Late‑Winter Masonry Checklist: Fix Brick and Stone Before Spring Thaw

By February, most homeowners in the Durham Region are ready for spring. But before the snow melts and the spring rains arrive, your brick and stonework have one more major test to face: the freeze‑thaw cycle. Late winter is the ideal time to inspect your masonry and take care of repairs so your home or commercial building in Whitby, Oshawa, Bowmanville, Ajax, Courtice, Port Perry, Pickering and the GTA is protected before the thaw.

Why Late Winter Is Critical For Brick And Stone

Ontario’s winter puts enormous stress on masonry. Moisture seeps into small cracks, freezes, expands, and slowly forces brick, stone and mortar apart. By late winter, much of that hidden damage starts to show.

Catching issues now means you can:

• Prevent water from entering walls and foundations during spring rain

• Reduce the risk of loose brick or stone becoming a safety hazard

• Avoid more expensive structural repairs down the road

• Plan ahead for any larger masonry or foundation repair projects

A late‑winter inspection is especially important for older homes in downtown Whitby or Oshawa, as well as commercial buildings that have seen years of weather exposure.

How Do I Know If My Brick Needs Repair?

One of the most common questions homeowners ask is, “How do I know if my brick needs repair?” The answer lies in a careful visual check around your property.

Walk around your home or building and watch for:

• Cracked or crumbling mortar joints

• Bricks that look pushed out, loose or bulging

• Flaking, peeling or “powdery” brick surfaces (spalling)

• Gaps opening up around windows, doors or sills

• Cracks in steps, walkways, retaining walls or chimneys

Inside, pay attention to:

• New cracks in drywall or ceilings

• Doors or windows that suddenly start sticking

• Damp spots or musty odours near basement walls

These can all point to masonry issues or early foundation movement that should be assessed by a professional mason or foundation repair contractor.

Your Late‑Winter Masonry Checklist

Use this simple checklist to identify problems before the spring thaw in the Durham Region:

Exterior:

• Inspect brick and stone walls for cracks, gaps and spalling

• Check chimneys for loose bricks, missing mortar and leaning

• Examine steps, porches and walkways for heaving or sinking

• Look at stone veneer or custom stone features for separation from the wall

• Review retaining walls for bowing, cracking or leaning

Foundation:

• Walk the perimeter and look for vertical or stair‑step cracks

• Note any areas where water tends to pool against the foundation

• Check basement windows and sills for gaps or deteriorated mortar

Fireplaces And Chimneys:

• Inspect the masonry around the firebox for cracks

• Look at the chimney crown and cap (if visible) for damage

• Watch for white, chalky streaks on brick (efflorescence), a sign of moisture

If anything looks unsafe, loose or noticeably worse than last year, it’s time to call in a masonry and foundation repair specialist.
