Up to 50 m²
From £750A minimum project allowance covering specialist equipment, mobilisation and a planned treatment pattern.
Clear guide pricing
Start with the
size of the garden.
Every site needs an assessment, but a sensible guide helps you decide whether specialist treatment is the right next step.
01 / Guide range
A useful estimate.
A site-specific quote.
We use the treatment area as the starting point, then consider access, compaction depth, probe spacing and the amount of calcium sulphate required.
50–100 m²
£12–£18 / m²Approximately £1.11–£1.67 per ft². A 75 m² treatment area would typically guide at £900–£1,350.
Over 100 m²
Quoted to siteLarger gardens and multi-plot work may benefit from a lower rate per square metre where access and conditions are consistent.
Guide prices, not an online quotation. Figures are provisional estimates for suitable domestic sites. Your written quotation will confirm the treatment area, scope, price and applicable VAT position before any work is agreed.

- High-pressure air treatment at planned probe points
- Calcium sulphate delivery within the treated zone
- Low-disruption working and clear aftercare guidance

03 / What shapes the quote
The square metres
are only the beginning.
Access
Side-gate width, steps, slopes and the distance between the vehicle and treatment area.
Ground conditions
The depth and severity of compaction, clay mineralogy, existing drainage and where water can move.
Treatment pattern
Probe spacing and injection depth are planned around the affected area rather than applied as a generic surface treatment.
Site scale
One garden, several plots or a development-wide programme all carry different mobilisation efficiencies.
04 / Putting it in context
More than lawn aeration.
Less disruption than excavation.
Conventional hollow-tine lawn aeration is a shallow maintenance service and is priced accordingly. Excavated drainage can involve trenches, pipework, imported aggregate and reinstatement. Hydrofence sits between them: specialist treatment at depth, delivered without defaulting to digging up the whole garden.

Specialist deep treatment with air and mineral amendment
Excavated drainage
Drain runs, spoil, materials and reinstatement

the water sits.
Send the address, approximate treatment area and a few photographs after rain. We can then discuss whether an on-site assessment is worthwhile.
