Frequently asked questions
How do I check a mold pro's licence in Valley Stream?
Look the name up in the NYS DOL records and ask for the licence number in writing. Each listing here shows the licence numbers from the agency's records. The Valley Stream hiring guide lists questions to ask.
How much does mold inspection cost in Valley Stream?
National HomeAdvisor figures put mold inspection or assessment at $303–$1,075 (average about $689) and mold remediation at $1,223–$3,757 (average about $2,368). There are no Valley Stream-specific prices, so get written quotes. See the cost guide and estimate tool.
Can the same company test and remove mold in Valley Stream?
No. In New York, the company that assesses your mold can't also remove it on the same job, so get assessment and remediation quotes from different licensed firms.
