What is Oil Tank Replacement?
Oil tank replacement involves removing your existing heating oil tank, safely disposing of it, and installing a new unit that meets all current safety, environmental, and insurance standards. Whether your tank is above-ground or underground, indoor or outdoor, we ensure every step is completed to the highest professional standards.
Modern oil tanks are designed for durability, leak prevention, and efficiency. At Armus Mechanical, we work with trusted brands like Granby and Roth, offering double-wall tanks and corrosion-resistant materials that provide decades of reliable service.
Signs You May Need an Oil Tank Replacement
Knowing when to replace your oil tank can prevent costly emergencies. Watch for these warning signs:
-
Tank Age – Most tanks last 15–20 years; older tanks are at higher risk of leaks.
-
Visible Rust or Corrosion – Weak spots can quickly become leaks.
-
Fuel Odors – Persistent smells of heating oil often signal a leak or venting issue.
-
Sludge Build-Up – Sediment can clog fuel lines and reduce system efficiency.
-
Insurance Company Notices – Many insurers now require proactive tank replacement.
If you notice any of these issues, it’s time to schedule a professional inspection.
