Siding Depot replaces windows across Marietta, Alpharetta, Milton, Canton, Woodstock, Roswell, Kennesaw, Johns Creek, Sandy Springs and Acworth — covering Cobb County, Cherokee County and Fulton County in Metro Atlanta. We specify Energy Star double-pane Low-E windows for Atlanta's climate zone (3A/4A), where AC runs much of the year. Most full-home window replacements in our service area generally run $7,000–$18,000, and according to Energy Star, certified Low-E packages can meaningfully reduce summer cooling costs.
Energy Star® Certified Low-E Double-Pane Windows
Energy-efficient windows are a long-term investment. Use this checklist to verify thermal performance specs and installation certifications for Georgia's climate.
Energy Star certified product
According to Energy Star, look for U-factor < 0.30 and SHGC < 0.25 for Atlanta's climate zone (3A/4A) — the specs that meaningfully impact summer cooling costs.
License & insurance
Verify a current Georgia GC license plus general liability and workers' comp before any deposit changes hands.
Itemized written estimate
Insist on per-window pricing, frame material, glazing package, install method (insert vs. full-frame), and trim/wrap details.
Manufacturer-trained installers
Improperly installed windows can leak air and water no matter how good the product. Ask who trains the install crew.
Local reviews after one summer
Drive past jobs from 12+ months ago. Caulk lines and trim wraps tell you a lot about install quality.
Realistic timeline
A standard 15–20 window swap typically takes 2–3 days for an experienced crew. Substantially faster timelines may indicate rushed flashing or insulation work.
