Cast-iron sectional boilers are built to last — and often the smartest move is to rebuild rather than replace. RK Hunter performs section-by-section replacements across North and South Carolina.
A cracked or leaking section doesn’t always mean a whole new boiler. Replacing individual sections restores the boiler to reliable service and can extend its life for years at a fraction of the cost of full replacement.
We assess the boiler, isolate the failed sections, and replace them — then re-test and re-commission so the unit runs safely and efficiently. Where a rebuild no longer makes sense, we’ll tell you honestly and lay out replacement options.
We pair proven Weil-McLain cast-iron sectionals with Webster combustion burners for dependable, serviceable heat — a combination we install and maintain throughout the Carolinas.


We’ll evaluate your boiler and recommend the most cost-effective path.
