Internal Damp

[jrb]

If it is low level and happening at internal walls as well, it is more likely to be a dpc issue, or poor solum venting, or a combination of the two.

You can only go off reviews and hope most of them are genuine.

I'll give them a call. Hopefully they can sort the damp out, as well as replastering the wall.

Check the leading around your chimney, worth checking first

Take the chimney down. Had all those issues, leading checks, repointing, done it all.

Water will always find a way.

Had the chimney removed (we have central heating anyhow)

Roofer tiled right over the void in a day.

Never had an issue since.

When it comes to damp, you need a proper independent damp report done. You will need to pay for this report. It is 99% likely not to be rising damp. Water doesn’t just magically levitate up your walls.

Do not get some builder round and get him to ‘diagnose’ the issue. Get a report done then give that to a damp specialist to fix the issues.

I have used this company for my surveys in the past.

Thanks.

I'll start will the least expensive option first, a replaster and a piece of new skirting board. If that doesn't show up anything I'll get somebody to inspect the chimney and the flashing. Hopefully i can find somebody honest and I don't get ripped off for work that doesn't need doing. It's impossible to know if work really needs doing or not unless I go up on the roof myself, which I can't do.

that would be one of the last things I'd do as it's not solving anything, also stop wasting money on paint as well until it's solved. Rule out the chimney first. Flashing, pointing, cap, damaged bricks, it could be any of these. Don't you have a drone? can you do a video of the chimney to see the state of the flashing? not sure if the video will be good enough but worth a try

99% of internal damp issues are down to poor ventilation coupled with high humidity, so if you have any cold spots on the walls you will almost definitely get patches of damp. Cold spots can be down to many things, and one of the biggest culprits is poorly installed cavity insulation, and after that bridging between the inner wall and the outer wall. In older houses such as yours the gap between the inner and the outer wall is usually narrower than more modern houses, so bridging can often occur when you get mortar bridging the gap.

With an internal air temperature of 19 degrees and a relative humidity of 65%, any surfaces in your house that are 12.3 degrees (the dew point) or lower will form condensation. At 80% humidity that dew point rises to 15.5 degrees.

Ventilation is always the key. Make sure windows are open in the day, drying washing indoors without ventilation is always a problem too.

Ventilation is always the key. Make sure windows are open in the day, drying washing indoors without ventilation is always a problem too.

If you can get the humidity down to 55% or below and keep all the internal surfaces above about 10 degrees then there shouldn't be any internal damp from condensation.

The problem is with internal damp from condensation is once it penetrates the plaster it tends to remain wet and readily soak up more moisture which is where people often mistake it for penetrating damp.

How much did that cost you? Obviously prices will have changed since then if it was a while again.
