THE HIDDEN RISKS OF "HARWICH HUMIDITY"

In Harwich, a deck is more than a platform; it is a structure constantly under siege. Most local failures aren’t caused by the visible boards, but by what is happening underneath.

The Pleasant Bay Effect: Homes near the water face relentless salt spray and high-velocity winds. Standard galvanized fasteners will corrode within years, leading to "board pop" and structural instability.
The Moisture Trap: Many Harwich decks are built too low to the ground with poor ventilation. This creates a "terrace oven" effect where trapped moisture rots the joists from the bottom up, long before the surface looks old.
The Historic & Conservation Hurdle: Navigating the Harwich Conservation Commission or Historic District requirements can stall a project for months. If your contractor doesn't understand the "Buffer Zone" rules, you risk heavy fines and a halted build.

THE LIONS DECK PROTOCOL

Our Disciplined Approach to Building a Better Deck

Site-Specific Foundation Analysis

Harwich soil varies from sandy shoreline to dense woods. We evaluate your ground conditions to determine the exact depth and diameter required for footings to ensure your deck never heaves or settles.

The Structural "Code-Plus" Frame

We utilize pressure-treated lumber rated for "Ground Contact," even if it isn't touching the earth. Our framing involves joist tape to prevent water from sitting on top of the wood, a critical step that doubles the life of your frame.

Coastal Hardware Standard

Within 5 miles of the Sound or Bay, we utilize 316-grade stainless steel hardware. It is a non-negotiable standard for us because Harwich salt air eats standard zinc-coated bolts for breakfast.

Proper Flashing & House Protection

The most dangerous part of a deck is where it meets your house. We use a multi-layered flashing system to ensure water is directed away from your home’s rim joist, preventing internal rot and structural damage to your kitchen or living room walls.

Precision Joinery

Our in-house carpenters are craftsmen, not laborers. We focus on tight miters, consistent spacing for drainage, and hidden fastening systems that provide a barefoot-friendly surface.

BEYOND THE SURFACE: THE "MOISTURE SANDWICH" DANGER

We often see Harwich homeowners who want to “just put new composite over the old wood.” We strictly advise against this unless the frame is pristine. Placing modern, non-breathable composite over an aging, damp wood frame creates a “moisture sandwich” that accelerates rot. At Lions, we provide a transparent assessment of your sub-structure. If the bones aren’t good, we won’t put a new skin on them. It is about honesty and your family’s safety.
