"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

In most cases, you should get an architect before you hire a builder. An architect will be the one to draw up formal plans for your project, including guidelines and even material lists for your builder to follow during construction. Many architects can even help you find builders, choose one for your project, and negotiate prices. Some are also willing to act as project managers throughout the process, working closely with a builder from start to finish.

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Yes, professionals offer mantel and surround customization for aesthetic appeal.

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.
