Balcony Repair with Waterproof Vinyl Decking in Clark, NJ

We completed a full repair of a leaking balcony in Clark, NJ, tearing out the old surface and replacing it completely. The homeowner wanted more than a quick fix. They wanted a durable waterproof surface that could stand up to moisture and outdoor exposure.

We started by removing the old covering and inspecting the wood structure. From there, we prepared the substrate, installed new plywood, and sealed the joints. The last step was a Duradek membrane, which serves as the new waterproof vinyl decking system.

This balcony repair stopped the leak and protected the underlying wood structure from further water intrusion. It also gave the homeowner a clean new walking surface built for everyday outdoor use.

Balcony Repair and Waterproofing Process

The main issue with the balcony was water leakage. The existing surface and areas patched in earlier repairs had stopped providing reliable waterproof protection, so another localized repair wouldn’t have fixed the underlying problem.

So we removed the old covering completely and prepared the balcony for a new waterproof vinyl decking system.

For the finished surface, we installed a Duradek membrane. This waterproof vinyl membrane does two jobs at once: it protects the structure from water intrusion and doubles as the finished walking surface.

Getting the substrate right is especially important before the membrane goes down. Even a high quality waterproofing for a balcony decking system won’t perform as intended if the surface underneath is uneven, unstable, or poorly prepared.

We also offer professional balcony waterproofing and repair services for similar projects, including substrate restoration and new vinyl membrane installation.

Steps of the Project

1

Removal of the old balcony covering

We started by stripping off the entire existing surface. This exposed the underlying construction so we could inspect the balcony's actual condition instead of installing a new membrane over a compromised surface.

2

Cleaning and inspection of the wood structure

After demolition, we cleared away old material and construction debris. Then we inspected the exposed wood structure before moving forward with the rebuild.

3

Preparation of the substrate

Next, we prepared the existing structure to create a solid, stable base for the new decking system. We corrected any problem areas so the new plywood would sit on a properly prepared surface.

4

Installation of new plywood

We installed new plywood sheets across the entire balcony and fastened them securely to the structure. Each sheet was carefully fitted around the exterior walls, door openings, railing areas, and balcony perimeter.

Checking the surface and slope

Before moving on to the waterproofing, we checked the surface with a level. Slope matters on an exterior balcony. Rainwater needs to drain away from the house, not collect on the finished surface.

6

Joint preparation and sealing

The seams between the plywood sheets got special attention. All joints and other vulnerable areas were prepared and sealed before the vinyl membrane went down. That gave the finished system a smoother, more stable substrate.

Preparation of edges and transitions

We took extra care around the exterior walls, doors, and balcony perimeter. These transitions are among the most critical areas during waterproof deck repair because water intrusion often starts at edges, seams, and wall connections.

Installation of the Duradek membrane

Once the substrate was fully prepared, we installed the Duradek membrane across the entire balcony. The waterproof vinyl formed a continuous protective layer over the plywood substrate.

Finishing the balcony surface

A gray and brown vinyl finish with a wood grain appearance was selected for the project. It pairs well with the dark railing and light exterior walls. And because it works as a finished walking surface on its own, there's no need for an additional deck layer over the membrane.

Final inspection and cleanup

After installation, we inspected the finished surface, perimeter, and transition areas. Then we hauled all removed materials, plywood scraps, and construction debris off the property.

Balcony Repair Results

This balcony repair in Clark, NJ replaced the old leaking surface with a new waterproof balcony decking system.

The Duradek membrane now shields the wood substrate from direct rain and moisture. It forms a continuous waterproof layer and also acts as the balcony’s finished walking surface.

We didn’t just patch individual damaged areas. By replacing the old covering and properly preparing the underlying structure, we fixed the source of the water intrusion.

The finished balcony now has a clean wood grain look, and maintenance is simple. It’s also built for long term outdoor exposure to moisture and changing weather.

Project Cost and Timeline

The complete balcony repair covered removal of the old surface, wood structure prep, new plywood, treatment of joints and transition areas, the Duradek membrane, and final cleanup.
