We understand that people have busy schedules, and finding time for everyone to attend an appointment can be challenging. That’s why we don’t require all decision-makers to be present for a consultation. However, having everyone involved can make the process more efficient, as it ensures preferences, questions, and decisions are addressed upfront. If coordinating schedules isn’t possible, we’ll work with you to provide the necessary information in a way that suits your needs.
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.
