Can ESI Waterproofing & Masonry Restoration, Inc. match existing brick, stone, and mortar on historic buildings?

ESI Waterproofing & Masonry Restoration, Inc.specializes in historic masonry restoration for commercial, institutional, municipal, and condominium properties throughout Massachusetts and New England. Successfully matching existing brick, stone, and mortar is essential to preserve the architectural character and structural integrity of historic buildings, especially given New England’s challenging climate and freeze-thaw cycles.

Our process begins with a thorough site inspection and documentation of existing masonry materials. ESI evaluates the age, type, color, texture, and composition of the original brick, stone, and mortar. This analysis often includes historic research and laboratory testing where appropriate. Sourcing period-appropriate or custom-fabricated materials may be necessary to replicate the original appearance, especially for properties governed by historic preservation guidelines or local review boards.

Mortar matching is particularly critical, as improper mortar selection can cause damage to historic masonry during cycles of freezing and thawing. ESI selects or formulates compatible mortar mixtures to match original strength, permeability, color, and finish while supporting weather resistance and long-term performance.

Proper installation, including joint tooling and curing methods, helps ensure new and existing masonry perform well together, managing moisture and minimizing risk of water infiltration. We follow industry best practices and use materials approved for historic work. ESI’s team understands New England weather patterns, salt exposure, and the impact of seasonal moisture on building envelopes.

An ongoing maintenance plan is important to extend the life of restored masonry and maintain both appearance and building protection. If you’re considering facade restoration for a historic or architecturally significant property, a professional inspection and planning process is the best way to ensure a durable, historically accurate result.
