Yes. Sevenoaks itself along with the surrounding villages such as Riverhead, Dunton Green, Otford, Kemsing and Seal are all within our normal working area across TN13, TN14 and TN15.

Cutting the roots back with high-pressure water jetting restores flow, but it does not deal with the reason they got in, which is almost always a crack or an open joint. The lasting fix is to seal that defect, usually with a resin patch repair or a liner. If someone offers to jet the same run every year without ever mentioning the defect, you are buying maintenance rather than a repair.

Because properties here often have long private runs crossing large plots. Without a camera you are guessing where the defect is, and on a long run under a lawn, a drive or mature planting, guessing is expensive. A survey identifies the position of the defect so the repair is targeted.

Often, yes. Where the pipe still holds its line and shape, cracks and open joints can be repaired from an existing inspection chamber using a resin patch or a liner, with no excavation at all. Where a section has fully collapsed or lost alignment, excavation is the honest answer and we will say so.

Yes, and on a large period property with extensive private drainage it is often money well spent. A standard building survey does not inspect underground drainage, so the condition of a long private run is otherwise unknown until something goes wrong.

Longer than a standard domestic survey. Where there are several runs, multiple chambers and a long distance to the sewer connection, it can take most of a morning. We will give you a realistic time and price when we quote rather than on the day.

Drainage serving only your property, inside your boundary, is normally yours. Shared drains and lateral drains beyond the boundary generally transferred to the water and sewerage company in 2011. On a large plot the boundary point is not always obvious, and a survey establishes it.
