• Give us the full postcode for the drop point; deliveries around PA5 are priced to the exact address.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• In summer Johnstone gets around 17h 35m of daylight, but early deliveries still beat the traffic and give the longest working day.

Choosing damp proofing

DPC width

Match the DPC width to the wall leaf so it runs the full width of the masonry.

Is radon protection needed?

Parts of the UK need radon protection in new buildings and extensions. UKHSA radon maps show the areas; the council's building standards service will tell you what applies.

In Scotland most building work needs a building warrant from the local authority, assessed against the Building Standards Technical Handbooks.

Questions about damp proofing delivery in Johnstone

How soon can damp proofing be delivered in Johnstone?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

What is the difference between DPC and DPM?

DPC is a strip built into walls to stop damp rising through the masonry. DPM is a sheet laid under a concrete floor slab. They are lapped together so there is no gap.

Is there a minimum order for delivery to Johnstone?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

Do I need a radon barrier?

It depends on where you are. In radon-affected areas building standards require radon protection in new buildings and extensions.
