does it all need doing? what are you doing yourself?
replastering...cheapest thing to do is buy yourself an SDS drill and chip oif yourself. Blob and dab plasterboard and then just get a plasterer to skim. is expensive if you get professionals, about 300-500 quid plus per room
rewiring, if you are chipping of plaster, can you or your dh not wire and insuklate the rooms and just get an electrician to fit the consumer box? Professional job about 2k for an average house
with a guarentee
dmap proofing is charge by thesquare metre. Our was 645 quid recently but ours is mid terrace, a semi would be dearer
doubleglazing, depends on how many windows..can be anything up to 10k. can the old windows not be salvaged?
a new bathroom fitted by a plumber, you are looking at 1k just for a 'basic' job
kitchen, I'd say if you want it fitted at least 5k, allowing for evrything
central heating, average house is 2.5k - 3.5k
re-roofing, we have slate it is expensive. We are in a conservation area and have to keep it, how about you?
ventilation grill, you should be able to do yourselves
repointing and roughcasting, unsure dh did ours. 2 quid for a bag of mortar mix......so not expensive just tedious, but we had a quote for the front of our house and it was 1.2 k
floorboards, not sure. We replaced a floor in our old house and it cost 120 quid but dh did it. Here we have paid for timber treatment instead in the basement, but will have to find flooring to put oin it obv
I am not an expert at all, just have bought alot of run down properties over the years
