We were very happy with the work that was done and the professional manner in all that they did, starting with a very detailed estimate and a clean jobsite daily. I would highly recommend them!

We have used Grennan Construction for both our siding and our roof replacement and have had a great experience on both occasions. Their quoting process was very transparent - they answered any questions we had and priced the job fairly. Our project managers were easy to get a hold of and quickly responded to any questions or concerns we had. The work was done quickly and with quality. Our roof needed some major work done, and the crew finished the job in a timely manner and addressed every issue that needed to be fixed. I'd recommend Grennan Construction to anyone (and already have!).
