BEFORE YOU BOOK
Water testing questions
Do you test public water and private well water?
Yes. Tell us which water source serves the property so we can confirm a suitable testing scope. A household sample measures the selected items at the sampled location and time.
Can I arrange water testing with a rental inspection?
Ask when you book. We’ll confirm whether sample collection can be coordinated with your rental or lead inspection and any preparation needed.
Which tests do I need?
Choose based on your water source and any property or lender requirements. Compare the included tests above, or call for help. No package tests for everything.
Can I request individual or paired tests?
Yes. Ask for lead and copper, coliform and E. coli, a single test, or another combination. We’ll confirm pricing for your request.
How do collection and results work?
Contact us before collecting a sample. We’ll confirm preparation, containers, collection arrangements, and the expected lab turnaround.
