"We recently had a fantastic experience with Jim / OHI. They built us a beautiful new deck and installed a patio door, and the workmanship was excellent from start to finish. When we ran into unexpected building and zoning issues with the town, they were incredibly flexible and worked with us to adjust the project. Instead of the larger deck we originally planned, they created a stunning patio in that space, which turned out even better than we imagined. The crew was professional, reliable, and detail-oriented, and the results have transformed our backyard. We couldn’t be happier and highly recommend OHI to anyone considering a deck or patio project."

"We were very pleased with the job performed. Helio's team expanded and renovated our small master bathroom. We took out a large closet and converted it into our shower. Once started, they worked quickly and efficiently. We did have a few small hiccups, namely using our garage to cut tiles and mix thinset, which created an exorbitant amount of dust coating my tools, bikes, and anything else that was stored in the garage. We also had an issue with the cleanliness of the home after some of the workers left, however, after we brought it to Helio's attention, he made sure to tell the team to do a better job moving forward. Contract was a little confusing, so I would encourage many questions to clarify things ahead of time such as timeline for selecting certain items, confirming when the next payments are due etc. All in all, we're pleased with the project and how it turned out."

"We reached out to Brother's as a former customer from 40 years ago. They came to my home, spent over an hour with us to listen to our needs, provide us with samples, and discuss options. Brothers resided our new home, replaced the roof, gutters, soffits, flashing of the chimney, replaced a new window, and pitched part of one of our chimney's. The work was impeccable. The owner was available for questions, the foreman was approachable, the workers kept the property neat, and our home looks brand new on the exterior. Brothers Alumnium didn't disappoint 40 years ago, and they didn't disappoint now. Highly recommend. 5 Stars!!!"

Custom Home Builders questions, answered by experts

Yes, a home builder should have a builder’s license and insurance. States have different requirements for builder’s licensing and certifications. Be sure to check our state licensing tool to review your local home builder licensing guidelines.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.

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.

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.

A construction-to-permanent loan is the most common type of mortgage used to finance a house teardown and rebuild. These loans include financing for construction costs and convert to a long-term mortgage once construction is complete. Check the terms of the loan closely before beginning work—there are often restrictions requiring you to use licensed contractors for all work.
