    Repairing sandstone pillar on bay window

    Using concrete or any other non porus media will likely make the situation worse. I used lithomex on my own house for similar problems. Its used a lot up here on historic buildings.

    boiler exhaust fumes through party wall

    Thanks Gents, I am unconvinced that the flume is the problem. It is actually about 1' above the level of the patio doors and has a small flume management kit on it (pointing upwards at 45 degrees). The plume seems to direct well upwards. the guy next door is friendly enough at the moment but can...

    Stonework

    whatever you do... don't seal it. All that will likely happen is that water will get trapped behind the seal and freeze, speeding up the decay. I've seen lithomex used with some sucess in these cases. it's Used on historic buildings. http://www.stastier.co.uk/lithomex/lithomex-data.php

    Fixing up sash windows

    I agree with fox on the cill. better to splice in a piece. However I would knock out that cement on the join between the brickwork and the frame and fill with sand mastic. http://www.masonsmortarshop.com/traditional-burnt-sand-mastic-5-litre-tub.html

    Valliant ecotec problems

    Update; I got hold of a 15-60 (grundfos alpa pro) pump and took off the pump which had been in place for a couple of weeks. to my surprize there was a lot of scale in the pump. Black metallic magnetic particles. I now think that the heat exchanger is likely to be full of this stuff hence the...

    Valliant ecotec problems

    So it's not the pump! i changed it. The old one had some scale in it but not a lot. I had a heating engineer out yesterday. I wasn't in but he spent about 4 hours sussing out the system then derating the boiler to 10kw and claiming sucess. my house is pretty big (4000sqft) and the house is...
