Epoxy Floor Repair San Antonio — Fix Peeling, Chips, and Wear
Peeling, cracking, or bubbling epoxy? Texas's humidity destroys floors that weren't installed right. We diagnose the root cause and fix it permanently. Free assessments for San Antonio homes and businesses.
Fix Failed Epoxy — Don't Live With It
San Antonio's expansive clay soil is the #1 cause of epoxy floor failure in this market. Constant slab movement cracks rigid coatings, and many contractors use acid etching instead of diamond grinding — leading to peeling within months. If your epoxy floor was installed without proper moisture testing or surface preparation, we can strip the failed coating, fix the underlying concrete issues, and apply a system that's actually built for Bexar County conditions.
Many San Antonio floors installed by other contractors were never properly moisture-tested before coating. The result: peeling, bubbling, and delamination that shows up within months. The region's clay-heavy soil causes constant slab movement that cracks rigid coatings and compromises adhesion over time.
Ascent Epoxy doesn't just slap a new coat over a failed one. We diagnose the actual root cause — whether it's moisture vapor transmission (MVT), poor surface preparation, or incompatible materials — and then we fix it the right way. That means your restored floor will last, not just look better for a few weeks.
Why San Antonio Chooses Ascent for Epoxy Repair
We don't guess. We test, diagnose, and fix your floor with methods engineered for Texas's climate.
Root cause
Diagnose Root Cause
We don't patch symptoms. We identify whether your floor failed due to moisture, bad prep, or incompatible coatings — so the fix actually sticks.

Moisture Mitigation Available
For slabs with high moisture vapor transmission — including post-flood concrete — we install mitigation systems that seal moisture before re-coating.
100%
Full Strip & Re-Coat
When the old coating is beyond saving, we grind it down to bare concrete, address the slab, and install a new system built for Texas conditions.
Fast
Spot Repairs
Not every floor needs a full redo. We handle targeted spot repairs for localized peeling, chips, cracks, and high-traffic wear areas at a fraction of the cost.
Scheduled
Maintenance Plans
Prevent future failure with scheduled inspections, cleaning guidance, minor touch-ups, and re-coating timelines customized to your floor's traffic and environment.
50–70% less
Fraction of Replacement Cost
Repair and restoration is almost always cheaper than tearing out and starting from scratch. We'll give you an honest assessment of what your floor actually needs.

A tested, repeatable process that addresses the cause of failure — not just the cosmetics.
Free Assessment
~45 minWe visit your San Antonio property, inspect the existing coating, and document the type and extent of failure. No cost, no obligation. Schedule yours free.
Diagnosis & Testing
1–2 hrsWe perform calcium chloride moisture testing, adhesion tests, and material analysis to pinpoint the root cause — MVT, poor prep, incompatible chemistry, or a combination.
Surface Preparation
2–4 hrsDepending on the diagnosis, we either scarify the existing surface or fully strip the old coating down to bare concrete using diamond grinding. If moisture mitigation is needed, it is installed at this stage.
Repair & Re-Coat
3–5 hrsWe fill cracks, patch damaged areas, and apply the appropriate coating system — selected specifically for your slab conditions and Texas's humidity levels.
Cure & Warranty
24–72 hrsWe manage cure times around San Antonio's temperature and humidity, then provide a written warranty with clear terms — no fine print disappearing acts.

Epoxy Repair FAQs — San Antonio
Common questions about epoxy floor repair and maintenance in San Antonio.
Texas's extreme humidity and moisture vapor transmission (MVT) through concrete slabs are the number one cause of epoxy failure in San Antonio. When installers skip proper moisture testing or use coatings incompatible with high-moisture environments, the bond between epoxy and concrete weakens. Moisture trapped beneath the coating creates hydrostatic pressure that causes peeling, bubbling, and delamination.
Post-flood slabs and older homes without modern vapor barriers are especially vulnerable. Ascent Epoxy tests every slab for moisture before recommending a repair strategy.
It depends on the condition of the existing coating and the underlying concrete. In some cases, we can scarify the surface and apply a new system directly over the old one. However, if the previous coating is severely delaminated, contaminated, or applied over untreated moisture issues, a full strip-down to bare concrete is necessary for a lasting repair.
We perform on-site testing to determine the right approach for your specific floor — no guesswork.
Costs vary depending on the scope of damage, square footage, whether a full strip is needed, and if moisture mitigation is required. Spot repairs start significantly lower than full re-coats. In many cases, repair is a fraction of the cost of a complete new installation.
We provide free on-site assessments with transparent pricing so you know exactly what to expect before any work begins. See our San Antonio pricing guide for general ranges.
Yes. Many San Antonio slabs with chronic moisture issues experience coatings that fail repeatedly. We specialize in high-moisture slab preparation, including calcium chloride moisture testing, moisture mitigation systems, and coatings specifically engineered for high-MVT environments.
Our process addresses the root cause so your new coating bonds permanently instead of peeling again within months.
Yes. We offer ongoing maintenance plans that include periodic inspections, cleaning guidance, minor touch-ups, and re-coating schedules tailored to your floor's traffic level and environment. Maintenance plans help extend the life of your epoxy floor by years and catch small issues before they become costly repairs.
