“My husband and I noticed mold on a couple of different spots on a baseboard and outlet plugs that were below some windows. We remembered having a great experience from a few years back with Mike Wotruba at CCS about an issue we had going on in our basement, so we gave him a call right away.”

“We recently had our roof done and I wanted a second pair of eyes to ensure no mold was present due to having leaks for some time. Mike Wotruba showed up thankfully after roofing rescheduled twice and he was so accommodating. Super helpful with questions and went above and beyond for me. Highly recommend this company as they are very responsive and thorough.”

“I had, what I consider, to be a decent mold problem in my basement. I was unsure of who I should call, so I decided to read the reviews posted by other people that used CCS Property Services to see if they would be a good fit.”

Mold problems we handle every week

Basement and attic mold

Musty basements after leaks or high humidity, and attic sheathing mold from poor ventilation. We remove, treat and encapsulate where it makes sense.

Black mold

Dark mold on drywall, wood or around windows. Color doesn't tell you how harmful it is. Size and cause do. We'll assess it free.

Mold found during a home inspection

Buying or selling? We assess quickly, explain whether it's a real issue, and give you a written plan and price for the other party.

Mold after a leak or flood

Mold can start within 24–48 hours on wet materials. If it came from a sudden leak, insurance may cover it.

How we get rid of it, in 3 steps

1

Free mold assessment

A CCS tech inspects the area, finds the moisture source and shows you exactly what's there.

2

Clear plan and price

You get a written scope before any work starts. If it's an insurance claim, we work directly with your adjuster.

3

Remove, treat, restore

We contain the area, remove the mold, treat what's left, dry it out and rebuild anything we had to take out.

We work with your insurance

We photograph and measure the damage, write a detailed scope, and work directly with your adjuster. If the first offer doesn't cover the real cost of the repairs, we help you push back with documentation. You can generally choose your own contractor in Wisconsin.

Quick answers

Is the mold assessment really free?

Yes. We inspect, look for the moisture source and walk you through what we find. You only pay if you choose to move forward with remediation.

How much does mold remediation cost?

It depends on how much area is affected and what caused it. A small bathroom or window area costs far less than a full basement. You get a written price before any work starts.

Will my homeowners insurance cover mold?

Often it does when the mold comes from a sudden covered event, like a burst pipe or appliance leak. Mold from long-term humidity or slow leaks usually isn't covered. We'll tell you which it looks like.

Can I stay in my home while you work?

Usually, yes. We seal off the work area and run HEPA filtration so spores don't spread.

Will the mold come back?

Not if the moisture is fixed. Every job starts by finding the source, whether it's a leak, poor ventilation or humidity.
