Down Under Environmental has been doing residential environmental testing since 2004.  We conduct accurate, high-quality and affordable sewer scope inspections, radon testing and underground tank searches in the Greater Portland Metro area.

At Down Under we pride ourselves in delivering responsive, friendly and professional customer service and same-day computer-generated reports.  Because we don't do repairs, there is no conflict of interest in our work.  We are unbiased and our inspections​, testing and reporting is accurate and honest.

We hope that you will find what you are looking for on our website.  Please call or email us if we can answer any questions that you may have, and we look forward to being of service to you.
