  • “I had the pleasure of working with Cornerstone during the renovation of my new home. While vacationing in Hawaii, I was inspired by the seamless indoor/outdoor living lifestyle. I was thrilled to And a company that could bring that same experience to my home. They helped me visualize the transformation through their design, and the results completely surpassed my expectations.”

    Tom Gallaway, Coto de Caza

  • “From start to finish, we found that Cornerstone Openings has stood behind their promises and their products. I would not hesitate to engage Cornerstone Openings and Sean’s team in any major project that requires new doors and windows.”

    Mr. Tang, Laguna Beach

  • “The install was completed in four days and the results are spectacular. The doors were installed perfectly and the stucco you replaced on the outside of the doors matches perfectly. I really appreciated how your team went the extra mile to help us relocate some of our exterior lights outside of the doors.”

    Andrew Tinseth, San Clemente

  • “Throughout our build, we worked with over 20 different subcontractors, and Cornerstone Openings stood out above them all. Their service, communication, and attention to detail were unmatched. I can recommend them with 100% confidence—the final products and experience were truly superior.”

    D. Hancock, San Clemente
