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. read more

We cannot recommend Ground Up Builders enough! They converted our two-car garage into an ADU and did a truly amazing job. They finished ahead of schedule, communication was great throughout the process, and every single worker we interacted with was professional, kind and courteous. Uzi runs his business with both warmth and integrity. He generously answered every question we had (even the stupid ones!), and offered a lot of valuable advice too. We particularly appreciated that he kept his promise to not go over budget. There wasn't a single change order, even when there was an unexpected issue with the sewer line - he explained that the contingency would cover the additional costs. Such a relief knowing that what he bid was what we'd pay! Special shout-outs also to Marvin, Raphael and Nathan who were a pleasure to work with. We highly recommend Ground Up Builders! read more

It appears this guy is only concerned with big costly projects. He knew this was a very small space yet still opted to come out and look. His only interest was what the insurance was going to pay. He seemed upset we had 2 other contractors come out to give competing quotes. He never got back to me, I had to ask him if was sending a quote and he told me no. Very unprofessional company focused solely on how much he would make off the project read more

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! read more

We needed to remove a bath/shower tile surround to re-waterproof and retile, and replace the fixtures. We went with GUB after getting their name from a tile vendor and meeting with more than one alternative. GUB were the most expensive by far but also were the most responsive and had the most professional and comprehensive bid. All of the legal paperwork and their license information was included, along with a detailed scope of work and examples of past work. Adi Aiish was our Field Manager. He's friendly and very responsive and our overall impression was that the additional cost would be worth it to have a professional job. To be succinct, here are the pros and cons from the project: Pros: - Responsive field manager - Very fast demolition and quick work overall - Crew was hard working and polite, especially Antonio - Tiling work looks good Cons: - When a piece of plumbing broke and flooded the ceiling below, the response was that things like this happen. It took 5 days for the field manager to take a look and offer an apology. - During demolition, the mess was off the charts bad, leading to a lot of cleanup for us afterwards. During the project only the floor was covered (and on one day not at all). I've had other renovations done that were much cleaner. - The finishing was not as polished as I would have hoped. The caulking around fixtures was messy, the tile tilted slightly revealing the old seam around the floor, painting that was in the bid was only one coat until I asked for more. I think the M.O. is to work very quickly and fine tune the finishes only after being asked. Overall we're happy with the result but would have liked them to go a little slower to be more careful. read more

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. read more

In 2023, Ground Up Builders finished building an ADU for us as part of a garage conversion. This became a unit for my parents to live with us. Between 2016 and 2020, they also remodeled our kitchen and two bathrooms. Every time we have needed some work done, I call Uzi. Basically, there is no contractor/builder like this--it is now 2026, and I called Uzi today because of a concern about a leak that we discovered with the recent rains. He sent out his team immediately (eg., same day) and they discovered that squirrels had caused some damage. They covered the area to prevent further problems until we can get this fixed. Ground Up Builders is an incredibly responsive and highly professional company that does outstanding work and continues to be conscientious and gracious with any follow up issue. I am grateful for Uzi and continually impressed by his team. You won't ever go to anyone else after working with them! read more

Ground Up Builders have been amazing to work with!! They are professional, offer great suggestions, and produce sold work. Jacob is amazing!! He truly cares about the work that is put into your home as if it's his own home. He treats you like family. For us, Jacob went above and beyond. We live in El Monte and the city is not easy to work with. They kept giving us problems with permits, etc. Jacob didn't just email them and wait around. He drove over in person time and again to resolve the issues and speed up the process for us. If you want something done in your home, you can trust the team at Ground up Builders! read more

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! read more

Ground Up Builders - New Addition - Family Room looking out to new deck - General Contractors Near Me

We've worked with Uzi and the Ground Up Builders team on a number of projects in our home -- from gut renovations of two bathrooms to opening up walls in our kitchen, installing new lighting and electrical, mold remediation, and refinishing all the floors in the house. Oh! And when we had an emergency plumbing situation a week after moving in having nothing to do with his work, Uzi sent his team immediately to help. While Uzi is incredibly capable with major renovations, he approaches even the smallest jobs with the same level of care. Truly, no job is too big or too small for him. Uzi is smart, thoughtful, patient, and deeply experienced-- he's like a walking encyclopedia -- he has answers to everything! He's also an amazing communicator -- always available, always willing to explain every step. We're not the easiest clients (we're very particular and even more indecisive!), but Uzi never once made us feel rushed or like we were a burden. He always walked us through every option and every choice. His team of painters, tile installers, plumbers, handymen, and more -- are all so kind, skilled, professional, and respectful-- always putting on booties before entering and cleaning up after themselves when they finished. We always felt comfortable with the Ground Up team in our home. We appreciate Uzi more than we ever thought it was possible to appreciate a contractor. In short, we recommend him and Ground Up without hesitation. read more

