Q. How long does a project take?


A. We have a very disciplined process and are usually within a couple of days of quoted start time, if weather permits.

We are usually able to coordinate and develop a great strategy for completing every project in a short and timely manner. Tactically, I work to educate my team on every project and my 15 years of experience in this general construction industry translates to professional, timely and competitively priced projects every time.


Q. Do you have the right insurance?


A: Denisco Construction has all the necessary insurance. We’ll be happy to have our insurance agent email, mail or fax our coverage to you before we start your project.


Q. How do we get started?


A. John: These days, like most contractors, I do most of my conversing through cell phone. I am readily available from 7AM to 7PM via cell phone. Text messages and emails can reach me the balance of the day. If you have a house emergency, especially with your roof in the winter after a storm, I will go way out of my way to help you safely get your home under control again.
