Energywise Installs Energy Efficient Replacement Windows in Austin, Texas

Greg Ginther, Owner of Energywise Windows & Doors Company

“Don’t listen to me or any company tell you they are the best!!!

I have 110+ of the highest possible reviews from my past customers, more than triple any other local or national window company in Austin.

​Look me up on Citysearch, Yelp, Google, Angies List, Merchant Circle, Yahoo Locals, and Insider Pages. See what your neighbors are saying about Energywise Windows & Doors."

My name is Greg Ginther and I care about my Family, my community and my Planet. I am on a mission to reduce your consumption of energy and thereby reduce the amount of money you spend every month on heating and cooling your home. We will also reduce the amount of CO2’s released into the atmosphere. Did you know that you can reduce up to 15,000 pounds of CO2’s a year through new energy efficient windows and doors installation for your home?
​
That equals cash in your pocket in energy savings. I sell high-quality replacement windows in Austin, Texas for less because profit is not the heart and soul of my business plan. Profit is more of a happy by-product. My main goal is to install as many Windows in as many Homes as possible with a fair profit built into every bid.

There is a Reason We Are Ranked #1

You get me, the owner, when you call Energywise at (512) 775-2342 (try it!) I will personally come to your home and consult with you about which replacement windows options are best for your situation. My goal is to save you money. Really! A salesman would never do this.

• I will always try to visit your job site on the day of the windows installation to make sure things are going well and you are comfortable with A-Z.
•  Energywise is a local, small company who buys locally manufactured high quality windows and we only operate in the Austin, Texas area (The mark of a TRUE local company).
• NO commissioned salesmen (no pressure tactics - honest), No outside crews and NO large advertising budget (and we pass the savings on to YOU). 
• My background is in customer service and I do everything in my power to make sure you are 100% satisfied.

My guarantee is to beat my competitors’ price on the highest quality windows and doors. I will not be able to sell my energy efficient windows and doors for less than the cheaper construction grade windows and doors you might find with some other dealers. My guarantee is on “High End Windows and Doors”.
