Energy-efficient upgrades are at the top of every homeowner’s wish list, and nothing delivers year-round comfort like properly installed double pane units. These insulated glass assemblies can slash utility bills by up to 30 percent, but only when material and labor costs are aligned with project goals. CountBricks uses AI-powered estimates and real-time supplier feeds to calculate an accurate double paned windows cost before the first sash is removed.
1. Economy vinyl: Ideal for flips and rentals, offering an airtight seal at the lowest upfront price.
2. Mid-grade composite: Balanced price-to-performance, popular for owner-occupied homes.
3. Premium fiberglass or clad wood: Highest R-value and curb appeal, commanding the largest share of the budget.
• Standard 3'×5' double-hung windows carry the baseline price.
• Custom picture, bay, or bow configurations add square footage and engineering time.
• Egress-code bedroom windows require reinforced hardware and may increase cost.
• Low-E coatings improve heat reflection for minimal added cost.
• Argon or krypton gas fills raise insulation performance by 10-15 percent.
• Laminated panes provide enhanced soundproofing at a premium.
• Full-frame replacement involves removing trim, flashing, and sills—higher labor hours.
• Retrofit pocket installs slide new units into existing frames—faster and less invasive.
• Structural modifications for larger openings require a licensed framing crew.

When the Bailey family purchased a 1940s Cape in Portland’s Deering Center, original wood single panes drained heat all winter. Their goals: cut utility costs by 25 percent, maintain historic curb appeal, and avoid a painful renovation timeline.
• 18 openings across two stories
• Combination of double-hung and fixed picture units
• Mid-grade composite frames with Low-E/argon glass
The initial voice estimate projected $16,950, including trim preservation and lead-safe practices. Thanks to real-time supplier bidding inside the CountBricks platform, the final invoice closed at $16,105—5 percent under the AI projection and 14 percent below the average market quote our client received offline.
After the first full heating season, gas consumption dropped 28 percent, and interior surface temperatures near windows rose by an average of 8°F. The payback period is now forecast at 3.2 years—well ahead of the Bailey’s five-year goal.
