"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."

"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

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.

A construction-to-permanent loan is the most common type of mortgage used to finance a house teardown and rebuild. These loans include financing for construction costs and convert to a long-term mortgage once construction is complete. Check the terms of the loan closely before beginning work—there are often restrictions requiring you to use licensed contractors for all work.

An A-frame home can be cheaper to build than a traditional house, but that is not always a given. Prices can be fairly similar in some cases, depending on the location, design, and necessary site preparation. Costs for an A-frame typically run between $100 to $200 per square foot, which is comparable to the cost of a traditional home. The cost of an A-frame can come in under those numbers if you opt for a prefabricated kit.

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 carriage house is a freestanding building, while a townhouse is connected to other units. A townhouse is a full single-family home and typically shares a parcel of land with other connected homes. A carriage house is rarely used as the sole single-family home on a property and is most often an additional building sharing property with a traditional single-family home.
