EXCELLENT Based on 178 reviews Nora S.October 21, 2025Verified 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. KC B.September 26, 2025Verified 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. Heather C.September 25, 2025Verified 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. Kristy K.September 16, 2025Verified 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! 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!!
Why Invest in a Home Gym?
The decision to build a home gym is about more than eliminating the commute to your local fitness center. It’s about investing in long-term wellness, privacy, and flexibility. Your gym becomes a space that works around your schedule, not the other way around. No waiting for machines. No distractions. Just results.
But beyond convenience, a custom gym increases the value of your property, especially as health-focused amenities become more desirable to homebuyers and tenants. It’s also an opportunity to design something that aligns exactly with your needs. Whether you’re lifting weights, doing yoga, following a high-intensity interval routine, or training with a physical therapist, your space should support the way you move.
At Ground Up Builders, we approach every gym project with this in mind. From layout planning to final equipment setup, we ensure that your space feels intentional, motivating, and professional.
Designing for Function, Comfort, and Flow
A successful home gym isn’t just about dropping a treadmill in the corner; it’s about optimizing layout, lighting, and materials to create an environment that promotes focus and movement. We begin every project by understanding your goals and workout style. Do you need space for free weights and resistance training? Do you want mirrors for form checks or wall storage for mats and gear? Is noise control a concern? How many users will share the space?
These questions help guide our design decisions. We consider ceiling height, ventilation, flooring material, lighting options, and acoustics, all key elements that separate a great gym from just another room with equipment in it.
We’ve helped homeowners carve out dedicated fitness spaces in garages, basements, and additions, and we’ve created wellness studios in multi-use properties and commercial buildings. The common thread is intentional design and quality construction.
Building the Right Infrastructure
One of the most overlooked parts of home gym construction is what’s happening behind the walls—and underfoot. The right foundation is critical, especially when the space needs to support heavy equipment or dynamic movements like jumping or weightlifting.
We install flooring systems designed to absorb impact, protect joints, and reduce noise. Rubber tiles, foam padding, or engineered subflooring options are chosen based on your workouts. We also take care of climate control, electrical needs, and reinforced framing where equipment like racks or wall-mounted pulleys may be installed.
Lighting is also a key factor. We use layered lighting strategies to avoid glare and shadows, making sure your gym stays bright and energizing throughout the day. If natural light is available, we incorporate that as well, because a well-lit space is one you’ll want to use.
Equipment Planning and Space Customization
What goes into the gym matters just as much as the room itself. Once the layout is finalized, we help clients plan for the right equipment based on their goals. That may include power racks, cardio machines, functional trainers, recovery tools, or smart mirrors for guided virtual training.
For businesses or multi-user facilities, we also plan zones within the space, separating cardio, strength, stretching, and recovery areas to avoid overcrowding and keep movement smooth. We build storage solutions to keep the gym clean and organized, including built-in shelving, wall-mounted racks, and hidden compartments for smaller gear.
If you’re incorporating technology, TVs, smart speakers, integrated apps, or touchscreen interfaces, we design the electrical and network setup to accommodate those features without clutter or lag.
.
Soundproofing and Safety Matter
Home gyms often generate more noise than you realize, especially in shared buildings or homes with thin walls. That’s why soundproofing is an important part of what we do. We install insulation, acoustic panels, and sealants to help keep your workouts quiet and prevent disturbances, whether you’re dropping weights or blasting your playlist.
Safety is another priority. We use slip-resistant flooring, reinforced anchors for mounted equipment, proper ventilation systems, and ensure all wiring and outlets are placed strategically to reduce hazards.
For families with kids or pets in the home, we also provide guidance on access control, locks, and safety mechanisms to protect the space and its users.
Professional Execution from Start to Finish
At Ground Up Builders, we don’t just design—we build. Our team manages your home gym construction from planning to the punch list. We coordinate permits when needed, handle demolition and prep, and deliver clean, professional finishes that stand up to heavy use.
Our approach is always personalized. We work around your schedule, keep you informed at every phase, and respect your space like it’s our own. Whether your project is part of a whole-home renovation or a standalone upgrade, we bring the same level of care and quality to every build.
Wellness Starts with the Right Space
Your health is one of your most valuable assets. Building a home gym is a commitment to yourself, and it deserves thoughtful execution. From compact home studios to full-scale private fitness centers, Ground Up Builders brings unmatched experience, creativity, and craftsmanship to every project.
We help you create a space that’s motivating, efficient, and designed for real results, so you can focus on your fitness goals without compromise. If you’re ready to create a space where wellness fits your lifestyle, let’s build it from the ground up.
