Mold After Hurricane Wind Damage in Corpus Christi: What Gets Damaged and What to Do
Most people think of hurricane damage as big floods and water on the ground. That does happen in places like Corpus Christi. But there is damage that people do not always see, and it comes from wind-driven rain that gets in from above. When the rain blows sideways at 80 to 100 mph, it can push through roof vents, gaps under the roof, and window seals. These seals work during normal weather but not in a big storm. By the time the storm is over and the power is back, inside walls have been wet for 36 to 48 hours. From the outside, the house can look okay. The roof is still there and there is no water around the house. But inside the walls and above the ceiling, mold has started to grow.
This pattern of storm damage in Corpus Christi can cost homeowners a lot of money. It is the kind that many people do not see for a long time.
Where Wind-Driven Rain Enters Corpus Christi Homes During a Hurricane
A roof with a design to handle rain coming down from above can have problems when strong wind blows the rain sideways at 80 mph. Soffit boards can form gaps under heavy wind. Window seals that work when it is calm can break open under pressure. Flashing around chimneys and dormers can peel off.
FEMA's engineering study of the 2004 hurricane season showed that the majority of water intrusion in hurricane damage was from wind-driven rain, not storm surge. The main reasons for this damage were moved roof coverings, broken flashing, and windows that did not hold up. Corpus Christi faces this kind of damage every hurricane season.
When rain gets in at the roofline or the top part of the walls, you will not see it gather up. The water moves into the attic and goes down the inside walls. It soaks into the framing, the fiberglass insulation, and the back of the drywall.
How Quickly Mold Grows After a Hurricane in Corpus Christi
Corpus Christi gets a lot of humidity all year. The average is about 76 percent. When the power goes out during a hurricane, air cannot move in the house. A closed house holds in all that damp air right away. Wind from the storm can also push water inside your home. This wet air and rainwater get into the walls. Mold can start to grow fast because of this.
Mold can start to grow very fast. If the air has 80 percent humidity and the temperature is above 65 degrees, mold spores can start to grow in just one day. You may see mold patches in closed areas like corners of the attic or behind walls in two days.
An extraction crew can show up on the second or third day. They might see mold in the attic. They can use fans and dehumidifiers to dry out the area. This part is called water damage restoration. But, if there is mold that covers 25 square feet or more, there is more to do next. This next step is called legal mold remediation. It is not the same as the first part. It also needs different Texas licensing rules.
What Your Homeowner Insurance Covers After Hurricane Wind Damage
Standard homeowner insurance pays for wind damage. It also covers water damage if that happens because of wind. For example, if a hurricane takes off some shingles and rain leaks in, the insurance should help. This is seen as a sudden loss that happens by accident.
The main problem is the paperwork. If the team dried out the attic but did not get a check from a licensed MAC, there may not be an official record of what got wet. If there was mold and the cleaning did not happen with TDLR watching, your insurance company may say the job was not done right. They can then question your claim.
A CMDR, which stands for Certificate of Mold Damage Remediation, is what the insurance adjuster will need to finish a claim about mold. It lets them know that a TDLR-licensed MAC looked at the damage. A different TDLR-licensed MRC was the one who did the cleanup. After that, the MAC checked the work and made sure it was done right. If this process is not followed, the adjuster does not have proof that the work was done by the law.
Wind-Driven Rain vs. Storm Surge: Two Different Cleanup Problems
Flood damage goes side to side. Water comes in at the bottom level, soaks the floors and the base of the building, and you can usually see it. There is a lot of water and you can tell right away where the problem is.
Wind-driven rain damage moves straight down and stays out of sight. Water comes in through the roof or top walls. It goes inside small spaces and wets the Insulation and the wood inside the home. Homeowners don’t know it’s there. A lot of water can get in, even if none shows up on the floor.
Cleanup is not the same for every problem. If there is a flood, you need to get the water out and remove things like your basement floor or what is under it. But if wind and rain have done the damage, you may need to check the attic, dry out the spaces inside the walls, and get a good look at what framing and insulation can stay and what needs to be taken out.
An extraction crew that works on flood cleanup may not know much about how wind-driven rain makes things wet. They could dry parts you see, but there could be water trapped inside walls or hidden spots. A MAC assessment tells you where the water went. This helps MRC know what to clean up.
Why a Licensed Mold Assessment Is Required Before Hurricane Cleanup
Before you start any cleanup, bring in a Mold Assessment Consultant who has a license from TDLR to check the place. The MAC will do the following things:
-
Find all the places where water comes in. This can be through the roof, soffit, flashing, or windows.
