Detail orientated, meticulous, high quality, professionalism and integrity are a few words to describe Cornerstone Builders. The Cornerstone team completely dismantled and then remodeled our kitchen and completed numerous other projects throughout our 21-year-old home. The team took our vision and skillfully executed the plan to a final product that is both stunning and functional. Cornerstone Builders exceeded our expectations.
The Cornerstone Crews were careful to be as least disruptive as possible during construction. They clean up every evening, as well as hiring a professional cleaning crew at the conclusion of the project. The team did an excellent job calculating budgets, communicating schedules, and answering all questions in an extremely timely manner. Their standard of excellence was above our expectations; if they saw something that could be improved, they took the lead in talking to their craftsmen. Collaborating with the Cornerstone team to complete our remodel from start to finish was an exceptionally positive experience. Cornerstone Builders receives our highest recommendation-beyond five stars!
