"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."

"Cain was friendly, kind, and professional. I had such a small "honey-do" list, but he treated me with as if I had a remodeling contract with him! HBC is providing such a needed service to those of us who need minor repairs done around the house and we can't do them on our own. Now, I know who to call, and that will be HBC!"

Custom Home Builders FAQs, answered by experts

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.

Hiring a reliable home builder is an essential task, but there are a few questions you can ask a potential builder to ensure you they are trustworthy and up to the task:

  • How long do you expect the process to take?

  • Are you fully licensed and insured?

  • How much of the work will you subcontract?

  • Will you pull all of the necessary permits for the job?

  • How long is the builder’s warranty you include with your work?

  • How do you handle resolution for issues I might have with the finished product?

  • How much experience do you have?

Shipping container homes last at least 25 years on average, but they can last even longer with proper maintenance. Since shipping containers are made from metal, they’re quite vulnerable to rust and corrosion. This issue is exacerbated in coastal areas or areas with a lot of precipitation. To extend the life span of your container home, install siding that protects the exterior. 

Handypeople usually don’t hold trade licenses, so they typically aren’t qualified to tackle projects involving installing or making alterations to plumbing or electrical lines. Below are some jobs that a handyperson usually won’t be able to complete:

  • Installing plumbing for a new kitchen or bathroom

  • Replacing plumbing pipes

  • Installing or repairing septic systems

  • Running new electrical wiring

  • Installing a subpanel

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.
