Hi I hope somebody can help me with my problem.
I have a 3 bed semi mid 60's and suffer from very bad condensation in winter, mostly on the windows and pools of water on the sills, which are double glazed. I also suffer from mold on the curtains and in fitted wardrobes beside the window. The other 2 bedrooms suffer from condensation but not mold. I
I have had the gable wall cavity insulated a couple of years ago. We shower everyday and wet towels and robes hang on the doors to dry.
Have i got a damp problem? Ventilation issues, Cavity wall causing problems? Poor double glazing. What measures can i undertake to reduce the levels of condensation, I thought of a dehumidifier but i am concerned about the running cost and also think this is a sticking plaster and not the problem. Any advice would be gratefully received.
Almost certainly a problem of lack of ventilation. Your bathroom needs a good quality extractor with overrun timer and you need to use a de-humidifier to vastly reduce the damp levels. Open your windows on dry days even in the winter and if you can leave non-accessible ones on a night vent position.
How can i increase ventilation without having the windows open on cold nights - fit an extractor in the bathroom and kitchen.
Get wet clothes dry without generating more moisture into the house? - buy a tumble drier and vent to outside.
Is a dehumidifier worth the investment and do they cost a lot to run? Ones which reheat the air are costly to run, about the same as a 1kW fan heater.
