Deck Foundation Repair in Onondaga, MI

Helical pier foundation repair stabilized a sinking deck in Onondaga, Michigan, preserving a family home.

Gary and Julie’s home in Onondaga, Michigan, is a gorgeous home they’ve cherished and shared with family for years. Their spacious deck overlooks a scenic man-made pond, making it a key feature in how they enjoy their property. So they knew it was time to act when they noticed signs of significant settlement, nearly 7 inches of sinking!

Their first step was contacting a structural engineer to explore replacement options. But before committing to such a major (and costly) project, they contacted Ayers Basement Systems for a free estimate.

The Ayers Approach: Repair, Not Replace

Instead of removing and rebuilding the deck from scratch, Ayers proposed a more eco-friendly and less invasive solution: reinforce and relevel the existing structure using a combination of helical and deck piers. Our System Design Specialist developed a customized plan tailored to the unique conditions of Gary and Julie’s property. To ensure the piers could be properly installed, the team carefully relocated large landscaping stones that surrounded the deck. With the area cleared, they proceeded with manual installation, staying focused on delivering lasting stability without disrupting the surrounding yard.

What Are Helical Piers?

Helical piers are long steel shafts with helical plates (like large threads) twisted deep into the ground to reach stable, load-bearing soil. Once installed, these piers permanently stabilize a sinking foundation, or, in this case, a deck. They’re ideal for structures experiencing settlement or those built on unstable or wet soil, and they’re commonly used to:

Lift and stabilize sinking home foundations 
Reinforce porches, decks, and patios 
Support new construction or additions 

The installation process is quick, minimally disruptive, and offers immediate load-bearing support.

Products Used on Gary & Julie’s Project

• Helical Piers: To stabilize and relevel the sinking deck
