Humidity - Should I be worried

melissashopping

Last year I bought 2 Canary home security cameras, which also monitor air quality, temperature and humidity. Since the summer the humidity in the house has gone up. This is normally a very dry house and was around the late 30s to mid 40% humidity when the central heating is on in the autumn/winter.

I am now getting figures during the day into the early to mid 60s and into the 70s, then at other times in the late 40s to late 50s. We have the doors and windows open most of the day as I work from home. I did not see this as a problem until someone told me that this was too high, I just assumed it was due to the time of year, and that the humidity in winter was lower due to the heating being on and the doors closed.

There is no condensation on our double glazing, mould, any signs of damp, guttering good condition, pointing on house good condition. We just had 2 rooms refurbished and walls skimmed, decorated, no trace of any problems, roof is in good condition and no leaks. Everything feels dry and we have had no damp patches or anything to worry about.

Is this due to the time of year? or should I buy a hygrometer to see if the readings i am getting are accurate.

Don't worry about humidity unless you are getting condensate problems. Those readings sound ok to me.

With the windows open, and the house unheated, the humidity inside will tend to match that outside, so you really should not be surprised to get readings up into the 70s or even 80s in a damp UK summer.

You also mention walls skimmed and painted, that can add a lot of water to the house until it all dries completely, so again, no surprise if you have a temporary rise in household humidity.

Relax, it will drop in winter when the heating is back on.

Mine's reading 63% at the moment, on a damp muggy morning. In winter it can go down to half that.

Thanks for all your replies I really appreciate it, you have all confirmed what I thought. A well meaning friend got me worried, and I just wanted to check all was OK.
