"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."

"It went very well! Chuck was an absolute gem, was thorough, kind, and did an amazing job with the work he does. He doesn't leave any detail untouched and is willing to go above and beyond for the customer! Our tub ended up leaking and he came back, fixed the issue above what we asked, replaced the ceiling tile in the floor below where water had damaged it free of cost(even though it wasn't his fault it leaked), and always made sure we liked the final outcome on whatever he had built that day. I felt a man who truly CARES about his job and work place which is hard to come by now days! Definitely would hire again! ?"

Custom Home Builders questions, answered by experts

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.

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.

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.

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.
