"Terbrock's team showed up on time and did the work professionally and carefully -- like it was their own personal home improvement project. At the end of the day, Tom Terbrock himself showed up to make sure everything went well. The price for the work, including removal of existing fixtures, installation, and clean-up, was more than reasonable."

"Sentri Homes provided the most professional flooring service I’ve ever had. The LVP installation turned out absolutely beautiful, and I was amazed at how quickly everything was completed without sacrificing quality. The crew was fast, accurate, and extremely detail-oriented from start to finish. Everything was installed cleanly, precisely, and with real craftsmanship. The entire process was smooth, efficient, and far beyond what I expected. I would absolutely recommend Sentri Homes to anyone needing flooring installed."

"I had some loose metal that was very dangerous if it had broken off. Mr Freeman was near by and was able to come reattach the metal. It was really cold but that didn't stop him from reattaching the loose portions. I was really grateful for the emergency work."

Custom Home Builders questions, answered by experts

Historically, Tudor homes originally stemmed from the 15th and 16th centuries, while Victorians appeared during Queen Victoria's reign in the 19th century. The design and structural differences are significant as well. The many types of Victorian architecture—such as Italianate architecture—typically feature ornate trim, wood siding, wraparound porches, and tall towers on top, such as belvederes. On the other hand, Tudor-style homes feature white stucco exteriors with exposed wooden rafters marking the house frame both inside and out.

Green homes are often more expensive to build, averaging around $200 per square foot compared to the $150 per square foot you’d spend to build a standard home. However, green homes can save you money on your utility bills by consuming less energy or creating energy using solar panels or wind turbines on-site. They’re more expensive to build, but they often end up costing less in the long run.

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

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.

Building a house without blueprints is not advised. It will prevent you from obtaining necessary building permits and meeting building codes and is likely to result in shoddy construction and unsafe living conditions. Detailed blueprints ensure that a house is built to exact specifications and is constructed safely and structurally stable.