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. read more

Tom and his team were top-notch. From the initial consultation to pivoting several times based on new design approaches and availabilities of patio tile, he was patient, friendly and always willing to work with me. We had to remove an old broken jacuzzi from a raised patio decking and decided to expand the patio and create more livable space instead. Tom's crew was efficient and fastidious, and the price he quoted was the price we ended up paying, despite delays and issues outside of anyone's control. Really happy with the results. read more

This was our first time going through any type of remodel, so we were seeking a contractor and company with a great reputation along with demonstrating patience, competence, and professionalism. My wife found Ground Up Builders on Yelp and we got lucky enough to have Jacob as our Project Manager to come give us a bid and explore ideas. Long story short, Jacob was awesome, and we really felt as if this was his own home and took time and empathy from all angles of the project from concept to completion. We live in West Hollywood, so not an easy city to work with for permits along with an incompetent HOA, which Jacob navigated effectively whereas I feel others would almost give up or deprioritize simply bc of the hurdles in headaches. Not the case with Ground Up... Their overall work and craftsmanship were spot-on across all aspects of the remodel fit our vision and managed to get very close to the estimated time of competition even though the City and HOA were not on our side. Our new Kitchen looks amazing with a spa-like bathroom and impressive new flooring. Excellent work on all fronts. I would recommend Jacob and Ground Up Builders to anyone in the LA area looking for a remodel, large or small. I've heard a lot of scary contractor stories but quite the opposite with our experience and I would love to work together again in the future, hopefully not too too soon though, ha. read more

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!! read more

I had the privilege of working with Jacob and his team. He is incredibly dedicated and personally invested in his work. He truly listens, communicates with care, and pays attention to every detail. He and his team are meticulous, thoughtful, and hardworking, while also being very respectful of the home and space. They're not only trustworthy but also genuinely kind and caring--it felt like a real personal and collaborative relationship throughout the process. I highly recommend. read more

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. read more

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!! read more

When we describe our remodel experience to people, people are shocked at how smoothly it went. Ground Up is a unicorn among contractors. Our cost and time estimates were correct. 8/9 months for a bathroom and bedroom addition, kitchen remodel, new floors all over and updates to windows and current bathroom, and new patio. We didn't start out with that much to do, but of course we did expand the scope once we discovered how great Uzi's team was at getting things done - and it didn't add much to the time. We figured it was best to do as much as a we could while Ground Up was on site and it could get done quickly and reasonably. Uzi cares endlessly about the quality of his work, as well as the timeliness of it. He knows his stuff and has a good eye. He runs a big operation, but he manages it so well that it ends up being a big plus to the client - motivated and friendly workers who we really liked, crews that always show up day after day, everyone really working hard to get things done well and on time. We've been through construction before, so we know it's sort of unheard of to think of your contractor like a friend after going through the hell of construction. So glad we went with Ground Up, and im sure we'll use them again if we ever need home improvement again. read more

There's nothing quite like the feeling of being a satisfied customer and sitting down to write a review of a business that I first noticed because of all the other satisfied customers. Does not happen enough, that's for sure. From the initial late-night reply & follow-up (to my late-night inquiry) from Eric, to meeting Avi the next day (!) to discuss our budget and options --- GUB immediately stood out as a company that takes their work and their customers seriously. I met with a few others before GUB and was getting a sense that no one was going to care about our little project given that our max was at or below the standard minimum, and that everyone seemed quite busy already. The only other company I could find that even remotely compared to Ground Up in terms of reviews and quality of work, sent what I would call a junior contractor who spent a grand total of about 3 minutes here before saying something like "Not to be mean or anything, but we're kind of a big company..." lol. No thanks to him, I'm guessing. Avi completely shattered my expectations from the get-go. He asked thoughtful questions and gave thoughtful answers with resourceful ideas and creative possibilities to help us track down that illusive buck bang. I could tell immediately that he genuinely cares about the work and the process which, oddly enough, includes the clients too! Hooray for the customer, someone still knows we exist! In the end, Avi remained both the only one willing to hit our number and the only one I actually wanted to work with. The next lowest bid was well over $5k more, by a far less polished contractor, who couldn't even include everything from our list. The difference was so stark, in fact, that some family back east were quite suspicious at first. I could not blame them! It seemed way too easy!! Thankfully, no one remained suspicious for long. Avi was a rock. He got right in here after contracts were signed and during the various delivery delays he remained patient, checking-in, and at-the ready. Also -- always available via text or call as we had various moving parts in terms of shopping for sizes of things, and some custom elements reliant on other things. When we finally won our game of musical vanities that caused weeks of delay... Avi and his team --- who were all very nice and respectful btw --- were right back here in a matter of days. Here's what you want to know: Avi & GUB delivered exactly as promised while practicing straight, honest, good faith, handshake business, with truly competitive pricing. He was always engaged and often times waiting on us (or Home Depot, rather) to continue the work. He showed experience, creativity, resourcefulness, patience, communication, trustworthiness, humility, and integrity -- in addition to just being a super nice guy who really cares about the work. I couldn't recommend Avi or GROUND UP BUILDERS enough! Stop searching and call them. You're welcome! read more

