If it is subsidence, diagnosing the problem early can save you a lot of anxiety and money.<\/p>\n<p>It\u00e2\u20ac\u2122s important to remember that <strong>subsidence can usually be rectified<\/strong>. Check whether your buildings insurance covers subsidence. Most insurers will aim to be as helpful as possible in dealing with any claim. They will recommend specialist advice. A Chartered Surveyor\u00c2\u00a0will be able to work out whether or not there is subsidence and establish the likely cause.<\/p>\n<p><span style=\"color: #3366ff;\"><strong>What is subsidence and how is it caused?<\/strong><\/span><\/p>\n<p>Subsidence usually happens when:<\/p>\n<p><strong>Houses are built on clay soils<\/strong> and either the water table drops due to a long, dry spell or water is sucked out of the soil by trees and bushes. As the clay contracts it pulls the foundations, triggering deflection which may cause structural damage to buildings. Different types of clay shrink and swell at different rates.<\/p>\n<p><strong>Water leaks into the soil<\/strong> from a broken drainpipe, for example, and washes soil away from the foundations. This type of subsidence usually happens to soils with a high sand or gravel content, and sometimes in chalk.<\/p>\n<p><strong>Previous mining activity<\/strong> has taken place.<\/p>\n<p><span style=\"color: #3366ff;\"><strong>How long will it take to rectify? <\/strong><\/span><\/p>\n<p>Establishing whether or not there is a problem can take a long time. There is rarely any cause for real concern unless cracks appear suddenly and are more than 3mm wide (the width of a 10 pence coin). In most cases the first sign of a problem is\u00c2\u00a0visible cracks in a particular area of the house and these may need to be measured and monitored, perhaps for as long as twelve months. Solving subsidence can be a lengthy process which can take up to two years.<\/p>\n<p><span style=\"color: #3366ff;\"><strong>What can be done to fix it?<\/strong><\/span><\/p>\n<p><strong>Underpinning <\/strong>the foundations usually prevents further movement. It\u00e2\u20ac\u2122s a lengthy, costly and disruptive procedure that can cost anywhere between \u00c2\u00a35,000 and \u00c2\u00a350,000 or more.\u00c2\u00a0It is estimated that fewer than 10 per cent of properties suffering from subsidence need underpinning and the Institution of Structural Engineers recommends it is only used as a last resort.<\/p>\n<p><strong>Tree roots <\/strong>Consumer organisation <em>Which?<\/em> estimates that about 70 per cent of all subsidence cases are due to <strong>tree roots sucking moisture out of the soil<\/strong>. Where this is the case, trees may be removed. It may be a quick and easy way to solve the problem. Be aware that\u00c2\u00a0<strong>removing a tree may add to the\u00c2\u00a0problem<\/strong>,\u00c2\u00a0but this is usually very rare. A Chartered Surveyor will be able to put you in touch with someone who can advise you on whether or not a tree should be removed or simply pruned to reduce the amount of moisture it takes out of the soil.<\/p>\n<p><strong>Pipework <\/strong>Where the soil beneath the property is being washed away because of leaking drains or water mains, a less intrusive remedy might be possible. In most cases, repairs to leaky pipework will be enough to stabilise the property without underpinning.<\/p>\n<p><strong>\u00c2\u00a0<\/strong><span style=\"color: #3366ff;\"><strong>Who pays? <\/strong><\/span><\/p>\n<p>Check whether your insurance policy will cover the cost of investigation and repair. If the insurance company considers this reasonable, you will get your costs back. A policy excess will probably be specified in your insurance documents, in which case you will need to pay up to that amount before any further\u00c2\u00a0costs are covered by insurance.<\/p>\n<p>Your Chartered Surveyor will liaise with your insurance company and guide you through any claim you need to make. They can also help design and arrange for any work needed to fix the problem.<\/p>\n<p><span style=\"color: #3366ff;\"><strong>Where to go for advice?<\/strong><\/span><\/p>\n<p>If you\u00e2\u20ac\u2122d like to know more about subsidence or how one of our RICS regulated surveyors can help you, contact us on <a href=\"http:\/\/www.propertysurveying.co.uk\/INDEX\/INDEX1.html\">www.PropertySurveying.co.uk<\/a><\/p>\n<p>&nbsp;<\/p>\n<p><em>As the world\u00e2\u20ac\u2122s largest professional body for chartered surveyors, RICS (Royal Institution of Chartered Surveyors) offers clear, impartial expert advice on these issues.\u00c2\u00a0 Chartered Surveyors cover all aspects of property, from conserving and restoring historic, residential, commercial, industrial and retail buildings to planning home extensions, home buyer surveys and valuations, dilapidations, boundary disputes, energy efficiency and party walls advice.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you spot any of the problems listed below, and cannot find a reason for them, get specialist help as soon as possible.
