"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."

"I interviewed six solar companies and got bids from three. Charlie of Landmark construction & energy crew stood out much more above the other companies that I spoke and met with. He is responsive, always returned my calls quickly and he does what he says he is going to do. Charlie came over to my house and met with me before installation, during the installation and after. In addition he worked with his crew at the beginning of installation to make sure everything was perfect with a tricky area of my roofline. Above all of what I wrote above, Charlie and the office staff are very organized people. Charlie was able to provide me with a lot of information about rebates, taxes etc… and Every bit of information I could want related to monitoring my system, working with Landmark construction & energy crew, maximizing the cost benefits, and getting my tax rebate, are all gathered and clearly labelled in a binder. Charlie knew how to explain everything about solar and I could see during our meetings how much patient he have. Charlie didn't have to push anything in order to sell his work to me because his product was the one I wanted, it made sense, and the price was better than others. I can't think of a contractor and I've worked with quite a few once in the past and for this project, I met with several ones as well and Landmark construction & energy crew is more reliable, efficient, and customer-oriented. Thank you, Charlie!"

"We were looking for a contractor to completely remodel our one bedroom condo in San Francisco. We met with few different companies but after meeting with Moses from HomeTech Construction & Design, he gave us great suggestions that showed us his experiences. He was also very clear with the cost and what his included and what is not. They were able to work with our budget as it was very important also they provided 100% financing for no additional cost. They helped us pull all the necessary permits as well as made sure everything is done by legal expectations. Project was finishes at least two weeks earlier then predicted and the apartment rented even before all work was done. We and new tenants were really pleased with the finishes, design and quality of work. We especially really like the bathroom finishes. It was very easy communicate with the designer, office, contractor, and of course Moses, the project manager. Also the communication between the team was very well coordinated. We would definitely recommend HomeTech to everyone looking to remodel their home."

"Dror Postiner and his crew did an amazing job on our kitchen remodel. From the very beginning, Dror's #1 concern is that we as his customers are happy. One of the reasons we decided to go with A2Z is the promptness of Dror's response. General contractors are very busy right now, but I was very impressed by the responsiveness and the reliability of the team. Dror made sure to come with us to the store and give us his professional opinion (which was invaluable) on all of the materials used. Additionally, the team stayed within the timeline of the original quote. They were fair with pricing and the team was so friendly and nice to be around. We are very happy with the end product and this project in general!"

"Just finished a bathroom remodel with OC Builders and had a great experience with them, especially our project manager Evan. While there were slight things that needed to be changed during the project, Evan was always gracious and his team made the changes without hesitation. Great working with Evan and his team = )"

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.

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

Remodeling a house is often less expensive than building a new house. You can expect to pay an average of $100 per square foot when you are remodeling. The cost to build a house averages about $150 per square foot. When remodeling, though, some rooms cost more than $100 per square foot and some cost less. Use a home renovation cost estimator to accurately estimate your remodeling costs.

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

Start by researching local contractors with experience in cottage construction. Ask for references, check licensing and insurance, and review completed projects. Compare multiple bids, making sure each includes the same scope of work. A good contractor will communicate clearly, provide a detailed contract, and ensure all work meets code and safety standards.
