Corpus Christi Window Replacement provides professional residential window installation in Corpus Christi, TX for residential and commercial properties across the Coastal Bend. Wind-driven rain is the load that decides whether an installation here was any good. Not heat, not even the design pressure on the label. Rain arriving horizontally at a joint that was never designed to be watertight.
Which is why nothing in our details tries to be watertight. The sill pan under every unit is the assembly that makes the installation work, and its purpose is to collect whatever gets past the sealant and send it back outdoors before it reaches framing.
A pan does that with three features. A slope toward the exterior so gravity has a direction, a turned-up dam at each end so water cannot run off sideways into the stud bay, and a raised dam at the back so nothing can creep inward under the frame. We fit one-piece pans rather than building them out of tape in the hole.
The pan is only as good as the laps around it. Jamb membrane lands over the pan upstand, head flashing goes over the jamb membrane, and all of it ties into the drainage layer of the wall so the path continues past the opening. Get that order backward and the flashing becomes a funnel.
Anchorage is the other half, and on this coast it is specified rather than chosen. The evaluation report for the unit names a fastener, a spacing and an embedment into structural framing, and we fit to that report. A pattern improvised on site is not the condition the unit was tested in.
The perimeter joint gets treated as a working joint. Width sized so the sealant can stretch, backer rod to shape the bead, and a low-modulus sealant because the frame and the wall move at different rates in this humidity. Then the interior side is sealed continuously before casing returns.
We would rather prove it than describe it, so an installed opening can be water tested in place, which is the only way to learn whether a detail works before a storm teaches you. That test takes an hour on the first opening, it is worth asking for where a wall type is unfamiliar, and it has changed how we handle more than one assembly in this city.
Permits come through the City of Corpus Christi on the editions the city has adopted, and from April 2026 windstorm certificate applications are certified against the 2024 code. Texas issues no state contractor license in this trade, which is exactly why the permit, the insurance certificate and the manufacturer's evaluation report are the three documents worth collecting.
Our recommendation is harder to sell than a window. If the framing around an opening is soft, or the drainage layer behind the finish has failed, the purchase in front of you is repair and not fenestration. Buy the carpentry, then buy the unit, and ask whoever quotes the work to show you the pan while it is still visible.
Our insured team brings the right materials and equipment to every job — positive and negative design pressure ratings per opening, AAMA/WDMA/CSA 101/I.S.2/A440 performance grade, tested size tables published in product evaluation reports, large-missile classification under ASTM E1996, rated structural mullions with published load tables, fully tempered and heat-strengthened lites sized to the load — and backs the work with a written workmanship warranty. We serve Corpus Christi and nearby communities including Portland, Kingsville, Robstown, Rockport.

Materials, equipment and how we do residential window installation
The difference between residential window installation that lasts and residential window installation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with positive and negative design pressure ratings per opening, AAMA/WDMA/CSA 101/I.S.2/A440 performance grade, tested size tables published in product evaluation reports, large-missile classification under ASTM E1996, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Corpus Christi job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the Coastal Bend means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Corpus Christi Chooses Corpus Christi Window Replacement
- ✓The rating on your quote comes from the tested size in the evaluation report, so you are told what the window you are buying does, not what the best unit in its family does.
- ✓We establish which of the county's three windstorm zones the address sits in before any product is priced, because the required load rises with the square of the design wind speed.
- ✓Glass is chosen opening by opening rather than ordered as one package, so a shaded north wall is not paying for the coating a west wall needs.
- ✓Where an opening outruns the tested size table, we change the shape or add a rated structural mullion instead of quietly quoting a unit that will not certify at that size.
