"An amazing experience! I was constantly involved with the decisions being made and was always comfortable with the company itself. I was continuously updated on due dates, payments needed and actuality of each situation. Amazing communication between each and every contractor. I loved how my house looked by the end of it and would highly recommend Strategic Operational to anyone!"

"I have not completed this project yet. I am still in the beginning stages but so far Hudson valley Home source has been wonderful. Brian Hitt is very knowledgeable and competent in everything he does. I expect everything to be complete around November or December. Feel free to contact me then and I will be more than happy to give my opinion."

"We hire HM Construction to remodel our very old and outdated kitchen and adjoining bathroom. HM Construction previously worked on our den, and it was a no-brainer to go with them again for the next big project. HM's quote was fair and there were no hidden costs along the way. Helio is incredibly responsive and is always able to fairly address any issues that may arise during construction. HM got us in touch with a designer who came up with a floor plan that we never would have thought of otherwise. Our kitchen was a huge project and the results are unbelievable. The workmanship is top notch and we could not be happier. HM is trustworthy, fair, and does excellent work. We could not more highly recommend HM Construction for any home project."

"My wife and I DO NOT use anyone who is not on Angie's List so we understand the importance of having accurate, fair reviews. We found Cary on Angie's List with overall great feedback on jobs he had done so we called him in for an estimate. Despite being very busy, he made the time to come over on a Saturday morning. He had previously dropped by and assessed the damage from the outside but needed to see it from the inside to ensure he could judge it accurately. After 15 minutes, our fears were realized and he said he would need to remove the cedar impression siding and remove the roof and replace it with a different system because the pitch wasn't steep enough. 
Within 48 hours, he provided a quote for his crew to come out and get the work done in a single day which was completely reasonable. He completed the work (guaranteed) as promised and left the site immaculate. He took pictures of the issue, of job progress and of the completed job. He mentioned he went around and filled some other issues he noticed while he was waiting for his crew to wrap up, no charge at all. He then discounted the quoted, agreed price 5% for angie's list deal I wasn't even aware of. Have you ever heard of a contractor accept less than an agreed price? Me neither.
Angie's List is a great resource for people to share experiences. I think the contractors who are honest and reasonable should be applauded too. We have been on the receiving end of some really lousy service so this was a new experience having someone do what they promised to do. Cary and his crew are the best in Monmouth County. We already have him pricing out finishing a storage space and will use him to build our deck in the spring. I cannot recommend Cary enough and you can reach me through Cary if you'd like to see his work firsthand.

Home Building FAQs, answered by experts

How long it takes to build a custom home or rebuild a home after a disaster varies depending on many factors, but averages between seven and 14 months. Smaller homes or homes that don’t need a re-poured foundation may take less time to build than larger homes or homes without an existing foundation. Material availability, contractor schedules, and permit and inspection timelines can all affect how long your house takes to build.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

Custom homes can take an average of 18 months to build, mainly due to the lengthy design process, and most projects take somewhere between 12 and 24 months. When you work with the right custom home builders near you, they can help you map the road ahead and understand what can speed up or delay the timeline. Choosing locally available materials, for example, can speed things up without losing that customized touch.

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.
