"I needed a custom porch built on my 1940s home. John and his team handled the project with creativity and sensitivity to the unique situation. Drawings and permits handled quickly, they even utilized bricks I had stored and extended our porch space to match the existing footprint"

"Team was fabulous to work with, hands down. My vision was to add more living space without adding square footage. Expert Home Builders made it happen. Walls were moved, doors rearranged, pocket door installed, custom shelving, new kitchen with extra seating, and new bathrooms came to life. I felt I was part of the Expert team. My vision and their high standards created my perfect place."

"It went great. We have remodeled three houses and always had bad experiences whenever we used a contractor. Kenny, owner of KTD Construction, is hands down the best contractor. His pricing is fair and often less than other competitors. He is always in contact with you throughout the project, which is rare. He is an exquisite carpenter and framer and his crew are all courteous and professional. He is a fast worker, gets the job done right and even hauls all project debris and cleans up after with great attention to customer satisfaction. Our neighbors even commented that it’s hard to find a good contractor and one that works weekends no less. Kenny will also help find sub contractors for plumbing, electrical, drywall, and if they don’t follow through Kenny will see to it that the job gets done on time and to the highest standards. If you are lucky enough to have Kenny on your job you will be a happy homeowner just like us."

"Spectrum One is our choice over and over again for renovating our home, which was built in the 1960s. Dennis comes out and looks at the scope of the project and gets back to you in a timely manner with an incredibly detailed and professional proposal. He takes into account your vision for the home and offers suggestions for improving the project or explains how the team can make that vision come to life. The project managers who oversee the project from start to finish have been diligent, respectful and ensure that the work being done is of the highest standards. They are on-site every day with a whole team working to get the job done as beautifully and as quickly as possible. The attention to detail from the whole group is what I most appreciate. We have used them for whole-home flooring (removal, installation and baseboards), recessed lighting, countertops, backsplash and would trust them with any project. We recently completed a third project with Spectrum One that included widening doorways, redoing an outdated fireplace hearth, and remodeling two bathrooms. Everyone at Spectrum One is quick to respond, honest, creative, and fun to be around. We love them and highly recommend to anyone looking to do a renovation, repair, or build!"

Custom Home Builders FAQs, answered by experts

Construction typically takes 3-6 months, including site preparation and assembly.

One of the best ways to negotiate with a homebuilder is to forgo price reductions. Instead, negotiate over upgrades and incentives, as many builders are more willing to go down that road than to decrease their own fee. Even if they were willing to take a cut, a reputable homebuilder often knows their worth, so a willingness to negotiate could be a red flag. Beyond that, builders are typically willing to negotiate closing costs instead of offering a discount on the base price.

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.

Yes, modular homes offer a wide range of customization options for layout, finishes, and features.

Modular homes last an average of between 50 and 75 years, and high-quality modular homes can last for 100 years with proper maintenance. For comparison, a standard home lasts 50 to 100 years and can push to 150 or longer with good maintenance. Modular homes provide better long-term value in that they are significantly more affordable and can last almost as long, but some buyers are wary of modular home longevity, so the actual value if you sell could be lower.
