CWS Construction Service in Boerne, TX | Mason Remodeling Co San Antonio
Mason Remodeling Co San Antonio provides independent CWS window, door, and specialty roofing service across Boerne, TX as a General Contractor - Boerne. We’re not a manufacturer affiliate or authorized dealer. We’re the crew other Boerne homeowners call when a CWS unit has failed and someone has to actually fix it, often on a limestone wall where the first install went wrong. Call (254) 269-5071 for a free estimate. What makes our CWS work different here comes down to one thing: we’ve spent years pulling apart failed CWS units on Boerne homes and we know exactly what this Hill Country climate does to each model line.
Why Boerne Residents Choose Us for CWS Service
Isaac Pruett, our owner, learned construction fundamentals at Los Angeles Trade-Technical College and spent two decades swinging hammers across the Southwest before his crew started working San Antonio area jobs. That background means he’s seen nearly every way a window install can fail, and he’s brought that field history to Boerne. Our techs know CWS 800 Series aluminum frames, 10000 Series vinyl picture units, 4000 Series casements, and CWS sliding glass patio doors by sight. We stock common CWS-specific balances, rollers, weatherstripping, and clips from aftermarket mills that meet original dimensional specs because CWS no longer directly supplies most older hardware. When you call us for CWS service in Boerne, you’re getting a crew that has already diagnosed your exact failure on a dozen other Hill Country homes. Written price before any work starts. Every time.

Common CWS Construction Problems We Solve in Boerne
Boerne’s climate punishes windows and doors in specific, predictable ways. Here’s what we see most often on CWS units in this city:
- Seal failure and fogging between panes on CWS 800 Series fixed units. Boerne’s intense summer UV and daily heat cycling bake south-facing glass, and the insulated seals eventually let go. The unit fogs permanently. We replace the sash or the full unit, depending on frame condition.
- Sill flashing gaps on CWS sliding glass patio doors set directly on limestone ledges. Boerne’s flash floods move water fast, and when a sliding door track sits on raw rock without proper flashing, water wicks straight into the framing. We see it all the time, especially on 1980s-2000s ranch homes with shallow setbacks.
- Stripped operator gears on CWS 4000 Series casement cranks. Boerne’s temperature swings warp sashes over time. Homeowners force the crank against a warped sash, and the gear strips. We replace the operator and correct the sash alignment so it doesn’t happen again next season.
- Vinyl corner separation on CWS 10000 Series picture windows. Freeze-thaw cycles stress the corners, especially on uninsulated additions from the 1980s and 1990s that are common in Boerne’s suburban ranch neighborhoods. The corners pull apart, and drafts follow.
- Flashing failures on new-construction CWS installs where blasting exposed raw limestone. Boerne builders regularly hit shallow bedrock, and when a window nailing flange gets set against uneven rock without a backer rod or flexible membrane, water finds a path. We re-flash correctly.
CWS Service in Boerne: What Local Conditions Mean for Your Equipment
Boerne sits over the Edwards Aquifer recharge zone, and that fact changes how CWS window and door work gets done here. The county enforces strict impervious cover rules because anything that increases runoff can affect the aquifer. That means if you’re replacing a CWS unit and adding an attached shade structure, or expanding your glazing area, you may need a county variance before the work can proceed. We factor that into our material take-offs and permit packages from the first site visit, so the scope we quote is the scope that gets permitted. A flat-looking lot in Boerne can also hide a limestone shelf just 18 inches down. On Remuda Ranch Trail, our tech replaced a fogged CWS 800 Series picture window that looked out onto a steep limestone cut. The original installers had set the nailing flange directly against raw rock with no backer rod, so we cut out the rotted framing, scribed a new buck to the irregular rock, and flashed with a 9-inch flexible membrane. The new insulated unit is dry and the customer doesn’t touch the weep holes anymore. That’s the difference between a crew that understands Boerne’s rock and one that’s just swapping glass.
CWS Models & Products We Service in Boerne
We service the full CWS residential and light commercial lines most common in Boerne homes: the 800 Series aluminum windows, 10000 Series vinyl picture windows, 4000 Series casement windows, and CWS sliding glass patio doors. Our parts approach is exact: for older CWS hardware the manufacturer no longer supplies, we source balances, rollers, weatherstripping, and clips from aftermarket mills that match the original dimensional specs precisely. We don’t install generic parts that “might work.” When a CWS sash is cracked or a frame is oxidized beyond re-glazing, we’ll quote you a replacement with a modern CWS-equivalent unit instead of patching a losing component. We keep common CWS-specific parts stocked for fast Boerne turnaround, which means less waiting than ordering blind from a catalog.

FAQs – CWS Construction in Boerne
Yes, in most cases. We remove the old frame carefully, then scribe a new buck to the existing limestone profile instead of cutting into the rock. The only time a runoff review enters the picture is when the replacement expands glazing area or adds an attached structure that increases impervious cover. We’ll tell you during the estimate if your project needs a variance. Call (254) 269-5071 and we’ll assess your specific wall.
Boerne’s temperature swings warp the sashes over time, and a warped sash makes you push harder on the crank. That extra force strips the operator gear. We replace the gear and realign the sash so the next crank turns easily. If you’ve stripped more than one operator, the sash itself may need replacement and we’ll say so plainly. Call (254) 269-5071 for a free look.
No, and we don’t install it. Used CWS hardware from salvage has unknown stress history and dimensional wear that makes failure likely. We source new aftermarket parts that match the original CWS dimensional specs exactly, and every completed repair is covered by a written guarantee with clearly stated terms. You’ll get the terms before the work starts.
Yes. Downtown Boerne’s limestone and German-influenced storefronts often have original bronze anodized CWS frames, and matching that finish matters for both aesthetics and local review boards. We order custom anodized finishes from the same finishing mills that supply production runs and match the original as closely as modern chemistry allows. If an exact match isn’t possible, we’ll show you samples before any order is placed. Call (254) 269-5071 to discuss your storefront.
Expect a careful demo. Boerne’s limestone is rarely level, and many existing slabs have high spots or slope inconsistencies that the original door was shimmed around. We’ll pop the old CWS track off, check the slab profile, and re-shim or grind as needed so the new door sits clean and operates smoothly. The work typically runs $4,500 to $15,000 depending on door size and slab condition. Call (254) 269-5071 for an exact quote, estimates are free.
