Very quick and polite.Posted on Google Damola St.DanielsTrustindex verifies that the original source of the review is Google. The team at cornerstone are outstanding. They were extremely understanding and patient as we navigated our first commercial storefront buildout. They executed our vision flawlessly. Their team were also extremely communicative and supportive throughout the project. In the end, we were extremely impressed with the work they did. Thank you @Cornerstone!!Posted on Google Stuart WechslerTrustindex verifies that the original source of the review is Google. Called these guys at the last moment to help load some junk. They have me a reasonable estimate over the phone . Two young guys arrived and immediately started to work on a very, very hot day. They completed the job quickly efficiently and very pleasantly. They actually charged me significantly less than the estimate. I would use them again and cannot recommend them highly enough Using them was a pleasure.
