The Homeowner's Pre-Installation Checklist for Tropical Hardwood Decks

Before They Break Ground: Your Checklist

Investing in a tropical hardwood deck is exciting, but preparation is key to a successful project. This checklist covers everything homeowners should verify, discuss, and prepare before the first board is cut.

Before Hiring

• [ ] Verify EHCI Certification: Ask the contractor for their Certificate ID and verify at ehcertification.com/Verify. Confirm active status and check which specific certifications they hold.
• [ ] Check References: Ask for 3–5 references from previous tropical hardwood (not composite or PT) clients. Contact them and ask about the installation quality, timeline accuracy, and communication.
• [ ] Review Portfolio: Ask to see photos of completed hardwood projects, including close-up details of fastener patterns, edge details, and finish quality.
• [ ] Confirm Insurance: Verify that the contractor carries general liability insurance and workers' compensation coverage. Ask for a certificate of insurance naming you as additionally insured.
• [ ] Get Multiple Quotes: Obtain at least three detailed proposals from different contractors. Compare not just total price but material specifications, fastener types, warranty terms, and scope of work.

Before Construction

• [ ] Permit Status: Confirm that the building permit has been applied for and approved. Ask to see the approved permit and understand what inspections are required.
• [ ] Material Specification: Verify the exact species (by name), grade (Select or Standard), profile (5/4x6, etc.), and source. Confirm FSC certification status if this is important to you.
• [ ] Fastener Specification: Confirm that stainless steel fasteners (Type 305 or 316) are specified. Ask which specific product will be used.
• [ ] Site Access: Ensure the contractor has clear access to the work area. Remove patio furniture, planters, grills, and other items. Discuss material staging location.
• [ ] Utility Locates: Call 811 to have underground utilities marked before any excavation for footings or posts.
• [ ] Neighbor Communication: Notify neighbors about the project timeline, especially if construction noise or access through shared areas is expected.

During Construction

• [ ] Acclimation Verification: Confirm that lumber has been acclimated on site for a minimum of 5–7 days before installation begins.
• [ ] Moisture Content Check: Ask the contractor to show you moisture meter readings before installation. Accept boards in the 12–16% MC range for most climates.
• [ ] Pre-Drilling: Visually confirm that every fastener hole is being pre-drilled. This is non-negotiable with tropical hardwood.
• [ ] End Sealing: Verify that all field-cut board ends are being sealed with end sealer immediately after cutting.
• [ ] Board Spacing: Check that consistent gaps (1/8" to 3/16") are maintained between boards.

At Completion

• [ ] Final Walkthrough: Walk the completed deck with the contractor. Check for proper spacing, flush fasteners, clean finish application, and no visible damage.
• [ ] Maintenance Instructions: Receive written maintenance instructions including cleaning procedure, finish product name, reapplication schedule, and dos/don'ts.
• [ ] Warranty Documentation: Receive written workmanship warranty from the contractor and material warranty documentation from the lumber supplier.
• [ ] Final Inspection: Confirm that the building department has conducted and approved the final inspection.