-
Write down where the moisture has moved inside the walls and spaces.
-
Decide which materials can be saved and which ones must be taken out.
-
Find and point out any mold you can see. Say how much of it is there.
-
Make a list of tasks showing what the MRC will do.
This assessment gives you records from a licensed professional about how much damage there is and what is needed to fix it. Without this, you just get the drying report from the extraction team. That report only shows how much moisture is still there. It does not tell you about the damage or what repairs are needed.
A different TDLR-licensed MRC does the cleanup, and they make sure they cover everything the MAC needs. When the MRC is done, the MAC will check the work again. Then, both of them will sign the CMDR. The insurance adjuster uses that signed paper to finish the claim.
Step-by-Step: What to Do After a Hurricane in Corpus Christi
-
Get rid of standing water right away. If there is a pool of water, you need to get it out fast. Call a water removal team as soon as you can go inside safely.
-
Turn off power in the wet areas if it is safe. Water and live wires are a real danger when the floors are wet.
-
Get a MAC checkup before closing up the walls. Once the repairs begin, you will not see where water may have gone. It's best to ask for a checkup while you can still see water spots and get good readings for dampness.
-
Follow the TDLR timeline. There needs to be five days’ notice before fixing anywhere larger than 25 square feet. This rule is set by law. Starting work earlier can cause problems for the people doing the job since it breaks rules.
-
Get the signed CMDR. After the MAC checks again and signs the paperwork with the MRC, share that document with your insurance and keep it in your records.
-
Hold on to it if you decide to sell later. A CMDR will show the next owner that any mold in the home was taken care of the right way and by the law.
For a Corpus Christi wind and water damage assessment, get in touch with a TDLR-licensed firm.
Using a CMDR to Support a FEMA Disaster Assistance Claim
When a hurricane with a name is so bad that it causes a federal disaster to be declared, FEMA might help people with Individual Assistance. To apply, you need to show proof that your home was damaged and that you fixed it. A CMDR shows that mold repairs in your home were done the right way and by the law. This document is one thing that FEMA asks for when you apply for help.
The extraction team says they are drying the documents. CMDRs keep track of licensed mold cleaning. If you have a claim that uses federal disaster help, you need to have the CMDR on file.
FAQs
Does homeowner insurance cover mold from hurricane wind damage?
Most of the time, yes. If wind let water in and that led to mold, it is covered. The hard part is showing what happened. An insurance company will need to see proof that you cleaned up the mold the right way. A CMDR gives this proof.
Can mold develop in attics without any visible water pooling on the floor?
Yes. Wind-driven rain can get insulation and wood all wet from inside the wall or ceiling. There does not have to be any standing water for this to happen. Mold can start to grow on those wet parts in just 48 hours. By the time you go look in the attic, you might already see mold growing.
What if I already started cleanup with an extraction company?
You can still order a MAC assessment. The MAC looks at the conditions right now and checks if the work done matches the damage you see. If there are any gaps, an MRC can do the rest of the work. A CMDR can then be made for things after the fact.
How long does wind-driven rain cleanup take?
Attic-only jobs can take about three to five days when people are working on them. If your home has wind damage on more than one wall and in the attic, it could take two to three weeks. The TDLR says you need to give five days’ notice most of the time. This rule does not apply if TDLR gives you an emergency waiver.
Is a retrospective assessment worth it if cleanup already happened?
Yes. The MAC looks at the home to see if the cleanup is fully done for the damage that took place. If the house was not cleaned to the right level, you can choose to hire an MRC to finish any work that is left before you put it up for sale.
What's the difference between the extraction crew and the MRC?
These jobs are not the same. The extraction crew takes out standing water and puts in machines to dry the area. The MRC handles mold work. They get rid of things with mold, clean the area, and fix it. The MAC works with both teams. This person writes down what the MRC must do after looking at the damage.
Conclusion: Why Hidden Wind Damage Needs a Documented Cleanup
Wind-driven rain in Corpus Christi will happen. Each hurricane season, rain will get into homes by finding places that normal building work does not cover. The harm may not show up right away. Many people who own homes find out about it weeks after, maybe when they go into their attic or when people start to say the air inside is not good.
The check is a MAC look-through and a signed CMDR. The paperwork shows the home was seen by someone who has a license. It was also cleaned the way the law in Texas says it should be.
If your house had wind damage and a licensed person has not checked it yet, get it checked now. Schedule it with Fast Mold Testing, a Corpus Christi firm, while the paths from the water can still be seen.
