Gulf South home with exterior mold and mildew treated and sealed

Exterior Mold & Mildew Treatment in the Gulf South | Paint + Protection.

Mold and mildew on your exterior mean moisture is already trapped behind it. Protect Your Home. Shield Your Family.

Mildew streaks on your siding, brick, or stucco are not just a cosmetic problem. Mildew is the first visible warning of trapped moisture, and by the time you can see it outside, mold is often already growing behind the surface, in the wall, where you cannot see or smell it. That combination, visible mildew outside and hidden mold inside, is Climate Cancer working exactly the way it is built to: quietly, behind the surface, until the damage is advanced.

The problem

A one time cleaning does not stop mold and mildew from coming back.

Pressure washing or bleach can knock mildew off the surface for a season. Neither one touches the moisture behind the wall that is feeding it, so mildew comes back, usually within a year, sometimes faster in Gulf South humidity. Treating what you can see without addressing what is trapped behind the surface is a temporary fix for a problem that keeps generating itself.

When you book a diagnosis, I identify where mold and mildew are actually growing, what moisture source is feeding them, and how far the problem has spread behind the surface, not just what is visible. My crew treats and removes the existing growth, then addresses the source: failed caulk and seams, an old coating that traps moisture, or bare porous surfaces with no protection at all. Once the moisture source is corrected, the Climate Proof Ceramic Coating seals your exterior against new water while venting out what is already inside, so the conditions that grew the mold and mildew in the first place stop being there to feed anything new.

What you actually get

Home health, family health, and equity.

One system defends the three things that matter most about your home.

Your home stays healthy

Removing existing growth and correcting the moisture source means mold and mildew lose the water they need, instead of getting cleaned off and returning.

Your family is protected

Correcting the moisture that feeds mildew also addresses the mold growing where you cannot see it. Drier walls mean less mold and mildew for the air around your home to carry. This is not medical advice, and anyone with specific indoor air quality or health concerns should talk to a qualified professional.

Home equity protected by a transferable warranty

Your equity is protected

Visible mildew is a red flag for buyers and appraisers alike. Treating the growth and correcting its source, backed by a 25 year transferable warranty on the coating that follows, turns a visible problem into a documented, protected home.

How the diagnosis works

I don't give estimates. I give diagnoses.

Kevin Mmahat, Exterior Home Protection Consultant

When you book your free Home Protection Consultation, I come out myself. I do not give estimates. I give diagnoses. I look at every elevation for mildew streaks, efflorescence, and soft or discolored spots that point to moisture behind the surface, and I identify the source, whether it is failed caulk, an old coating trapping water, or bare porous material with nothing protecting it. I tell you what is actually happening, not just what you can see. Then my crew treats and removes the existing growth, corrects the moisture source, and applies the ceramic system where coating is part of the fix. You get an exact written number before a single thing begins.

Mold & Mildew Questions

Your questions, answered.

The questions homeowners ask before they book.

Cleaning the existing growth is part of the job, but it is not the whole job. If we do not correct the moisture source feeding it, mildew comes back. Even the home improvement guides say the same thing about the bleach-and-hose approach: chlorine bleach evaporates before it reaches the fungi's roots, leading to regrowth, and no cleaner of any kind fixes the damp conditions the growth feeds on. We treat what is there and fix what is causing it.

Then that is what gets fixed. A common source we find is cracked or failed caulk letting rain behind the surface, and in those cases we reseal the failed joints and entry points as part of the treatment.

Mildew on the surface is often the first visible sign that moisture is already trapped behind the wall. During the diagnosis I check for soft spots, discoloration, and moisture readings that point to what is happening behind the surface, not just what is visible.

No. This is exterior surface treatment and moisture correction, not medical advice. If you have specific health concerns related to mold exposure, talk to a qualified medical professional.

Once the moisture source is corrected, the coating seals your exterior against new water while venting out what is already inside, which removes the conditions mold and mildew need to keep coming back.

Cleaning and treatment address what is there now. Where the fix includes the Climate Proof Ceramic Coating, that coating is backed by the 25 year transferable warranty.
