Customers say: True professional

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"I hired Adelbin Construction for an extension on my home to create and add extra space in my family home. They did a fantastic job, on schedule and was able to come in under budget. They took care of everything from sourcing materials that I had requested to taking care of all permits with the town. 10/10 service. I will most definitely be using Adelbin in the future."

"Classic Construction Inc. is an impressive company to work with. They were always punctual, extremely professional with quality workmanship in every aspect of the roof replacement of my home, to the point of my again contracting Classic Construction Inc. to also upgrade my kitchen. I am very pleased with the outcome. They can take great pride in their professionalism and quality of their workmanship.  
  I have since recommended Classic Construction to many of my friends, all of whom are also extremely pleased with their professionalism, pricing and workmanship .

"Romeo performed an emergency roof repair and dealt with the problem to it's conclusion. He is a man of his word. I subsequently hired him to do brickwork on my home. Both jobs were done professionally to my satisfaction. I recommend Romeo."

"Boulevard Planning did a total remodel of our home. We had a cape and removed the entire second floor and built an full third floor attic. Thanks to John, we some how were even able to live in the house (not ideal) through the entire construction. Could not have asked things to go as smoothly as they did. John is a stand up guy and really went above and beyond. To be expected a few bumps along the way that were immediately taken care of. Cannot tell you the number of complements we get, more importantly it is awesome to be living in the new house. Unbelievably, John stuck 100% to the original budget. We did exceed budget with extras, mostly on the first floor. All of the extras were our own doing. With any contractor, stay on top of the work they are doing in order to be sure it is up to your liking. I would hire Boulevard Planning to do it all over again."

Custom Home Builders FAQs, answered by experts

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

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.

Modular homes are a type of prefab home. Specifically, manufacturers first build modular homes in sections and then deliver them to the job site. The modules, or sections, are usually at least 70% finished before they arrive on your property.

In comparison, prefab homes arrive in panels or segments, and workers assemble them on-site. Generally speaking, modular homes tend to be more durable, and their consistent construction standards may mean you’ll have an easier time getting conventional home loans.

Modular homes are cost-effective, energy-efficient, and faster to build than traditional homes. They also offer customizable designs.

A green home is one that focuses on conservation, with the goal often being net-zero carbon emissions and self-sustainability. It will often include some kind of self-generation equipment, like solar panels or a small wind turbine, high-efficiency electrical components and mechanicals, and high-quality insulation and air sealing to reduce the loss of conditioned air. Many green homes also include xeriscaping or rainwater collection to cut down on drainage and water consumption.
