San Marcos homeowners may be balancing intense sun, highway or neighborhood noise and rising cooling demands. We explain which window components address each concern and where an upgrade will make the biggest difference.

North on I-35, past New Braunfels

San Marcos is the Hays County seat, with city limits reaching into Caldwell and Guadalupe counties. We reach it on I-35 to serve homes near downtown, around the university and on the newer edges of town.

Interstate and street noise

I-35 runs right through San Marcos, and windows with excellent sound insulation help keep that traffic hum out of living space.

Cooling bills creeping up

Low-E glass options limit the solar heat gain that makes an air conditioner run longer on bright Central Texas afternoons.

Old houses, new standards

Older homes in the city's historic neighborhoods can move to ENERGY STAR rated units in styles that suit the original look.

Fixed glass for quiet rooms

Where a room facing I-35 needs no breeze, a fixed picture window gives traffic noise one less path into the house.

There may be. San Marcos has several local historic districts, and the city's Historic Preservation Commission reviews certain exterior changes through a Certificate of Appropriateness. If your home sits in one of those districts, check with city planning staff before ordering windows. We can supply style, material and size details to support your application.
