"My only complaint is that The customer service wasnâ t the most warm/ welcoming, but they definitely were nice! Joshua even answered phone calls when he was out of the office which I appreciated. We have been having septic smells in our house for six months and He was not only very knowledgeable, but he found the source of the problem. Even though we only hired him for an inspection, he offered to fix the problem too. (We ended up fixing it ourselves)"

"The technician did an excellent job. It did take a while to get the repair finished, but that was due to Bertazzoni delivering the parts. I have had multiple problems with this particular appliance. My range now works better than it did when new, but I have a feeling that even if I have continuing problems with it, American Home Shield will just repair rather than replace due to the cost of the range. By the way, I'm not exactly sure of the date of the repair."

Home Building FAQs, 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.

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.

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

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.
