Balcony Waterproofing & Coating
in Southern California
Protect your elevated structures from water intrusion
What Is Waterproofing?
Water intrusion is the number one cause of balcony failure. Without proper waterproofing, moisture penetrates the decking and destroys the structural framing beneath. We install premium multi-layer waterproofing systems, elastomeric coatings, and proper flashing to ensure your balconies, walkways, and decks remain completely watertight and structurally sound for decades.
What's Included
Our Process
Surface Preparation
We remove old coatings and prepare the substrate to ensure maximum adhesion.
Flashing & Sloping
We install proper metal flashing and apply sloping compounds so water drains away from the building.
Waterproof Membrane
A flexible, heavy-duty waterproof membrane is applied to seal the entire deck surface.
Traffic Coating
We apply a durable, UV-resistant topcoat that provides a slip-resistant and attractive finish.
Frequently Asked Questions
How long does balcony waterproofing last?
With proper installation and maintenance, a high-quality urethane waterproofing system can last 10-15 years before needing a recoat.
Can you waterproof over tile?
Generally, no. Tile must be removed to inspect the subfloor and apply the waterproofing membrane directly to the structural deck for a true seal.
