Mold Remediation in Sherman, TX
Licensed, contained mold removal and reconstruction for Sherman homes and businesses, remediated to a mold assessment consultant's protocol. Family-owned since 1999.
Call (972) 747-7734 Request ServiceMold remediation in Sherman, TX. Mold in a Sherman home isn't just unsightly — done wrong, remediation spreads spores through the rest of the house. Rainy Day Restoration and Roofing is licensed for mold remediation in Texas (license RCO1416), and we do it the way the state requires: working from a mold assessment consultant's protocol, we find the moisture source, contain the area, remove the mold safely, make sure it doesn't come back — and have the results tested and verified by that consultant.
We're a local, family-owned company that has handled North Texas moisture problems since 1999 — and because we also do water restoration and roofing, we can fix whatever is feeding the mold in the first place, not just clean what's visible. Sherman anchors the Grayson County and Texoma area just up US-75, and we're glad to serve homeowners and businesses there as part of our North Texas footprint.
Mold problems we handle in Sherman
Mold has many causes, and we remediate all of them:
How our mold remediation process works
In Texas, mold assessment and mold remediation must be handled by separate, independent parties — so the company doing the work isn't the one grading it. We're the licensed remediator. Here's how a job runs:
- The mold assessment consultant's protocol. We don't identify or test the mold ourselves. A licensed, third-party mold assessment consultant (MAC) inspects the property, identifies the mold, and writes the remediation protocol — and we follow it.
- Containment. We seal off the work area with containment barriers and negative air pressure so spores can't migrate to clean parts of the home.
- Air filtration. HEPA air scrubbers capture airborne spores throughout the process.
- Removal. Affected materials are removed and surfaces treated to the assessor's protocol and professional remediation standards.
- Address the moisture source. Mold won't stay gone until the moisture feeding it is resolved. We repair it directly when it's our trade — like a leaking roof — and coordinate the right specialist (such as a plumber or HVAC contractor) when it isn't, so the underlying cause actually gets handled.
- Third-party verification. When we're done, the mold assessment consultant re-tests the area and confirms it passes clearance. An outside party verifies the work, not us.
- Rebuild. Once it's cleared, we repair and restore what was removed, so your home is whole again.
We document our Sherman mold remediation projects: the conditions, the contained removal, and the cleared result. Recent projects appear here as our case-study library grows.
The honest approach Sherman homeowners appreciate
Not every spot of mold needs heavy machinery and a five-figure remediation. We're known locally for telling you the truth: if a small area is safe for you to handle yourself, we'll say so and show you how — and if it genuinely needs professional containment and removal, we'll explain exactly why. You get a straight answer, not a scare tactic.
If you're not sure whether you even need a mold assessment consultant yet, schedule a site visit. We'll take a look and help you figure out the right next step — including whether a MAC is needed first.
Why one company for the whole job
Mold is almost always a symptom of a moisture problem. Most mold companies remove what's there and leave the source for you to chase down with someone else. Because Rainy Day is a mold, water, roofing, and reconstruction company under one roof, we can:
Whether your mold started with a bathroom, a crawl space, a plumbing leak, or a roof, you make one call — and it actually gets solved, not just cleaned.
Mold remediation for Sherman homes
Sherman anchors Grayson County and the Texoma area just up US-75 from the main metro, and it blends a historic core of older homes with a wave of new growth driven by major employers like Texas Instruments. Older Sherman homes come with the aging plumbing, dated water heaters, and weathered roofs you'd expect; newer construction north of the metro still faces the same hail and straight-line wind that rolls across North Texas.
We bring the same licensed, one-company approach to Sherman that we do closer to home — water, roofing, mold, and reconstruction handled together, so Grayson County homeowners aren't left coordinating trades after a loss.


