EXCELLENT Based on 172 reviews Aaron F.September 10, 2025Verified I had an excellent experience with Jacob Hirschorn and Ground UpBuilders! They came out to inspect a problem I was dealing with after I had already received a quote from a big-name company. Right away, I noticed how professional and detailed they were. They carefully assessed the situation, explained everything clearly, and recommended addressing the issue in two stages to make sure it was done right. Thanks to their honesty and thoroughness, I discovered that the big company's quote was not only overpriced but also wouldn't have fully solved the problem. Jacob & his crew saved our family a lot of money and gave me peace of mind knowing the job was done correctly. I highly recommend Jacob & Ground Up Builders if you're looking for a contractor who is professional, trustworthy, committed to doing quality work & a long lasting relationship. Barbara O.September 2, 2025Verified Jacob Hirschorn and Ground Up Builders did a high quality job on a residential apartment unit that needed mold remediation and tile abatement, followed by replacement of very old bathroom materials and fixtures with new of same. The finish product looks very professional. Jacob managed the field crew with Ground Up's long-standing pool of workers, including Manny and Cesar. Jacob did not over-promise anything and stayed on schedule. The office team was very helpful as well, including Mary Jane and Tish. It is best to determine ahead of time if you may need a THP with the City of LA and establish who will purchase materials. Thank you Ground Up Builders. You delivered. John F.August 26, 2025Verified We have now used Uzi and his team for three jobs: When a car crashed into a front bedroom, for a bedroom & den with flood damage, and a recent remodel including repairing hundred year old hardwood floors, windows, etc. He gets all 5 stars from us. He does what he says he will, and he does it on time. He has a fine crew that really came through for us. Absolutely 5 of 5 stars. Thanks for everything, Uzi!! Angelo D.August 19, 2025Verified I've worked with Ground Up Builders for many years, and Jacob has always been my go-to person. He is extremely knowledgeable, patient, and takes the time to share creative ideas--he recently spent a long time helping me plan my kitchen remodel. His estimates are fair, right in line with other general contractors, but what sets him apart is his honesty, integrity, and the value he brings to every project. Over the years, Jacob has replaced carpeting with LVT flooring (and even secured me a great discount with the flooring company) and corrected the poor work of a previous contractor on a decorative window. Every experience has been positive, and I truly trust his judgment and workmanship. Ground Up Builders is always the first company I call, and I highly recommend them to anyone looking for quality work and a contractor they can rely on. Hank C.August 18, 2025Verified Huge fan of Ground Up's work. Jacob and Uzi have guided us through planning and permitting for several residential projects with amazing know-how, attention to detail and professionalism. Certainly the most attentive and thorough contractors we've dealt with. And when we lost our home in the January 2025 Eaton Fire, they went above and beyond to help us navigate our insurance claim and to help prepare for our possible ground-up rebuild. Highly recommend them for any design or construction needs, big and small. Hector H.August 13, 2025Verified I purchased my first home with my dad last year and really wanted a pool in my small backyard. I was worried it wouldn't be possible just due to the huge dirt hill we had taking up half of the space. Adi Aiish at Ground Up Builders and Marcos Rojas took on this challenge and let me tell you, they absolutely did not disappoint. They took my plain backyard and turned it into an oasis, equipped with a heater for the pool AND the spa, as well as a built-in, natural-gas grill and countertop and tied it all together with a stunning planter and moody lighting that really brought the set up to life at night. I highly HIGHLY recommend these guys for anybody's future home upgrades and projects. Thank you so much for also getting this done quickly and safely!! Josh C.July 22, 2025Verified We recently worked with Adi Aiish with Ground Up Builders on a full guest bathroom renovation, a sunroom refresh/remodel, new flooring, and even a brand-new roof--and I can honestly say this experience exceeded all expectations. From the very start, Adi was engaging, knowledgeable, and incredibly easy to work with. He treated our home with the same care and attention as if it were his own. Every detail--from tile selection to finishing touches--was handled with precision and pride. What really sets him apart is his consistent presence and open communication. No question was too small, and he was always available to walk us through updates or decisions. He took the time to make sure we understood the process every step of the way, which made a huge difference. He was also incredibly respectful and kind around our family--our kiddo looked forward to seeing him and his team! The work site was kept clean, safe, and organized, and his team was always professional and friendly. It's rare to find someone who blends high-quality craftsmanship with warmth and reliability, but Adi truly feels like part of the family now. We're already planning to use him for future projects and highly recommend him to anyone looking for a trustworthy, top-tier contractor. Hands down, one of the best decisions we've made for our home! Likequse2be A.June 21, 2025Verified Had a great experience using Ground Up Builders. Amir and Sean are amazing. They did great work and helped us navigate everything with our insurance company. Patricia K.May 31, 2025Verified When looking at reviews we consider the preponderance of evidence, which often leads to questioning an outlier, such as an extreme negative review when all others are positive. We had a very comforting first meeting with Uzi which led us to ask for a quote. The quote included due diligence information which further put our minds at ease, and we hired Ground Up Builders for a complete kitchen remodel in early 2024. From that experience we hired Ground Up Builders for 6 other projects: new roof plus solar panel installation, complete remodel of guest bathroom, master shower retile and new glass door, replacing rain gutter downspouts and adding gutter guards, refurbishing wooden/glass front door and threshold, and adding a gate and landing to hillside garden from steps on side of house. We will unquestionably hire Uzi and Ground Up Builders again for any other home improvement projects. Uzi and his team are extremely personable, do excellent work, communicate well, and there were no cost surprises. Very highly recommended. Jacquie B.May 29, 2025Verified I've worked with Ground Up Builders on several projects over the past 15 years, and they've consistently delivered outstanding results. Most recently, they completed a full remodel of my home--an 8-month project that was delivered on time and on budget. That alone speaks volumes in today's world. Uzi was incredibly helpful throughout the process, offering thoughtful ideas that made the design not only beautiful but also future-proof. His professionalism is unmatched, and he leads a team that is both reliable and respectful. They showed up consistently, communicated clearly, and always cleaned up after themselves--a small detail that made a big difference. Thanks to Uzi and his team, I'm now living in my dream home. I wouldn't trust anyone else with a project of this scale and importance. Uzi and the Ground Up Builders team are worth every penny and more!
