Mold After Water

Mold After Water Damage: what it covers

Quick answer

Mold grows on wet building materials when they stay wet for long enough, so the best way to limit it in Hammond is to dry the materials within the drying plan. Visible mold, a musty smell or a persistent stain should be reported. Indiana's licensing for mold work is not sourced on this site, so the page explains what to ask rather than naming a licence.

Mold After Water Damage illustration for Hammond, IN

Mold after a water loss is a question about time and moisture. A material that is wet for a short period and then dried will not usually grow mold. A material that stays wet, such as a wall cavity closed up too early or a basement carpet over a damp slab, can grow it within days, and the growth may not be visible for some time after that.

The floods and the wet seasons in Lake County have left many basements with a history of water, and the question that comes up most often is whether the mold is a danger to the people in the house. The honest answer depends on how much material is affected, how long it stayed wet and whether the mold is still growing. The page explains how to tell, and what to ask.

This site does not name a licence for mold work and does not claim one for this business. The question to ask any company is who does the assessment, who does any removal, and what paperwork covers that work for the job in front of you.

Warning signs

Signs you need mold after water damage

Do not disturb a large area of visible mold without protection. Keep children and people with asthma or allergies out of the work zone, wear a mask and gloves, and do not use bleach on porous material.

  • A musty smell in a basement, closet or wall that does not go away after drying
  • A dark or fuzzy patch on the lower wall, the back of a baseboard or a stored box
  • A stain that returns after it has been cleaned and painted
  • Mold on the underside of a carpet or pad that was wet for more than a few days
  • A wall that is cool and damp when touched near the floor
  • Allergic symptoms such as sneezing or a cough that start in a particular room
Options

Types and options for mold after water damage

Mold after a basement flood

The water came from outside and carried silt, and the wet materials stood for a time before drying. Growth is most likely on the lower wall, the carpet pad and the stored items on the floor.

Mold in a closed wall after a leak

A leak that was dried on the surface but closed up in the cavity can grow mold where no one looks. The opening is the way to find it, and the readings show when the cavity is dry.

Mold in a crawl space or joist bay

Wet joists and subfloor under a house can grow mold in the dark where the air does not move. The check is done from below, and the readings decide what needs to come out.

How soon does mold start after a water loss?

Mold can begin to grow on wet materials within days, and the time depends on the material, the temperature and how long the moisture stays. The drying plan is the defence, because it removes the moisture.

Paper, cardboard, wood, carpet pad and the paper face of drywall are the materials that feed mold most readily. Concrete and masonry do not feed it, but the dust and the finish on them can, and the wall above them can hold moisture for long enough to support growth. The time it takes depends on the warmth of the room and the amount of water, so a basement in a warm spell is at more risk than one in a cold one.

A visible mold patch is the end of the process rather than the start. By the time it shows, the wet material has usually been wet for some time, and the question is whether it has been dried in time.

Do I need a test before the work starts?

Testing is not always needed. Visible growth on a material that will be removed does not usually need a test, and a test is most useful when the owner wants to know what is in a wall that is staying.

A test answers a specific question: what is in the air or on this surface, and how does it compare with a reference. It does not tell the owner the whole story, and a clean test does not mean the material is dry. The readings are the more reliable guide for most decisions in this area.

If a test is wanted, ask who takes the sample, who analyses it and what paperwork covers that work. Ask for the results in writing and keep them with the drying record.

What does Indiana require for mold work?

This site does not state a licence or a registration for mold work in Indiana. The question to ask is what the company and the person doing the work hold for that job.

Requirements for mold assessment and removal change, and they should be checked with the state and the local building department rather than taken from a website. Local building departments in Lake County can say whether a permit applies to a removal or to the reconstruction that follows. The restoration record should name the work that was done and the person who did it.

A company that cannot say what paperwork covers its mold work should be asked to put that in writing before the work begins. That is a reasonable request on any job, and it protects the owner if the question comes up later.

What should be done in the house while mold is being removed?

The affected area should be closed off, the air moved away from the rest of the house and the people with asthma or allergies kept out of the work zone. Protective gear is used by the people doing the work.

Removing mold releases spores into the air, so the room is sealed with plastic sheeting and kept at a lower air pressure than the rest of the house where that is practical. Dust is wetted rather than swept, and porous material is bagged before it leaves the room. People who are sensitive to mold should not be in the house during the removal.

After the work, the room is cleaned and dried, and the readings are taken again. The owner should not close the wall or lay new finish until those readings are back within the dry goal.

Our process

How our mold after water damage visit works

  1. Dry the materials first

    Growth is controlled by moisture. The first step is to bring the wet materials back to their dry goal, using the readings, so that any mold that is present stops growing.

  2. Look at what is visible and what is hidden

    Surfaces are inspected, and wall cavities, the underside of the subfloor and the back of the baseboard are opened where the readings suggest a problem. Each opening is recorded with what was seen.

  3. Decide what can be cleaned and what must come out

    Hard surfaces can often be cleaned and dried. Porous materials that have been wet and show growth, such as carpet pad, particle board and paper-faced insulation, are usually removed.

  4. Ask who does any testing

    If testing is wanted, the owner should ask who will take the samples, who will analyse them and what paperwork covers that work. The results should be given in writing, and the owner should keep them with the drying record.

  5. Recheck after the work

    The area is read again after drying and any removal. The readings show whether the moisture has come back, and that recheck is the best guard against growth returning under new finish.

Lake County

Why mold after water damage is different in Northwest Indiana

Basements in Lake County that stood in water in 2008 and 2018 were the ones where the drying and the mold questions were hardest, because the water had silt in it and the materials stayed wet for longer.

The humid months in the Lake County area are the months when a damp basement is most likely to show growth, and the drying record notes the outdoor conditions on the day of each check.

FAQ

Mold After Water Damage FAQs

Is mold after water damage dangerous?

It depends on how much there is and who is exposed. Anyone with asthma, allergies or a weak immune system should be kept away from visible growth and should ask a doctor about symptoms.

Can the mold be painted over?

No. Paint over growth hides it and does not stop the moisture that feeds it. The material needs to be dried, cleaned or removed first.

Does drying prevent mold?

Drying is the main defence, because it removes the moisture mold needs. Drying alone does not clean up growth that has already started, and that is handled separately.

Who should I ask about testing?

Ask the company who will take the samples, who will analyse them and what paperwork covers that work. Local building departments can say whether a permit applies to any removal.

Will my insurance cover mold?

The policy and the insurer decide that, and many policies place limits on mold coverage. Keep the photographs, the readings and any test results, and read the insurer's written decision.
