Trusted Windows & Doors for San Antonio Homeowners
Windows and doors fail slowly, then all at once in San Antonio. A window that sticks in June becomes one that won’t open at all by August, when the heat climbs past 100°F and you actually need the cross-breeze. A door that drags on the threshold for a year finally stops latching the week of Thanksgiving, and now you have no way to secure the house properly. We fix both problems the same way: a real person answers the phone at (409) 215-3468, we show up when we say we will, and the price goes in writing before any work starts. Preston Harley leads our Windows & Doors in San Antonio team, and he’s held every crew to The Garrison Standard since 2010: on-time arrival, upfront written pricing, work done by the book, and a 365-Day Done Right Promise that covers the full job in writing.
What Our Windows & Doors Service Includes
Window Installation
Whether you’re replacing one failed window on the west side of your San Antonio home or doing a full-home upgrade, we handle the entire job from measurement to final trim. We remove the old unit, correct any rot or settling issues in the framing we uncover, install the new window level and square, and seal it against the specific weather San Antonio dishes out: intense UV exposure, occasional hailstorms, and summer humidity. Before any work starts you’ll have a written line-item price covering the window, labor, disposal, and any framing repair, so there are no surprises when the final walkthrough happens.
Window Repair
Not every window problem means replacing the entire unit. Fogged double-pane glass, failed balances, broken latches, worn weatherstripping, and sashes that won’t stay up can often be repaired for a fraction of replacement cost. We diagnose the specific failure, explain what happened in plain language, and quote the repair before the replacement option, because the honest answer is sometimes the cheaper one. Our 365-Day Done Right Promise applies to every repair the same as a full install.
Door Installation
Exterior doors in San Antonio take a beating from the clay-heavy alkaline soil shifting under the slab, which throws frames out of square over time. We install entry doors, patio doors, French doors, and storm doors with attention to what’s underneath: the threshold, the hinge pockets, and the weather seal. A door we install latches clean, seals tight against drafts, and swings easy, because we square the frame itself, not just the slab.
Door Repair
Sticking doors, sagging slabs, broken hinges, deadbolts that no longer line up with the strike plate, and thresholds that have cracked under years of sun and foot traffic. We fix the cause, not the symptom. That means re-shimming hinges, replacing worn hardware, correcting the strike plate alignment, and when needed, re-hanging the door in the opening rather than just sanding the edge until it sort of works. Every repair leaves the door sealing properly and locking securely, which matters most at night when it’s your only barrier.
Sliding Glass Door Service
Sliding doors in San Antonio homes fail most often because the rollers wear out or the track fills with dust and grit that grinds the wheels down. We replace rollers, realign tracks, restore smooth operation, and repair or replace the locking hardware, which on older sliders is often the weak point. Whether it’s a patio door off the kitchen or a master-bedroom slider that hasn’t moved smoothly in years, we get it gliding again and latching tight.
Weatherproofing and Sealing
San Antonio’s droughts and downpours alternate hard, and any gap around a window or door means hot air in, cooled air out, and higher energy bills every month. We inspect and replace weatherstripping, door sweeps, caulking, and exterior seals, and we identify where the real leaks are, because it’s often not where you think. Proper sealing extends the life of the window or door and cuts down on the dust and pollen that slip through the gaps, which matters plenty in cedar season.

Brands We Service for Windows & Doors
We service Amarr garage doors regularly across San Antonio, and we know their spring systems, track geometry, and opener integration points well enough to diagnose the problem quickly, not after an hour of trial and error. Our crews carry common Amarr replacement parts on the truck, and we can source the rest same day from local suppliers, which means fewer second trips and fewer days spent waiting with a door that won’t close.
Wayne Dalton and Craftsman doors show up often in the neighborhoods we serve, and each has its quirks. Wayne Dalton’s TorqueMaster spring system is a different animal than a standard torsion setup, and Craftsman openers pair with a wide range of door weights and track styles. Raynor doors, when they appear, tend to be heavier commercial-grade units on high-use garages, and we service those with the same care. If your door carries a different name, that’s fine too. We service every major brand and most secondary ones, and we’ll tell you honestly if a particular part is worth sourcing versus replacing the door.
Signs You Need Windows & Doors Right Now
- Visible daylight around the door or window frame. If you can see light through the gap when the door or window is closed, air is moving through that same gap. In San Antonio that means your AC is working harder every afternoon, and in a storm it means water can get in. Small gaps become big problems fast once the rain comes.
- Windows that fog between the glass panes. Double-pane windows have a seal that eventually fails, and when it does, the trapped air carries moisture that condenses between the panes. That fog means the insulating gas is gone and the window’s efficiency is a fraction of what it should be. It won’t clear up on its own.
- A door that sticks, drags, or won’t latch cleanly. Doors don’t start sticking without a reason. It’s usually the frame shifting with the soil, worn hinges, or a slab that’s absorbed moisture. Beyond the annoyance, a door that won’t latch can’t do its job as a security barrier.
- Drafts you can feel with your hand, not just suspect. Hold your palm near the edges of your windows and doors on a cold January morning and you’ll feel the leak. Each drafty opening adds up on your energy bill, and the fix is usually simple weatherstripping or caulk, not a full replacement.
- Windows that rattle in the wind or don’t stay open. A window that slides down on its own has failed balance hardware, and a window that rattles has loose or broken glazing. Both are more than annoyances: they’re signs the window is no longer sealed or secured properly.
Our Windows & Doors Process – Step by Step
- 1
Call and talk to a real person. When you’re ready to schedule, call (409) 215-3468. A live person answers, asks what’s going on with your windows or doors, and schedules a visit that fits your day. No automated menus, no waiting for a call back.
- 2
We arrive inside the window we gave you. Our technician arrives at the scheduled time in a marked vehicle, in uniform, and background-checked. That’s part of The Garrison Standard, and it applies to every visit.
- 3
We diagnose and put the price in writing. We inspect the specific window, door, or sliding unit, explain what we found in language you don’t need a manual to understand, and write the full price for the job on paper before we touch a tool. If the job needs a part we don’t carry, we tell you then and there.
- 4
The work happens, the right way. We complete the repair or installation by the book, clean the work area before we load up, and do a final walkthrough with you so you know exactly what was done and why. The site won’t look like a crew was there.
- 5
Your 365-Day Done Right Promise is in writing. Every job carries a one-year written guarantee. If something fails in that window, we come back and make it right at no charge. That’s the same promise on a ol20 roller replacement or a $2,200 full door installation.
How Much Does Windows & Doors Cost in San Antonio?
Window and door work in San Antonio spans a wide range because the jobs vary that much. A sticking door that needs hinge re-shimming can run $120 to $240, while a full exterior door replacement with new hardware and weather sealing typically falls between $700 and $2,200 depending on the door style, material, and whether the frame itself needs correction. Sliding glass door roller replacement usually runs $130 to $250, and a fogged double-pane window replacement runs closer to $250 to $500 per pane, though the fix requires replacing the sealed unit, not just the glass surface. Weatherstripping and sealing work around doors and windows falls on the lower end, often $110 to $220, depending on how many openings need attention.
What actually changes the price: the condition of the rough opening, whether the frame has shifted with the soil, the size and material of the unit, and whether we’re dealing with one window or eight. The free estimate covers all of that, itemized, in writing before any work starts. That’s the part that matters most: the number we quote is the number you pay, and you’ll see it on paper before you agree to anything.
The price is always quoted and agreed before any work starts. The invoice matches the quote unless you approve a change in scope first.
