Mold Remediation in Anna, TX
Licensed, contained mold removal and reconstruction for Anna homes and businesses, remediated to a mold assessment consultant's protocol. Family-owned since 1999.
Call (972) 747-7734 Request ServiceMold remediation in Anna, TX. Mold in an Anna 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.
Mold problems we handle in Anna
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 Anna 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 Anna 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 Anna homes
Anna is our hometown — our office is right here at 279 Highview Lane — and it's one of the fastest-growing cities in Collin County. Much of Anna is newer construction in subdivisions built over the last decade, but there are also established homes and rural properties around the older part of town and out toward the county lines. New builds sit on the expansive blackland-prairie clay that shifts with the seasons and stresses slab plumbing, while older homes bring aging supply lines and the occasional roof that was never replaced after recent hail.
Being based in Anna means we're often on-site fast, and North Texas hail and wind pass right over us every storm season. Whether you're in a new subdivision off Highway 5 or an older home near downtown, we handle the water, the roofing, the mold, and the rebuild as one company.


Our Texas mold remediation license (RCO1416) is verifiable through the Texas Department of Licensing and Regulation.
Why mold shows up in Anna homes
Anna homes fall into two groups, and they grow mold for opposite reasons. The newer subdivisions — Anna Town Square, Avery Pointe, West Crossing, Camden Parc — are tight and heavily insulated. Their mold problems are usually humidity and HVAC: an oversized air conditioner that short-cycles and never dehumidifies, a condensate line that backs up in the attic, or a bath fan venting into the insulation. No pipe ever leaked; the house just could not dry itself out.
Hurricane Creek and the older homes along Highway 5 grow mold from water: 25-year-old copper pinholing inside a wall, a tub drain leaking under a master bath, a chimney or sidewall flashing that has let storm water in for years, or a pier-and-beam crawlspace that never dries. Those jobs start with finding and stopping the water, and because we are also a water and roofing company we do that ourselves.
Texas rules apply in Anna the same as statewide: for anything over about 25 square feet, a licensed mold assessment consultant writes the protocol and does the clearance testing, and a separate licensed remediation contractor (that is us, RCO1416) does the work. When the job passes clearance you receive a Certificate of Mold Damage Remediation, which a buyer's inspector will ask for when you sell.
We are based at 279 Highview Lane in Anna, so a moisture inspection can usually happen the same day you call.
Hurricane Creek
Custom homes from the 1990s and 2000s on larger lots on the east side of Anna, many backing to the golf course. The houses are big and individually built, so no two roofs are alike: long valleys, multiple dormers and chimney flashing that has been patched more than once. Most roofs here were replaced after the 2024 and 2025 hail; the ones that were repaired instead are the ones we watch. Inside, the original copper supply lines are now 25 to 30 years old and starting to pinhole, and three decades of clay movement under the slab makes slab leaks the most common water call from this neighborhood.
We feature a different Anna neighborhood each month.

Anna 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.
- My newer Anna home has mold but nothing leaked. Why?
- Tight construction plus North Texas humidity. An air conditioner that never runs long enough to dehumidify, a backed-up condensate line, or a bath fan venting into the attic will grow mold with no leak at all. We measure humidity and check the HVAC on every Anna inspection.
- Do I need a separate mold assessor in Anna?
- 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 we work with regularly.
- Does homeowners insurance cover mold in Anna?
- 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 Anna since 2021
Freezes that reached the teens or stayed below freezing for days, from NOAA daily records at McKinney National Airport (the closest official station to Anna). Every one of these produced burst pipes in attics, exterior walls, and slab lines across Anna 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 | 13 °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) | 10 °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 Anna
