I highly recommend Twin Pinnacles Construction. Twin Pinnacles redid my kitchen in 2017 and two bathrooms in 2024 and have done many smaller projects for my home. The contractor, Javier, is hands on and is reliable and trust worthy. All his employees work as a team and show respect for one another. They don't rush through their work. They take their time to make sure it is done correctly and of the highest quality. When things were delayed due to a supplier, they worked around their schedules. I can not say enough about this great company! read more

Twin Pinnacles reconstructed the supports to our front stairs above & below after it began coming loose from its foundation around the time of the pandemic-and we anticipated a challenge finding the crew to fix it.

Javier & his crew (always masked) arrived & assessed the situation & from start to finish were organized efficient and masterful as the photos illustrate......and especially important - highly professional & pleasant to work with I highly recommend them regarding repairs construction & painting. Thanks again Javier & Twin Pinnacles Crew!!! read more

I cannot understand why anyone would give Javier Diaz-Macias a bad review. After seeing what a good job he did on a friend's remodel in the Mission, we hired Javier to finish the 1000-square-foot basement of our home in Miraloma Park. The job expanded greatly, but this was not Javier's fault. We started to excavate and discovered a small underground stream just a few inches down. That required a bunch of water remediation, French drains and so on and excavating a good bit of the driveway to find the tie-in with the sewer line. The excavation revealed that the foundation didn't have a footing, and so the city required us to rebuild the foundation and do an earthquake retrofit. During that process, we discovered dry rot and so we had to strip the stucco, repair the dry rot and add insulation. We ended up basically rebuilding the house: adding new HVAC, new electrical new paint inside and out, new driveway and front walk, retaining wall in the back yard, pocket doors and new fireplace surround PLUS the original remodel that we had envisioned: adding a bedroom, two bathrooms, a family room and an art room on the lower level. We also added new windows, new roof and solar with other contractors. Javier was professional, positive, responsive, patient and flexible throughout this process, which took more than a year. When we had to stop work for a couple months to get more financing, Javier did that with good humor. He worked with only top notch subcontractors: the electricians, plumbers, HVAC specialists, wrought iron specialists that he hired were great. The architect that he introduced to us (after not being able to find an architect ourselves because our job was "too small") was terrific. His design transformed the house, adding large windows that make the lower floor so pleasant. Javier's staff guys were great as well. His painters are methodical, patient and amazing. When they get finished, your woodwork looks like it was lacquered, not just painted. His carpenters are master craftsman and his more junior guys do everything, and do so with a good attitude and a smile. Javier really cares about his clients and his work. To say that he is unethical is just not true. He follows through. He holds his guys to a high standard. If he does a daily check on your project and if he doesn't think something is up to par, he will make his guys redo it. When Javier was not happy with the prep work of the first stucco subcontractor, he fired that sub and hired a new stucco team that did a fabulous job. Plus, Javier also did some things for us that weren't even part of the project: He finished the crawl space under our house, adding a wood floor and lighting so that we could use it for storage. When the SubZero fridge that came with the house died, and the new one didn't fit the cabinetry, Javier had his guys build us a new facing wall around the new fridge. He also had his painters repaint an antique chest of drawers to match the trim in our new bathroom. He did not charge us for these little projects. Our next door neighbor was so impressed with Javier that she hired him to paint the exterior of her house. Seeing some of the comments here--that projects were behind schedule and over-budget--is par for the course in remodeling in our experience. You open up walls and floors and you find things you didn't expect (like underground streams and dry rot). Our remodel ended up costing three times what we expected. It took a while to get on the stucco sub-contractor's schedule. None of that was Javier's fault. He always let us know when things were going to cost more, or take longer. And even though we've had to hold off on landscaping for a year or so, we get so many compliments on the remodel that it's kind of embarrassing. It's true that sometimes Javier gets crazy busy and he might not get back to you for a day or so. That's true of me. Who isn't busy these days? But Javier always calls back and he is always ready to do whatever it takes to make you happy. I have never found him to be "missing in action." Never. If you're not happy with Javier and his crew, I suspect that you're not happy with life in general. If you're planning work on your house, hire Twin Pinnacles. We are still going to do our kitchen cabinets and counters, as well as a patio and a retaining wall in our backyard. We would not consider hiring anyone but Javier Diaz-Macias and Twin Pinnacles. We recommend him to all our friends, and to all Yelpers in San Francisco. read more

javier and his team have completed several projects for us - including a very major year-long one, adding a second level to our house and requiring significant structural work (e.g., new foundation alongside all the extras like new roof, stucco, painting). they've also done smaller projects like painting or installing shelves. always they are professional, communicative, responsive, solutions-oriented, and keep a super clean job site. javier provides detailed bids too and brings humor to every interaction. we highly recommend twin pinnacles to anyone thinking about a big or smaller project! read more

