How do you test windows for your reviews?

Our window reviews are based on 15+ years of professional installation experience, energy efficiency testing, durability assessments, and real customer feedback. We evaluate thermal performance, weatherproofing, hardware quality, and long-term value using NFRC standards and real-world installation data.

Are customer reviews verified?

Yes, all customer reviews are from verified purchases and installations. We require proof of purchase and installation confirmation before publishing any review to ensure authenticity and credibility.

What makes a window energy efficient?

Energy efficient windows feature low-E glass coatings, low U-factor ratings (0.30 or lower), appropriate SHGC ratings for your climate, quality weatherstripping, and Energy Star certification. We test all these factors in our comprehensive reviews.

Do you offer installation for reviewed windows?

Yes, we provide professional installation services for all windows we review. Our certified installation team ensures proper fitting, sealing, and performance optimization with full warranty coverage.

How often are reviews updated?

We update professional reviews quarterly and continuously add new customer reviews as installations are completed. This ensures our content reflects the latest product improvements and real user experiences.
