"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."

"I was very impressed with Sentri Homes - their customer service was excellent. They sent a subcontractor to install some vinyl laminate in my bathroom and he ended up getting glue all over the carpet in our bedroom. The sub ended up ghosting both me and Sentri, leaving me stuck with a ruined carpet. Sentri stuck with me for over a month to get the carpet replaced with the identical original and to get the vinyl job 100% completed. The carpet was a Home Depot exclusive and Sentri handled everything with them. I will be using Sentri for a much bigger renovation I have coming up soon, because I know that they will make sure everything gets done right no matter what problems come up. The vinyl looks great too."

"Chris with Bizzy Beaver has been AMAZING. We have hired them for 3 separate projects in the last year after purchasing our first home. We initially used them when we adopted a rescue dog and needed to get a 6ft privacy fence built ASAP. Chris and his team completed this quickly and did a great job. We then had Chris build custom cabinet doors, drawer boxes, and drawer fronts to update our kitchen in time for an event at our house! He made sure to complete the project on time, and the kitchen looks amazing and like a totally new kitchen! Chris also helped represent us to our insurance company while helping us file our claim after a major hail storm. Tim and Chris explained everything in depth and made the process as easy as possible for us. They met with the insurance adjuster to ensure all damages were assessed correctly, which was a huge help since we are first time homeowners and had never had to do that before. Bizzy Beaver is always reliable, on time, personable, and makes sure everything is completed correctly. Chris and his team are so easy to work with - I would definitely recommend using them for any of your home improvement projects!!"

Custom Home Builders questions, answered by experts

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

It’s typically more cost-effective to move a building along with its accessories than to demolish and rebuild it from scratch. However, that’s only if you can move the accessories without damaging them. However, if you plan to demolish the accessories anyway, it is advisable to do so before the move to save costs.

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.

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.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits.
