⚠️ PREVENTABLE BOILER DAMAGE CAUSED BY LACK OF MAINTENANCE ⚠️

As shown in these images, a hole developed in the top of this commercial boiler casing due to ongoing water leakage and a lack of professional preventative maintenance. The issue was caused by a perished rubber seal inside the commercial flue, allowing acidic condensate water from the boiler to leak onto the casing and gradually cause severe corrosion and rot.

Regular servicing and inspections are essential for commercial boilers, helping to identify worn components before they lead to costly breakdowns and major damage.

Out with the old, in with the new 🔧🔥

This Glow-worm boiler installation was carried out after the previous unit finally gave up after 15 years of service. With tenants left without heating and hot water, a fast turnaround was essential.

Our team acted quickly to remove the old system and install a reliable new boiler, getting everything back up and running with minimal disruption.

When it matters most, we deliver.
