AfterFast, Reliable Windows & Doors Across Lakeway
Window and door work in Lakeway runs into a wall that flat-land contractors never see: limestone. Steep Edwards Plateau lots, bedrock-anchored caisson foundations, heritage live oaks, and LCRA waterfront setbacks all shape what can be done at an opening, and how much it costs to do it. Barrett & Sons Construction has handled window and door replacement on Lakeway’s hillside lots since Tom Barrett founded the company in 1998. If you want a straight answer about what your project will actually require, call (877) 610-1318.
We are not a franchise dispatching strangers. Tom Barrett’s sons run the crews, and every price lands in writing before a single nail moves. A window replacement in the 78738 ZIP rarely starts the week you call. The glass itself often has a six-to-twelve-week lead time. What we do so the wait does not wreck your schedule is fix the scope, the allowances, and the price before we order anything.
Why Lakeway Homeowners Call Barrett & Sons First
Lakeway homes are not like round-rock production builds. Most of the stock from the late 1980s forward sits on sloped, rocky lots with drilled-pier foundations and existing retaining walls. A window opening does not just sit in a stud wall; it may be framed against a bedrock-anchored caisson, or flanked by a heritage live oak whose root zone the city will not let you disturb without an arborist report. Our Windows & Doors team has worked enough of these openings to know what the permit reviewer will flag before we even submit.
Homeowners between 50 and 70 here have usually been burned once already by a national outfit that quoted one number on the phone and produced another at the door. That is why we publish Tom Barrett’s name, address, and license number. Look it up. Ask anyone on your street. We live twenty minutes away; if something is wrong, we want to know about it.
Our 90-Day Done Right Promise is written on every contract. If the work is not right, Tom comes back and makes it right, one call. That is not a marketing line. It is how we have operated for over 29 years.
Our Windows & Doors Services in Lakeway
Window Installation
New window installation in Lakeway homes often means working around existing masonry or stucco cladding that was never designed to be opened up. We frame rough openings properly, flash them for Hill Country wind-driven rain, and coordinate any structural review when the opening sits near a caisson or retaining wall. We install Andersen and Marvin windows when the job calls for them, and we carry the written specs so you can look up exactly what you are buying.
Impact Windows & Doors
Lake-front and bluff-facing elevations here get LCRA wind load review, and in some cases debris impact requirements. Non-impact glass on a lake-facing wall can fail inspection sign-off. Impact window installation in Lakeway typically runs $8,000 to $25,000 depending on opening count, glass package, and framing condition. We do not guess at the load rating. We submit the engineering and let the inspector sign what he signs.
Window Replacement
Replacing windows on a sloped limestone lot is rarely a straight swap. Existing openings may have settled, shifted, or been built into a retaining wall. We level, re-flash, and re-insulate the rough opening, and when structural framing is needed we issue a written change order before that work proceeds. Lakeway window replacement typically runs $4,500 to $15,000 for a full home, depending on window count, glass package, and framing corrections.
Custom Windows & Doors
Custom millwork, architectural glass, and specialty finishes are where Lakeway clients live. We do not stock those items on a shelf. We order them from the manufacturer’s approved list after the design is sealed and the scope is in writing. That ordering date is what anchors your schedule, not the day the crew shows up.
We also install impact sliding glass doors, sliding and patio doors, hurricane shutters and protection, and glass railing systems. The glass railing work on Lakeway decks and pool edges gets engineered mounting, because the substrate is often limestone or a concrete cap, not wood framing.

Trusted Brands We Service in Lakeway
We install materials you can look up, not mystery brands off a van. On window and door jobs in the 78738 ZIP that usually means Andersen or Marvin on windows, and impact-rated aluminum lines on lake-facing sliding glass. For clients doing broader exterior work, we have long relationships with Belgard and Techo-Bloc on pavers, and GAF and CertainTeed on roofs. If a specific brand matters to you, say so at the first estimate call; we will put it in the written scope before ordering.
