Protecting homeowners since 1999
Septic systems and oil tanks are all we do — twenty-seven years of it, and more than 500,000 policies written. No general home warranty with a tank clause bolted on.
- Insurance-backed
- In-house claims team
- 12 states

One thing, since 1999
ProGuard started as a family-owned business with a single product: a residential cleanup and replacement program for heating oil tanks. Septic system coverage sits alongside it now. Twenty-seven years on, that is still the whole business — not a tank clause bolted onto a general home warranty.
The focus is the point. Our claims team recognizes a failing leach field or a water-ingested tank straight away, because it is the only thing they look at. We run every layer ourselves — the coverage, the enrollment, the billing, the claims and the contractors — across the twelve states we cover, so a failure is one call rather than a hunt for someone who will take the job on.
You may know us as Powderhorn Agency. The name changed to ProGuard; the plans, the people and the service did not.
Backed by an A.M. Best A-rated insurance carrier, ProGuard gives homeowners reliable protection for their heating equipment, oil tanks and septic systems — before small problems become costly disasters.
Who runs ProGuard
Behind that sits the part customers actually meet: our own claims team and a vetted contractor network across the twelve states we cover.
