When balconies are built without proper sealing methods or durable waterproof membranes, they begin to fail, often within months. We’ve seen it happen across Woodland Hills. Contractors cut corners using thin coatings, unsealed seams, or ignoring layering techniques entirely.
Water seeps through tile joints, hairline cracks, or the edge flashings. Over time, that moisture doesn’t just stay outside. It invades the underlying structure, rotting beams, staining ceilings, and even damaging interior drywall. You may not see it until it’s too late.
McAllister Home Builders Inc. addresses these risks head-on during waterproof balcony installation in Woodland Hills, CA. Every layer we apply, from primer to membrane to finish coat, serves a purpose. We ensure the correct slope, flashing placement, and material compatibility.
Key installation practices we prioritize:
Each balcony we complete is not just dry; it’s built to stay dry through Woodland Hills’ weather conditions. Our approach removes future surprises and protects both structure and space.
A flat or poorly graded balcony quickly becomes a pond after every rainfall. The issue isn’t just cosmetic; standing water wears down membranes, causes swelling, and creates the perfect place for mildew to form. It gets worse when clogged drains or scuppers prevent water from escaping altogether.
These drainage issues are far too common in older homes and poorly constructed outdoor decks. Without early correction, pooling water can break down the entire balcony system.
McAllister Home Builders Inc. prevents this from happening. Our team builds and installs a waterproof balcony in Woodland Hills, CA, with long-term protection in mind. Our work ensures proper slope for runoff, unblocked pathways for water to exit, and built-in barriers that prevent intrusion at seams and thresholds.
What we include for lasting drainage:
These aren’t just extra touches; they’re essential to making your balcony last. If you’re tired of dealing with water stains, soft spots, or musty smells, it’s time to invest in a long-term fix. Call us at +1 (833) 319-1917 to talk about building your new waterproof balcony.
We eliminate the problem before it starts by designing your balcony with slope and runoff in mind, no pooling, no weak spots, just dry surfaces.
Our crew installs flashing where leaks commonly form. This extra protection at door thresholds, wall joints, and railing points keeps water out for good.
We water-test every waterproofed area before finalizing finishes. This ensures your balcony works under real conditions, not just ideal ones.
When done properly, it can last over 15 years without major maintenance. Materials and drainage planning both matter.
Yes. Water will sit and break down the membrane without proper slope, causing leaks and swelling underneath.
Only in some cases. Most balconies require removing old finishes to apply waterproofing correctly and ensure full adhesion.
