We used GreyRock Exteriors last year to replace all of our siding due to damage from a hail storm. They did an amazing job. Phil was amazing and easy to work with. And the installer, Jason, was meticulous with the installation, making sure to clean up every night before he left!! We would totally recommend GreyRock Exteriors.

Thank you very much for all your work during this project. Jason and David represented Greyrock extremely well. Jason’s professionalism and attention to detail was much appreciated. David’s workmanship was very, very good and he was easy to work with.

These guys are awesome!!!! I contacted them one week enquiring about what it would cost to fix my shingles. Phil got back to me immediately and set a time to see the damage at no cost! Now, my roof is better, thanks to Greyrock Exteriors. Would I use them again? ABSOLUTELY! Give them a call and join my joyful experience!

Ok so normally doing any work to your house can be stressful and scary but not with Jason, he absolutely has extensive knowledge and is absolutely thorough at making sure you understand your options and everything you need to know. He is completely certified and brings a lot to the table. He is very honest and reliable as well and was able to provide us full estimates fast. They back up all their work and do a quality job the FIRST time. Highly recommend doing business with this company and save yourself time and headaches.

We are very pleased with the work performed by GreyRock. I have used many other contractors over the years but none were better than GreyRock. Phil Taylor was totally focused on our job – his attention to the smallest detail was appreciated. Also, his communication with me regarding timing, etc. was exemplary and much needed due to the poor weather conditions this summer. Despite any little setbacks (not the fault of GreyRock), the finished product is outstanding. I have nothing but respect for Phil and unconditionally recommend him and GreyRock to future and potential customers.
