Concrete canopy removal

How far back are you planning to take it?
Is it acting as a lintel for the bricks above

 

Bit out of my knowledge, but it would lose strength by cutting it back. I'm sure one of the builders will be able to confirm if it's likely to be an issue or not

 

How far does the concrete canopy extend inward? looks like 3/4 brick length.

If the concrete doesn't extend into the inner leaf of the house, then you will considerably weaken it by cutting it flush, it will be reinforced with steel rebar.

The other option is to remove it completely and install a lintel, maybe a sing leaf catnic.

 

I would completely remove it and fit a concrete lintel in its place, I'm assuming your putting a porch up spot will be hidden.

 

Wishful thinking...

And the chances are you would get away with it.

But the folks on here won't say "yeah - do it!" unless they know for sure it'll be ok.

Sadly it doesn't look as tho' anyone on here has come across that kind of setup before.

Any chance of a photo of the top of the canopy, where it fits into the brickwork?


Anyways, until you know for certain, it'll chust have to be your call. Very likely you will be able to cut it nigh-on flush and your house won't fall down.

But we'll all come round to do a 'Nelson'* if it does...

run a cut level with house , then bolster it off bit by bit

 

All this chop it off bit by bit or even cut straight through it isn't going to work if you are putting that canopy up you posted, it will at best look shiit and at worst end up with concrete cancer where you have cut through the reinforcing steel and moisture creeps in causing rust which in turn explodes the concrete from the inside out.

Fitting a new concrete lintel will still not look that good due to being on show,but at least it will be weather proof.

 

i concur didnt realise it was going to be on show

 

Ooooh - good point, Phil.

I guess it could be painted a neutral colour to disguise the cut edge (matt black...), but - yes - the exposed rebar ends would need sealing effectively.

 

Remove similar concrete canopy over my back door a few years ago, ended up competely removing it & replacing with a single leaf cantic lintel, as the rebar was about 150mm in from the edge of the slab, so no use as a lintel to support above brickwork..
