"My wife and I decided to replace our dilapidated one-car garage with a modern two-car garage. We chose to work with Coach House Garages and could not be happier with our garage and our customer service experience! Having never been involved in a construction project before, the idea of building a new garage was intimidating. We found Coach House Garages here on Angie’s List and contacted them to get a little information. We soon met with Jeff Grummer and after that meeting, we knew we found our builder. We could not have asked for a better partner to work with than Jeff. He was extremely knowledgable, accessible, never pushy and was quite patient (as we had a lot of questions and no understanding of process or timelines). Jeff guided us through the inevitable ebbs and flows, from variances and permits to tear down and construction. When we hit a couple challenges, Jeff helped us navigate the issues and keep the job on track. We were...and are...impressed with the quality of our new garage and the professionalism of Jeff and the entire Coach House Garage team. We would highly recommend them to anyone considering building a new garage."

"Mr. Handyman was wonderful! Not only was the clearing done perfectly and safely, but under the time quoted. Without Mr. Handyman, I could not have made it out of my home for days! I am not looking forward to another storm, but I feel a lot safer that I have someone to help me. I have had terrible experiences with contractors in the past, and I won’t hesitate to call Mr. Handyman."

"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."

Barndominium Builders questions, answered by experts

A simple A-frame chicken coop can take as little as three hours to build, but a more substantial all-in-one coop to house a large flock can take four or five days to build. Consult a local handyperson or custom coop builder for a time estimate based on the specific details of your project.

The time it takes to build a shed heavily depends on the type of shed you buy. A prefab shed can be built in 4 to 8 hours, while a custom shed will be built off-site over the span of 2 to 5 days. It then takes a few hours, depending on the location, to move the finished shed to its final location.

Choose a barn door with an extra two to three inches on either side of the frame. The width of the barn door will depend on the type and placement of your track, but in most cases, an additional inch or two will do the trick.

Building a tiny house is the least complicated way to build, especially if you’re tackling the project as a DIY. The smaller size means less complex plans, more straightforward utility installation, and fewer ways to make costly errors. Tiny homes still need to conform to building codes and often have other applicable regulations, so be sure to get the proper permits and confirm your build is by the book.

It is almost always more affordable to buy an existing home than to build a new one. Building a home involves numerous costs, including labor, permits, inspections, utility hookups, and brand-new materials, finishes, and appliances. Additionally, new construction loans can have higher interest rates than traditional mortgages, and property taxes on new homes are often higher, increasing long-term costs. An exception is a DIY house build, which can be cheaper than buying an existing home if you do the labor yourself. While building is generally more expensive, a new custom home offers complete control over the layout and design. Furthermore, new construction is typically worth more than a comparable pre-owned home and may provide a better return on investment if sold quickly.
