Our guide to preventing and treating damp

Damp problems are usually most apparent during the winter months, but you can look for warning signs at any time of year. There are many causes for damp in your home, these are the four main issues;

  • Insufficient Ventilation

  • Penetrating Damp

  • Leaking Plumbing

  • Rising Damp

How To Prevent Damp and Mould

  1. Keep on top of outdoor home maintenance

Prevention is better than cure when it comes to damp problems. Check your roof regularly for damage, especially after winter storms. Keep gutters clear and fix or replace especially after winter storms.

Keep gutters clear and fix or replace as soon as any damage occurs. Inspect the pointing of exterior brickwork, and if you have any concerns about crumbling mortar speak to a professional to investigate repairs.

  1. Keep your home warm

Condensation occurs when warm, moist air touches a cold surface like a chilly window pane or a cold external wall. Loft and wall insulation can help create warmer spaces, and properly fitted double glazing will avoid misty windows as the inner panel of glass is insulated against the cold air outdoors.

  1. Ensure your home is well-ventilated

Providing a route for moisture to escape from your home will help to minimise condensation. Double-check that washing machines and tumble dryers are plumbed in and vented correctly. Install an extractor fan in bathrooms and kitchens if one isn’t already in place.

  1. Avoid producing lots of moisture.

Drying washing indoors can create a lot of condensation, so dry laundry outdoors on a rotary dryer or use a tumble dryer whenever possible.

  1. Take care when cooking

Pans on the stove, as well as kettles can produce considerable amounts of steam and moisture. Covering pans with a lid whilst cooking will help minimise condensation on your kitchen windows.

  1. Choose moisture resistant décor finishes

If your home is prone to damp or condensation, choose wall finished that make problem prevention easier. Opt for painted surfaces and choose paints designed for use in kitchens and bathrooms.

How to Repair Damage Caused By Damp

  1. Damp stains or mould on painted walls and ceilings

Once the source of the damp has been fixed, allow the area to thoroughly dry out using a dehumidifier if needed. Then, treat the surface with a mould removing treatment following the instructions on the packaging carefully. Once the surface is free of mould and dry, it can be painted with a damp seal or stain blocker paint which will ensure that the staining does not bleed through the emulsion once completed.

  1. Mouldy grout and sealant in the bathroom or around sinks

If the grout and sealant is in good condition, begin with a mould removing treatment. Following the instructions on the packaging, remove as much of the mould as possible.

This may be enough to revive the area. However, if it doesn’t fully remove mould stains from silicon sealant, allow the area to dry thoroughly and then cut the old sealant away with knife blade. Using a mould-resistant sealant and sealant gun, re-seal the affected area and wait until the sealant has cured before allowing the area to get wet.
