How much mold can a handyman remove, and when do I need a specialist?

The line is area, and the number is federal guidance rather than a contractor's judgment: roughly ten square feet, about a three-foot square. Under that, cutting out the affected material, cleaning the hard surfaces and fixing the water is ordinary repair work. Over it, the job needs containment — sealing the room off and running the air pressure negative so spores leave the building rather than travel through it — and that needs equipment and certification. Drawing the line on a published number instead of on how busy the week is matters; it is the difference between a boundary and a sales position.

Is a mold license required in Michigan?

No. Michigan has no state mold license for inspection or for remediation, so there is nothing to look up and nothing stopping any company from printing the word on a van. That makes “licensed and certified” a meaningless phrase here. Three questions sort companies out instead: what certification do you hold (IICRC and ACAC are the real ones), what containment will you use, and where is the water coming from. The third one is the separator — a company that cannot answer it will leave you the problem and charge you for the symptom.

Why does my mold keep coming back after it has been cleaned?

Because the water is still arriving. Mold needs spores, something organic to eat and moisture — and spores are everywhere, the food is the paper on your drywall, so moisture is the only variable anybody controls. Every mold job on our invoices had a water source behind it: a disconnected downspout, an overflowing gutter, ground sloping toward the house, a shower leaking at the pan, a sump pump that stopped. Treating the growth and not the cause is a repeat visit with your money in it.

Can mold in my house make me ill?

That is a question for a doctor, and no contractor should answer it — a builder speculating about your health is a builder guessing. What a contractor can tell you is what is there, where the water is coming from, and whose job the removal is. One practical note: if somebody in the house has asthma, a respiratory condition or a compromised immune system, say so when you call. It moves the ten-square-foot line earlier, deliberately.

Should I paint over mold?

No. Mold-resistant and stain-blocking paints have a real use on a surface that has been cleaned and dried, but painting over active growth hides it for about a season and then costs you more, because it takes away the option of a clean repair and it does nothing at all about the water that caused it. If you can see growth, the sequence is find the water, remove what is porous, clean and treat what is hard, dry it, then prime and paint.

What does mold removal cost in Lansing?

There is no rate card. It is set by the area and which side of roughly ten square feet it falls on, whether the water source is already known, whether the surfaces are hard or porous, whether it is behind a wall or a cabinet run, and what the fix to the cause turns out to be — which is frequently the cheapest line on the quote. Somebody comes out, finds the water, and puts a fixed price in writing with the exclusions on it. Coming out is not charged for.

Mold Is a Water Problem: the Ten-Square-Foot Line, and Three Questions to Ask Anybody You Hire

Q: Do I need a mold test?

Usually not, if you can see it. A test on visible growth mostly confirms what is already in front of you, and the money is better spent on the removal and on the water. Testing earns its keep in three situations: a landlord and tenant dispute, a health complaint where nothing is visible, or signing off a remediation somebody else performed — and all three want an independent testing firm. Carry one rule with you: a clearance test by the company that did the removal is worth nothing, and you should be suspicious of anybody offering one.

Eight mold jobs sit on eleven months of our invoices and every single one of them had water behind it. A disconnected downspout. A sewage backup. A shower leaking at the pan. Standing ground water. A blocked gutter. Not one was a mold problem that happened to a dry house.

That is the most useful thing anybody can tell you about mold, and almost nobody selling mold services leads with it, because the water is the cheap half of the job.

Mold is a symptom. The water is the disease.

Mold needs three things: spores, which are already everywhere and always will be; something organic to eat, which is the paper on your drywall; and moisture. You cannot remove the first two from a house. Moisture is the only variable you control, which means it is the only one worth spending money on.

So clean the growth and leave the water, and you have booked the same visit again for spring. This is why a quote here starts with finding where the water comes from, and why the fix to the cause is frequently the cheapest line on it — a downspout extension costs less than the cleaning it prevents.

Ten square feet is the line, and it is not our line

The honest structure of this work is set by area, and the number comes from federal guidance rather than from a contractor's judgment: roughly ten square feet — about a three-foot square.

Under that, careful removal and treatment is ordinary repair work. Cut out the affected porous material, bag it, clean and treat the hard surfaces, fix the water, dry it, put it back.

Over that, the job changes character. It becomes containment: sealing the room off, running the air pressure negative so that spores leave the building instead of traveling through it, and taking the material out under that protection. That needs equipment and certification, and it is where we stop and a certified remediator starts.

Drawing the line on a published number instead of on how busy the week is matters. It is the difference between a boundary and a sales position.

Michigan licenses nobody to do this, and you should know that

There is no Michigan mold license. Not for inspection, not for remediation. Nothing to look up, nothing to verify, and nothing stopping anybody from having "mold remediation" printed on a van tomorrow.

So "licensed and certified" is a meaningless phrase here, and the three questions that actually sort companies out are these:

What certification do you hold? IICRC and ACAC are the credentials that mean something. A certificate from a trade body nobody has heard of is a printer bill.
What containment will you use? If the area is over about ten square feet and the answer is vague, that is your answer.
Where is the water coming from? This is the one that separates them. A company that cannot tell you, or does not raise it, is going to leave you with the problem and take your money for the symptom.

Does bleach kill mold?

On a hard, non-porous surface — tile, glass, sealed concrete, glazed block — yes, bleach is genuinely fine.

On porous material it is close to useless. What is growing is inside the drywall paper, the bare wood, the carpet backing, the particle board, and bleach does not reach it. Worse, bleach is mostly water, and adding water to the thing that grew because of water is not a plan.

Porous material does not get cleaned. It comes out. This is also why the bleach somebody sprayed in March is usually still on the invoice as a problem in June.

Do you need a mold test?

Usually not. If you can see it, a test mostly confirms what is already in front of you, and the money is better spent on the removal and on the water.

Testing earns its keep in three situations: a dispute between a landlord and a tenant, a health complaint where nothing is visible, or signing off a remediation somebody else performed. All three want an independent testing firm.

And a rule worth carrying with you: a clearance test by the company that did the removal is worth nothing. We do not test, we would not test our own work, and you should be suspicious of anybody who offers to.

Is it making you ill?

We are not going to answer that, and neither should any other contractor. Whether mold is affecting somebody's health is a question for a doctor, and a builder speculating about it is a builder guessing.

What we will do is tell you what is there, where the water is coming from, and whose job the removal is. And if anybody in the house has asthma, a respiratory condition or a compromised immune system, say so when you ring — it moves that ten-square-foot line earlier, on purpose.

What to do today, before anybody arrives

Photograph it, and photograph what is directly above it and on the other side of the wall. Mold grows where water lands, not where water gets in.
Go outside in the next heavy rain and watch. A downspout emptying at the wall, a gutter overflowing at one corner, or a bed sloping toward the house explains more basement mold than foundations do — and it is free to find out.
Do not point a fan at it. Moving air across mold is how a problem in one room becomes a problem in four.
Do not paint over it. It hides for one season and takes away the option of a clean repair.
Run a dehumidifier. Lowering the humidity is the one thing available to you right now that stops it getting worse.
Bag and remove the soft things it has reached — carpet, pad, cardboard, upholstered furniture.
Do not pull a large area apart yourself. Disturbing it without containment is the reliable way to turn a contained problem into a whole-house one.
