Yes, most major remodeling projects—such as finishing a basement, altering plumbing or electrical, or changing structural walls—require local permits. Fortunately, JC Alvar Construction handles the entire permitting process with your local township to ensure everything is strictly up to code.
The timeline varies depending on the size and complexity of the project, as well as material lead times. Generally, a full kitchen or basement remodel can take anywhere from 4 to 8 weeks once construction begins. We will provide a detailed timeline during your initial consultation.

What Our Clients Say
We’ve earned a 5-star rating on Google Reviews!
John and his crew were a pleasure to work with. Home construction is very stressful but John was always available to answer my phone calls and texts. He validated all of my concerns and followed through until I was satisfied. In addition, he accommodated my very busy schedule.
Excellent work, flexible and professional. Highly recommended.
John is a fantastic contractor. We have been using him for years. He is honest in pricing and is work is great. He specializes in many areas and the outcome is always excellent. He recently remodeled my kitchen and I couldn't be happier. He does work for my family, friends, & clients and everyone always speaks highly of him and his team. If you are looking for a reliable contractor who you can trust, definitely contact his company. Thanks John for everything you do!
John was responsive, and both he and his team were professional and neat. John also coordinated with my insurance adjuster, supplying a detailed estimate and pictures. He made an unpleasant situation more bearable!
I had damage to my house when a try fell through the roof. Nearly EVERY aspect of fixing this problem was a complete disaster. Insurance was a disaster, contractors were a disaster, and I had a roofer not return my calls for over a month while a tarp was the only thing keeping water from flooding my house. Finally, John came to the house. Everything was done perfectly and professionally. I am not somebody to typically write reviews, but this was warranted. Highly recommend.
Excellent Work.
Don’t wait any longer to build the space you’ve always wanted. Trust the local experts who have been serving New Jersey homeowners for decades.
