The Hidden Cost of Uncertified Installation: A Homeowner's Cautionary Tale

It Started With a Great Deal

Last spring, a homeowner in Tampa reached out to us after discovering significant problems with their 18-month-old Ipe deck. The boards were cupping badly, several had split at the fastener points, and there were visible rust stains running down the side of their home from the railing hardware.

The deck had cost $28,000 installed. It was going to cost another $14,000 to tear out and rebuild correctly.

What Went Wrong

The original installer was experienced with composite decking and standard pressure-treated lumber. He'd never worked with tropical hardwoods before but figured "wood is wood."

Here's what the assessment revealed:

No pre-drilling. The installer drove screws directly into the Ipe without pre-drilling. At 3,680 lbf Janka hardness, Ipe doesn't tolerate that. The result: splits radiating from nearly every screw hole, creating entry points for moisture.

Wrong fasteners. Standard zinc-plated deck screws were used instead of stainless steel. The tannins in Ipe are highly corrosive to non-stainless metals, causing the dark rust staining on the siding below.

No acclimation. The boards were installed within 48 hours of delivery. The moisture content was still well above equilibrium for Tampa's climate. As the boards dried, they shrank—but they were fastened too tightly to move, so they cupped and checked.

Inadequate gapping. The boards were butted nearly tight, composite-style. When they did absorb moisture seasonally, they had nowhere to expand.

The Rebuild

The homeowner hired an EHCI-certified installer for the rebuild. The new installation included proper stainless steel fasteners, pre-drilled pilot holes, correct spacing for seasonal movement, and end-grain sealer on every cut. Same wood species, completely different result.

The Lesson

Tropical hardwoods aren't forgiving of general carpentry shortcuts. The skills that work perfectly well on softwood and composite don't transfer directly. That $2,000 saved on the initial bid turned into $14,000 in additional costs—plus the stress, the time, and the damage to the home.
