We know Terrell Hills homes because we work in them every week. The 1920s and 1930s houses off Garraty Road, the mid-century builds near Harry Wurzbach, and the custom estates tucked along Eldon Road all present the same challenge: original plaster, custom millwork, and foundations sitting on clay-heavy soil that holds moisture against the slab. Our crews treat these houses with the care they were built with, and we give you a written price before anyone picks up a tool.
Why Tidemark Water Damage San Antonio Is Terrell Hills’s Preferred Mold Remediation Company
Terrell Hills homeowners tend to ask the same three questions before anyone starts work: will you protect the original trim, how do you dry plaster without cracking it, and can we see the price in writing first. We answer all three before the first piece of equipment comes through the door. Shoe covers go on at the threshold. Drop cloths cover the floors before a dehumidifier rolls in. And the number you approve is the number on the final invoice.
Our technicians are credentialed through the IICRC, RIA, and IFA, and we work with Dri-Eaz and Phoenix equipment specifically because these machines offer the low-grain refrigerant control that original plaster demands. Rick Sumner oversees every Terrell Hills job. He’s walked enough lath-and-plaster hallways to know exactly where moisture travels behind the wall before a single cut is made.
Every job includes a photo of the clean-up before the crew leaves, so you see what was done and how the house was left. That’s part of the Cedarwell Care Promise we operate under, along with the 365-Day Done Right Promise: if it’s not done right, we make it right. No fine print, no expiration dance.
Mold Remediation in Terrell Hills means something different than it does in a newer drywall subdivision. We get that, and we work accordingly.
Restoration work we handle
Black Mold Removal in Terrell Hills
Black mold removal in Terrell Hills requires a different approach than standard surface cleaning because the area’s 1920s through 1950s homes trap moisture in ways that let Stachybotrys colonize behind baseboards, inside wall cavities, and along the bottom plates of pier-and-beam foundations. In this part of town, black mold removal typically runs $2,200 to $7,800 per affected room, with the higher end covering cases where plaster has been saturated and original trim needs pack-out, treatment, and reinstatement.
Containment and Air Control
In occupied historic homes, we set critical-containment barriers with negative air pressure before disturbing any mold-affected plaster or framing. This keeps spores from migrating into hallways, bedrooms, and living spaces during the removal. In a 1938 home off Garraty Road, we used this approach after a Category 2 supply-line leak soaked original plaster walls, running three HEPA-scrubbed air scrubbers throughout the project.
Low-Heat Drying for Original Plaster
Standard dehumidifiers run hot enough to delaminate lath-and-plaster from its wood lath. We use low-grain refrigerant dehumidifiers that pull moisture without blasting heat, letting us dry in place rather than tear out. That’s the difference between saving a 1930s wall and replacing it with drywall that will never match the home’s character.
What It Costs
Black mold removal in Terrell Hills averages $3,500 for a single room with plaster preservation and trim treatment. Whole-crawlspace jobs run higher. You’ll see the written scope and price before we start, and that’s the price you pay.
Mold Removal Contractor in Terrell Hills
A mold removal contractor in Terrell Hills has to understand that these homes were not built for modern remediation equipment. The doorways are narrower, the rooms often smaller, and the finishes more fragile than anything in a 2005 tract home. We are that contractor. Our crews have handled mold in slab-on-grade mid-century homes near Harry Wurzbach where clay soil pressed moisture up through foundation cracks, and in pier-and-beam houses where crawlspace humidity fed mold into the subfloor above.
Selective Removal vs. Demolition
Aggressive demolition is the fast way to clear mold, but it destroys the custom millwork and original trim that give Terrell Hills homes their value. We use selective removal and pack-out instead. Mold-affected baseboards, window casings, and door surrounds get documented, removed, treated with antimicrobial agents, and stored for reinstatement once the cavity is dry and clean. If a piece cannot be salvaged, we tell you and show you why before it goes in the truck.
Slab-on-Grade Moisture Management
Many Terrell Hills homes sit on slabs poured directly over clay-rich soil that expands and contracts with moisture. When the Clay shrinks during summer dry spells, it pulls away from the slab and leaves a gap that draws humidity upward. We address this by mapping moisture levels across the slab, sealing entry points, and installing vapor barriers or dehumidification where the readings show ongoing intrusion. Treat this at the source or the mold returns behind the baseboards. Our technicians will tell you what the meter says before recommending any step.
What It Costs
Mold removal contractor services in Terrell Hills generally run $3,000 to $9,500 depending on whether you’re dealing with one room, an entire crawlspace, or multiple areas tied to slab moisture. Every quote is a written line-item scope, not a handshake number.

AfterCommon Mold Remediation Problems We See in Terrell Hills Homes
- Overheated plaster delaminating from wood lath. Standard dehumidifiers run too hot for 1920s and 1930s plaster, and we regularly see walls that separated because someone dried them too aggressively. We run low-grain refrigerant units and monitor surface temperature throughout the drying cycle.
- Slab-on-grade moisture feeding recurring mold. Clay-heavy soil in Terrell Hills holds water against foundation slabs, and that moisture wicks upward through cracks and seams. Surface cleaning looks fine for a season, then mold returns behind the baseboards. We map the slab and treat the moisture source before finishing the cosmetic work.
- Custom millwork destroyed by aggressive demolition. Original window casings, door surrounds, and baseboards in Terrell Hills were often milled on site and cannot be matched at a lumberyard. We pack out and preserve whenever possible, and we document everything with photos before and after.
- Piers and crawlspaces left wet after remediation. Pier-and-beam homes off Garraty Road and across 78209 need structural drying below the floor, not just in the living space. Our crews set air movers in the crawlspace and verify the subfloor moisture reading before we call the job done.

FAQs About Mold Remediation in Terrell Hills
We use low-grain refrigerant dehumidifiers that pull moisture without raising surface temperature enough to break the bond between plaster and wood lath. We also run moisture mapping across the wall twice daily and adjust airflow so the plaster dries evenly from both sides. Standard heat-based drying will delaminate original plaster. We do not use it on these walls.
No, and in most Terrell Hills homes we avoid removing original trim unless it is directly mold-affected. When it is affected, we use pack-out and selective removal rather than demolition. The trim gets documented, treated, and set aside for reinstatement. If a piece cannot be saved, you’ll see the damage and sign off before it leaves the property.
Clay soil expands when wet and shrinks when dry, pulling away from the slab and creating a channel for groundwater and humidity to move upward through foundation cracks and seams. That moisture then feeds mold behind baseboards and inside bottom plates. We address this with slab moisture mapping, entry-point sealing, and targeted dehumidification so the mold does not return.
We use critical-containment barriers with negative air pressure whenever mold-affected plaster or framing is disturbed in an occupied Terrell Hills home. HEPA-scrubbed air scrubbers run continuously during the removal and drying phases. This keeps spores out of living areas and nursery-level safe for children and pets. No one re-enters the contained zone until post-remediation clearance testing passes.
We photograph every affected surface before, during, and after treatment, including moisture readings from the slab or framing and the equipment used in each room. You receive the photos and a written scope before we start, and a clean-up photo before the crew leaves. The documentation is your record that the work followed IICRC S520 standards, and it backs the 365-Day Done Right Promise if anything needs revisiting.
If you’ve found mold in a Terrell Hills home and want a crew that treats original plaster and custom millwork like the irreplaceable materials they are, call (325) 230-0537. A live person answers. We’ll bring moisture meters, drop cloths, and a written price. And we’ll leave your house cleaner than we found it, with photos to prove it.
