I would like to thank Chris from Keystone Construction and Roofing for all their efforts during and after our office build out. Every step of the way from our initial conversation to final inspection approval, they have been pleasure to work with. This project was absolutely painless thanks to their attention to detail. All of the subcontractors they brought to the site were reliable, clean and trustworthy. Not only did they execute their jobs well, but they all spoke very highly of Keystone Construction. This is truly a reflection of their character and integrity. Their daily presence afforded me the ability to continue my day to day work load without interruption during this entire project. There were no surprises thanks to their experience and knowledge. I never would have believed it could have gone so smoothly. Furthermore, I appreciate their patience and resiliency with the last minute changes made on our part. I strongly recommend Keystone Construction, they did great job.
