Testimonials From our Satisfied Customers

"Grennan Construction did a siding project on my home during the winter of 2018/2019. I selected Grennan over three other competitors. Fred‘s professionalism and honesty, along with his creative input to the project, were determining factors in selecting Grennan Construction. We used a James Hardie product and I could not be happier with the end result. The crew that completed the project was fantastic. They worked through absolutely miserable conditions due to the extreme cold and snow while the project was going on (It was under 20° during most of the project). My home has some tall peaks and interesting angles, and they did an absolutely amazing job. Fred and the crew were also terrific with follow up on any small touchups that needed to be done. Grennan Construction did a terrific job on my project. I recommend them highly without any hesitation should you consider them for siding or any other projects that Grennan does. -Jim Fagan "Replaced my home's siding using Hardie Cement Board. 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." – Jon Rogers
