"Everything went great from start to finish - I'm very pleased with the experience and their work! I wanted a general contractor type of company that could come in and just take my hand-drawn vision on graph paper to a fully completed project, and that's exactly what they did! I wanted to not have to worry about coordinating different contractors to do pieces of the work and have to babysit the process, worry about workers not showing up and throwing off the rest of the schedule, and have things drawn out over months and months, like we had done upstairs. My husband and I knew the kind of company we wanted would come with a higher price tag than patchwork contractors, which it did, but it was well worth it for the headaches and time they saved me!! They were always on time, highly communicative (which is very much appreciative and not always present in the construction business), and very pleasant to work with! They didn't even blast music like most construction crews, which made for the best possible experience having others in your home every day for several weeks. Even minor sticking points we ran into (couple of wrong parts ordered, door & schedule changes, etc.) were no big deal to hash out. Everyone always made time and was patient with answering my questions and addressing requests or concerns, which was awesome. Even when I was laid off after signing the contract and needed to find more work in a tough COVID-19 market so needed to delay the start date, Tom worked with me. They made sure we're 100% satisfied, which we very much are! The quality of work is great, and everything looks amazing as you can see in the photos below!"

"We love our new shed! We hired Tittel Construction to build a custom shed on the site of our previous shed. The concrete pad was there already but has a definite slope from a previous tree growing too close. Connor was able to not only build a great shed, but also make it level on a sloped foundation! He was very patient and helped me design, through Pinterest pics and my rough drawings, the perfect shed including 10 reclaimed windows. I’d highly recommend Tittel Construction."

"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

One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.

Ultimately, a work warranty is only as reliable as the contractor you’ve hired. That’s why trust and reputation are such important factors, in addition to having a solid contract and confirming appropriate licensing, insurance, and bonding. When looking for a contractor, it’s a good idea to read online reviews and ratings to see what kind of experience past customers have had. Issues with your contractor can make for an unsatisfying renovation process, but a reliable contractor can make the process go as smoothly as possible.

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.

Yes, a home builder or contractor should have the proper licensing and insurance. Licensing requirements vary by state and municipality, but most states mandate that a builder holds at least a general contractor’s license. For specialized work such as plumbing, electrical, roofing, or sewage systems, individual licenses may be required, in which case the builder may subcontract the work. You can use Angi’s state licensing tool to review your local guidelines and confirm a builder's credentials. As you browse professionals, you can also look for the “Angi Certified” badge. This indicates the business meets our certification standards, which include passing a criminal background check, holding applicable state and local licenses, and maintaining an average rating of 3.0 or better.

Check reviews, compare quotes, and verify licensing. Ensure the builder has experience with modular construction.