We could not be happier we chose Ground Up Builders to help us with our major remodel this year. Company owner Uzi stepped in as a late recommendation after a previous contractor wasn't cutting it. He gave us an accurate estimate within a short span of meeting us, and within a couple of weeks, our house was gutted and the project was on its way. His team always showed up (often even on Saturdays), was always on time, worked hard, managed additional requests and changes swiftly and with grace. Uzi himself was responsive, fair, kind, even-tempered, and honest throughout. He stopped by often and as necessary. The entire team was creative with problem-solving... and actually, there were no big problems to solve! Entire project was done in less than six months. Big recommend! read more

I live in Malibu in an area that burned severely. we had a lot of damage to our house from the fire. we had such an amazing experience with this company, and Uzi himself and his team before, that we decided to hire them again. it's been the best decision we made since the fire. The workers are extremely professional and courteous and caring, and always communicate well as to next steps. Uzi gave an estimate within 48 hours, which was extremely fair priced. if I could give 10 stars I would! Their team can do anything you may need. I would highly recommend Ground Up Builders for anyone looking to rebuild or remodel. And the price was better than any other estimate we received. Thank you Uzi! read more

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. read more

I hired Uzi and his crew to turn in unfinished area of my house into an office when my girlfriend and her son moved in with me and not only where they uniquely tuned to the design elements that I wanted for my workspace (including custom networking and power and lights) they were also very sensitive to not disrupt our brand new family life as we adjusted to all living together. I plan on using them again for a deck project and hopefully more after that. I cannot endorse them enough. A+ read more

we had a fantastic experience working with Avi and his team at Ground Up builders and design for our modest home renovation. Never having done this before and needing to live on the premises at the same time it gave us lots of apprehension - but Avi always remained professional, communicative, and guided us through the whole process, offering to help for anything we needed. they worked hard to keep the site as clean as possible for us during the time, and it was clear Avi's goal was the quality of work and our satisfaction. he has an extremely capable team such as Ovin and Idilio, who are experts in their own right, and after seeing their craftsmanship, thoughtfulness of function and attention to detail, it gave us great confidence in anything they tackled. Many things shifted and came up during the process due to it being an old house, etc. and it always felt like it was a team effort to solve those issues the best and most budget conscious way possible. Avi's fantastic attitude, fairness, and work ethic meant we didn't have to worry or dread if and when construction issues arose. I highly recommend you give Ground Up Builders and Design a shot at your next construction project, you won't be disappointed. read more

My solar was not working any longer, I had gotten them in 2006 by a company that was no longer in business. Uzi had been keeping an eye on the meter for me over several years while doing other work at my house. When he suggested it was time I knew I could trust him. His Ground Up crew not only made sure that the newest solar technology replaced my old panels, but installed them in a direction that gave me more coverage on my flat roof. They made sure to check my roof and resurfaced it before the big rains. Despite the big demand they had for customers I never felt that I was not being taken care of and my questions were always answered right away. The crew also cleans up when finished and even took some extra things I had wanted taken away with their trash. I highly recommend them. read more

We had the pleasure of having Jacob help us restore our home after a large flood. The project scope included a full kitchen remodel, one full bathroom remodel, as well as new flooring throughout. Jacob was attentive, friendly and most of all genuine. As first time homeowners, having someone we can trust throughout the process was very important. Jacob was very reasonable and always kept our best interest in mind. We felt very grateful to have Jacob not only manage the entire project but provide us guidance throughout the construction. He made sure the quality of the house was not only up to our standards but also up to his. Many times, he asked the crew to redo certain things despite us not catching those imperfections. Amazing! Jacob always made sure we were happy, even at one point offering to redo the entire shower floor due to some issues with the material. The peace of mind when working with a competent and professional project manager was well worth the money. Out of all the bids we got for our project, Ground Up was not the lowest - but after meeting and talking to Jacob, it was a very easy choice. He was very honest and thoughtful - and I can't stress how important that is when it comes to renovations with lots of money involved. We have future plans to do more renovations and have no doubt we will be reaching back out to Jacob to help us! If you're looking for help with your renovations, make sure to ask for Jacob. He will take care of your house like his own! read more

Ground Up literally just finished a bathroom add-on for me. Every step of the process was easy and stress-free. From the planning to the actual construction, every question or possible concern was addressed and explained in a patient and kind manner. The work itself was great.

Jacob was my contractor for my kitchen remodel. I am very pleased with the results of how my kitchen came out. I really appreciate how he acknowledged my budget and provided solutions to fit what I wanted to achieve. He provided suggestions that I wouldn't have thought of which turned out very well. He is very customer centric and made sure to go out of his way to ensure I was happy through the whole experience. I would be lying if I said there weren't any hiccups/obstacles during the project, but Jacob made sure to hold himself accountable and resolve any issues and make sure I was happy with the results.
