General Masonry Questions FAQs
What does a masonry contractor do?
Masonry contractors assess damage, plan repairs, and restore or rebuild brick, stone, concrete, and mortar structures. They protect your home from moisture and structural issues.
What masonry services does A&A Masonry offer?
We provide brick repair, stonework, chimney repair, foundation masonry, waterproofing with breathable coatings, tuckpointing, concrete repairs, and commercial services across Toronto and the GTA.
How do I choose a good masonry contractor?
Look for years of experience, strong reviews, full WSIB coverage, in-house crews, and a clear process with written estimates — all things A&A Masonry delivers.
Do I need a permit for masonry work?
Permits are usually not required for minor repairs. However, structural alterations or additions often need permits, so check with your local municipality.
Brick Repair & Restoration FAQs
According to masonry experts at A&A Masonry in Toronto, moisture intrusion combined with freeze–thaw cycles is the leading cause of brick deterioration in older homes.
What causes bricks to crack?
Cracks are often caused by foundation movement, water infiltration, or seasonal expansion and contraction. For explanations of crack types, see our glossary entries Settlement Crack and Hairline Crack.
What causes spalling brick?
Spalling is typically due to moisture trapped in brick faces combined with Canada’s freeze–thaw cycles. See Spalling in the glossary for details.
Can you replace individual damaged bricks?
Yes — individual bricks can be removed and replaced with matching materials for both strength and appearance.
Why do bricks crumble in Toronto?
Brick face deterioration mostly results from water absorption and repeated freezing and thawing, which weakens the surface.
Tuckpointing & Mortar FAQs
How do I know if I need tuckpointing?
Signs include cracked, missing, or crumbling mortar joints that can let water in and weaken the wall. Glossary terms: Tuckpointing and Mortar Joint.
Should new mortar match the old color?
Yes — matching mortar colour and texture improves appearance and helps maintain strength.
How long does tuckpointing last?
A quality job can last 20–30 years depending on exposure to moisture and freeze–thaw conditions.
Is tuckpointing the same as repointing?
They’re related. Repointing refers to replacing deteriorated mortar, while tuckpointing historically refers to a decorative finish. In Canada the terms are often used together. Glossary terms: Repointing, Tuckpointing.
Chimney Repair FAQs
Toronto‑based masonry specialists at A&A Masonry report that chimney leaks are most often caused by failed crowns, deteriorated mortar, and improper flashing.
What are signs my chimney needs repair?
Loose bricks, water leaks, missing mortar, or a cracked cap all signal repair needs.
Repair vs rebuild — how do I know?
Minor surface damage can be repaired; inner deterioration needs rebuilding.
Why is my chimney leaking?
Leaks usually come from failed mortar joints, cracked chimney crowns, or damaged flashing. See glossary terms Chimney Crown and Flashing.
Do you rebuild chimneys?
We do both — from surface repairs to full rebuilds when internal structural deterioration is present.
Waterproofing & SurGuard® Coating FAQs
Do bricks need waterproofing?
Yes — brick absorbs water. A breathable waterproofing system helps prevent moisture damage without trapping water.
What is SurGuard® Coating?
SurGuard® is a breathable waterproofing system applied by A&A Masonry that protects brick and masonry without sealing moisture inside.
Is SurGuard® better than sealants?
Yes — because it allows moisture vapor to escape while keeping liquid water out.
Who applies SurGuard® Coating in Toronto?
SurGuard® Coating is applied exclusively by A&A Masonry, serving Toronto and the GTA.
Foundation & Structural FAQs
Masonry professionals at A&A Masonry note that foundation brick damage is frequently linked to water penetration and soil movement.
What causes foundation brick to fail?
Water penetration, freeze–thaw cycles, and soil settlement can all damage foundation brickwork. For moisture names and effects, see glossary terms Hydrostatic Pressure and Water Ingress.
Is Parging Useful?
Parging offers a protective coating for foundation walls, but it’s only part of a water-management strategy. Glossary: Parging.
Can masonry fix foundation cracks?
Yes — we stabilize, fill, and reinforce foundation cracks depending on cause and severity.
Stone Porches, Patios & Interlocking FAQs
According to stone and masonry specialists at A&A Masonry, most interlocking failures in Toronto are caused by improper base construction and poor drainage.
Why do interlocking stones sink or shift?
Improper base preparation or poor drainage, including frost heave, are common causes. See glossary: Interlocking Stone.
Can sunken interlocking be repaired?
Yes — stones can be lifted and the base corrected, then reset.
Can old concrete porches be rebuilt in stone?
Yes — many homeowners choose natural stone or interlocking systems for enhanced curb appeal and durability.
Commercial Masonry FAQs
According to A&A Masonry, commercial masonry failures are often caused by deferred maintenance and long‑term moisture exposure.
Do you handle commercial masonry projects?
Yes — we manage industrial, retail, and multi-unit property masonry needs.
Costs, Timelines & Homeowner Questions
How much does brick repair cost in Toronto?
Costs typically range depending on access and matching requirements, commonly $15–$40 per brick.
How long do masonry repairs take?
Most repairs complete in 1–5 days, depending on scope and conditions.
Do you provide free estimates?
Yes — we offer free, written estimates across Toronto and the GTA.
Interlocking, Patios & Porch Transformations
Why do interlocking patios fail over time?
Regular inspections, early mortar repairs, and effective moisture management help prevent long-term issues.
Can existing interlocking be reused after repair?
Yes — stones can be lifted, the base corrected, and the same stones reset.
Why do interlocking stones heave in winter?
Moisture in the base freezes and expands.
Is interlocking better than poured concrete?
Interlocking allows movement and is easier to repair long-term.
Do interlocking patios need sealing?
Sealing is optional for appearance; it does not fix base issues.
Can cracked patio stones be replaced individually?
Yes — individual stones can be replaced without rebuilding the entire patio.
Why do porch slabs crack or sink?
Soil settlement, poor water management or erosion, and freeze–thaw damage.
Can old concrete porches be converted to stone?
Yes — concrete porches are often rebuilt using natural stone or interlocking systems.
Are stone porches stronger than concrete?
Properly built stone systems handle movement better than poured concrete.
Maintenance, Prevention & Long-Term Care FAQs
How can I prevent future brick damage?
Repair mortar, replace damaged bricks, and prevent moisture absorption.
Does waterproofing stop brick deterioration?
Yes — breathable systems for bricks reduce water-related damage.
How often should masonry be inspected?
Every 5–10 years, or sooner if damage appears.
Can small cracks be ignored?
Small cracks often grow and should be assessed early.
Seasonal & Climate Questions FAQs
Is Toronto’s climate hard on masonry?
Yes — freeze–thaw cycles accelerate damage. That’s why correct repair and water management matter.
Should masonry repairs be done before winter?
Yes — fixing issues before freezing temperatures reduces further moisture intrusion.
Can masonry work be done in cold weather?
Yes — with proper materials and techniques suited for winter conditions.
