Frequently Asked Questions

Discover answers to common questions about our products, ordering process, and services to assist you promptly.

What does it mean to get a quote on replacement windows without an in-home salesperson?

The traditional window sales approach can take 3 to 4 hours with high-pressure tactics, often involving a pushy salesperson visiting your home. It requires both decision-makers to be present and inundates you with unnecessary information, leading to accepting a quote you may not fully grasp. This experience can be frustrating and exhausting. Opting for a quote on replacement windows without an in-home sales pitch means avoiding all of this. At Sane Windows, our focus is on equipping you with the tools to make an informed decision and ensuring your satisfaction from start to finish.

How does your online quote process work?

Our online quote process is straightforward! You can explore products with transparent pricing. When you're ready, simply answer a few questions (approximately 5 minutes) and upload four images of your home. Your quote will then be emailed directly to you, allowing you to review it at your convenience. There's no need to endure a lengthy in-home sales pitch or deal with high-pressure sales tactics. 

Alternatively, we're happy to visit you (appointments approximately 45 minutes) to quickly measure your windows and doors, show you product samples, answer any questions, and provide you with a quote on the spot. 

If you're unsure about your options, that's perfectly fine! Contact us with your ideas, and we'll guide you through turning your home improvement dreams into reality.
