best! I recently replaced my home's foundation in San Francisco. I've done many remodels in San Francisco, but this really seemed like a big job and one I was quite nervous about. I got 10 bids, wanting to make sure I would be treated fairly and that I would understand what this job entailed. The bid I got from Dimension was the most professional with itemized costs, the shortest completion timeline, and the best price. One of the other bids simply stated: "Replace Foundation" and a price. Another contractor said it would take 2 maybe 3 months. Dimensions completed the job in 4 weeks! Each step of the way the job was done with precision. I knew I was in good hands when I checked on the work after the old foundation was removed and I could see the trenches they dug and the concrete slab they cut were all done so perfectly and the job site was clean! I was not expecting a real mess but they run a tight ship. With many of the other contractors I met with, it felt like if I chose them I would be in their spider web; stuck. Nick put me at ease and I could tell he understood every facet of what needed to be done. These guys are pros. I couldn't be happier and I feel like Dimensions brought me through quite a difficult time with great customer service and exceptionally professional workmanship. read more

We looked at two sidewalk replacement jobs recently on our block. One by Dimension Construction, Inc., the other by an unlicensed builder who shall remain nameless. Dimension's job took only a few days, while the other other job (of similar scope) dragged on for many weeks. Nick Nicolau, Dimension's owner, holds three state licenses: A (Engineering), B (General) and C (Demolition Specialty). I was impressed on many levels at the professionalism Nick and his crew exhibited on our project. First, he is incredibly responsive. How refreshing to have a live response when you call, always! Second, Nick has many years of experience, and made our job (huge and daunting for us) look easy. His crews handled this with utmost care and safety. Nick got all the necessary permits, and it was clear his work is highly respected by the City's Engineering Department. The job itself involved demolition and replacement of our driveway, sidewalk, curb and gutter across the front of our property. We expanded our driveway to accommodate two cars. City trees had damaged the sidewalk, and his crew expertly extracted the stumps and roots, which had grown dangerously around a PG&E gas main. His crew coordinated with PG&E and its crews to ensure this was done safely. Dimension formed openings for new trees at the curb, with irrigation conduit built in. They also expertly replaced flagstone walk from our front porch to the sidewalk. Nick also made sure our roof water would drain out to the curb through a buried line. Throughout the job, which lasted a total of seven actual work days (10 calendar days), the crew kept everything clean, well organized and safe. This work exceeded my expectations in every way. They are great artisans. Artists, really, and I wholeheartedly recommend them. read more

Dimension Construction to the rescue! Thank you for taking care of us local neighbors. I was happily surprised they took on what I considered a tiny job in front of the house. - Company owner Nic came to evaluate and was patient with our many questions. He is an expert in the trade AND in handling all the local permitting requirements, which is a big deal for us - Daniela, my main contact for estimate/contract paperwork, invoice, etc. was amazing: quick to respond, thorough, and patient with the additional questions I had along the way - We reached out to several companies but am SO glad to have decided on Dimension, for their expertise and professional yet kind communication - The team fit us into their schedule and completed the project quickly. From demolition to haul away to prepping to the final fill and level; the area was always left as clean as it could be Dimension Construction will be out first call for future projects - consider them when planning yours! read more

Great job! It looks like a major commercial sidewalk work, and it is in the front of my home! The crew came all with masks and were at all times respectful and careful with plants and property. Dimension handled the permit application and called the utilities, and kept me appraised of progress, as city inspections were needed. They worked around the rain schedules to avoid delaying the job unnecessarily and they were very flexible and super-reasonable on last minute changes. I would work with them again any time, and I surely recommend them! read more

Used dimension for removing old concrete from garden. Lowest offer of three, showed up on time and impeccable work. Would use again.
