What customers say

Based on genuine customer reviews

Promptness and clear communication emerge as the qualities that customers of this Portsmouth drainage and groundwork specialist mention most often. Dave and his team are repeatedly described as arriving when they say they will, diagnosing problems quickly and explaining each step so that householders understand what they are paying for. Several reviewers note that drains were unblocked and the affected area disinfected, with one awkward job involving a sunken driveway traced to an old disused cesspit, requiring excavation close to a foul drain and careful backfilling.

The team is praised for working tidily and for completing what was agreed, even where the task proved difficult or fell outside ordinary hours. Customers also highlight the fairness of the pricing, describing quotes as reasonable and noting that no inflated charge was applied for a call-out at a difficult time of year. Politeness, patience and a friendly manner come up frequently, alongside appreciation for advice given over the phone when an immediate visit was not possible. The consistent theme is a professional, experienced service that resolves drainage problems efficiently and treats people decently throughout, leaving the work area clean and the householder fully informed.

My parents drive was sinking and crumbling in places. Dave and his team sorted out this awkward issue with a short excavation , diagnosis and quote for repair. It turned out to be an old disused cesspit . Significant excavation back fill and care required as it was very close to foul drain. This was completed with legalities being highlighted where appropriate. Awkward job, completed as agreed with thoroughness. Very experienced and dead straight, highly recommended.
