If the walls of your property are damp to the touch or you’ve spotted spores or fungal seeds dotted around your home, it’s best to call in timber preservation experts as quickly as possible. Dampness can cause untold damage, have negative effects on your health and compromise the structural integrity of your home. The most common types of dampness are wet rot and dry rot.


Wet rot is generally signified by dampness in the walls which can usually be detected by an initial visual survey. A more in-depth survey can be undertaken which involves lifting carpets to check sub floors and joists; this survey does incur a fee. If there are signs of wet rot on the joists themselves we may need to replace joist ends or full joists. You will be kept updated of our progress at all times and we will always advise if any additional work is required before proceeding.


Dry rot is a more invasive problem. Timber decays when certain fungi is present and needs to be treated as soon as possible; if all fungus isn’t removed it can come back quite quickly, travelling into masonry and timbers by working its way through mortar. Dry rot can easily spread throughout the entire house, from the floor to the roof, resulting in costly repairs if not dealt with soon enough.

When treating dry rot, K & L Damp Proofing will remove all plaster from the walls affected in order to expose all timber in contact with the rot. We will treat the walls up to a metre past the dry rot, removing infected debris and irrigating the walls. Once treated, we will sterilise with fungicide spray before replacing timber with treated timber and re-plastering using renovation plaster.

All timber preservation work is given a 10 year guarantee as standard, or you can opt for a guarantee of up to 30 years which is underwritten by the relevant insurance company for your peace of mind.
