Mathis Design-Pressure Rated Windows & Doors — Insured

Call (855) 393-3484 or send the form and we schedule a site visit in Mathis, usually within a couple of days. You get a written, itemized free estimate with materials and scope spelled out — no verbal ballpark, no pressure, and no charge whether you hire us or not. Se habla español.

We also serve Bishop, TX and the rest of the Coastal Bend. Everything starts at the Corpus Christi Window Replacement homepage.

Corpus Christi Window Replacement covers the same range of work in Mathis that we do in Corpus Christi — nothing is carved out because the address is a few miles up the road:

• Bay and Bow Windows — This is the page where we most often talk a customer out of the product they called about. A bay window adds real floor space and light to a room, and on an exposed elevation here it is the hardest assembly we fit to make behave.
• Picture and Architectural Windows — The physics of a fixed window are simple and not on your side. Wind load arrives as pressure spread across the whole surface, so doubling the area of a lite roughly doubles the total force the frame and the anchors have to carry.
• Egress Windows — An egress window is the opening a trapped occupant climbs out of and a firefighter in full turnout gear climbs in through. The residential code sets the dimensions, the city enforces them at inspection, and here they collide with the pressure requirement.
• Impact and Hurricane Windows — Impact rating and pressure rating are two different tests, and a window can pass one and fail the other. Confusing them is the most expensive mistake made on this coast, because the product that survives a flying two-by-four is not automatically the product that survives the pressure that threw it.
• Sliding Patio Doors — A sliding patio door is the largest hole in the wall of most houses and the opening that fails first. Everything hard about a window is worse on a door: more area, more load, a threshold at floor level, and real panel weight.
• French Doors — A pair of French doors has no jamb in the middle. Two leaves meet in open air, held together by an astragal and whatever the hardware does at the top and bottom, and that center joint is the entire structural argument for how the door is specified on this coast.

Mathis sits in San Patricio County with a population of roughly 4,333 at the 2020 census, close enough to Corpus Christi that crews move between the two constantly. Local landmarks and corridors residents know well include Wesley Seale Dam, the bluff above the reservoir.

Local knowledge is not a marketing line here. Mathis properties share soil, weather, permit rules and construction eras with the rest of San Patricio County, and a window contractor who works the area weekly already knows what fails locally and what holds up. That is the difference between a bid and an accurate bid.
