Expert Verdict — Reviewed by the SuperArbor Pro Desk
Install the starter straight off the sheathing and over the weather-resistive barrier so the first course locks fully and sheds water correctly. Snap a level chalk line across the whole elevation and keep every starter on that line. Choose the new construction profile for open walls and the remodeling profile when siding over existing cladding.
Use appropriate ladders, lifts and fall protection when working at elevation, and follow the manufacturer's fastening instructions.
Order the Mastic New Construction Lineal Starter in White to start your next siding job on a level, secure base.
