"I am beyond impressed with the service from So Cal Builders & Design Inc. They listened to my needs, offered creative design solutions, and executed the project flawlessly. Their team is skilled, respectful, and truly cares about customer satisfaction."
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.

"Nathan impressed from the time I first met him. He was far more professional than other contractors in terms of describing how his company works and what I should expect if I worked with him. He also has a nice showroom where you can look a variety of cabinets in different styles and colors as well as countertops. We ended up getting a countertop that he suggested. We would never had picked it on our own but it ended up looking amazing in our kitchen. We had him do a complete remodel of our kitchen and one of our bathrooms. The guys on his crew were always prompt and showed up as scheduled. His foreman was both a good communicator and listener. Whenever we ran into an unexpected issue, they communicated clearly what additional costs would be involved (if any) and how much additional time it might take. The cabinets he installed were custom made but did not cost more than the pre-fab ones you can buy at the large home improvement stores. They are of high quality and well constructed. I actually saw his cabinet guy using a small caliper to make sure the door distances from the cabinets were all even! Lastly...here's something you'll never hear about a contractor...he finished AHEAD of time! Nathan's company are straight shooters and very skilled craftsmen. I would work with them again."

"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."

"After meeting with several contractors, we settled on MVP Builders. They replaced the worn out roof on our home with a beautiful new one! After David showed us a variety of products to choose from, he and MIke made sure the job was completed to our satisfaction. They were very professional and friendly and made sure we were happy with the job... and we are! Thank you MVP Builders!"

Custom Home Builders FAQs, answered by experts

Hiring a reliable home builder is an essential task, but there are a few questions you can ask a potential builder to ensure you they are trustworthy and up to the task:

  • How long do you expect the process to take?

  • Are you fully licensed and insured?

  • How much of the work will you subcontract?

  • Will you pull all of the necessary permits for the job?

  • How long is the builder’s warranty you include with your work?

  • How do you handle resolution for issues I might have with the finished product?

  • How much experience do you have?

The longest part of building a custom home is the design phase. It takes multiple professionals and a ton of work to bring your vision for your dream home to life while sticking to a homebuilding budget and also ensuring everything is built to code. Expect the design phase for a custom home build to take six months to a year.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Craftsman-style homes are predominantly found in the Western United States, specifically in Southern California, where the style originated. Since the climate was mild and there was access to plenty of natural resources, Southern California became a hub for this style at its inception. That being said, if you consult with an architect near you, you can have a Craftsman-style home anywhere.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits.
