North Georgia Replacement Windows

What North Georgia Replacement Windows does

North Georgia Replacement Windows (dba NG Windows / North Georgia Windows) is a privately held, Georgia-based window and door replacement contractor founded around 2004-2005 and headquartered in Alpharetta, Georgia (legal entity NG Windows, Inc.). The company sells, installs, and services replacement windows, entry and patio doors, exterior shutters, and related products for residential and commercial customers across Georgia and Tennessee, operating through a direct-to-consumer model that combines a physical showroom (over 50 doors on display), in-home sales consultations, phone sales, and an inbound website channel.

The company's core product is Infinity by Marvin fiberglass replacement windows, for which it holds exclusive Georgia dealer status. These windows use the patented Ultrex® process, a pultruded fiberglass positioned as eight times stronger than vinyl and exhibiting 87% less thermal expansion, supporting the company's premium energy-efficiency positioning. NG Windows supplements the exclusive Infinity line with authorized-dealer relationships across multiple door brands (ProVia, Therma-Tru, Plastpro, Phoenix Iron, MaxCraft, Euro Wall) and Atlantic Premium Shutters, and offers licensed general-contractor services for four-season room conversions. The company is contracted through Costco's window installation program and carries a 4.9-star rating across 696 customer reviews, with an endorsement from Atlanta TV meteorologist Glenn Burns.

Revenue is generated primarily through one-time sales-and-installation transactions at quote-based pricing, supplemented by third-party financing (12-24 month no-interest and extended low-interest options) and transaction fees on financed deals. The business employs 11-50 staff, operates a single showroom, and uses Salesforce as its CRM with Cox Media Group as an advertising partner. In 2024, the company expanded into Greater Nashville and Greater Chattanooga, marking its first geographic expansion beyond Georgia in 20 years of operation.
