How delivery works in Renfrew

Rolls are light enough to travel with a mixed load and are handed off at the kerb. Renfrew is inside our standard mainland delivery area.

• If neighbours share the access, it helps to let them know a lorry is coming.
• Give us the full postcode for the drop point; deliveries around PA4 are priced to the exact address.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Working out quantities for your Renfrew job

An extension in Renfrew with 32 m of cavity wall needs DPC in both leaves: about 3 rolls in 30 m lengths once laps are allowed for. A 25 m² floor slab needs about 28.7 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Getting the right damp proofing

Laps and joints

DPM and DPC need generous laps and sealed joints; follow the manufacturer's guidance.

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.

How thick should a DPM be?

How soon can damp proofing be delivered in Renfrew?

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.

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.
