We recently had our doors and windows replaced and the experience exceeded expectations from start to finish. Chris was knowledgeable, patient, and never pressured us. Chris took his time to explain our options and helped us choose the best products for our home.
Fidel and Oscar did an outstanding job with the installation-arriving on time, working professionally and courteously and showing great attention to detail while keeping the work area clean and treating our home with care. The workmanship was excellent and the final result looks amazing.
Communication throughout was clear and consistent and we couldn’t be happier with the outcome. We highly recommend Clera doors and windows for their quality, first class service and commitment to their customers- five stars all the way!
