3.1.4 Materials • Any repairs or renovations to heritage buildings or generally historic buildings, within the Central Area, should include materials similar to those found within original building facades. Masonry • Existing brick should always be retained when possible. • Brick and masonry repair should be undertaken using proper heritage materials and methods. • When possible, painted brick should be uncovered to expose the buildings original character. • Cleaning of buildings should occur in a non- destructive manner. Sand blasting and high pressure water blasting or excessive acid washes should be prohibited. • Replacement brick should be carefully selected to ensure its colour and texture is complimentary to existing brick.
• Suburban ‘buff’ brick or salmon coloured brick is not acceptable. • New brick size and configuration conform to proper masonry units. The use of brick veneer is not acceptable. • When necessary, original masonry joints should be repointed to inhibit the entry of water and ice into the wall system. • Removal of old mortar should be performed with hand tools only. Appropriate lime mortar mixes matching original colour and sand, lime formula should be used. Modern mortars cause damage to older masonry. • Spalled stonework can be restored using professional epoxy-based fillers. For larger repairs, replacement stone may be required. Replacement stone should be selectively sourced to ensure a consistent match with the original stone. Use of precast concrete to replace stone is discouraged. • In some cases, existing brickwork can be treated with a masonry stain. It is recommended that the owner consult an architect, heritage consultant or the Tillsonburg Architectural Conservation Advisory Committee to deem whether the use of masonry stain is appropriate, and if so, which stain colour should be applied. Wood • Wood should be repaired rather than replaced whenever possible. Replacement, if necessary, should use the same species of wood. Windows / Glazing • Windows should be preserved where possible. • Replacement windows should duplicate the original in style, type and material.
Existing brick should always be retained where possible.
