Things to check before you order

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; building control will tell you what applies.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Planning the drop in Chelsea

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

• Give us the full postcode for the drop point; deliveries around SW10 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.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

A quick quantity check

An extension in Chelsea with 12 m of cavity wall needs DPC in both leaves: about 1 roll in 30 m lengths once laps are allowed for. A 50 m² floor slab needs about 57.5 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Common questions from Chelsea

Do you supply cavity trays?

Yes, with stop ends and weep vents for openings and abutments.

Where does the DPC go?

Usually at least 150 mm above outside ground level, linked to the floor DPM.

How soon can damp proofing be delivered in Chelsea?

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.

Can I add other materials to my Chelsea delivery?

Yes. Put everything on one list, from damp proofing to fixings and PPE, and we will price it as one delivery where the products can travel together.
