Our Building Waterproofing Services
We provide complete restoration solutions tailored to your building. Each project addresses your specific damage type.
Brick Repair & Replacement
We replace damaged or spalling bricks with matching materials to maintain structural integrity and appearance. Toronto’s freeze-thaw cycles cause brick faces to flake and crumble. We source matching bricks from local suppliers or custom firing for heritage properties.
Tuckpointing (Mortar Joint Repair)
We remove deteriorated mortar to 2x joint width and replace it with durable, compatible mortar to prevent water intrusion. Toronto’s 40+ freeze-thaw cycles erode mortar, creating entry points for moisture. We match mortar color, hardness, and profile to original.
Stone Restoration
We repair and restore natural stone surfaces including limestone, sandstone, and granite. Spalling, cracking, and surface erosion are common in older Toronto buildings. Our team uses specialized stone repair mortars and consolidation treatments.
Masonry Crack Repair
We repair structural and surface cracks using epoxy injection, routing and sealing, or stitching methods. Left unaddressed, cracks widen during freeze-thaw cycles and allow water infiltration. For load-bearing cracks, see our Structural Repair Toronto page.
Cleaning & Sealing
We clean masonry surfaces using low-pressure washing (below 500 PSI) or chemical cleaners, then apply breathable sealants. Proper cleaning removes efflorescence and pollutants. Sealing extends masonry life by 5-10 years without trapping moisture.

What Causes Masonry Damage in Toronto
Masonry deterioration is accelerated by Toronto’s unique climate. Understanding the cause helps us design permanent repairs.
Freeze-thaw cycles – Water enters mortar joints and brick pores, freezes at 0°C, expands by 9%, and fractures masonry. Toronto experiences 40+ cycles annually, widening cracks by 0.5-1.5mm per year.
Water penetration – Moisture travels through deteriorated mortar joints, reaching interior walls and causing mold, rot, and efflorescence.
Salt exposure – De-icing salts react with brick and mortar, accelerating spalling and surface deterioration, especially near roads and sidewalks.
Aging materials and poor maintenance – Mortar typically lasts 50-75 years. Buildings from 1950-1970 are now entering major restoration window.

Signs You Need Masonry Restoration
Ignoring these signs can lead to water damage, structural issues, and heritage compliance problems.
Cracked or missing mortar joints – Mortar should be firm and flush. Deep gaps indicate erosion.
Spalling or flaking bricks – Brick faces crumbling or popping off. Indicates freeze-thaw damage.
Water leakage through walls – Damp interior walls after rain. Mortar joints likely failed.
Efflorescence (white staining) – Mineral deposits left by evaporating water. Indicates chronic moisture.
Loose or shifting bricks – Bricks that move when pressed. Immediate safety concern.
Bulging or leaning walls – Critical sign of structural failure. Emergency repair required.
Vegetation growing in joints – Weeds or moss indicate deep mortar deterioration.
👉 Delaying restoration by one year can double repair costs and create safety liabilities.
Our Masonry Restoration Process
01.
Inspection & Assessment
We evaluate mortar condition, brick spalling, cracks, and efflorescence using sounding hammers and moisture meters.
02.
Removal of Damaged Mortar/Brick
Deteriorated mortar is ground out to 2x joint width (15-20mm deep). Spalled bricks are removed individually.
03.
Material Matching
Critical for heritage buildings. We match brick color, size, texture, and firing method. Mortar match includes color, sand gradation, and lime content.
04.
Repair & Replacement
New mortar is installed in layers (2-3 lifts for deep joints). Bricks are laid with proper bond patterns and tooled joints.
05.
Sealing & Protection
Breathable silane/siloxane sealer applied. Allows vapor to escape while repelling liquid water.
06.
Final Quality Inspection
We verify mortar hardness, joint profile, color match, and water resistance. You receive a completion report.
