AZEK (PVC Trim)

Q: How do you fill the gap between a fence and a house?

The standard professional solution is AZEK cellular PVC L-trim, cut to fit the gap between the fence and the house wall. AZEK does not rot, warp, or require painting, and blends with white or painted vinyl fence components. It is secured to the fence post or panel for a clean, maintenance-free closure.

Q: What do fencing contractors use to close the gap under a fence?

The approach depends on the gap size and cause. For terrain-related gaps from stair-stepped vinyl fencing on a slope, AZEK trim fills the gap between the panel bottom and the ground. For larger grade drops, grading or a concrete base may be required. Thrive addresses gap management during the design phase so solutions are built into the installation plan.

Definition

AZEK is a brand of cellular PVC building trim used in fencing to close gaps that standard panel configurations cannot eliminate. Common applications: (1) gap between a fence and a house wall where the fence terminates against siding; (2) ground-level gap under stair-stepped vinyl panels on sloped lots; (3) gap at irregular terrain where panels cannot be adjusted lower. AZEK does not rot, warp, or require painting, and blends with white or painted vinyl fence components. It is cut to fit on site and secured to the fence post or panel.
