About Austin Retrofit

Content Image

     Austin Retrofit started as a part time father-son endeavor by John C. and John E. Nelson, to establish a college fund for John E. or Junior as he is known. We experienced great success and we soon became a full time business. We have over seventeen years experience installing windows and doors.
     Today, it is still a father-son business and one of the few window and door replacement companies that is not franchised. We are a totally Austin-based company that specializes in window and door replacement. Lately, many companies began offering window and door replacement service along with their other services. However, window and door replacement has not been their specialty for years as it has with our company.
     At Austin Retrofit, we offer the most competitive prices in the market. We don't hard sell our services but let our experience and products convince customers that we are the best.


      John E. runs our installation crew and unlike many companies, he works full time, side by side with the installers. John C. is in charge of procuring work, finances and administration. Cody Marwitz, who was an installer for us for several years, is now our Sales Manager and is responsible for bidding, home consultations, purchasing and scheduling.

Facts about our company:


  • We are not a franchised company that has to send a large portion of our profits to the home office.

  • We are not tiered like some companies that you buy the windows from and they then subcontract out the installation.

  • With Austin Retrofit, we don't deal in gimmicks or hard sell.

  • We offer the lowest prices and the best quality.

  • Our customers can choose any window brand but the Simonton brand that we specialize in is the number one window in the nation. They have won the J. D. Power Award for the last three years, and won two awards this past year.

  • We use certified installers.

  • We can provide potential clients with hundreds of current referrals from previous customers.

  • John Jr. is a certified installer and instructor through the InstallationMastersTM Certified Installers, he is now the only instructor in the state of Texas.

  • Austin Retrofit is an EPA Certified Lead Safe Renovation Firm.
