Answer 1

Read daddy-bear's response. He has it totally together. But the comedians are worth a laugh and it was an hilarious series

Answer 2

We bought an old cottage (1870) and the first thing we noticed was in the dining room which had wood panelling half way up the wall had a white V shaped mark in the corners of the room. It started at the bottom going up the wall. Like you we knew it was damp and not sure if it was rising damp or what. We got in 3 builders (one was a friend or ours) and they all agreed it was not rising damp but condensation cause by inadequate heating and lack of ventilation. The double glazed units didn't have opening vents in them and the radiators were not adequate for the size of the rooms. During the winter it was never a problem as the heating was on and kept the damp at bay but when summer arrived it appeared. After a couple of year when we could afford it we changed our heating system from LPG to Oil and got in a new boiler and upgraded all the radiators to proper sizes for the rooms. We then changed the double glazing to windows with air vents and since then have never had anymore problems with condensation. If I were you I wouldn't do anything in a hurry. Get all the information you can and don't feel forced into anything until you are sure what the problems are.

Rising damp comes from the ground up and is more usual in older houses before damp proof courses and Portland cement become the norm.Damp creeps up the brickwork, like a wick.
Penetrating damp can come from the outside of a wall through to the inside, If the brick is porous or problems with wall ties etc or the cavity wall is bridged or non existant. Also lack of adequate ventilaion under the floor can be a problem
Lots of companies specialise in this type of work and usually give a 20yr guarantee.

Answer 4

Rising damp is damp that travels up your wall from the earth below, this will usually be due to an ineffective DPC (damp proof course) or a lack of one altogether.
Penetrating damp travels through a wall from things such as high ground levels, defective rainwater goods, roof problems etc.
The solution to these problems is completely different in either case. There is an excellent website with full answers to these problems and a guide to their correction listed below.
