Water softeners, well water treatment, radon mitigation and mold testing are jobs worth getting more than one price on. Tell us a little about your home and we'll connect you with installers serving your area.
Typical costs
- Water softener, installed: $1,000-3,000 depending on size, plumbing and drain access.
- Well water treatment: depends entirely on what a certified lab test finds (bacteria, iron, sulfur, arsenic, nitrate). Get the test first, then compare systems.
- Radon mitigation: $800-2,500 for most single-family homes, plus a follow-up test.
Questions to ask
- Are you licensed, and certified for radon (NRPP or NRSB) if relevant?
- For a well: which lab results is this system sized to treat?
- What size unit, and why for my household?
- What is the yearly maintenance cost?
- Is a post-install test included?
