"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 a great experience working with CLAH on our bathroom remodel. The team was professional, responsive, and did a great job helping us through the design and construction process. They paid attention to the details, communicated with us throughout the project, and made sure the finished bathroom matched what we were looking for. The quality of the work came out very nice, and we appreciated having one team help coordinate everything from the design decisions to the actual construction. We would definitely recommend CLAH/Custom Home to anyone considering a bathroom remodel or other home renovation."

"I had to have my entire bathroom torn out and replaced with new walls, new enclosure, tub and flooring. I am very happy with the job that Cobar Builders did in my home. They were all very friendly and updated me on their progress and asked me how I liked certain things done...honestly this is the first time I have ever hired a contractor to do work in my home and at first I was very nervous, but all my fears and worries have been allayed by Elvin, the owner, and his crew. Elvin and his team were always up front with me about any additional costs and was very responsive to my calls and texts. I definitely recommend them highly."

Custom Home Builders FAQs, answered by experts

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.

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.

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

Construction typically takes 3-6 months, including site preparation and assembly.

A-frame homes are on the smaller side. While there’s no set square footage amount it has to be, it will usually come in around 1,000 square feet or smaller.
