What Affects the Cost?

Lerwick's coastal location, high rainfall, salt-laden winds, and historic stone construction drive demand for specialist damp treatment. Pricing depends on damp type (rising, penetrating, or condensation), building age and material, wall thickness, area requiring treatment, site access difficulties, weather windows for external work, and material costs reflecting remote supply chains. Properties with cavity walls, solid stone construction, or severe salt damage typically cost more. Specialist chemical treatments are more expensive but often essential in Shetland's harsh climate.

Money-Saving Tips

Obtain multiple specialist surveys to confirm diagnosis—misidentifying damp type wastes money. Bundle related work (roof repairs, external pointing) to minimise site mobilisation costs. Consider phased treatments: address the worst areas first, then tackle secondary issues later. Regular ventilation and maintenance prevent recurrence, reducing long-term expenses.

Frequently Asked Questions

Why are damp proofing costs higher in Lerwick than mainland Scotland?

Lerwick's exposed coastal location, year-round moisture, salt spray, and remote geography increase both labour and material costs. Specialist contractors must account for difficult weather windows, limited supply chains, and properties built with traditional stone construction requiring specialist techniques. Travelling costs for specialists are also higher.

How long does damp treatment take and can I stay in my home?

Rising damp injection typically takes 3–5 days for a standard property but cures over 4–8 weeks. Penetrating damp work depends on wall size and weather. Most treatments allow occupancy during work, though some chemical treatments require ventilation. Discuss specifics with your chosen specialist; coastal weather may extend timescales.

What's the difference between rising damp and penetrating damp?

Rising damp travels upwards from the ground through porous materials, usually below 1.5 metres; it requires chemical DPC or injection treatment. Penetrating damp enters horizontally or downwards through cracks, poor pointing, or weather exposure; it needs external sealing and waterproofing. A specialist survey identifies which you have.

Are damp proofing treatments guaranteed in Shetland's climate?

Reputable specialists typically guarantee work for 10–20 years, though extreme coastal exposure can limit longevity. Chemical DPC usually carries manufacturer guarantees. Condensation control relies on ongoing ventilation and property use; guarantee terms vary. Always get guarantees in writing and discuss climate-specific limitations with your contractor.
