Window Replacement in Austin, TX

Failing windows show up as drafts, fog trapped between the panes, water stains under the sill, and trim that has gone soft at the corners. Driftwood Builders Roofing replaces windows across Austin and Central Texas as part of the same exterior envelope we already handle for roofing and James Hardie siding, so the flashing, the trim, and the wall behind them get done together.

Signs your windows need to be replaced

Windows rarely fail all at once. They give you a run of small symptoms first, and most of them are easy to live with until the wall behind them is involved. Watch for:
Construction area: exposed wall framing with yellow spray foam insulation, a blue ladder, and a window with greenery outside

Where window water problems actually start

Most of the failures we open up are not the window itself. They are the water management around the opening. Central Texas gives us long dry stretches followed by hard, wind driven rain, and that combination finds every joint that was sealed with caulk instead of properly flashed.

 

An opening should shed water on its own: a sill pan or sloped sill under the unit, flashing lapped over the water resistive barrier so gravity carries water out and down, and sealant acting as a secondary defense rather than the only one. When an opening was only caulked, that caulk eventually shrinks and splits, water gets behind the trim, and the sheathing and framing take the damage quietly for years before anything shows up on the inside. That is the same failure pattern behind rotting window trim, and it is why we open enough of the wall to see the real condition before we scope a replacement.

Two construction workers install a large window on a beige house, with plastic sheeting covering the opening and orange trim around the frame.

Repair or replace: how we decide

Replacement is not automatically the answer, and a new window set into a bad opening will fail the same way the old one did.

 

Repair or targeted retrofit often makes sense when the frame and the surrounding wall are sound and the problem is one specific part: worn weatherstripping, a failed balance or sash cord, damaged hardware, split exterior trim, or a caulk joint that needs to be cut out and redone correctly. A single failed component is rarely a reason to replace a whole unit.

 

Full replacement usually makes more sense when the insulated glass seal has failed and the unit is fogged, when the frame or sill itself is rotted, when the opening has to be opened up anyway to correct flashing, when several windows on the same elevation are failing together, or when the openings are part of a larger exterior project.

What we find on an inspection is not the same thing as a final repair recommendation. We show you photos of the actual condition at each opening and price the options separately so you can weigh them yourself.

Materials, installation, and doing it with the siding

On the installation side, the details that decide how long the work lasts are consistent: a sill pan or sloped sill under the unit, head flashing lapped correctly over the water resistive barrier, proper shimming so the window operates squarely, low expansion foam or backer rod rather than over-packed insulation, and exterior trim that is primed on all sides and sealed at the cut ends.

 

Frame materials each carry real trade-offs, and the right one depends on your home, the elevation, and your budget rather than on a brand pitch. Vinyl is the most common replacement frame and the least expensive. Fiberglass and composite frames are more dimensionally stable through heat cycling. Aluminum clad wood shows up on higher end Austin homes and on historic style openings. Full frame replacement lets us correct the opening itself, while insert or retrofit replacement is less invasive but keeps the existing frame and its existing flashing. We will tell you which one your opening actually needs.

 

Coordinating windows with a siding replacement is the single biggest efficiency in this work. When the siding is off, the water resistive barrier and the openings are exposed, flashing can be integrated correctly instead of retrofitted, and the trim and siding go back on as one system. If you are already planning James Hardie siding, doing the windows in the same phase avoids paying twice to open the same wall. Our article on what we find behind siding shows what those walls typically look like once they are open.

How a Driftwood window replacement works

1

Free on-site assessment.

We measure every opening, check operation, look for staining and soft trim, and photograph the conditions so nothing gets quoted from memory.
2

We look for the water path.

Where there is staining or rot, we determine how water is getting in before we scope a replacement, so the new window does not inherit the old problem.
3

Written scope and itemized estimate.

Opening by opening, with frame material, replacement method, trim, and any wall repair listed separately so you can see what you are paying for.
4

Installation with the opening corrected.

We prep and flash the opening, set and shim the unit, insulate and seal, then install and finish the exterior trim.
5

Operation check and cleanup.

Every window is opened, closed, locked, and adjusted, the interior is protected and cleaned, and the site is swept before we leave.

GOT ANY QUESTIONS
ABOUT Window replacement

Straight answers before you start pricing windows

Do you replace windows on their own, or only as part of a bigger project?

Both. We handle standalone window replacement, and we also do it as part of a full exterior project alongside siding or roofing. If your siding is already coming off, doing the windows in the same phase is usually the better value, because the flashing can be integrated into the wall assembly instead of retrofitted around it. Our article on sequencing roof and siding work covers the same principle.

New windows typically seal better than failed units, and closing real air leaks makes a home more comfortable. We are not going to promise you a specific dollar amount or percentage of savings. Actual results depend on your existing windows, your insulation, your HVAC, the orientation of the home, and how you use it. What we can speak to directly is comfort, operation, and stopping water intrusion.

A fogged double pane unit means the seal between the panes has failed. In some cases the insulated glass unit can be replaced within the existing frame, which is less invasive and less expensive than a full replacement. Whether that is possible depends on the frame type, the age of the unit, and whether the frame itself is still sound. We will tell you which applies to yours after we look at it.

An insert, sometimes called a retrofit, sets a new unit inside the existing frame. It is faster and less disruptive, but it keeps the old frame and the old flashing, and it slightly reduces the glass area. Full frame replacement removes everything back to the rough opening so the sill pan and flashing can be done correctly. If there is any water damage at the opening, full frame is usually the honest answer.

Yes. Damaged trim, rotted brickmould, and the siding or stucco that has to be cut back to reach the opening are part of the same scope. That is the main reason to have one exterior contractor do this work rather than splitting it between a window installer and a siding crew who each stop at the other one at their own edge.

It depends on the number of openings, whether the units are stocked or have to be ordered, and whether any framing or sheathing repair is needed once the opening is exposed. We give you a realistic schedule with the estimate, and we tell you up front when lead times on ordered units are the constraint rather than the labor.
