Grinstead Insulation

Grinstead Insulation offers closed-cell spray foam and includes crawl spaces and rim joists among the applications on its company website. The published phone is 317-339-7025. Its company profile identifies Indianapolis, Indiana as headquarters and describes work across Central Indiana. Ask whether the proposed crawl-space project fits the company’s current service scope. Request the foam product, intended surfaces, preparation steps and access arrangements in writing. Confirm whether removing existing insulation is included and whether any separate liner or water-management work is needed. The company’s advertised spray-foam application does not establish every component of a full encapsulation project. This listing follows the company-published Indianapolis headquarters locality. Other business directories contain differing locality details, so a street address and map pin are not supplied. Confirm the property’s coverage and any visitor arrangements directly rather than treating older Greenfield references as another office. Company-published information was reviewed October 17, 2026 using indexed or cached text. Public walk-in access, credentials, contact reachability, availability and workmanship have not been independently verified.
