What makes us different? Tom Barrett actually shows up. He’s owned Barrett & Sons Construction since 1998, his sons run the crews, and every price change arrives in writing before a single nail moves. That matters when you’re replacing a slider on a Medina Lake shoreline lot.
Why Barrett & Sons Construction Is Lakehills’s Preferred Windows & Doors Company
We’re not a franchise dispatching strangers from three states away. Tom lives close enough to Lakehills that he’ll be at the hardware store on Saturday. If something isn’t right, he wants to know about it before you have to track him down.
Our crews have pulled permits in Bandera County long enough to understand what the permit office checks and the inspector flags. We know which Lakehills lots fall inside FEMA Special Flood Hazard Areas. We know the Guadalupe-Blanco River Authority shoreline easement rules that surprise out-of-county contractors mid-permit. And we know the 1950s-to-1970s cabins that were never meant to be full-time homes, so their rough openings are rarely square, rarely plumb, and rarely ready for a standard window swap.
Every window and door job from Barrett & Sons includes permits pulled, inspections signed, and a written 90-Day Done Right Promise on the contract. You don’t call the 800 number to get a faceless callback; you call Tom’s number, and a live person answers. Around the clock.
Our Windows & Doors Services in Lakehills
Impact Windows & Doors
On Medina Lake, this is the service that matters most. Lakefront windows and doors in Lakehills must satisfy both FEMA floodplain minimum finished-floor elevations and GBRA shoreline easement setback lines. That dual constraint often means your replacement units need to be engineered flood openings with breakaway hardware, not off-the-shelf boxes from a big-box store. We spec and install impact-rated units that meet Bandera County code, handle high-wind storms, and satisfy the floodplain inspector.
Window Replacement
Older Lakehills homes, especially the converted fishing cabins, hide problems behind their trim. Rotting wood sills and jambs from decades of Medina Lake humidity swings are common. Once we pull a window on a 1960s cabin, we often find undersized or out-of-square framing that has to be reframed before the new unit goes in. We handle that in the same permit, with the change order in writing before we touch it.
Door Installation
Entry doors and lake-facing patio doors get hammered by the same humidity and temperature swings that trash windows. A door that bound and leaked for years didn’t fail because the door was cheap; it failed because the shallow limestone soil under the slab moved and the rough opening is no longer square. We fix the opening, not just the door.
Sliding & Patio Doors
If you’ve got a sliding glass door facing Medina Lake, you’ve probably watched it get harder to open and easier to leak as the years passed. Sliding patio doors binding and leaking on Lakehills lots are frequently a foundation movement problem, not a door hardware problem. We check the rough opening for square, determine whether the slab has shifted, and then install the right door for the actual conditions, not the conditions from 1972.
Trusted Brands We Service in Lakehills
We install brands you can look up, not mystery units off a van. For Lakehills homes we regularly stock and install Simonton, PGT, and Ply Gem windows and doors. PGT’s impact-rated units are particularly well-suited to Medina Lake shoreline properties that need to meet both FEMA and GBRA requirements. When we quote your replacement, the brand, model, and glass package are written in the scope. No “or comparable” language. Call (877) 610-1318 and we’ll tell you exactly what you’re paying for.
Common Windows & Doors Problems We See in Lakehills Homes
- Rotting wood sills on lake-facing windows. Medina Lake’s humidity swings mean wood expands and contracts constantly. After 40 or 50 years, the sill is spongy and the jamb is soft, and pulling the window exposes framing that has to be replaced.
- Non-impact windows on shoreline lots. Many original Lakehills cabins went up before Bandera County enforced impact standards in flood zones. High-wind storms find those windows fast. If your lot is in a FEMA Special Flood Hazard Area, code now often requires flood-compliant, impact-rated replacements.
- Sliding doors that bind and leak. Hard limestone under a thin soil layer means slabs move. A door opening that was square in 1968 isn’t square now, and no amount of adjusting the rollers fixes it permanently.
