"I had used Grennan several years ago to re-shingle my roof. They did a great job then at a great price, so when we decided to redo our siding, Grennan was one of the 3 companies we called.
Fred Grennan came out, discussed the product, the price, his contract, and his and our expectations. When he quoted his price, we immediately agreed on a deal.
I am so glad we had Grennan do this job. His crew was outstanding, organized, efficient and thoroughly professional. They completed the job as agreed, and took care of some modifications that came up with no additional charge.
Dealing with Fred Grennan was a pleasure. His word is his bond and his aim to please is undeniable. We will definitely call upon him and his company for future needs."
