Six Reasons North Atlanta Homeowners Choose Us For Windows.
We're not the cheapest window installer in the area. We're the one that actually delivers the energy savings the manufacturer promises.
Energy Star Certified Installer
We're authorized to install and certify Energy Star rated windows — unlocking federal and Georgia energy rebates your project may qualify for. Most installers can't offer this.
In-House Installers — Zero Subcontracting
Every window is installed by a Siding Depot in-house employee — trained, certified, and insured. We never hand your project to a subcontractor the day it starts.
Built for Georgia's Heat & Humidity
Low-E double-pane glass with argon-gas fill blocks Georgia's radiant heat and keeps humidity out. Not a Northern-spec window installed in the South — the right product for your climate.
Written Estimates — Locked Price
Detailed, itemized written estimate before any work begins. The number we quote is the number you pay — no change orders, no mid-project surprises.
Precision Measurement & Custom Order
Every opening is measured twice. Every window is custom-ordered to your exact dimensions. No field-cutting, no shimming to cover a bad fit. The window fits because we measured right.
15-Year Workmanship Warranty
Our installation warranty covers air infiltration, seal failure, and operational defects for 15 years — on top of the manufacturer's glass and frame coverage. The most complete window warranty in North Atlanta.