I just had my pre-1906 house painted by Twin Pinnacles. The house has been painted multiple times over the past 100+ years. Most of the time, very little prep work was done. I must confess that I also 'cheaped-out' on at least one house re-painting. Twin Pinnacles did a FANTASTIC job of removing the many, many layers of paint and spent almost 2 weeks just doing the prep work. The resulting paint job is just AMAZING. My old house looks almost brand new! But - what made the experience exceptional - was the fact that I didn't have to actually do anything - and there were no problems and no stress. Javier took care of matching and obtaining the paint from Benjamin Moore. His workers started on time, were pleasant to have around and were very respectful of my house. And - in additional - the price was extremely reasonable - roughly 60% of other quotes that I received. What was also beneficial is that Twin Pinnacles is a general contractor - so the additional work that I had them do (once I saw how well the painting work was going) was done by the Twin PInnacles crew - and not subcontracted out. I cannot agree with the negative reviews of Twin Pinnacles. I am an attorney. I do a lot of commercial real estate work (which includes construction) - and I have had no problems AT ALL regarding the way that Twin Pinnacles handled this paint job and the other work. I intend to use them in the future. read more

Javier Diaz has been our contractor and the contractor for many of my co-workers', friends' and family's projects over the past 20 years. We would never hire anyone else. Before I hired Javier, I had terrible experiences with absentee Contractors, and generally ended up coordinating the jobs myself. I was so happy to find a contractor who would answer my calls and was truly responsible for the work.Twin Pinnacles has remodeled our homes, kitchens, built decks, done seismic upgrades and painted multistory buildings to everyone's satisfaction. He is knowledgeable about all codes and regulations and has NEVER failed an inspection on any of our projects. The quality of his work is impeccable. He has a timeline and scope of work which he adheres to with each project, no matter what the size. Remodeling is a very stressful time in a homeowner's life and there are always unforeseen problems, which can cause delays and extra costs. I know many people who complain about their contractors and delays and extra costs, etc. - It seems to be the nature of the business. I have an older building and too have had extra costs and delays. I also admit that some were due to me changing my mind and not understanding construction, as well as the unforeseen. Extra time and money doesn't make anyone happy but it is a fact of remodeling. If there was any problem I had with workmanship Javier would fix and we were not ever charged for this repair. Javier is a hard worker and stands by his work. I am compelled to write this review today because I feel that these two reviews do not represent the company I know and have worked with and recommended, and will continue to hire and recommend. read more

After seeing what a great job Twin Pinnacles did with my neighbor's house, we arranged to have Javier Diaz-Masias replace our back fence. We have a number of large projects that we are considering so we figured this relatively small job would be a good test of what we could expect in a working relationship. His bid was detailed both in the scope of work and the payment schedule. It was also reasonable so we decided to move ahead. The job started on the promised date and the work was exceptional. One of our back corners did not match up with the adjacent yards so it required 3 right angles in less than 3 feet fitted over a segment of a retaining wall which had to be repaired. We just expected to have a funny looking fence so imagine our surprise when we found a lovely little nook and ledge which made the corner an accent area. In addition to this creative solution, the care and attention to detail demonstrated by the crew resulted in a beautiful fence. While we knew the crew would depose of their waste, they also cleared out a lot of detritus in our back yard saving us the trouble and making the yard look clean and well ordered. The quality of materials used were also of high standard. In addition to having good skills, the men who we got to know; Alex, Ambrosio, Isaias and Paulinho, were so nice. Having lived in the house nearly 40 years, we have had our share of construction workers in and around the house. Some were awful (particularly language) most were fine but these men were people we would be pleased to have as guests; polite, friendly, communicative and respectful of our home. When it was time to stain the fence we arranged to also have some window boxes painted and installed on the front of our house. The installation was difficult, made more so by my anxious and exacting oversight but Alex and Paulinho were terrific, providing us with a exactly what i wanted and all the while remaining patient and accommodating. All the work was done on time. The workers came when we expected, let us know when they were leaving for lunch and cleaned up every day. Javier came by at least once each day and usually 2 or 3 times a day to check on the progress of the work, to give instructions to the crew and to update us not only on what had been done but on the next steps. It was rare that we needed to contact him but when we did he got back to us in a reasonable time frame. While it is true that this was a relatively small project, we note how well people attend to small jobs as indicators of how they will handle larger ones. Given the construction boom here and how difficult construction companies are having getting and retaining skilled workers, the fact that these wonderful workers remain with their employer and clearly like and trust him, is yet another indication to us that we are dealing with an ethical and fair individual. After this experience, we have no qualms about using Twin Pinnacles on larger projects. And a final note-our other neighbor was so impressed by what he saw going on at our house that he contracted to have two decks replaced. These turned out beautifully as well so Twin Pinnacles has another convert. read more