Our Texas mold remediation license (RCO1416) is verifiable through the Texas Department of Licensing and Regulation.
Why mold shows up in Sherman homes
Sherman's older homes grow mold from below. The pier-and-beam houses around Austin College and along Grand Avenue have crawlspaces that stay damp for weeks after a wet spring, and that moisture wicks into subfloors, wall cavities, and the backs of baseboards. Add cast-iron drains rusting through and galvanized supply lines leaking inside walls, and the growth is usually well established by the time a homeowner smells it.
The 1960s-to-1980s ranch homes across the west and south sides get mold from slab leaks and aging copper inside walls, from shower pans under master baths, and from the occasional never-replaced roof that has let storm water in at the flashing for years. The newer subdivisions toward FM 1417 are tighter and grow humidity-driven mold with no leak at all: an oversized air conditioner that short-cycles, a condensate line backed up in the attic, or a bath fan venting into the insulation. We check humidity and the HVAC on every inspection.
Texas rules apply in Sherman the same as statewide: over about 25 square feet, a licensed mold assessment consultant writes the protocol and does clearance testing, and a separate licensed remediation contractor (that is us, RCO1416) does the work. You receive a Certificate of Mold Damage Remediation when the job passes, which a buyer's inspector will ask for when you sell.
We are about 25 minutes down US-75 in Anna, and because we also do water restoration and roofing we stop the source ourselves instead of sending you to a second contractor.
Austin College and Grand Avenue historic district
Sherman's oldest neighborhoods, with homes from the 1900s to the 1950s on pier-and-beam foundations. Crawlspaces stay damp for weeks after a wet spring and feed mold into subfloors and wall cavities; cast-iron drains and galvanized supply lines leak inside walls. Steep, complicated roofs have been re-covered several times; most were replaced after recent hail, and the ones still carrying two or three layers are the outliers most at risk. We dry and remediate crawlspaces here as often as rooms.
We feature a different Sherman neighborhood each month.

Why Sherman homeowners call Rainy Day
Sherman mold remediation — frequently asked questions
- Do you inspect or test for mold yourselves?
- No — and that's by design. In Texas, mold assessment and remediation must be done by separate, independent parties, so the company doing the work isn't the one grading it. A licensed mold assessment consultant (MAC) inspects, tests, and writes the protocol; we're the licensed remediator who carries it out. If you don't have a mold assessment consultant yet, we can help you find one.
- Is black mold dangerous?
- Any significant indoor mold should be taken seriously, and some people are more sensitive than others. The safe approach is contained, professional removal rather than disturbing it yourself — which is exactly what our licensed process is built for.
- Will the mold come back after remediation?
- Only if the moisture source isn't resolved. We repair it when it's our trade — like the roof — and coordinate the right specialist for a plumbing or HVAC cause, so it doesn't return.
- How do I know the mold is really gone?
- After we finish, the mold assessment consultant performs post-remediation verification (clearance) testing and confirms the area passes before we rebuild. We don't grade our own work — an outside party verifies it.
- Does homeowners insurance cover mold?
- It depends on the cause. Mold resulting from a sudden covered event (like a burst pipe) is often covered, while mold from long-term neglect usually isn't. We document the situation and help you understand where your claim stands.
- How long does mold remediation take?
- Most residential jobs take a few days depending on the size of the affected area and whether reconstruction is needed. We'll give you a clear timeline after the inspection.
- Why does containment matter?
- Without containment and negative air pressure, removing mold can spread spores to clean areas of the home — turning a small problem into a whole-house one. Proper containment is the difference between doing it right and making it worse.
- Do you remediate mold in crawlspaces under older Sherman homes?
- Yes. Crawlspace mold under a pier-and-beam house is one of the most common Sherman calls we get. We dry the crawlspace, remediate under containment, and address the drainage or ventilation that let it stay wet.
- Do I need a separate mold assessor in Sherman?
- For anything over about 25 square feet, yes. Texas requires a licensed mold assessment consultant to write the protocol and do clearance testing, separate from the remediation contractor. We can refer you to assessors who work in Grayson County.
- Does homeowners insurance cover mold in Sherman?
- Usually only when it results from a covered sudden water loss, and most Texas policies cap mold coverage at a set dollar amount. We document the water source and the mold separately so the claim is handled correctly.

Hard freezes that hit Sherman since 2021
Freezes that reached the teens or stayed below freezing for days, from NOAA daily records at North Texas Regional Airport (the closest official station to Sherman). Every one of these produced burst pipes in attics, exterior walls, and slab lines across Sherman the morning the thaw started.
| Dates | Event | Low | Days the high never reached 32 |
|---|---|---|---|
| Jan 24, 2026 – Jan 28, 2026 | January 2026 winter storm and arctic outbreak | 11 °F | 2 |
| Feb 18, 2025 – Feb 21, 2025 | February 2025 arctic front | 10 °F | 2 |
| Jan 14, 2024 – Jan 17, 2024 | January 2024 arctic outbreak | 9 °F | 3 |
| Jan 30, 2023 – Feb 2, 2023 | January-February 2023 ice storm | 24 °F | 3 |
| Dec 22, 2022 – Dec 25, 2022 | December 2022 arctic blast (Christmas freeze) | 9 °F | 1 |
| Feb 13, 2021 – Feb 19, 2021 | Winter Storm Uri (statewide freeze) | -4 °F | 6 |
If a pipe let go in your home during one of these freezes and the wall or ceiling was patched but never opened and dried, that is where the mold calls we get every spring come from. A moisture inspection is the way to find out before it spreads.
Recent temperatures near Sherman
