"It was great to work with Icon Builders to building our dream home. They went out of their way to accommodate the completion of our home build in time for school. Their response times are great and the staff is truly personable. It was great working with Jenna, Natalia, Joe, Scott, Shawna and Charlie. I will recommend Icon to anyone looking to build a custom home."

Customers say: Super punctual

"I can't say enough about A P Builders and how absolutely wonderful they have been from start to finish. We completely gutted and remodeled our home and Angelo was upfront, honest, timely, and everything that was contracted was done to perfection. We had crew there every day from start to finish. He started on time and finished on time. Any change orders were handled professionally and solutions were found for any unforeseen challenges due to the age of my home. I highly recommend AP Builders for any of your home improvement needs."

"I've been working with John and his sub contractors on this property since August of 2013, and they have been patient, responsive, and transparent throughout, especially appreciated when my property insurance had to get involved and they worked with them to get them details, quotes, and insight, as well as being a much-needed professional advocate that I never would have been able to accomplish on my own. I have no doubt that John's professionalism helped speed the process along.
When I realized I would have to switch contractors from my first GC, out of everyone I called, John was the only one who brought someone with him for a second opinion on his assumptions, and even sent additional subs out to ensure the accuracy of the quote. I have had nothing but great experiences with him and everyone he works with since.

"This is my second project with Fil and Thor Build. The idea to construct a mezzanine was something that I had envisioned when I first saw my condo. I showed Fil my ideas on paper along with photos of how I wanted everything to look. Fil ran with it and brought it to fruition. Everything turned out even better than how I had envisioned. During the project, I requested some modifications which Fil gladly accommodated; he even created a custom door for me that is absolutely stunning - the quality work of artisans! To top it all off, this project was completed while I was 600 miles away. I had to rely strictly on photos and good communication. I had tons of questions during the construction phase and I'm sure I must've drove Fil crazy at times. However he was always professional and answered all of my questions and addressed any concerns that I had. I can't say enough about Thor Build, they are my go-to contractor and I am so fortunate to have found them."

"I loved making one phone call and having them take care of the rest!! I had my gutters, siding, and roof all replaced hassle free. I was able to pick out what I wanted from the comfort of my home. Each crew came out and finished each job in 1 day! They cleaned up very well. Which was awesome since I have 4 small kids and 2 dogs who live outside! The owners actually came out as the house was being worked on and made sure everything was going as planned!"

Custom Home Builders FAQs, answered by experts

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.

On average, the cost of a home builder is about $150 per square foot, but that price can range from around $100 to $400 per square foot or more. That puts the typical price range of a standard, 2,000-square-foot house between $200,000 and $800,000. Some factors that affect the price of hiring a home builder include the following:

  • Location of your home and the living cost in the area

  • Type of foundation and framing you choose

  • Quality of the building materials

  • Footprint and layout of the house

  • Number of stories

  • Builder’s experience

Check reviews, compare quotes, and verify licensing. Ensure the builder has experience with modular construction.

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?

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.
