What services does Stone & Trowel provide for heritage buildings?
We specialize in heritage masonry restoration and conservation across Vancouver Island and the Lower Mainland. Our core services include:
• Detailed masonry condition assessments and heritage consultations
• Heritage repointing using compatible lime-based mortars
• Masonry cleaning (biological growth, grime, graffiti) with low-pressure, non-abrasive DOFF Integra and Torc systems
• Brick and stone repair, replacement, replication, and rebuilding (including chimneys, parapets, facades, and carved features)
• Stabilization and long-term maintenance planning for historic structures
These services are tailored for municipalities, institutions (churches, schools, cultural centres), strata councils, property managers, and private owners of heritage or character homes.
Why is traditional lime mortar used instead of modern cement mortar for repointing?
Historic buildings were typically built with lime-based mortars, which are softer, more flexible, and “breathable.” This allows moisture to evaporate naturally, preventing trapped water that can cause spalling, cracking, or damage to soft brick/stone. Using incompatible modern cement mortars can trap moisture and accelerate deterioration. We test existing mortar and create custom lime-based mixes (often hot lime or natural hydraulic lime) to match the original in composition, strength, and appearance—ensuring longevity while preserving the building’s historic integrity.
What does a typical masonry assessment involve?
A heritage masonry assessment is the essential first step for any restoration project. We conduct a thorough on-site walk-through to evaluate structural integrity, surface issues, and underlying problems. This includes:
• Photo documentation and detailed condition reporting
• Mortar sampling and compatibility testing
• Photogrammetry for precise analysis of hidden conditions
• Recommendations for scope, phasing, and long-term maintenance
We then provide a clear report and collaborate with you, architects, engineers, or heritage consultants to develop a tailored plan.
How do you clean heritage masonry without causing damage?
We use specialized, low-pressure steam-based systems (like DOFF Integra and Torc) that align with Heritage Conservation guidelines. These methods are gentle, chemical-free, and non-abrasive—removing moss, lichen, grime, graffiti, or weathering discoloration without saturating or harming the stone, brick, or mortar. We avoid high-pressure washing or harsh chemicals that could erode historic materials.
What kinds of projects has Stone & Trowel completed?
We have extensive experience with landmark and private heritage structures, including:
• Government House (stone retaining walls repointing and cleaning)
• Craigdarroch Castle
• Ross Bay Cemetery
• Parliament Buildings
• Duncan City Hall (1913 sandstone and brick restoration)
• 17th-century limestone features at Oldfield Estate
• Numerous Samuel Maclure-designed heritage homes (chimneys, stone pillars, retaining walls, brick facades)
Our work spans public civic buildings, institutional properties, and private estates throughout Victoria, Saanich, Duncan, and Vancouver Island.
How long does a heritage repointing or restoration project take?
Timelines vary based on project scope, building size, weather, and access. A chimney repoint might take a few days, while full facade work on a large heritage building could span weeks to months (often phased to minimize disruption). We provide realistic estimates during the assessment and keep you updated throughout with step-by-step progress reports.
Do you work with heritage regulations and municipal requirements in Victoria/BC?
Yes—absolutely. We follow best practices from heritage conservation standards and collaborate closely with municipal planners, heritage architects, and engineers to ensure compliance. Our methods prioritize minimal intervention, material compatibility, and preservation of original fabric, helping meet requirements for designated or character properties.
