Kitchen Fitting

Drilled into lintel trying to install kitchen extractor fan

Anonymous user 6 March 2024 - 2.31 PM

I'm having a new Kitchen Extractor Fan installed which is to be externally vented. It appears the builders have core drilled through the edge of the lintel and a bit of steel is showing. I have searched this website and aware you should 'not' drill through lintels. My question is.... if the builders have drilled through the edge of the lintel can it be repaired and how? Info which may help .... Its 1950's 3 Bed House (previously a Council Property) Concrete and Steel lintels Window has been moved and is approx 300 mm away from edge of the drilled hole. The solution the builder suggested was to insert the reducer ducting through the wall as he couldn't core drill anymore to enable him to fit the pipe through (hope that makes sense) Is there anyway I can upload pictures on here ??? Be grateful for any advice please, Thank you

Are you a tradesperson and able to answer this question?

Hi there, This sounds from the description like he's just taken out a chunk of the edge of the concrete lintel with rebar, if the cored hole is 300mm away from the point of load ie a window opening everything will be fine, current building regs stipulate a lintel should over hang by 150mm and 1950's council built properties are known to builders to be of top quality builds - so perhaps they used to bed lintels in at 300mm overhang. Most builders would assume the lintel wouldn't go past beyond 200mm next to the opening. It's difficult to say for sure without photos but I feel confident everything will be fine. A structural engineer would be your best route for absolute peace of mind. Hope this helps.
