Having your chimney flue checked is vital. As well as the installation of new chimney linings we also carry out chimney lining repairs too. Appliances that use gas, oil wood or smokeless fuels all produce Carbon Monoxide, which can be fatal. Even low levels of the poison can cause lasting damage to your health. Sometimes there are obvious signs that a chimney repair is required such as excessive soot, falling debris, fumes, problems with the quality of the fire and overheating chimney walls. The inside of the chimney (with age and use) becomes corroded and then there is a risk of carbon monoxide leaking into your home. Whether you need a repair to the chimney lining, a chimney survey, a flue repair, chimney liner for an open fire chimney or a flue liner for a wood burning stove! Whatever your needs we can provide the solution at a competitive price.
