At Subsidence Company, we deliver end-to-end structural movement assessment and repair services for residential and commercial properties. Our work centres on identifying the causes of ground-related movement and implementing robust, compliant remedies that protect buildings over the long term.

By integrating detailed surveys, advanced diagnostics, and proven repair strategies, we support property owners and stakeholders from first assessment through to certified completion.

How Does a Subsidence Company Support Properties Affected by Ground Movement?

A subsidence company provides a coordinated service covering investigation, diagnosis, remediation, and verification of stability.

This includes initial site inspections, soil and drainage analysis, crack and movement monitoring, and geotechnical input. Once findings are confirmed, tailored repair measures are implemented, followed by post-repair checks and reporting to demonstrate that movement has been resolved.

What Cost Should Be Expected for Subsidence Repairs?

The cost for subsidence repairs ranges from £1,000 to over £50,000, depending on the severity of movement, property size, access limitations, and the type of repair required.

Budgets are primarily influenced by the underlying cause of the subsidence, the extent of investigations and monitoring, the chosen repair method, regulatory and approval processes, and any associated works such as drainage improvements or vegetation management.

Which Factors Most Commonly Trigger Subsidence in Buildings?

Subsidence is frequently linked to a combination of environmental and construction-related influences, including:

• Shrink–swell clay soils – Ground expansion and contraction caused by changes in moisture levels.
• Vegetation and tree roots – Moisture extraction close to foundations leading to soil shrinkage.
• Defective drainage systems – Loss of supporting ground due to leaking pipes or collapsed drains.
• Inadequate ground compaction – Often associated with extensions or historic alterations.
• Surrounding development or historic activity – Ground disturbance from nearby works or former land use.

What Investigation Techniques Does a Subsidence Company Use?

A subsidence company follows a staged investigation process beginning with a visual assessment of cracking, distortion, and settlement.

This may be supported by crack monitoring, trial pits, borehole investigations, CCTV drain surveys, and laboratory soil testing. Where movement is unclear or ongoing, monitoring equipment may be installed to collect data over time before confirming the diagnosis.

Are Structural Surveys and Monitoring Part of Subsidence Services?

Subsidence specialists routinely provide comprehensive structural surveys and ongoing monitoring programmes.

These services are delivered by qualified engineers or surveyors and are particularly valuable where movement is active but not yet severe. Monitoring data supports insurance decisions, repair design, and confirmation of long-term stability following remediation.

Which Repair Options Are Commonly Used by a Subsidence Company?

Repair strategies used by a subsidence company depend on cause, severity, and ground conditions, and may include:

• Traditional underpinning – Reinforcing shallow foundations with mass concrete.
• Mini-piling or helical piling – Transferring loads to deeper, competent strata.
• Resin injection systems – Stabilising loose ground and filling voids beneath foundations.
• Drainage renewal works – Eliminating soil erosion caused by leaks or failures.
• Vegetation management measures – Installing root barriers or removing problematic trees.

What Timeframe Is Typical for Subsidence Investigation and Repair?

Subsidence projects can extend over several months depending on monitoring requirements and repair complexity.

Monitoring phases may last 6 to 12 months before repairs are authorised. Once approved, structural repair works such as underpinning or piling typically take 2 to 6 weeks, with internal finishing works following where needed.

What Compliance and Permissions Apply to Subsidence Repairs?

Subsidence repairs are governed by Building Regulations, particularly where foundations are modified or strengthened.

Building control approval and staged inspections are commonly required. Additional consents may apply for listed buildings or conservation areas, with compliance documentation managed as part of the service.