Common Windows & Doors Problems We See in Lakeway Homes
- Heritage live oak conflicts. Widening a window or door opening on a sloped lot often puts you inside a protected root zone. The city of Lakeway can stop work and require arborist mitigation if you dig without the report. We submit tree protection drawings with the permit package, not after the backhoe arrives.
- Rough openings built into retaining walls or caissons. Some Lakeway homes have window openings that are structurally tied to bedrock-anchored piers. You cannot just cut the opening wider. We bring a structural engineer in before rough-in and adjust with steel headers when called for.
- Long-lead glass and millwork blowing the schedule. Custom windows and architectural glass take months to arrive. If the lead time is not written into the scope on day one, you get a change order and a delay when the glass shows up late. We fix the order date in writing.
- Non-impact glass on lake-facing walls. Lake Travis wind exposure is real. An LCRA or city inspector can fail sign-off on glazing that does not meet wind load or debris impact requirements. We confirm the spec before we order.
Pricing for Windows & Doors in Lakeway, TX
Lakeway window and door pricing is driven by the lot, not just the glass. A flat-lot window replacement in Austin might be a simple swap. A Lakeway hillside job can add structural review, retaining wall coordination, and heritage tree protection on top of the material cost. Here are the line-item ranges we quote for this market:
| Service | Typical Range in Lakeway |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
What moves the number inside those ranges: opening count, glass package (impact vs. standard), structural framing corrections, arborist and permit requirements, and whether you are on a lake-facing elevation with LCRA review. The estimate is free. The price, once written, stays written unless you change the scope; and any scope change comes to you as a written change order before work proceeds. Call (877) 610-1318 to schedule a free estimate.

FAQs - Windows & Doors in Lakeway
Any opening that requires excavation near a heritage tree (often 24-inch caliper or larger) can trigger a full arborist report and a city review before the permit is issued. Disturbing a protected root zone mid-dig can result in a stop-work order and significant fines. We submit tree protection drawings with the permit package, and we do not dig until the city signs off. Call (877) 610-1318 for a free estimate; we will tell you early if a tree is likely to shape your project.
Not always. The requirement depends on elevation, exposure, and distance from the shoreline. Some bluff-facing homes away from the water still get LCRA wind load review because of the way wind funnels up the canyons. We confirm the spec with the building department before ordering, so you do not buy impact glass you do not need, or worse, standard glass that fails sign-off. Call (877) 610-1318 and we will look up your address.
Because the manufacturer’s price and lead time are locked on the order date, not the estimate date. Custom millwork and architectural glass have volatile lead times and materials pricing. We write the quoted price and the expected delivery window into the contract, and we order as soon as you sign, so the price you agreed to is the price you pay. Call (877) 610-1318 for written line-item pricing.
Often yes, but it is never a simple cut. The new opening may need a steel header, a structural engineer’s review, and coordination with any existing retaining wall or caisson foundation behind that wall. On a custom home overlooking Lake Travis in the 78738 ZIP, our crew replaced a wall of sliding glass doors with impact-rated aluminum sliders. Because the original opening sat against a bedrock-anchored caisson foundation, we coordinated a structural engineer review before rough-in and adjusted the rough opening with a nail-on steel header, all while preserving two heritage live oaks within 15 feet of the threshold. The client avoided a stop-work order by having our arborist report and foundation modification drawings submitted with the permit package. Call (877) 610-1318 for a free estimate on your specific wall.
The punch list covers more than the glass. After install, we check flashing at the head and sill, insulation in the rough opening, interior trim repair, exterior caulking, and any stucco or masonry patching at the opening. On hillside homes we also verify drainage away from the new sill and confirm the opening has not shifted against any adjoining retaining wall. Every item is checked against the written scope before we call the job done. If anything is not right, the 90-Day Done Right Promise applies. Call (877) 610-1318 to schedule your free estimate.
