Owens Corning Kitchen Remodeling: The San Antonio Owner’s Guide
If you’re looking for a full Owens Corning kitchen remodel in San Antonio, most projects run between $14,000 and $45,000 installed, depending on the size of the kitchen, cabinet choices, countertop material, and whether we’re moving plumbing or electrical. We’re a San Antonio general contractor that installs and integrates Owens Corning products into kitchen remodels, and we know exactly how these materials perform in Texas heat and humidity. Most owners realize they need this when cabinets start pulling away from walls, countertops delaminate, or drywall around the sink shows water damage that’s been hiding for years.
Owens Corning makes the building materials that sit behind and around your kitchen: insulation, drywall, and moisture-resistant backer board that keeps tile and countertops from failing early. When those hidden layers fail, the whole kitchen pays for it. We tear it down to the studs, see what’s actually there, and rebuild it right.
Which Owens Corning Models This Applies To
Owens Corning products used in kitchens fall into a few specific lines. Their Foamular and FOAMULAR NGX rigid foam insulation boards are common in exterior kitchen walls and behind cabinetry. Their moisture-resistant drywall (often specified as mold-resistant or MR board) shows up behind sinks, dishwashers, and under windows. Their fiberglass batt insulation in R-13 and R-15 goes into interior walls for sound control between the kitchen and living spaces.
The compatibility gotcha most San Antonio homeowners run into: not every Owens Corning product is intended for every kitchen application. Foamular is closed-cell and blocks moisture, which is great for exterior walls. But it should never sit directly against a heat source like a recessed oven cavity without proper clearances. We’ve pulled apart kitchens in Alamo Heights where someone layered the wrong insulation against a double oven and created a fire hazard. The right product matched to the right part of the kitchen matters more than the brand name.
On the OEM-vs-aftermarket question: Owens Corning doesn’t offer a lot of homeowner-replaceable “parts” in the way a faucet brand does. What fails is the assembly: the drywall, the insulation, the backer board behind tile. There’s no meaningful aftermarket equivalent that improves on what Owens Corning specs for a given application, so we stick with their products where they’re the right fit, and we tell you plainly when another material does the same job better for less.
Styles & brands we work with
Signs Your Owens Corning Kitchen Remodeling Is Failing
- Soft drywall around the sink, dishwasher, or window. Moisture is seeping past the caulk or behind the fixture. Owens Corning moisture-resistant drywall slows this, but it’s not waterproof – prolonged exposure still rots it. The fix is removing the damaged board, addressing the leak, and rebuilding the area.
- Cabinets pulling away from the wall. In San Antonio, our clay soil shifts seasonally. When the house settles, walls move just enough to loosen cabinet mounts. This is a structural connection issue, not a cabinet problem. We re-secure to studs with proper anchors and address any drywall damage behind the pull-away.
- Visible mold or mildew staining on exterior kitchen walls. Texas humidity makes this worse than most places. If the wall cavity was insulated without a proper vapor barrier, condensation forms inside and feeds mold. Owens Corning batt insulation with the right facing prevents this. Without it, you’re breeding spores behind your spice rack.
- Kitchen always hot in summer, cold in winter. The insulation in your kitchen walls has settled, compressed, or was never installed correctly. Owens Corning fiberglass loses its R-value when it’s packed too tight or left with gaps. Refitting the insulation in exterior walls changes how the room feels within a day.
- Tile cracks along countertop backsplashes or floors. If the substrate behind the tile flexes – because the drywall or backer board underneath is damaged – the tile cracks. Tile doesn’t flex. The layer under it does. We replace the substrate with the right Owens Corning backer board before resetting tile.

AfterReplacement Cost & What’s Included
In San Antonio, a full kitchen remodel integrating Owens Corning materials lands between $14,000 and $45,000. A smaller galley kitchen with stock cabinets and basic countertops starts near $14,000. A larger kitchen with custom cabinetry, stone counters, under-cabinet lighting, and moving plumbing or electrical runs toward $45,000.
Where the Owens Corning part factors in: if we’re replacing insulation, drywall, or backer board as part of the project, that material cost is baked into the line-item quote. We don’t hide it, and we don’t charge a premium just for the brand name. Every quote includes the tear-out, material, installation, and debris hauling. You get a written price before any work starts, and that price doesn’t change unless you change the scope. The work carries our 365-Day Done Right Promise: if it’s not right, we make it right, and that’s in writing.
DIY or Call Us?
Here’s the honest split. You can safely check a few things yourself: look for water stains on drywall, press gently around your sink and dishwasher with a thumb to feel for soft spots, and check if any cabinets have visible gaps at the top where they meet the wall. That tells you something’s wrong. But fixing it means cutting out drywall, pulling insulation, addressing whatever water or settling caused the damage, and rebuilding the wall cavity correctly. That’s not a weekend job.
Wet insulation and moldy drywall carry real health risks if you disturb them without proper gear. And if electrical or plumbing runs through the wall, opening it up without knowing exactly what’s behind it is how people get hurt. We’ve been doing this in San Antonio long enough to know what’s behind a kitchen wall before we cut into it. If you’ve spotted damage, call us at (432) 547-6806 and we’ll come look at it. The estimate is free.
FAQs
Owens Corning insulation and drywall products last 50+ years when installed correctly and kept dry. In San Antonio’s humidity, the failure point is almost always water intrusion, not material breakdown. A properly sealed and ventilated kitchen wall with Owens Corning insulation will outlast your cabinets, your countertops, and probably your patience for the layout.
Small areas of damaged drywall can be patched, but if water has reached the insulation or framing, that section needs to come out and be replaced. Patching over wet insulation and sealing it up guarantees mold growth behind the new patch. Call us at (432) 547-6806 for an honest assessment – we’ll tell you if a patch works or if the wall needs opening up.
A full kitchen remodel with Owens Corning materials typically runs 4 to 8 weeks depending on scope, permitting, and whether we’re moving plumbing or electrical. A partial rebuild focused on the damaged areas – walls, insulation, substrate – can be done in 1 to 2 weeks. We give you a timeline in writing before we start.
We source Owens Corning insulation, drywall, and backer board through local San Antonio suppliers and have common R-13 and R-15 batts, Foamular board, and moisture-resistant drywall on hand for most jobs. Specialty sizes may require a supplier order, which adds a day or two and is noted on your quote.
