Hello everyone,

About 2 years ago I bought a house built in ’64. We have mostly completely renovated the house ourselves.

One problem is still the damp basement.
As it looks, the basement continuously draws some moisture through the walls. However, this is within a manageable range.
The basement has received new and tight windows (the old ones were leaky and partly already broken).

We use the basement as a storage room for all sorts of things, also children’s clothes, fabrics, etc.
The basement has a laundry room where there is also a dryer with a condensate water container. I don’t know if a lot of moisture is released to the surroundings from this. Maybe someone can tell me? Most of the moisture of course ends up in the condensate water container, but since it sucks in the surrounding air and then releases it again, I fear it also gives off a certain amount to the environment. It runs about 5 times a week.

So, now to the actual topic: how do I deal with the moisture in the basement?
I have placed humidity meters in several rooms and want to keep the humidity under or at a maximum of 60 to 65%.

My approach:
In winter: Open all windows one to two times a week overnight. That is completely sufficient. It’s done quickly. Thus, I keep the humidity in winter between 50 and 65%.
In autumn and spring: Depending on the outside temperature, open the windows about 4 to 7 times a week overnight. This involves quite a bit of effort but still works.
In summer: Yes, it gets more problematic here. The outside temperature is higher than the basement temperature. That means if I open the windows, I rather draw moisture into the basement. So I put two dehumidifiers in the basement that keep the humidity at 60%. They then extract up to about 2-3 liters of water from the air daily.
Unfortunately, this costs about €200 in electricity per summer.
Does anyone perhaps have a better suggestion for this?

Renovation is out of the question for me. I had a company come by that talked about horizontal barriers, etc. that would have easily cost between €15,000 and €30,000.

Digging up myself, sealing and insulating from outside will also cost me about €8,000 upwards and the problem is that I can’t get to one side because there is a paved road running directly along the house there.

I am grateful for good suggestions, maybe someone knows something else ;)

Best regards
Specki
