"After looking for 1 year for a contractor, we looked at Angi. We were connected with Antonio of A&M General Construction, and we walked around the house explaining what we wanted. As we explained our plans, he asked questions but never said we won't be able to do that or change our minds to do something we didn't want. We had them remove four windows and replace 3 of them them were able to get exactly the windows we wanted. Took out two walls and opened up the room. Opened a walkway into the bathroom. Moved an intake vent. Painted, layed tile, converted bathtub into shower. We were very happy with the results. My wife loves her new master bedroom."

"The work went very well, my wife and I were pleased with the prompt professional service. The price was affordable and the work was great, once finished he cleaned after himself and made sure we were satisfied. I would definitely refer this company to anyone I know who needs any home repair work. Chris met our expectations and beyond with the affordable price and high quality service along with a time frame."

Custom Home Builders FAQs, 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.

Building a new home can be more expensive than buying an existing one, depending on the housing market in your area. Many homeowners still find that building a new house is worth the investment as they can choose the exact layout they want, as well as to choose their own floors, wall coverings, appliances, and finishes. If you live close enough to the build site, you can also stop by to check on the builder’s progress, which can provide some peace of mind that the project is worth it.

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

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.

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.
