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!"

"Maximo Construction gave us a great bid, has competent and friendly workers, kept to the agreed upon schedule, and turned out exceptional products in our new composite deck and pergola. Maximo engineered the pergola to hold retractable canopy panels. The pergola is extremely sturdy, symmetrical, and aesthetic. His communication was excellent throughout the entire project. I could not recommend him and his company highly enough. I will definitely hire him/them again!"

"Dana was the foreman on a major remodeling project on our property. We added a guest cottage which involved excavating over 100 ft.³ of hillside, foundation, as well as construction. He also remodeled the main house extensively from a concrete pour to new roof, electrical flooring, fine carpentry and everything in between. Throughout the 2- year project, Dana was attentive to detail, honest, mindful of the budget and schedule, and collaborative on creating solutions. He is such a kind hearted person, and was a pleasure to have around the home. I canâ t say enough good things about String Theory Construction!"

Home Building FAQs, answered by experts

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.

How long it takes to build a custom home or rebuild a home after a disaster varies depending on many factors, but averages between seven and 14 months. Smaller homes or homes that don’t need a re-poured foundation may take less time to build than larger homes or homes without an existing foundation. Material availability, contractor schedules, and permit and inspection timelines can all affect how long your house takes to build.

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.

It usually takes around four to six months to build and install a modular home, although your timeline could go up to around eight months if there are delays in the manufacturing or permitting process. Heavy site preparation and foundation pouring can extend that timeline if you need them, as can customizations you want for your modular home. Your modular home company should be able to provide an estimate for the construction timeline before you sign any contracts or agree to any work.
