Specialists in water mains repairs, water pipe repairs and replacements, Mains, Moles and Holes use specialist technology called impact moling which reduces time, cost and disruption to your property. Instead of digging a continuous trench, two smaller pits allow access to your water pipes for repairs or replacement. We cover the Thames Water, Sutton and East Surrey Water, Southern Water, Veolia Water, and South East Water areas. If your property was built prior to the 1970s, you may have a lead water pipe supply, which can mean that lead is present in your water supply. Replacement water pipes can also provide a better flow rate, which is essential for some modern plumbing.
