Commercial fridge gasket replacement: a mouldy seal is a health inspection finding
A torn magnetic gasket on a fridge door lets warmth in, the door fogs up, mould grows along the edge and the health inspector writes it down. You arrive with a made-to-measure gasket, replace it right in the kitchen and log every refrigerated door in an overview.

You offer replacement of magnetic door gaskets on reach-in refrigerators and freezers, under-counter fridges, display cases and walk-in coolers in restaurants, hotels, canteens and shops. You measure the door, order a made-to-measure gasket with welded corners or use a common profile from stock, replace it and check that the door closes properly. In the US entire franchise networks are built on this narrow service, because gaskets in a busy kitchen wear out faster than anyone expects and the original part from the fridge manufacturer often takes weeks to arrive. The replacement doesn’t touch the refrigerant circuit, so you don’t need an F-gas certificate for it. The catch lies elsewhere: a leaking door often doesn’t have a faulty gasket but loose hinges or a sagging door, and a new gasket then leaks just like the old one. Whoever can spot that and adjust it wins.
Almost every kitchen has a fridge whose door swings open by itself, that ices up or that drips condensation. The culprit is usually a torn or hardened gasket. The fridge then runs almost non-stop, the temperature inside fluctuates and black mould grows in the folds of the rubber.
💡 Why it works
🧫Mould in the gasket is a finding
A torn or hardened gasket can’t be kept clean and mould grows in its folds. The health inspector sees it at first glance and the operator has to deal with it.
