Cost Savings

“When we first heard about the cast-in-place windows we were a little hesitant. After installing them our crew quickly became fans—we estimate they saved about one hour per window on formwork and another two hours on glazing. On this project, we installed 28 cast-in-place windows and estimate a total savings of roughly 84 man-hours. Overall, we’ve been very satisfied with the product. Customer service was also fantastic. Due to a discrepancy in our drawings, we ended up short one window. Once the issue was discovered, they had a replacement onsite within two days—personally delivered by our sales representative.”
