Most projects are completed in just one day. Our small, experienced crews typically install 8–10 windows per day and work one opening at a time, carefully measuring each opening and window as they go. This approach minimizes disruption to your routine while ensuring precise, professional, high-quality results.

It’s difficult to give anyone a general price estimate because there are many factors that affect the cost of a window. Unless you’re purchasing stock windows from a big box store, window costs will vary based on the manufacturer, quality, materials used, style, and the type of glass package included. We have included a pricing example for Andersen 100 Series windows in the post linked below.

Window pricing varies because no two products or companies are exactly alike. Differences in brands, materials, and energy efficiency features, customization options, installation expertise, and even vendor relationships all influence the cost. Additionally, some companies may not include key factors like labor, warranties, or additional fees in their initial quotes. It’s important to compare quotes carefully and consider the overall value—not just the price—when making your decision.
