Got black marks around / above window frames in 2 bedrooms. What action do i take please? Get a damp co in? Get something from B & Q? Thanks. Up the O's!

Inside? What room is this in? Water in the air will be drawn to the coldest surface, probably the area you talk about because i would guess when the windows were fitted they didnt fill above the area properly.

This sounds like black mould caused by condensation. Do you dry clothes indoors or know what the source of the water could be?

Rising damp would come from the ground upwards.
Penetrating damp would come from a water source leaking onto an area, like a leaking gutter or pipe.

We live in a town house. It is in 2 bedrooms on the top floor. We use a tumble dryer so no clothes dried indoors. House built 199o generally good condition

Open windows in all levels. Consider getting an air brick installed.

Short term you can get anti mould paint from most places. Go over it but it will probably return if there isn’t decent airflow.

Get a dehumidifier too

Best get a convertible roof too.

Most damp trades people are bandits in my experience. They try to flog you expensive, invasive treatments that don't deal with what is normally the main issue, which is a lack of ventilation. Air bricks, passive air vents and air vent tiles will deal with most problems. But you might have water ingressing from somewhere so worth getting someone into look.

I would get the roof and gutters checked if i were you. Have a look from the outside if you can, particuarly if its raining, you may be able to see if something is dripping onto that area.

I'd get your pointing checked out, do the same with flashings if you've got them

This.
School friend of No. 1 daughter works for a "Damp" company. I remember him saying that there work would be cut in half if people opened windows more to let air in and out and circulate. On the other side is, if you do that and get burgled, the insurance company won't pay up.

This is why most windows now come with trickle vents

Just had a thought- not somebody vaping indoors is it?

Clean the mould with a water/bleach solution as said before if airing drying clothes open windows if not always leave a least one window on a vent or a vent open if old type plastic window frames you can attached an air vent yourself.

I live in a 300 odd year old house and my missus is obsessed. Could be -5 outside and the windows are open

Can Cavity Wall Insulation Cause Damp Problems ?

Yes

It can also affect the ability to secure a mortgage against the property.

Stick an air pump in your loft to throw fresh air in from outside, forcing the damp air inside the house out.

Simply use a crane to put your house on a plethora of roller skates, and roll it down to sunnier climes.
