"I hired Victor to build a new house to specification and it came out great. The finishes were high quality and working with him was a breeze. I appreciated how organized he was and how he kept the project on schedule. Would very much recommend him to others and use him again."

"AJF Construction did an excellent job. The two people who worked on our project, one of whom is the owner, were professional, honest, easy to work with, and very meticulous in the quality of their work. One major part of the project required the disassembly, cleaning, repair and replacement of floor-to-ceiling screens in a screened-in porch. This was custom-built, so each panel only fit its original location, and disassembly was complicated by some settling of the porch. They did a beautiful job on it, and did not paint over any hardware, so the next time it needs fixing it will be easy to do so. The quotes were detailed and there were no cost overruns. They did a great job on everything, kept us informed as the work progressed, and left the site cleaner than it was when they started. We were very impressed. We recently hired them again to replace a slide glass door. They did a wonderful job on that too."

"This was a full remodel. The work went very smoothly, it took about 2 and 1/2 weeks. The guys were organized and clean. They were on time every morning and were very easy to talk to. They know what they are doing and often would offer advice on project or choice of materials. The tile work is excellent. Would defnitely hire them again. Very good work and more affordable than other bids we received."

"When I call him, at the first time. I did have no idea how complex was build a play room in the basement  . But Claudio came over and explain me, what should i do, he brought some  ideas from his past experience. Not only that his entire  team were very meticulous on details, He is very honest, performed the job nice and clean. The quality of the finish work was excellent, and the job finish on time. I'am planning to hire him again.

Custom Home Builders FAQs, answered by experts

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

It’s typically more cost-effective to move a building along with its accessories than to demolish and rebuild it from scratch. However, that’s only if you can move the accessories without damaging them. However, if you plan to demolish the accessories anyway, it is advisable to do so before the move to save costs.

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.
