Trees near buildings

Most trees growing near buildings cause no damage. But in some cases, subsidence and structural damage can be linked to tree roots. Blocked drains and lifted paving may also be a problem. Understanding the factors involved in tree damage to buildings, including soil type and depth of foundations, will help both tree and house owners determine what action to take and when to get professional help.
