  We absolutely loved our new windows – they’ve completely transformed our home! From the start, the installers were fantastic – punctual, really careful, and incredibly courteous. The quality of the windows themselves is outstanding; it’s clear they’re a high-end product. Honestly, we’d been struggling to find a replacement window solution; we were put off by the upkeep of wood and the cheapness of vinyl. Aluminum seemed like a good choice, but we were worried about heat transfer. Glass fiber was a brilliant solution! And we definitely recommend adding the awning upgrade – Greg explained how it would dramatically improve the view, and it truly did! The installation was surprisingly neat – almost like there was no cutting or disruption, and the team did a fantastic job minimizing the work on our stucco exterior. We were also pleasantly surprised by the price; it was lower than we anticipated, which made us even happier. It’s great to find a company that delivers exceptional quality and value. Seriously, look at those windows! Thank you so much, Greg! report abuse

Communication was excellent throughout, from the initial sales process to scheduling, and the installers were always punctual. Honestly, it was a 5-star experience!” report abuse

  Capstone did an absolutely fantastic job renovating my home, and I’m so pleased with their work on my new door. Greg and Audrey were fantastic to work with – they were both incredibly friendly and always kept me fully informed throughout the entire process. They consistently followed up with updates and checked in with me after each stage, which made me feel really valued as a customer. What really impressed me was the speed and quality of their work. They transformed an old 3-panel door into a stunning French sliding door in under a week, and honestly, you wouldn’t even know it used to be there! I’ve already recommended them to a friend, and I’ll definitely be using Capstone for all my future window replacements too. report abuse
