What to Look for During a Duradek Inspection

As the days grow longer and the weather warms, deck season is finally here. We can enjoy our exterior living space once again. But before we place our summer furniture, it is a good idea to give it a quick inspection. Here is a quick list of what to look for.

1. Surface Condition and Wear

Start by examining the overall surface of the Duradek membrane. High-traffic areas, near door thresholds, or under furniture are especially prone to abrasion. While minor cosmetic wear is normal over time, excessive wear can compromise the membrane’s waterproofing ability and may indicate the need for repair or resurfacing.

2. Cracks, Punctures, and Tears

Carefully inspect the membrane for cracks, punctures, or cuts. These can be caused by dropped objects, sharp furniture legs, snow shovels, or improper use. Even small punctures are significant, as they allow water to penetrate beneath the surface, potentially leading to rot or structural damage. Pay close attention to corners and edges, where stress is often greatest.

3. Seams and Welds

Duradek installations rely on heat-welded seams to create a watertight surface. During an inspection, check all seams for signs of separation, lifting, or bubbling. Failed seams are one of the most common sources of leaks. Gently press along seam lines to ensure they are firmly bonded and free from gaps.

4. Flashings and Transitions

Inspect all flashings where the Duradek meets walls, doors, railings, posts, and stairs. These transition points are critical to keeping water out of the structure below. Look for loose metal flashings, cracked sealant, or areas where the membrane has pulled away. Improperly sealed penetrations around posts or fasteners can quickly lead to hidden water damage.

5. Drainage and Ponding Water

Proper drainage is vital for any vinyl deck system. Check for signs of ponding water, staining, or debris buildup that could obstruct drainage. Ensure the deck has adequate slope and that scuppers, drains, or edges allow water to flow freely away from the surface.

6. Substrate and Structural Indicators

While the substrate is not always visible, watch for warning signs such as soft spots, sagging areas, or unusual movement underfoot. These may indicate moisture intrusion or deterioration of the deck structure beneath the Duradek. Any spongy or uneven areas should be investigated further.

7. Maintenance and Cleanliness

Finally, assess the overall cleanliness and maintenance of the deck. Confirm that the deck is being cleaned with Duradek approved methods.