I highly recommend this company!! Javier and his team at Twin Pinnacles did exceptional work on my SF 3 flat Victorian on Potrero Hill and the work was done for a fair, reasonable price. I am grateful to have discovered them. I initially contracted with Javier to paint the exterior of my 3 story Victorian and the interiors of two of the 3 flats, as well as to gut and replace two bathrooms. I chose his company over two others because of the recommendation of 2 neighbors and because his proposal came in at the lowest price among the 3 proposals that I solicited. A very positive review of Twin Pinnacles' from my neighbors who had the exterior of their home painted and all of their windows replaced was followed up by a second high recommendation from my next door neighbor for whom they did a complete kitchen remodel, window replacement and replacement of a deck and exterior backyard stairway. Once they got into my project and I saw the high quality of their work and how easy Javier was to work with, I decided to add to the scope of the project with the update of two kitchens and additional lighting. Finally I also added the replacement of the exterior entry stairs to the building, a major improvement which they did at a very good price and which looks terrific!! All of the work that they did for me was excellent! The team was very professional, detail oriented, very tidy and a pleasure to work with. The pricing was clear. As projects were added the contract was updated. We went over the pricing for each element. I knew where I stood at all stages of the work. There were no surprises. I have worked with several contractors over the years, for residential work as well as for the construction of 4 restaurants. I will return to Twin Pinnacles the next time I have a project to do. I trust them to do great professional work at a fair price. In my experience that's as good as it gets in the world of construction. read more

Javier Diaz-Masias and his Twin Pinnacles Construction Co. was recommended through neighbors on Missouri St. He has done many long term projects on that street, being recommend from neighbor to neighbor. We were extremely satisfied with the work performed by his crew and his subcontractors for various trades. We highly recommend Twin Pinnacles Construction and rate the company 5 stars. We own a 2 flat Victorian on Connecticut St and the kitchen/dinning room on the first floor never had been remodeled. Javier presented an interesting proposal w/ some very creative ideas, at a workable price - lowest bid was not our main criteria. The kitchen remodel involved gutting the rooms to the rafters hand floor joists. That revealed further problems with let to foundation work. Other problems emerged with the electrical services needing a complete rewiring and separating the mix-up between the 1st and 2nd floor. After the foundation work was finished, a german electrical floor heating system and floor tiles were installed (by Javier's expert subcontractor Isidro), plumbing had to be updated (by Javier's excellent subcontractor Eddy's Plumbing), walls insulated, more double insulated windows and door to garden completed the space. Now the kitchen was equipped with new appliances from LG, Maytag and Miele. Grohe faucets, Zephyr exhaust hood, custom cabinets (by Javier's cabinet builder) and great energy efficient lighting. A major work (by Javier's excellent subcontractor Byron - Flush Electric) was the rewiring of the electrical services, install separate fuse panels on each floor and a main service panel, in the garage, for the 2 PGE meters and just in case, a 220 Volts outlet. In a second phase, Javier with his expert crew of carpenters and painters (Jose, Isaias, Ambrosio y Paulinho) refinished the kitchen on the 2nd floor, installed new hood, did bathroom work on both floors, poured a larger cement landing to enter the garden, constructed a mezzanine in the shed, installed a Werner Al ladder to the attic and re-insulated the attic. We ended up painting the entire house and Twin Pinnacles crew lead by painter foreman Isaias did a meticulous job, specially in the preparation phase, which is the most important part and time consuming, for a lasting paint job. Javier managed this involved remodel phase by phase, discussing with us the alternatives and costs for the additional work that had to be done. As always in old house remodel projects, non anticipated problems appear as work progresses and have to be dealt with expertly and on the spot. If left for later or even brushed over, the could create costly problems down the line. At all times Javier kept us informed, proposed cost effective solutions. At all times he dealt professionally in addressing any problem and was always available for us. He inspected daily the quality and progress of his crew and subcontractors, making sure they had everything they needed to do their particular job. He and his crew did many extra works and favors for us as part of his outstanding customer services. read more

Javier and Twin Pinnacles Construction have completed two separate projects for us and we are very satisfied with the results. The first one was the successful solution to a persistent leak that others had failed to fix. The other project was some seismic retrofitting to our 100-year old house. In both cases, Javier has been a real problem solver, listening to our concerns, coming up with a plan that suited our needs, and explaining the work to be done, including drawing clear pictures as needed to show what was involved. The work was completed on time and done in a professional manner. His crew were all courteous, thorough, and very neat--they left the place cleaner than when they started! We would definitely call on Javier again for future projects. read more

Javier Diaz has done two construction projects for us. He is honest & worked within the time frame and budget agreed upon. I had access to him when I had questions. I found out about him bec. he works for a friend of mine who is a well known interior designer who appreciates the unique quality of the older homes in the bay area. She restores the architectural elements such as casement windows, moldings & fixtures that are great and tries to capture the charm of the original home rather than than tearing everything down. To carry out her ideas successfully a great contractor such as Javier is needed. One area of his expertise (strangely hard to find in San Francisco) is to match and install seamlessly, moldings in older homes such as our 1916 bungalow. The work he did also involved matching the original windows & replacing the exterior and interior moldings to mach the originals- perfect. I was not quite ready to tackle a bathroom renovation so I asked I asked for a referral to someone who could replace the bottom tiles of my shower to make it last until the next leg of our remodel. The guy did a less than perfect job. I reported this to Javier who came back and removed and replaced the tiles himself at no charge. read more
