Customers say: True professional

"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"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!"

"We just finished a large addition we had added to our home. Arthur came to our home for our estimate and gave us all of the information we needed. He really educated us on what goes into an addition. He took care of everything and it went smoothly. We are really satisfied with the results and are so happy we went with Best Builders Group. They were always on time, honest and open to ideas and questions we had. If you are looking for a trustworthy and dedicated company then we recommend Best Builders Group!"

"Landmark Construction provided us with an amazing customer service throughout the process of the remodeling from start to end. Their prices were very competitive. It doesn't get much better than this. We were having foundation work done on my elderly mother's home in LA. We arranged this remotely via a friend that recommended us to Ezra and Charlie. Ezra took time, care, and patience to make sure that the remodeling will be comfortable with the process and to answer each and every one of our questions. This alone makes us recommend them as highly as possible. Customer service of this level is very very rare today. The work that they did was managed by Charlie. Charlie brought his 3 men team and made sure they will do an amazing work and as fast as they could.  I would use this company again without any hesitation. I'd give 6 stars if I could.

Custom Home Builders FAQs, answered by experts

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.

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.

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

The average cost to renovate or remodel a home is $52,300, with most projects ranging from $19,500 to over $88,400. However, costs can vary significantly, from as low as $3,000 for a small project to $170,000 or more for a complete home remodel.

Several factors influence the total price, including:

  • Project Scope and Size: The extent of the renovations, whether it's a single room or the entire house.

  • Location: Geographic location affects labor and material costs.

  • Materials: The quality of materials chosen.

  • Room Type: Kitchen remodels ($14,500 - $70,000+) are generally more expensive than bedroom remodels ($1,500 - $5,500).

  • Other Factors: The time of year, complexity of the work, and any additions or expansions.

On a per-square-foot basis, you can expect to pay between $15 and $60 for standard projects and up to $150 for luxury renovations.

Examples of specific project costs include:

  • Basement remodel: ~$20,200

  • Garage remodel: ~$27,900

  • Loft conversion: ~$20,200

  • Disability accommodation remodel: ~$4,300

  • Major home repairs: ~$11,700

If you are financing the project, note that some loan programs, like the FHA 203(k), may require a minimum project cost (e.g., $5,000) and will necessitate a home appraisal and professional cost estimates. Using a home renovation cost estimator can also help you budget for your project.

A contractor can install your shipping container home in as little as 90 days. This is notably quick compared to a traditional home build, which can take more than a year (providing there aren’t permitting or construction delays that make the wait even longer). For the quickest installation, choose a prefab container home.
