Window Features

Energy-Efficient, Sustainable Design

Ultrex ® fiberglass provides an insulating barrier between extreme weather temperatures. Ultrex® is made predominantly from silica sand, a safe and abundant resource. Enjoy the look of traditional wood windows without the rot.

Beautiful Design

Infinity windows arrive with smooth corners, traditional details, and slim profiles to maximize your view. Infinity fiberglass windows brighten your home with abundant natural light.

Durability & Low Maintenance

Infinity windows have very low thermal expansion rates. The patented commercial grade finish resists the harshest weather conditions unlike vinyl, wood or composite windows. The long term stability reduces the risk of seal failures and air leakage through the window.

Energy Efficient Glass Options

Infinity windows offers many glass options for energy efficiency, code compliance, sound reduction, and aesthetics. Infinity windows offer U.V. protection and have some of the highest performance ratings to keep you comfortable year round.

The NGRW Experience

North Georgia Replacement Windows prides ourself on superior customer service. From our free proposal offer to our “red carpet experience” and our Lifetime Service Warranty, the homeowner’s satisfaction is our top priority. Watch our video for details on our concierge level of service and why we are considered "the best of the best!"







A Phone Call

  • When you call or fill out our web form, we will call you back to find out how NGRW can make you feel more comfortable in your home.
  • We’ll ask a few questions to make sure that NGRW is the right fit for you. We will answer any questions you may have for us.
  • Finally, we’ll schedule a convenient time to meet at your home, or you can come to our showroom.

A Meeting

  • Whether you are looking for replacement doors or windows, meeting with one of our knowledgeable consultants is the first step. Please, plan on spending at least an hour reviewing samples, discussing your options and planning for your home's makeover.
  • You’ll find your North Georgia consultant easy to work with. We believe in a no-hassle, no-pressure, no-gimmick approach.
  • Based on your home, your style preferences, your budget, and how much longer you plan to stay in your home, we will be glad to make specific recommendations.
  • We’ll take measurements and gather other necessary information for preparing a price quote. If you are interested in taking advantage of one of our finance offers we will walk you through the process.

A Proposal

  • The proposal you receive will include everything necessary to complete the project, so there are no unexpected costs later.
  • Most homeowners understand that new windows and doors aren’t expenses — they’re investments that will pay off in lower energy and maintenance costs over time.

An Agreement

If you prefer to only replace some of the windows in your home now, and the rest of the house later, you’ll have that opportunity. Once you sign and return the Agreement, we’ll get to work custom-creating your windows and doors. Your custom ordered windows or doors will take approximately four to six weeks. Before your custom windows or doors are ready, we’ll contact you to schedule a time for your install.

A Project Completed

  • With North Georgia’s ‘Red Carpet Approach,’ we aim for minimal disruption of your home.
  • If you have any questions or concerns during the process, your onsite project manager is available to assist you.
  • After the windows or doors are installed, we’ll do any ‘finishing’ work that’s necessary, and thoroughly clean up and vacuum the areas where the work was completed.
  • Finally, you and your onsite project manager will walk through and inspect everything to make sure everything is perfect.
