Hi. I'm a bit perplexed about the quotes I'm getting for some external rendering work so wondered if I'm missing something.
I have a garden wall of concrete block, 9m x 1.6m so approx 15 sq m. I've also got the back of my brick built extension, 4.6 x 2.9 so call it 14 sq m. The door and window take out 5 sqm so let's say the job is 24 sq m in total.
Using online calculator for materials, I'm estimating two coats at £125 per coat for a 16mm 5/1/1 sand/cement/hydralime mix plus plasticiser.
Then there's the external beading round the windows, doors and corners which I've calculated at 18m. £6 per metre seems to the ball park price.
So that brings materials to £250 for the render and £108 for the beading. Would I need horizontal beading too? Either way it's only going to add another £100 to it. So materials approx £350-£400?
Therefore I'm wondering how one quote can be £3,300, another £1,700 and another £1,400. I don't know how long the job would normally take but based on the £1700 bloke saying he and his colleague would get it all done in a day I'm thinking there's a generous day rate in there even for London's standards. Is there something I haven't taken into consideration? It's a one storey flat roof extension so I wouldn't have thought scaffolding was necessary. The extension is bare brick, the concrete block wall has been painted with masonry paint. Thanks.
