Expert Verdict — Reviewed by the SuperArbor Pro Desk

Match the block color exactly to your siding color name rather than eyeballing, since ProVia offers close shades like Gray, Myst Gray and Granite. Install the block before or during siding installation where possible so flashing and nailing integrate cleanly. For wet locations such as hose bibs, follow local code for sealing behind the block.

For electrical fixtures, have wiring installed or inspected by a licensed electrician and follow local building codes.
