A plain-English local guide for Wye homes (TN25), written to help you diagnose the cause before you spend money.
Wye has medieval buildings that are often hidden behind later facades, so damp here can be a mix of old and new work. Start by finding out what your walls are made of and what has been done to them. Condensation in an owner-occupied home with a loft may suit a loft-mounted Dryzen system; leaks, damp from old repairs and rising damp need diagnosing first.
Wye sits at the foot of the North Downs, where the Great Stour passes through a gap in the escarpment, and the village postcode is TN25. Local heritage sources describe many buildings as medieval though often concealed by more modern facades, and Wye College's historic buildings date from 1447.
That has a practical meaning for anyone with damp. A Victorian-looking front can hide an older frame. Cement repairs on soft old brick can trap water. Extensions of different ages can meet at a cold junction.
Cement render, plastic paint and gypsum plaster on an old wall all hold moisture in. Taking those off is a builder's job and not a dehumidifier's.
Patches that follow rain mean water is getting in. Spots that follow cold mornings, in corners and on glass, mean condensation. A band low on the wall needs a specialist to look at it.
A Dryzen unit is mounted in the loft. In a medieval house with a steep roof and exposed timbers, that may not be practical.
Dryzen suits owner-occupied homes with a loft, because the unit is mounted there. It is not suitable for rental properties unless the landlord authorises the changes. If your home is in the Wye conservation area or is listed, check with the council before altering anything.
Start by measuring. A hygrometer in the coldest bedroom of an older Wye house tells you whether you are living above the 60 to 65 percent level at which mould and dust mites do well, before you decide what to change. For the full evidence, calculator and printable cheat sheet, see The Healthy Home Humidity Guide.
Parts of the village are. Check the extent with Ashford Borough Council before planning changes to the outside of a building.
Thick walls take a long time to warm and old houses often have little insulation. Surfaces stay cold, so moisture condenses on them.
Yes. The survey is free and includes a check that your loft is suitable.
Roughly 50 to 55 percent relative humidity is a sensible target, within the 40 to 60 percent band commonly suggested. Sustained readings above about 60 to 65 percent favour mould and dust mites. A dehumidifier does not kill mould, bed bugs or fleas, it helps stop the conditions they depend on. See our healthy humidity guide.