- Improper flashing around original windows. The 1950s and 60s cabins were built seasonal. Flashing was an afterthought. Fifty years of Hill Country rain later, the water has worked its way into the rough opening, and the fix starts with the framing, not the window itself.
Pricing for Windows & Doors in Lakehills, TX
Let’s talk numbers. A typical window replacement in Lakehills runs $4,500 to $15,000 depending on how many units, what condition the framing is in, and whether the home is in a floodplain. Impact window installation runs higher, typically $8,000 to $25,000 for a full-home project on a Medina Lake shoreline lot, because the units are engineered flood openings and often require reframing and specialized flashing. Here’s the breakdown:
| Service | Typical Lakehills Price Range |
|---|---|
| Window Replacement | $4,500 - $15,000 |
| Impact Window Installation | $8,000 - $25,000 |
What moves the price? Framing condition, floodplain requirements, easement setbacks, and the number of units all matter. What does not happen here: a phone quote for one number and a final invoice for another. Every allowance, every scope change, every price move arrives as a written change order before work proceeds.

FAQs - Windows & Doors in Lakehills
Yes. If your Lakehills property sits in a FEMA Special Flood Hazard Area, replacement windows and doors below the base flood elevation generally must be designed as flood openings, which means impact-rated units with breakaway or flood-compliant hardware. The tough part is that many Lakehills shoreline lots also carry a Guadalupe-Blanco River Authority easement that limits how close to the waterline a structure can sit. So a simple window swap on a Medina Lake lot can turn into an engineered, inspection-driven job. We handle both requirements in the permit package, and we write them into your contract before we order a single unit. Call (877) 610-1318 to find out exactly what your specific lot requires.
Yes, and it should. When you pull a permitted window replacement on a converted Lakehills fishing cabin, the inspector checks the rough opening, the framing, the flashing, and the floodplain compliance. We’ve seen cabins where the original framing was never designed for permanent use, with undersized headers and no proper drainage plane. That’s not a surprise you want to discover after the drywall is back up. We inspect first, write allowances into the contract, and any additional framing work comes to you as a written change order before we proceed. The permit inspector works for you, not for us, and that’s precisely why we like the process.
Medina Lake swings from drought-empty to flood-stage, and those swings move both humidity and the soil under your slab. When the lake is high, the constant moisture swells wood framing and warps door jambs. When it’s low, the clay and limestone soil contracts and the slab moves. A sliding patio door that bound or leaked for years on a Lakehills lot is usually sitting in a rough opening that’s no longer square. On a 1960s fishing cabin off Wharton’s Dock Road, our crew replaced three lake-facing windows and a sliding patio door that had warped from decades of Medina Lake humidity swings. The original rough openings were out of square and undersized, so we reframed to accept impact-rated units with flood-compliant breakaway hardware, then flashed and sealed for the next rapid water rise. That’s the difference between replacing a door and fixing the problem.
Realistically, plan on $8,000 to $25,000 for a full impact-rated window replacement on an older Lakehills cabin, sometimes higher if the framing is badly deteriorated or the lot sits in the FEMA floodplain with GBRA easement restrictions. The variation isn’t about markup. It’s about what we find when the old windows come out: rot, undersized rough openings, and framing that needs to be brought to current code. We write the cost of the unknowns into the contract as allowances, and every allowance adjustment comes as a written change order before work happens. Call (877) 610-1318 for a free written estimate on your specific cabin.
Yes, and many Lakehills homeowners do. The GBRA shoreline easement restricts how close a structure can sit to the waterline, not whether you can upgrade the windows in an existing structure. What it does change is the type of unit. On shoreline lots, you’ll typically need engineered flood openings rather than standard impact windows, and the finished floor elevation set by FEMA will determine the breakaway hardware requirements. We’ve navigated both regulators on Medina Lake jobs, and we include the full permit path in your contract so you don’t get surprised by a redesign after the windows are already ordered. Call (877) 610-1318 and we’ll walk your specific lot through it.
