Despite central heating, loft insulation and replacement double-glazed windows, the rooms upstairs get cold even when the heating is on, and there is a musty smell in the bedrooms.
If you find your home suffering from condensation and that horrible musty smell it’s quite apparent that you most likely have a damp problem and no number of air freshener’s are going to solve that,
The best solution to this problem would be to call Apex Damp and Wall Ties for more information or advice contact Apex on 0800 634 9899
