We bought a house and found a leak in the kitchen roof. The leak had caused extensive damage and required a complete renovation. After we got several quotes, we chose Mark Jackson because of his professionalism and honesty. And we didn't regret it. His crew did excellent work, were courteous, and had asked for a list of "special requests" such as cleaning up after every work day, making a temporary door to close off the construction from the rest of the house. If there were any issues he provided his personal cell phone, and was very punctual with answering calls. After the work was done, he even offered to come back to make any touch ups if required, and get a Christmas card from him every where. His dedication to Renomark which is an organization that urges honesty in contractor work is also admirable. I would not hesitate to hire him again.
