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!).

Grennan did two projects for me within the last year – the first an exterior siding and trim project and the second a complete tear out and replacement of a tile shower that was improperly installed by another contractor ~5 years ago. In both cases communication was good and Grennan did excellent work, and although every home improvement project is expensive these days, I felt their prices were fair. We’ll definitely reach out to Grennan again the next time we have home improvement needs!

My experience with Grennan Construction has been nothing but positive. I have recently had a new roof and gutters installed and chimney caps repaired. All of the employees that I have dealt with are courteous and willing to help. They finished my jobs in a timely manner. They even helped me repair a gutter that blew off of my mother in laws house. I would highly recommend!

I will happily update if gutters get fixed. Installed soffits incorrectly, would have caused mold in attic and voided my roof warranty had we not discovered in time and got Grennan to correct.A year later, found gutters leaking water into my porch light, overflowing the gutters digging trenches in ground, and water getting behind gutter since they installed gutters on top of drip shield. After months of asking, they finally sent a guy to fix only 1 side of gutters in Nov 2023. Said they'd come back and finish the repairs spring 2024. Since Nov 22, sent many dozens of calls, texts, and some emails requesting repairs, Fred first said fault was gutter guards we installed, so we removed them. Then said gutters were dirty, we had them professionally cleaned. Then need more pictures, we sent them. Then told gutter crew needs to realign the gutters, crew never shows, then talk to project guy, who then says reply Fred email. Fred now is saying need to clean gutters 3x a year and get gutter guards. Just not fixing what I've been told is wrong with their work.Can anyone recommend a good company who can repair my gutters before they rot out my wood behind the trim? Crazy thing, should not be a huge job for them to finish the repairs they started, but after fighting them for going on 2 years to get this done, it might be easier to hire another company to fix and sue them for the charges plus court costs.Sad because i hired them because Mike gave a great quote and promised a 10 year warranty on their work. From my experience they perform shoddy work and then try to wear you down rather than fix their mistakes.

I'm glad we went with Grennan for our home's siding - changing from wood (T1-11) to vinyl. A siding project can cost ~10% of your home's value, and that's a significant investment for our family. So it was important to go with someone with a reputation like Grennan.They stand behind that reputation. There will be always miscommunications and deviations from plan with any project this size (from quote to final install), but Grennan immediately addresses all issues and concerns. The owner was great upfront with advice on color/style (the 3D render tool is great), the overall projects manager Brandon and our individual project manager were highly communicative and took personal ownership of issues, and the team assigned was fantastic. Brian and his crew treated my family and our property with so much care - INCREDIBLE respect - and answered all questions promptly.We're really happy with how it turned out.
