Our Mission

We at J. Flannery Contracting, Inc. are committed to utilizing our 30 plus years of experience and expertise in the construction industry to provide our customers with the highest quality and workmanship possible at a fair and reasonable rate.

We fully recognize that our greatest assets are our customers and our employees. With this in mind, our goal is to complete every project in a prompt, clean, safe, and professional manner.

The principles of honesty, integrity, and quality are the cornerstone of our business and we seek to earn the trust and confidence of every customer, and serve them in such a way that they would gladly do business with us again, as well as recommend us to others.


Job safety is our number one priority, especially when working off ladders and on roofs. We require our workers to wear safety harnesses and be tethered to a roof anchor while working on sloped roofs.

It is in the best interest of the company, employees, and customers that safety precautions are taken seriously. All ladders are in good working condition and are properly rated for the type of work being performed. Also, while using them, the ladders are properly secured to prevent falling.

J. Flannery Contracting, Inc. carries full liability and workman's compensation insurance, for the protection of our employees, subcontractors, visitors, and clients.

Customer Support

We take pride in our work, use all of the best parts, and hire seasoned professionals, all to ensure that each job is done perfectly. Some times, though, due to extreme weather conditions, time, or other factors some thing might come amiss. Taking that in consideration, it is our promise to honor a warranty for all our work. Defects in the products used are covered by the manufacturer's warrant as well. Any defects in workmanship are covered under J. Flannery Contracting's own warranty.
