Damp prevention tips.

Damp prevention tip sheet

We offer a comprehensive damp proofing service incorporating the latest materials and techniques available, but we are also here to offer advice and information. As a home owner it may be possible for you to reduce symptoms of damp related issues through regular maintenance and some considerations in your external landscaping and internal disciplines.

1.      Rainwater goods:

·         Ensure gutters and downpipes are of an adequate size and that they are installed correctly with the correct pitch to allow for drainage. Be aware of where they discharge.

·         Clean them regularly and ensure there are no leaks from joints.

2.      Drainage:

·         Look for indicators that drainage is blocked and deal with appropriately.

·         Clear grills of debris regularly.

·         Be aware of any issues in your local area in relation to drainage or water supply leaks.

·         Ensure hard areas such as adjoining patios have good natural drainage (look for green moss build up which can indicate an issue)

3.      External ground levels:

·         Don’t create issues of damp proof course bridging my locating raised beds, driveways and patios adjoining the building and exceeding internal floor levels.

·         Don’t place planters or log sheds against external walls.

·         Ensure that airbricks to sub floor voids are clear of obstructions and that paint has not sealed them.

4.      Roofing:

·         Check regularly for loose or missing tiles or slates.

·         Ensure that appropriate underfelt is present and that it is in good condition.

·         Ensure that your loft has adequate ventilation (insulation should not be taken to the ends of the rafters).

5.      Windows and doors:

·         Check that seals between frames and masonry are in good order.

·         Timber frames should be maintained to prevent decay from moisture ingress.

6.      Masonry:

·         Check pointing and ensure it is correct for the style of build (older properties may require a Lime mortar).

·         Look for tell tale signs of external dampness such as whitening of brickwork (efflorescence) green moss build up, stains and water runs.

7.      Internal disciplines:

·         Adequate and functioning extraction may be required in wet rooms such as bathrooms and kitchens. Where they are manually operated check that occupants all know how and when to use.

·         Ventilation is essential but should not be at the expense of internal temperatures particularly in colder periods. Open windows to allow a movement of air through the property, experiment with                          combinations (try an upstairs window to the rear and a ground floor front window).

·         Allow for appropriate heating, maintaining a constant ambient temperature may be more cost effective than heating that comes on later at a higher temperature.

·         Internal decoration should be appropriate for the style and age of build, older properties with lime plaster may need specialist paints.
