Understanding Sill Damage: Indicators You Need Sill Repair in Montreal


Window sills, especially those made of brick or stone, are prone to damage due to their exposure to the elements. In Montreal's fluctuating weather conditions, these sills can deteriorate over time and may require repair. But how can you tell when your sills need fixing? In this guide by Maçonnerie Montréal, we'll take a look at the key signs indicating that your sills require professional attention.

Visible Cracks

The first and most obvious sign that your sills need repair is the presence of visible cracks. These can vary in size and severity but should never be ignored. Even minor cracks can become bigger over time, leading to serious structural issues that may require extensive repairs.


Efflorescence is a white, powdery substance that forms on the surface of brick or stone sills when water seeps into the material and then evaporates, leaving behind salt deposits. If you notice efflorescence on your sills, it's a clear sign that water is penetrating the material, which can lead to more severe damage over time.

Discolouration and Staining

Another sign that your sills may need repair is discolouration or staining. This can be caused by a variety of factors, including water damage, exposure to harsh weather conditions, or the natural ageing process of the material. If your sills are significantly discoloured or stained, it may be time to call in the professionals.

Sagging or Bulging

Sagging or bulging sills are a clear indicator of damage. This can occur when the material begins to deteriorate, causing the sill to lose its structural integrity. If you notice that your sills are sagging or bulging, it's important to get them repaired as soon as possible to prevent further damage.

Crumbled Pieces

If pieces of your sill have crumbled away, it's an obvious sign that you need repairs. Crumbling can occur as a result of weathering, water damage, or simply the age of the material. If left unchecked, this can lead to the complete failure of the sill and potentially cause damage to the surrounding structure.
