It was a pleasure to work with Cornerstone Building. Justin and Mark were professional and easy to work with from start to finish. They assured that the work would exceed my expectations, and it did. The replacement roof is of high quality and the workers were efficient and on time throughout the project. The communications were excellent and they kept me informed of progress and potential delays. I highly recommend Cornerstone Building and Restoration! ~ Customer, Rockville, Maryland

Cornerstone replaced our siding and gutters. Did an awesome job. From beginning to end they were professional and responsive. Helped us with navigating the insurance process. We also had them replace rotting wood trim. The price was very fair. The finished work on the siding and trim looked great. The crew was careful and punctual and cleaned up after the job was finished. I highly recommend Cornerstone. ~ Customer, Bethesda, Maryland

Cornerstone worked our primary home. They examined our roof to verify the type of damage we had noticed. We also had some leaks. After finding hail and wind damage, Cornerstone worked with us submit our insurance claim. Cornerstone was instrumental providing information to the insurance company and identifying issues with the insurance company’s own damage estimate. The insurance company’s offer was woefully low and incorrect. If we didn’t have Cornerstone’s expertise working with us, we would not have received the appropriate compensation. The insurance company eventually agreed with Cornerstone’s accurate assessments. Cornerstone’s teams replaced our roof, installed new skylights, plastered and painted water damaged drywall, and replaced gutter systems which were under duress and not keeping up with the flow. If anything went wrong at our site, Cornerstone quickly worked to address it and coordinate with us. We are very happy with the work and the teams responsiveness and efficiency. If we need a contractor again, they will be high on our list. ~ Customer, Maryland
