Step 01
Acclimate the boards
Store boards on site, off the ground, flat and stickered so air can flow around them. Let them adjust to local humidity before installing.
New to Hardwoods · Installation Guide
Install your deck the right way, from the first board.
These are the core practices installers follow with dense hardwoods, thermally modified wood and composite. Plan with them before you order so you buy the right profile and fasteners.
Step 02
Build a sound, ventilated frame
- Follow local code for joist size and spacing; dense hardwoods and composite usually call for closer spacing.
- Leave open space under the deck so air can circulate. Poor ventilation is the main cause of cupping.
- Keep the frame level and flat before laying boards.
Step 03
Choose your fastening method
- Pre-grooved boards: use hidden clip systems for a clean, screw-free surface.
- S4S E4E boards: face screw with stainless steel screws. Pre-drill and countersink every hole in Ipe and Cumaru.
- Composite: use the clip system designed for grooved composite boards.
Step 04
Gap the boards
Leave consistent side gaps for drainage and seasonal movement, and end gaps where boards meet. Clip systems usually set the gap automatically.
Step 05
Seal every cut end
Apply end grain sealer to all cut ends of hardwood and thermally modified boards right after cutting. This reduces end checking and splits.
Step 06
Siding, cladding and ceilings
V-Joint and cladding boards go over a ventilated rain screen with furring strips. Keep a gap behind the boards for airflow and drainage.
This guide covers general best practices only. Always follow local building codes and the fastener or clip manufacturer's instructions, and consult a licensed contractor for structural work.
