At Grennan Construction we believe in providing consumers with the information, skills, and abilities needed to become more informed homeowners.
“Did a great job helping devise solutions for problems with a 98-year-old historic home. Carpentry & paint skills excellent! Good communicators. Always knew what to expect.”
“I had a masonry job on my late 1920s home and Grennan Construction did an absolutely outstanding job. I would definitely use them again in the future!”
