By Society for the Protection of Ancient Buildings (SPAB)
On founding the SPAB in 1877, William Morris spoke of the need ‘to stave off decay by daily care, to prop a perilous wall or mend a leaky roof’. SPAB's aim is to build on the success of previous years' National Maintenance Weeks and to highlight the importance of regular health checks for buildings, whatever their age. As with our own health, prevention is better than cure. Neglect of routine building maintenance results in the need for costly and disruptive remedial work. For example, failure to clear a gutter can cause a blockage, which may lead to damp and damage in a building. This guide provides a quick checklist to help you protect your building and to establish when advice and assistance is needed.
The following general points are worth bearing in mind:
Roof
Checks you can make:
Monthly - slipped slates and tiles
6 Monthly - roofspace during heavy rain Annually - abutments - moss growth - pointing - parapets
Gutters and Rainwater Pipes
Do not forget to monitor underground drainage. Gulleys beneath rainwater pipes should be cleaned out by hand (with gloves) and drains should be rodded out if they overflow during wet weather.
Checks you can make:
Monthly - check for any obvious leaks or blockage
6 Monthly - inspect gutters and downpipes in heavy rain Annually -clean gutters, downpipes, (and drains if showing signs of blockage).
Walls
6 Monthly - clear air bricks Annually - inspect pointing - check ground level at wall bases
External Joinery
Checks you can make:
Annually - Inspect paintwork
Roof Space
Checks you can make:
6 Monthly - Inspect roofspace for leaks and signs of decay
Services
Chimney Flues
Chimneys should be regularly swept, and lined where a heating appliance requires it.
Checks you can make: Monthly - check smoke alarm batteries 6 Monthly - vacuum dust from smoke alarms Annually - check pipe lagging (before winter) - have gas appliances serviced - sweep chimneys 5-10 yearly - have wiring checked professionally
Movement
Subsidence can occur in clay areas with large trees in close proximity to buildings. Diagonal cracks greater than 5mm wide require monthly monitoring to establish whether they are increasing in length and width, indicating that there is on-going structural movement. If a crack appears minor, repointing with an appropriate mortar will prevent moisture entering. If the crack opens further after pointing, the advice of a chartered structural engineer should be sought.
Checks you can make:
Annually - look for any new cracks
Timber Defects
Check annually for signs of rot (for instance, under stairs and in cupboards). Dampness and poor ventilation promote fungal and insect attack. It is important to address the underlying cause and not to rely solely on chemical timber treatment. Beware that some companies recommend the removal of more affected timber than is really necessary.
Checks you can make: Annually - inspect timber for new decay
Dampness
As with rot, always aim to treat the cause rather than symptoms. Be aware that damp-proof courses, water-repellent solutions and plastic-type wall coatings do more harm than good when inappropriately applied to buildings. Where assistance is required, consult a chartered surveyor for independent advice rather than a remedial company with a vested interest in their own recommendations.
Checks you can make:
6 Monthly - look for signs of dampness
Garden vegetation Plants often enhance buildings, but consider control or removal of trees or climbers if there is evidence that they are damaging walls or blocking gutters. Ivy can force joints open and also damage the cores of solid masonry walls. If ivy is to be removed it should usually be cut just above ground level and, once dead, removed.
Checks you can make:
Annually - check plant growth on and near walls
Safety
Consider creating a log book to record maintenance repairs or alteration. This should help you, your professionals and future owners.
In some cases maintenance work may require permission, including listed building consent if the structure is listed. Current legislation also prevents disturbance of certain types of flora and fauna, including bats.
