Speweik Preservation Consultants, Inc., collaborates with architects and building owners nationwide in the preservation of historic masonry architecture. Our team of European-trained heritage masons bring the experience necessary to establish a logical and comprehensive approach to specifying solutions that are based on time-tested traditional materials and performance. We are a hands-on non-contracting company that understands historic masonry construction techniques.

We respect the original workmanship integrity of historic masonry architecture. We understand the challenge architects, building owners, and government agencies all face – the lack of qualified masons. Speweik Preservation has developed a sequential systematic approach to providing our clients a better way to deliver a successful historic masonry preservation project.

Our approach includes:

1. Condition Assessment/Survey & Material Matching

2. Drawings/Specifications & Historical Research

3. Quality Assurance Test Panels (Installed Prior to Bidding)

4. Evaluate Bidding Masonry Contractors

5. ASTM E2659-09 Historic Masonry (on-site) Trade-Skill Worker Training

6. Quality Assurance Construction Observation Inspections

ASTM on-site training services designed to protect your project from poor quality and sub-standard workmanship in the low-bid environment.

The Secretary of the Interior’s Standards for Rehabilitation: The Standards (Department of Interior regulations, 36 CFR 67) pertain to historic buildings of all materials, construction types, sizes, and occupancy and encompass the exterior and the interior, related landscape features and the building’s site and environment as well as attached, adjacent, or related new construction. The Standards are to be applied to specific rehabilitation projects in a reasonable manner, taking into consideration economic and technical feasibility.
