Before You Call Greenlight Inspections LLC

1. Do you also do remediation? If so, who checks your work?
2. How many air samples will you take, and will you take an outdoor control sample?

Ask for a Maryland Home Improvement Commission license number and look it up with the state. Also ask for proof of insurance, industry certification for the restoration crew and lead safe certification for any pre-1978 home.

They list no storefront. Ask where the business is based and whether the crew is their own.
