Nothing much to add, except that each fireplace has its own flue, so if the upstairs bedroom has - or had - a fireplace, this will have a flue, and if unused, there may be condensation or even penetrating rain.
a good roofer knows what an overhaul is. There will be old cracked, slipped and missing tiles to replace; if they were just held on with nails some of the nails will have rusted away, if they have nibs, some of them will have slipped when the nibs broke off or the battens rotted. There will be leadwork to renew, or flaunching round chimneys. Ask around for recommendations, and look at samples of their work. Also drive round the area looking for people who are having their roofs mended or renewed, or have obviously new roofs, ask the owners what they thought and take details of the roofer. It might be worth re-roofing which will cost more but last longer and lead to a cleaner, drier loft. Round here we use stainless or bronze roofing nails because it is coastal, they might still use galvanised in your area, which will go rusty after a few years.
Any wiring more than three years old will not meet current standards because they keep changing. That does not necessarily mean it is unsafe, but it is very likely to have unsufficient sockets, especially in the kitchen. Again get recommendations for a local electrician; when phoning, ask what Competent Person scheme he is in, and how long he has been a member, and write it down so you can check on their website later. Ask if he is a Domestic Installer, this is the lowest grade of membership and not well thought of in the trade. You might be OK with an upgrade, if it is more than 40 years old it will need rewiring, anywhere between, see how much work it needs. A rewire costs the same as a second-hand car.
Damp might be due to the ground or a patio having been built higher than the original ground level. If so dig it back and open up the airbricks and possibly add extra. It might be due to leaking pipes or drains or gutters. It is very seldom anything than a chemical injection will cure. A trusted local builder will have seen it all before.
Disused flues need to be ventilated top and bottom or they will get condensation inside. This usally leaves a distinctive yellow or brown stain from the old soot and tar deposits.
We are (hopefully) buying what should one day, with lots of saving and hassle some tweaking become our dream house. The survey is back today, and it has come back with a few things I'm a bit worried about (classed as 'urgent repair needed'):
1. There are some broken tiles on the roof and it needs 'overhauling and repairing'. What is classed as overhauling?! Not sure if they mean replacement!
2. The electrics don't comply with modern standards and it needs rewiring. How much is this likely to cost? (3 bed detached with living room, dining room and kitchen)
3. There is damp which they reckon is caused by a bridged or deteriorating damp proof course. I have NO idea how much this would cost...
4. There is also a bit of damp in the upstairs bedroom which they think is coming from the disused chimney flue (which confuses me because this is directly over the living room, which has a multi fuel stove).
We've got it for £12.5k under the asking price, and the vendors (who are lovely) only accepted this on condition that the only bit that was subject to survey was the roof. So, presumably we can't ask them to drop the price.
Any advice / estimates would be greatly appreciated!!
