Our experience with Grieman Construction was exceptional. Aaron initiated contact promptly and promptly visited our residence to discuss the estimate, well before our agreement signing. He diligently worked with our insurance and went beyond to mediate their payment offer (while they weren't very cooperative). We were frequently updated about the roofing installation timeline, and Aaron was accessible even out of business hours to assist with any issues. The roofing crew expertly installed the roof, and it appears stunning. We were impressed by their professionalism and dedication throughout the whole process.
