Gulf South home with every seam and joint resealed

Exterior Caulking & Moisture Sealing in the Gulf South | Paint + Protection.

Failing caulk and open seams let wind driven rain behind your walls. Protect Your Home. Shield Your Family.

Gulf South storms do not just fall straight down. Wind drives rain sideways into every gap on your exterior: around windows and doors, along siding laps, at trim joints, wherever two materials meet. Caulk and sealant are what keep that water out at those seams. Caulk dries out, cracks, and shrinks under years of sun and heat, and once it fails, wind driven rain has a direct path behind your siding, trim, and walls, whether or not the paint on the surface still looks fine. That hidden path behind a failing seam is one of Climate Cancer's quietest ways in, because the surface can look untouched while water is already getting through.

The problem

Most repainting skips the seams.

Most exterior painting gets judged by how the surface looks. A fresh coat can go on right over old, cracked caulk without anyone touching the seams underneath. The paint looks new, but the same failed joints keep letting rain behind the wall. Repainting over failing caulk protects nothing at the one place water is actually getting in.

Before we coat anything, my crew inspects and reseals every seam, joint, and penetration on your exterior: window and door perimeters, siding laps, trim joints, and anywhere two materials meet. We remove old, failed caulk rather than caulking over it, and seal with materials built to move with your home through Gulf heat and humidity instead of cracking. That work happens before the Climate Proof Ceramic Coating goes on, so the coating protects a surface that is already sealed at every entry point, not one with the same gaps hidden underneath a new color.

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

Sealed seams keep wind driven rain from ever reaching the wood and wall assembly behind your exterior, which is where the moisture that feeds mold and rot actually starts. When water has been getting through failed seams for years, the diagnosis also checks whether wood behind the seam already needs replacing.

Your family breathes easier

Stopping water at the seams means less moisture working its way into your walls in the first place, so there is less feeding the mold and mildew that affect indoor air.

Home equity protected by a transferable warranty

Your equity is protected

Resealing every entry point before coating means the coating is not covering up the same leak points that caused problems before. Doing the seams right is part of doing the coating right, and the coating carries the 25 year transferable manufacturer's warranty.

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 check every window, door, siding lap, and trim joint on your exterior for cracked, shrunk, or missing caulk, because that is where wind driven rain gets in first. I tell you exactly which seams have already failed and where water has likely already been getting through. Then my crew removes the old caulk, reseals every point that needs it, and preps the surface before the ceramic system goes on. You get an exact written number before a single thing begins.

Caulking Questions

Your questions, answered.

The questions homeowners ask before they book.

Resealing seams and joints is part of the prep on every Climate Proof Ceramic Coating job, and it is also available as its own service if your caulk has failed but you are not ready to coat yet.

Look for cracking, gaps, powdering on the surface, or caulk that has shrunk or pulled away from the joint at windows, doors, and siding laps. Caulking professionals put the working life of exterior caulk at roughly five years, less under weather extremes and structural movement, and Gulf South heat and storms sit squarely in the "less" category. Failed caulk often does not show from a distance, which is why it gets missed during a standard repaint.

Old, failed caulk does not give new caulk anything solid to bond to, so caulking over it fails again fast. We remove what has failed and seal to the sound material underneath.

No. Sealing stops water at the entry points. The coating protects the wall surface itself. Gulf South homes need both, which is why sealing is part of every coating job.

We seal with materials made to flex with your home instead of drying out in a few summers. When the sealing is done as prep for a full coating job, the coating that goes over your exterior carries the 25 year transferable manufacturer's warranty.
