Customers say: True professional

"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."

"We had an addition built into our home to accommodate our growing family. We were a little nervous about having contractors in our home as I was pregnant at the time but the guys from RS Construction could not have been more professional. They always made sure things were kept clean and safe around the house as they worked. They did a beautiful job with the addition and the price was very fair. I highly recommend their services."

I want to give a special shout-out to the construction team because of the attention to detail and care they took with their work. Would definitely work with OZ-ARI again for any future home updates. I couldn't be happier with the results!"

"One of my relatives recommended to me this home remodeling company after he hired them for his house and they were super happy due to the fantastic job that Best Builders did at his home. At my house I wanted a new patio deck built before the summer will start. Sofia from the main office scheduled me an appointment with one of her people and she sent out Zohar, who worked with me step by step through this entire remodeling project. Zohar is a great guy and a professional person! He made sure that everything is being done exactly as it was promised in the design stage AND each change that he wanted to do (in order to make this project better than it should). The new deck including the covers looks fantastic and it came out much better than I imagined. I’m glad to have worked with Best Builders Group!"

Custom Home Builders questions, answered by experts

While some highly experienced homeowners can frame a house independently, it is not advisable. You will need ample carpentry experience, a team of helpers, and professionals to sign off on your work to meet local building codes. For the safest outcome, we recommend buying or building a house with the guidance of professionals.

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?

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

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.

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.
