"Our experience with Suj and So Cal Builders & design was very pleasant. They executed a high quality upgrade to our prior home before we sold/upgraded. We did not want anyone else to renovate our new house. Every step of the remodel was handled in a timely manner. And, honestly, Suj is quite humorous; he creates a very nice environment to be around for his team and clientele."
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"Jorge, Andy and their team at A1-Builders were knowledgeable, honest, reliable and above all always available to answer any questions we had. They helped build a 2 bed 1 bath 600sqft addition to our home during the lean months over the pandemic. We had multiple projects (pool, patio, retaining wall) going on at the same time with other contractors and the crew from A1-Builders were by far the most professional. They always made sure that they left their work site clean after each dayâ s work. Jorge will definitely be the first person I call for our next home project because I know that even if he does not have the time to do the work, he will always guide me in the right direction. Thank you again to the entire A1-Builder team!"

"My wife and I purchased a home built in the ‘70s that was in good condition but in desperate need of a complete remodel. We had a clean, modern style in mind for our growing family and needed an architect to help us turn it into an actual design. That’s where YNG Architects came into play. We selected Yenny Ng and his team for design after interviewing several other firms because during the walk-through (a) he quickly played off and expanded upon our ideas, (b) provided pragmatic insight into the implications to build and construction, and most importantly, (c) had a gentle but confident manner that matched well with our working style. We were not disappointed. Over a period of several months we went through a systematic design process. Yenny and his team listened to our design preferences and took cues from example photos of design elements we admired. He lent his expert opinion and personal perspectives to balance pragmatic build versus splurging where we wanted to splurge (bi-fold doors between the indoor and outdoor space, yay!). He and his team worked well offline where we often exchanged and updated designs by exchanging emails and annotated PDF files—this was very productive as my wife and I both have demanding careers. He and his team also helped us through the city’s permitting process to get the requirements and details done; they were thoughtful and swift in responding to the city’s requests. There were no surprises with the design fees.  In the end, we have a beautiful modern and functional design that fits in well with the neighborhood. Over 65% of the existing home will be remodeled and an additional 30% new living space will be added. My wife and I were very pleased with the outcome and even more excited to see this design come to life for our family. We even have a Phase II project lined up with Yenny and his team to build out the outdoor living space. We would gladly recommend YNG Architects to our friends and family. Now, this also means the construction project will be large and complex and require an experienced general contractor. We did interview other builders but chose Yenny (via YNG Construction) for similar reasons as the design—experience, pragmatism, and working style. We look forward to this next phase of our home remodel."

"Overall my experience with this company was great! The work that was done was really really good! Our contractor who assisted us was Jose. We added a living space and master bedroom to our home. The additions done look as if they were part of my house this whole time. Honestly it looks way better than I expected. The only reason I rated the company a 4.5 was because there was always some kind of miscommunication between our contractor and his workers. Don t get me wrong, things were always resolved, Jose was great at that. But my recommendation to is to make sure communication is #1. That way the customer is not confused or left wondering what will happen next. There was an issue with his floor guy though, he was rude and unprofessional. BUT the reason I am mentioning this is not to put down the company but let you know that we expressed concern for this issue and it was resolved professionally by Jose and it never became an issue again. The quality of work was top notch! His workers were all pretty cool guys and we always felt comfortable of who was coming into our home to do the work. I highly recommend this company for your next big project😊👍🏼"

Custom Home Builders FAQs, answered by experts

Modular homes last an average of between 50 and 75 years, and high-quality modular homes can last for 100 years with proper maintenance. For comparison, a standard home lasts 50 to 100 years and can push to 150 or longer with good maintenance. Modular homes provide better long-term value in that they are significantly more affordable and can last almost as long, but some buyers are wary of modular home longevity, so the actual value if you sell could be lower.

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.

Yes, professionals offer mantel and surround customization for aesthetic appeal.

Modular homes are cost-effective, energy-efficient, and faster to build than traditional homes. They also offer customizable designs.

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
