What homeowners say after working with Sage.

  • “Terry did a great job with my front door replacement. He was very professional, came prepared with a wealth of information and options. Most impressively, he was able to price match very credible competitors.”
    Jordan Harvey, January, 2026
  • “I couldn’t be happier with my experience with Sage Home Improvements! From start to finish, the process of replacing 8 windows in my home was smooth, professional, and stress-free. The team was incredibly knowledgeable and took the time to answer all my questions, helping me choose the best options for my home and budget.”
    Stephanie Turner, November 2026
  • “Terry and his team were so friendly. He came out and gave an estimate for a broken window upstairs. He was back the next day with a window that matched and it was installed before I knew it.”
