Things to check before you order

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.

Laps and joints

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

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.

How much will you need?

An extension in Barnstaple with 16 m of cavity wall needs DPC in both leaves: about 2 rolls in 30 m lengths once laps are allowed for. A 20 m² floor slab needs about 23 m² of DPM including laps, which is 1 roll of 4 × 25 m sheeting.

Planning the drop in Barnstaple

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

• With roughly 7h 54m of daylight in Barnstaple around the shortest day, morning deliveries leave more working light for the job.
• In summer Barnstaple gets around 16h 34m of daylight, but early deliveries still beat the traffic and give the longest working day.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

Common questions from Barnstaple

Can I add other materials to my Barnstaple 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.

Do I need a radon barrier?

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

How soon can damp proofing be delivered in Barnstaple?

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.
