"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."

"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."

"We actually had 4 major renovations - the basement finished, master bath remodel, kitchen remodel, and garage finished. Started the projects on 6/1/2022 and finished on 7/31/2022 - amazing time frame. Projects flowed smoothly, attention to detail was awesome. All of our questions and concerns were addressed to give us the utmost comfort level to choose Aaron/Clean Edge to handle our remodeling projects. Carmella did an awesome job in keeping us updated on when to expect contractors to be in the home. There is not one thing that I would have changed in what was done, but believe me, we did change things as we moved along in the projects... added a 1/2 bath in the basement and changed the kitchen and basement counter choices. Aaron and crew were amazing to work with. I would highly recommend them and were very happy to work with them."

"

Overall we are very satisfied with the work. It didn't take long for John to review our initial drawings and issue a quote and get the job scheduled. Between the time we scheduled the job and when work actually began we made some changes to the plans and John and his guys were able to accommodate. They also found some relatively shoddy workmanship from the builders of our townhome and did their best to point out areas that needed attention. The initial demo and framing went very well and moved quickly. After demo and framing there were times when communication wasn't the best and there were many days when work wasn't done and we weren't kept up to date on the schedule, which I understand is very typical for this type of job and not unique to John and his guys. I do wish he would have used a different electrician. He was pretty messy and rarely showed up and we still have some minor flickering with the lights in our master bedroom. The finishes are excellent and John's tile work was very good. The custom vanity they built for our master is excellent and it's fits perfectly. The shower glass is just what we wanted. Overall I was vey happy with the outcome despite some minor frustrations with the process. I would definitely call John again for other major jobs.

"We originally hired Peter to do the design only. We selected him over other architects and are pleased with the design. He listened to our ideas and provided very practical solutions and helped us with zoning variances. During the design phase, they added "and Builders" to their services. We selected Idea over a lower bid because of our good experience with Peter. The build is in progress and the sub-contractors are profession and do quality work. I will update this report when the build portion is complete."

"The service was top notch and would definitely use the service again. Contractor was very professional and always honest with the situation. Price was a bit higher than I initially budgeted for but the quality of work more than made up for the higher cost. I was very pleased with the whole job being completed in 3 weeks when it was initially estimated for a 4 week process. Any future home construction jobs in the future, I will immediately call this contractor first.

Custom Home Builders FAQs, answered by experts

It usually takes around four to six months to build and install a modular home, although your timeline could go up to around eight months if there are delays in the manufacturing or permitting process. Heavy site preparation and foundation pouring can extend that timeline if you need them, as can customizations you want for your modular home. Your modular home company should be able to provide an estimate for the construction timeline before you sign any contracts or agree to any work.

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

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.

Modular homes can go up or down in value depending on a few factors. In areas where real estate is appreciating, the value of modular homes is likely to increase, and vice versa. Additionally, the value of modular homes depends partially on the area. In cities where every other home is stick-built, modular homes might be considered a functional obsolescence, in which case they could be less desirable and go down in value. In either case, though, modular homes can still be a good investment, especially since they provide housing at a lower upfront cost.

It is a good idea to check in with your local city and state regulations before committing to building a shipping container home no matter where you live. This concept is pretty new across the country, and many places won’t let you build one.

The International Code Council (ICC) offers guidelines for home builders on the safe use of ISO intermodal shipping containers repurposed as building components, which can be helpful to review when planning or designing a shipping container home.
