The Collaborative maintains one of the few private laboratories in the United States for the evaluation of historic paint, mortar, and plaster. Through the evaluation of historic materials, the firm is able to recommend replacement materials that are hisorically appropriate, and archival. In cases where the condition of building system is concealed, a borescope is used for remote visual inspection. This offers the unusual combination of speed, accuracy and low cost in evaluating the condition of building systems and materials. Contact us with your project specifications.
