Window Replacement in Galveston, TX
The Window Source of Houston brings window replacement to Galveston from our shop in Tomball, about seventy-four miles northwest. The island is less than three miles across at its widest, so every house on it sits in salt air.
Windows that have spent years in it tend to stick in their tracks and let water in at the sill when a storm comes through.
What salt air and storms do to windows on the island
Salt settles on frames, tracks and hardware every day, and it’s hard on metal. Aluminum frames pit and turn chalky, and the parts that make a window work, the locks, balances, hinges and rollers, get stiff before they seize.
Storms bring the water. Wind off the Gulf drives rain sideways at the seam between window and wall. Once the sealant and flashing around an old window have given out, that water ends up in the sill and the framing below it. Older wood windows rot from the sill up, and older aluminum ones work loose in their openings and rattle whenever the wind picks up.
When a Galveston window needs replacing
Start with the metal. White crust or pitting on an aluminum frame, a lock that fights you, and a sash that won’t stay where you put it all mean salt is working on the metal. Then look at the glass and the wall around it. Fog between the panes, a draft you can feel at the frame, or a water stain under the sill after a storm means the seals or the flashing have failed.
A lot of the island’s windows have had a long time to get there. By the Census Bureau’s 2020–2024 estimates, about one in five of Galveston’s homes and apartments is in a building from before 1940, and about six in ten were built before 1980.
None of that means every window on the house has to go at once. If the Gulf-facing windows are finished and the others still have some life in them, we’ll tell you so at the estimate.
Galveston window replacement and the rules around it
We take each window out frame and all, set a new one made to the opening’s measurements, and seal it with our Leak Shield flashing system at no extra cost. The Window Source of Houston guarantees that installation for life, and if you sell the house, the guarantee goes with it. Exterior doors get the same treatment, while repairs to existing windows, cut glass, and storefront or commercial work are outside what we do.
All of Galveston County is inside the Texas Department of Insurance’s designated catastrophe area, where the Texas Windstorm Insurance Association is the insurer of last resort for wind and hail. TWIA lists windows and entry doors among the improvements that need a windstorm certificate of compliance before a property qualifies for its coverage.
For a WPI-8, the certificate issued during construction, a TDI inspector or an appointed engineer checks the work while it’s underway. Certifying it after the fact takes an inspection by a licensed engineer, which TDI says can cost more. If the house is on a TWIA policy, bring it up at the estimate.
Houses in the city’s locally designated historic districts, such as the East End and Silk Stocking, have one more step. Replacing windows on the front of a house there, or changing what they’re made of, goes before the city’s Landmark Commission, a review the city puts at about four to six weeks. The standards it applies favor repairing original windows and list vinyl as an inappropriate replacement material. If your house is in one of those districts, mention it when you call.

“I got several quotes, and Jairo was the only one who brought samples and took the time to give us a demonstration. The office stayed in communication with me every step of the way… Edwin’s installation team worked quickly and professionally.”
“Replacing my parents’ original builder-grade windows in their 25+ year old home was one of the best investments they’ve made… They’ve already noticed lower electric bills, less outside noise, and a cooler, more comfortable home that’s much easier to keep at a consistent temperature.”
