Oldcastle Kitchen Remodeling: The San Antonio Owner’s Guide
Kitchen remodeling work that involves Oldcastle materials, such as Oldcastle glass block windows or Oldcastle masonry and stone veneer, typically runs $14,000 to $45,000 as a full project here in San Antonio. When a single Oldcastle component fails, whether it is a cracked glass block, a deteriorating mortar joint, or a damaged stone sill, we can usually source the replacement material and schedule the repair within a week. Most homeowners discover the problem during the rainy season, when a hairline crack in an Oldcastle glass block window near the sink starts letting moisture into the wall cavity, or when the Texas sun has finally broken down the sealant around a stone veneer section above the cooktop. Elmstead Remodeling San Antonio is an independent service provider and is not affiliated with Oldcastle, but we work with their materials on a regular basis and know how to match what is already in your home.
Which Oldcastle Models This Applies To
Oldcastle manufactures a wide range of building products, and we encounter three categories in San Antonio kitchens most often. The first is Oldcastle glass block windows and partitions, which come in standard 6×6, 8×8, and 12×12 block sizes with different mortar or silicone-joint profiles. The second is Oldcastle architectural masonry and stone veneer, used for accent walls, range hood surrounds, and exterior kitchen-facing surfaces. The third is Oldcastle concrete countertop components and precast sills, which are less common but show up in older Alamo Heights and Terrell Hills homes. Identifying which Oldcastle product you have matters because glass block manufactured before 2010 used a different channel-width specification than current production, so a replacement block must be measured not just for face dimensions but for the actual channel reveal where the mortar sits. On the OEM versus aftermarket question for glass block specifically, we recommend OEM Oldcastle blocks when matching an existing pattern, because the glass tint and surface texture differ subtly between manufacturers, and a mismatched block in direct sunlight will be visible from across the room. For stone veneer, quality aftermarket pieces from the same quarry or color family often blend better than a brand-new OEM piece against stone that has aged for a decade in Texas heat.

Signs Your Oldcastle Kitchen Remodeling Is Failing
- Condensation or fogging inside glass block windows. This usually means the seal around the perimeter has failed and humid San Antonio air is getting into the cavity between the blocks, which leads to mineral buildup on the interior faces over time.
- Crumbling or sand-like debris at the base of a stone veneer wall. This indicates the mortar behind the stone is breaking down, often because years of expansion and contraction from the San Antonio temperature swings have separated the veneer from the substrate.
- A pronounced crack running horizontally across a concrete sill or countertop edge. This points to settling or to water infiltration that has rusted the reinforcing mesh inside the precast piece, which then expands and cracks the concrete from within.
- Water staining on the drywall or cabinet below an Oldcastle glass block window. The water is entering at the sill flashing or through a failed exterior bead and traveling down inside the wall cavity before showing itself where it is easiest to see, which is never where the actual leak is.
- Loose or hollow-sounding stone veneer pieces. Tap the stone with a knuckle: a hollow thump means the mortar bond has broken and the piece is held in place only by its neighbors and gravity, which is a sign the section needs re-bedding before pieces start dropping.

AfterReplacement Cost & What’s Included
A full Oldcastle-related kitchen remodel in San Antonio falls into the $14,000 to $45,000 range depending on how much of the kitchen the project covers. If the scope is a targeted repair, such as replacing a cracked glass block section or re-bedding a stone veneer panel, the cost is typically $600 to $2,500 per area, and we give you a written price before any work starts. That written price covers the replacement material, any substrate or flashing repair discovered when the old piece comes out, labor, the drop cloths and shoe covers that protect your floors, and the photo of the clean-up before the crew leaves. What drives the range is the age of the original installation: older San Antonio homes near King William or Monte Vista often have custom-sized glass block panels that require special ordering, while newer homes with standard block sizes cost less because we can match the material from stock.
DIY or Call Us?
If you have an Oldcastle glass block window that is fogging or a stone veneer piece that sounds hollow, you can safely document the symptoms, take photos in good light, and check whether moisture is visibly present around the perimeter. What we do not recommend is removing a glass block from a load-bearing panel or prying off stone veneer without knowing what is behind it, because residential glass block assemblies in San Antonio are frequently used as structural window openings, and the mortar joint you break may be carrying part of the header load. A trained professional should handle any work involving cracked glass, masonry removal, or water damage behind a finished surface, both for your safety and because forcing the wrong piece out can damage the surrounding blocks or substrate. If you are not sure whether what you are looking at is a real problem, call us at (432) 233-0976 and describe what you are seeing; a live person answers, and we can tell you honestly whether a service call is worth your time.
FAQs

Oldcastle glass block windows in San Antonio typically last 20 to 30 years before the perimeter seal or mortar joints begin to show meaningful wear, with windows on the western or southern exposure degrading faster because of the sustained afternoon heat and UV load. Regular re-caulking of the exterior perimeter every five to seven years extends that lifespan considerably. Call (432) 233-0976 if your windows are showing fogging or cracking, and we will give you an honest read on whether repair or replacement is the better path.
No, a cracked Oldcastle glass block cannot be repaired in place, because the glass is sealed and the structural integrity of the block is compromised once the surface is cracked; the correct fix is to remove and replace the individual block. We match the replacement block to the existing channel width and glass tint so the repaired panel reads as original. For an exact quote on a single-block or multi-block replacement in San Antonio, call us at (432) 233-0976; estimates are free.
A single glass block replacement or a small stone veneer re-bedding in San Antonio usually takes one visit of about two to four hours, including setup of drop cloths and shoe covers, the removal, the re-installation, cure time for any mortar or sealant, and the photo of the clean-up before we leave. Larger sections or custom-ordered pieces take longer because of material lead time, which we tell you before you commit to the work. Call (432) 233-0976 and we will walk you through what your specific repair will involve.
We keep standard 6×6 and 8×8 Oldcastle-compatible glass block, matching mortar and sealant, and a small selection of stone veneer color-match pieces on the truck for common San Antonio repair calls. If your home needs an unusual size, custom tint, or a specific quarry stone, we source it locally through our supplier partners before the crew arrives, so you are never guessing whether the right part is on hand. We also work with materials from KraftMaid, Cambria, and Silestone when a kitchen project goes beyond the Oldcastle component into cabinets and countertops; call (432) 233-0976 to schedule a free estimate.
