Leaking decks are most common in properties built before 2004, where the detailing was built to the old building code and lacks adequate fall to shed water. These decks typically have a butynol, torch-on, or fibreglass membrane that has aged past its intended lifespan. Many also have direct-fixed screed and tiles that trap water against the membrane and accelerate failure.

Common signs your deck needs attention:

• Water staining on the ceiling or walls in the room below the deck

• Ponding water that sits on the deck after rain instead of draining away

• Lifting, bubbling or cracked membrane, or seams pulling apart

• Lifting or drummy tiles, or a spongy, soft feeling underfoot

• A deck that has become unsightly, tired, or a genuine safety hazard

If you are seeing any of these, the damage is usually tracking into the structure below, so acting early keeps the scope and cost down.

Every job starts with a comprehensive investigation. We identify why the membrane has failed, whether from poor original installation, age, or insufficient maintenance, and talk through your repair or rebuild options alongside the budget for each. Deck reconstruction usually involves several trades working in sequence: scaffold and shrinkwrap, builders, plasterers, waterproofers, tilers, joinery specialists and painters. Our team is experienced in replacing failed and leaking membranes and manages the entire process for you.

Where the weather demands it, we prefer to shrinkwrap and fully enclose the work area. It comes at a higher price point, but it allows for a seamless, properly cured repair despite the inclement weather Auckland is known for, rather than a job rushed between rain.
