Better Together Builders Lic#1047689 818-858-9840 [email protected] **Please note: Due to high demand, we are no longer able to do projects that are under a budget of $7000.**

"I hired Better Together Builders for a major home renovation and have paid over $130K toward the project. While some work was completed, my overall experience has been disappointing due to delays, unfinished tasks, and a lack of attention to detail. I am currently pursuing legal action against this company for their failure to fulfill contractual obligations and for the damages caused. Specific examples from my project: • Electrical work was left incomplete, requiring me to hire a licensed electrician at my own expense to finish it. • Several areas were installed without proper preparation, resulting in chipped slabs, misaligned cuts, unpatched drywall holes, and exposed wiring. • Communication and follow-up became inconsistent, and I often had to chase updates to keep the project moving. • Extended delays caused me to lose months of potential rental income, while I also had to pay for temporary housing. This review reflects my personal experience and is not intended to cause harm, but to inform others. If you decide to work with BTB, I strongly recommend documenting every stage of the project, inspecting work before releasing payments, and ensuring all contracted items are fully completed before signing off."

"Our experience is identical to what other reviewers shared. And yes, you should run from this company as fast as you can. Do not buy what Abraham shared that the payment must be made when the inspection is passed. Check the Business and Professions code yourself, the payment only needs to be made when the job is completed. It is very COMMON that the job is not even done or poorly performed even the inspection is passed. Here are the issues that multiple families including us run into with this company:: The project was delayed for over 9 months. No one manages the job. He often employs young men from his own Jewish community. They are enthusiastic but had no prior experience. The worse part is that they don't get paid. Two of them even set up a new construction business knowing Abraham will never pay them. Subcontractors can put your house on lien also. Many reviews you see on Yelp, Google, Angi are NOT genuine. Even the references are fake with hindsight, we were given 2 references. One reference shared the exact same accent as the PM. The other reference was initially happy with their work, but then reached out to us and shared a similar horror story with them like what we experienced. You will lose a lot of $$$ on materials as the subcontractors will somehow leave a thousand dollars worth of quartz at home. Maybe they want to compensate for the money Abraham owed them? Let me tell you, reordering materials is not fun."

Power, Construction Masters ™ is a family owned, full service, general construction company with 36 years of experience in Kitchen and Bathroom Remodeling, Garage Conversions (ADU), New Construction, Room Additions, Roofing, Painting, Flooring, Windows, Stonework and more. Licensed #762655 & #623586, Bonded #SC1025172 and Insured #1454306. Construction Masters ™ has gained a reputation for excellence as one of California’s most respected construction firms as well as an industry leader within the residential, corporate and restaurant/retail construction markets. Contact us and make your dream a reality! Corporation - Moshe Cohen Inc.

"We purchased our home knowing it would need extensive remodels, and we were admittedly nervous after hearing so many horror stories about planning hold-ups and unreliable contractors. We did our homework, researched over 8 companies, and met with 5. The moment we met Moshe, we knew he was the right person for us. He was the right price, had the right temperament, the right balance of speed and detail orientation, and most importantly, he listened to what we wanted. While other contractors tried to push us into their vision, Moshe respected ours and guided us with smart advice that improved the design for real-life living. It was truly the perfect match. From day one, Moshe was on top of everything. He always had a team on site, and they worked tirelessly through what was no small project: three bathrooms, moving the laundry room, relocating the kitchen, laundry and 2 bedrooms, installing new structural supports, moving multiple windows, moving a slider door and so much more. We even made changes along the way, and he accommodated seamlessly. Incredibly, all of this was completed in just three months, fully permitted and signed off by the city. The quality speaks for itself. Every wall, cabinet, and tile is perfectly placed. During our walkthrough, we nitpicked small things, but Moshe was already ahead of us, pointing them out himself and immediately bringing in his team to perfect the final touches. He also gave us the “Moshe Guarantee”: if anything comes up in the months or years ahead, just call and he’ll send someone out. That level of pride and accountability is rare. What impressed us just as much was the caliber of his entire team. Every single person Moshe brought onto our property was kind, respectful, and excellent at their craft, from Miguel the electrician to Victor, who built out our wardrobe, hung shutters, and took care of countless details. It was clear that Moshe surrounds himself with true professionals. I truly cannot recommend Moshe and Construction Masters highly enough. They turned a daunting remodel into a smooth, exciting process, and the results exceeded our expectations. We will only ever use Construction Masters in the future, and we recommend them wholeheartedly to anyone looking for quality work and peace of mind."

"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

Custom Home Builders questions, answered by experts

An A-frame home can be cheaper to build than a traditional house, but that is not always a given. Prices can be fairly similar in some cases, depending on the location, design, and necessary site preparation. Costs for an A-frame typically run between $100 to $200 per square foot, which is comparable to the cost of a traditional home. The cost of an A-frame can come in under those numbers if you opt for a prefabricated kit.

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

Check reviews, compare quotes, and verify licensing. Ensure the builder has experience with modular construction.

On average, the cost of a home builder is about $150 per square foot, but that price can range from around $100 to $400 per square foot or more. That puts the typical price range of a standard, 2,000-square-foot house between $200,000 and $800,000. Some factors that affect the price of hiring a home builder include the following:

  • Location of your home and the living cost in the area

  • Type of foundation and framing you choose

  • Quality of the building materials

  • Footprint and layout of the house

  • Number of stories

  • Builder’s experience
