Thinking of Adding a Garage, Shed, or Sunroom? Read This First

Introduction

Adding a garage, shed, or sunroom can add space and value to your home, but what’s under that new structure matters just as much as what goes on top. Many homeowners jump straight into design and construction, only to deal with settling, water issues, or permits that stall the entire project. It doesn’t have to be that way.

If you’re planning to build something new on your property in St. Thomas or Elgin County, here’s what you need to know about excavation and site prep before the shovel hits the ground.

1. Proper Excavation Sets the Stage for Stability

No matter the size of the structure, the soil beneath needs to be stable and level. Excavation clears the area, removes debris or soft spots, and prepares a solid, compacted base that won’t shift over time. Whether it’s a concrete slab or a full foundation, it all depends on a clean, solid start.

2. Drainage Planning Should Happen First

One of the biggest mistakes we see is poor drainage planning. If water isn't properly redirected during site prep, it can pool around your new structure or flow toward your existing foundation. Excavation helps shape the land, ensuring runoff moves away safely, protecting both new and old parts of your property.

3. Access and Equipment Matter More Than You Think

Tight backyard? Fence in the way? Adding a structure often means bringing in machinery to excavate and grade the site. Planning for access early prevents damage to landscaping and saves time. At PMD, we specialize in small-lot access and precision digs that fit your space.

4. Permits and Inspection Delays Can Be Avoided with Prep

Excavation doesn’t just help with physical prep, it helps keep your build legal and on schedule. A properly excavated site is easier for concrete crews, inspectors, and surveyors to assess. It also reduces surprises like buried debris, uneven terrain, or unstable soil during construction.

Final Thought

Adding to your home is exciting, but don’t overlook what’s underfoot. A few days of excavation and prep can save you weeks of frustration and years of repair.
