External Flue and Condensate Drainage Installation, Shepherd's Bush W12

External boiler flue installation was completed in Shepherd's Bush, W12 this week. After core drilling through the external wall and fitting the concentric horizontal flue terminal, the surrounding masonry was repaired with a fresh, smooth cement and sand render patch, integrating cleanly with the existing textured pebble-dash facade.

Finished properly, inside and out

A correctly sealed flue penetration prevents damp ingress, pest entry, and cold air infiltration into the property. We don't leave a rough hole in your wall — every flue installation we complete is finished to a professional standard both inside and out, matching the existing facade rather than leaving an obvious repair patch.

Getting the condensate drainage right

The black condensate discharge pipe was routed from the boiler through the external brick wall, with professional mortar applied around the penetration to seal against weather and pests, terminating at ground level safely into the drainage point. A condensate pipe that is incorrectly installed, too exposed to frost, or blocked will cause the boiler to shut down in cold weather. If your boiler stops working in winter and shows a fault code, a frozen or blocked condensate pipe is one of the most common causes.
