"I called the company to have them come and look at some shingles that were not laying correctly.  Prior to their arrival, my daughter backed one of our vehicles into the side of the garage while pulling out, bending the track for the garage door and damaging the side of the garage (broke the 2x4, split the sheeting, etc.).  Mike came out on a holiday because I am in the process of selling my home and needed to have the repairs made ASAP.  He completed not only the roof repair, but replaced the side of the garage and straightened the garage door track.,  And, he cleaned up the garage when he was done.  This company has been extremely responsive and Mike genuinely cares about his customers.  He is friendly and caring and has been a pleasure to work with.  Because of him, I think my house is sold and the family buying it is happy with the repairs completed."

"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."

Home Building FAQs, answered by experts

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

Modular homes are cost-effective, energy-efficient, and faster to build than traditional homes. They also offer customizable designs.

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.

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.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.
