"T&K Builders LLC, Terry and his Team were the ultimate professional. What was promised was delivered and more. Terry and his Team explained all the steps being performed. There was no surprise when it came to the invoice. I would hire T&K Builders LLC, Terry and his Team again and again for any of my home improvement projects - large or small."

"We had VM contracting do the roof on our home a couple years ago and the work was stellar! When we needed the windows replaced we had Mr. Vinney come back for this job. 10 windows and a large bay window. The work, once again, was very well done! Very competitive pricing and on time completion. We will use them in the next year or so when we we do the siding our home! Highly recommended!"

"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

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

If you want to make your home eco-friendly, enjoy low maintenance, and love the fact that its looks will take people’s breath away (and not because they were trying to blow your house down), then a modern brick home is right for you. You can hire a mason to get the building process started for your brick home.

But if you’re not fond of the color and don’t want to deal with the process of repointing or other repairs, consider going with vinyl or wood. These materials offer a lower cost. While they tend to require more maintenance, they don’t cost nearly the same as exterior brick house repair.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits. 

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.

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?
