Some Notes about Fees

The PDDC will make every effort to keep the cost of a diagnosis as low as possible.  Fees help cover the cost of equipment/supplies/labor needed to process a sample, but not covered by state or federal funds that the PDDC receives.  Fees also help support PDDC outreach programs throughout Wisconsin. 

 Please feel free to contact the PDDC to discuss possible tests and associated fees for your specific sample prior to submission.  If no specific testing requests or cost limitations are noted at the time of submission, the PDDC reserves the right to determine which tests are most appropriate for a given sample.

 In most instances, the fee for homeowner samples will be $50 or less.  Fees for most commercial samples will be $100 or less.  However, exceptions may arise. 

 Please *DO NOT* enclose a payment with your sample.  You will be billed for any work after your analysis has been completed and at the time that your report is sent to you.
