How to prevent and stop mould and dampness.

Hi. sounds like a ventilation problem you need to fit vents/grills to any cupboards that are closed in, also some ventilation to outside air would be beneficial although a bit cold in winter . Think about upvc windows long term with built in trickle vents or even timber but higher maintenance. Hope this helps. Emmpire construction ltd

There are specific ventilating units on the market in your case I would recommend the insertion of a positive input ventilation system (Flat master)or similar I have come across this problem many times and fitted these systems they do work Hope that helps

Mould on fabrics and books is caused by excessively high humidity. If these items are in an area of restricted air movement then they will suffer more than if open to the room. As temperatures drop at night, the relative humidity necessarily rises providing the levels required to sustain mould growth. The subsequent lack of air movement and slower return to room temperature of the trapped air extends the period supporting mould growth, allowing it to take hold. These phenomena typically also explain the problem of mould being more evident in room corners. Insulating walls can have its place in certain scenarios and is a good thing in general. However, like improving the u-values (thermal conductivity) of the windows, it is not addressing the core issue that there is simply too much moisture in the room. Indeed, I have seen wall insulation simply move the problem to another part of the property. Providing ventilation for cupboards can be good advice, though this again misses the root cause. Effective control of the humidity levels should overcome all the above without recourse to cutting holes in cupboards, changing windows or additional wall insulation. This is not to dissuade you from upgrading windows or wall insulation, though do be aware, mould should not be your primary reason for doing them. Positive Input Ventilation is usually the best ventilation type for the problems described, but placement of any unit is critical as is choosing the best unit for the job. Even if correctly installed, I have still replaced many lower end PIV units for more long-lived and occupier-friendly equivalents. Given that a fair chunk of the cost of an installation is often the installation, skimping on the unit is generally a false economy. Animals are an important source of moisture, just as we are, simply through breathing. If they are larger animals, and if they spend most of their time indoors, then this additional effect could be significant.

Mould is coming from dampness that is hitting cold surfaces ie: cold Walls and window areas. Bedrooms are the worst for this as you breath out a lot of water vapours while asleep, even more if 2 people in the room. The outside Walls will need insulating, either with an insulating plasterboard or battens fixed with insulation between. This will keep the surface of the Walls and the room itself warmer in winter and cooler in summer. A new energy efficient window would also help a lot. It is basically cold bridging through from outside. Hope this helps, shaun

Ventilation is the answer. The mould will be growing on moisture which is trapped inside the property. The moisture will be created from things such as bathing, cooking, cleaning, washing, drying, breathing etc. As homes are made more energy efficient with insulation and double glazing, the moisture inside the property is unable to escape, and will form as condensation on walls and windows. Ask a ventilation consultant to come around to your property to recommend the correct solution to your problem. Kind Regards
