About Us

The Thompson & Lichtner Co., Inc., an American women-owned small business (WBE-SDO), offers a broad range of engineering, testing, quality control, advisory, building envelope, and forensic services to the construction industry, particularly in areas of weatherproofing, moisture penetration, and air and water penetration.

Our services are supported by a full laboratory facility located with our office in Canton, Massachusetts. We are committed to helping our clients achieve professional objective engineering and testing solutions to construction problems and assure independent, effective quality control during the construction or repair of new and renovated buildings. For 127 years our success in the fields of engineering and testing has depended on the diverse capabilities and extensive experience of our staff, which includes individuals with education and experience in civil engineering, architecture, and materials science.
