When a banking error occurred he was quick to help us resolve the issue.<br><br>On the two days of the install Alex and his team did a fantastic job working quickly and carefully to remove the old windows and install the new ones.

    Full process was great. Crew was able to install over 30 windows in two days. They were kind, efficient, and from start to finish had excellent communication.

  • Kimberly Mella5.0

    Alex and his crew were amazing! All of them were very professional and courteous, and we are extremely pleased with the final product. If I had known they were going to be this beautiful I would have replaced the windows long ago. Alex put us at ease from the start, he definitely knows his craft! After getting 4 bids we chose The Window Source for their attention to detail, a quality product and an unbeatable price. Thank you!

Company Background

About The Window Source of San Antonio

The Window Source of San Antonio is a locally owned and operated window and door company led by Moses and Erica Torres, who serve as president and vice president. The company works from 6800 Fairgrounds Pkwy in the 78238 ZIP code on the city's west side. Its website says the team has more than 20 years of experience across replacement windows, doors and siding, and that one local crew stays responsible for scheduling, installation and long-term warranty service.\n\nThe product range covers vinyl windows in double-hung, double slider, casement, awning, picture, garden, single-hung and specialty shapes. Doors include entry, French, patio and storm doors. The company also installs replacement siding, patio covers and seamless gutters, so it can bundle exterior work. Brands and programs shown on the site include MI Windows and Doors, Prodigy, Ascend siding, ENERGY STAR, NFRC and AAMA.\n\nThe company describes a double lifetime warranty that transfers to a later owner, and advertises sound insulation and windows suited to South Texas heat and storms. Financing is advertised, including a promotion of 0 percent interest for 72 months with 0 dollars down, which carries an asterisk on the site, so read the conditions. The site also publishes local guides for neighborhoods including Alamo Heights, Monte Vista, Castle Hills, Leon Valley, Olmos Park and Terrell Hills.\n\nThe Window Source of San Antonio has 4.7 stars from 175 Google reviews, read November 3, 2026. A customer quoted on the company site praises a crew led by Alex for installing energy-efficient windows in a home of 21 years. The website is newly built, and its phone number, 210-796-9574, differs from the Google listing, which shows 210-549-4204.\n\nThe Window Source suits homeowners who want a locally owned team, vinyl windows with sound and heat performance claims, and a transferable warranty. It suits less well buyers who want wood or fiberglass lines. Before booking, ask for the quote in writing with the window series and U-factor, the full warranty text, and proof of insurance. Texas does not license window installers at the state level. Homes built before 1978 should be handled with lead-safe practices, and historic districts such as Monte Vista have exterior rules.
