Should You Install Eavestroughs on a Detached Garage in Gloucester?

Yes, installing eavestroughs on your detached garage in Gloucester is a smart investment that protects both the structure and your property. Even though a garage may seem like a low-priority building, water pouring off an uncontrolled roof edge causes the same foundation damage, soil erosion, and ice hazards that it creates on your main house.

Why Garage Eavestroughs Matter in Ottawa

Gloucester sits on some of Ottawa's most problematic Leda clay soil, which swells when saturated and shrinks when dry. Without eavestroughs directing roof runoff away from your garage foundation, concentrated water dumps along the perimeter saturate the clay and accelerate foundation cracking. Over a few Ottawa winters with 50-plus freeze-thaw cycles, that saturated soil heaves and shifts, pushing garage walls out of plumb and cracking concrete slabs. Repairing a shifted garage foundation costs $3,000 to $8,000 or more, far exceeding the cost of a simple eavestrough installation.

Water sheeting off an unprotected garage roof also creates dangerous ice patches on your driveway and walkways during Ottawa's long winter. If your garage opens onto a shared laneway or is near a sidewalk, that ice becomes a serious liability concern.

For a typical detached two-car garage in Gloucester with 40 to 60 linear feet of roof edge, a seamless aluminum eavestrough installation runs $400 to $900 including downspouts. Most contractors can complete a garage installation in a single morning. You will want a minimum of two downspouts, one at each end of the longest gutter run, with extensions directing water at least 1.8 metres away from the foundation as required by the Ontario Building Code.

The best time to install garage eavestroughs is during Ottawa's prime season from May through October, and many homeowners bundle the garage with a main house eavestrough replacement to get better per-foot pricing. If your garage has no fascia board, the contractor will need to install one first, which adds $12 to $25 per linear foot but provides the structural mounting surface the eavestroughs require.

One practical tip specific to Gloucester garages: because many detached garages are set back on the lot near mature trees, consider adding a basic leaf guard system at the time of installation. Gutter guards on a short garage run add only $100 to $250 but save you the hassle of climbing a ladder twice a year for cleaning.
