What Customers Say After We Sealed Their Walls and Windows

Wall and window leaks are some of the hardest to track down. Read what South Florida property owners say about how A-1 found the source and sealed it for good.

Exterior wall waterproofing for wind-driven rain

Exterior wall waterproofing matters more here than almost anywhere else. During summer storms and hurricanes, rain does not just fall. It blows sideways against the building with enough force to push water through hairline stucco cracks, porous block and aging caulk.

Most homes and condos in South Florida are concrete block with a stucco finish. Stucco is tough, but it cracks as buildings settle and heat up and cool down. Paint alone does not bridge those cracks for long, and once water gets behind the stucco it can stain interior walls, rot window framing and feed mold.

We seal the wall as a system: crack repair, sealant at every joint and opening, and an elastomeric wall coating that stretches over hairline cracks and sheds water. The result protects the building and gives it a fresh finish.

What we seal

Signs water is getting through your walls

Wall leaks often show up far from where the water enters. Watch for these clues.

Stains after storms

Damp spots or stains on interior walls that appear after wind-driven rain, not every rain.

Leaks around windows

Water on sills, swollen trim or peeling paint below a window usually points to failed perimeter sealant.

Stucco cracks

Map cracking and cracks running from window corners let water behind the finish.

Blistering paint

Bubbles in exterior paint are a sign that moisture is trapped in the wall.

Musty rooms

Persistent odors or mold near exterior walls can mean hidden moisture inside the wall.

We check the roof, gutters and flashing too, because water that looks like a wall leak sometimes starts above.

Stucco waterproofing and wall sealing services

We combine these services based on what the wall needs.

Elastomeric wall coating

A thick, flexible coating that bridges hairline cracks, sheds water and still lets the wall breathe. Available in many colors.

Stucco crack repair

Cracks are opened, filled with flexible patching and textured to match before any coating is applied.

Window perimeter sealing

Old caulk is cut out and replaced with high-performance sealant around windows, doors and sliders.

Joint and penetration sealing

Control joints, expansion joints and every wall penetration are sealed so water has no easy path in.

How we waterproof exterior walls

Most single-family homes take a few days. Condo and commercial walls are scheduled by elevation.

Inspect

We map cracks, failed sealant and suspect openings, and water-test problem areas when needed.

Clean

Walls are pressure washed and loose paint and failed caulk are removed.

Repair and seal

Cracks are repaired and new sealant is installed at windows, doors, joints and penetrations.

Coat

Primer and elastomeric coating go on at the thickness needed to bridge cracks and shed water.

Final check

We walk the building with you and document the finished work with photos.

Exterior wall waterproofing FAQs

Is elastomeric paint the same as regular exterior paint?

No. Elastomeric coatings go on much thicker and stay flexible, so they can stretch over small cracks. Standard exterior paint is thinner and cracks along with the stucco.

Why do my windows leak only during storms?

Wind-driven rain pushes water into gaps that normal rain never reaches. Failed perimeter caulk, cracked stucco around the frame and worn weatherstripping are common causes.

Can you waterproof just one wall?

Yes. If only one elevation takes the weather, we can seal that wall and its windows. We will tell you if other walls show the same wear.

Do you work on condo and commercial buildings?

Yes. We handle wall sealing and coatings for condos, HOAs and commercial buildings, often alongside concrete and balcony repairs.

What warranty comes with wall waterproofing?

Our waterproofing work includes a written workmanship warranty of 5 to 15 years depending on the system and scope.
