How delivery works in Romford

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

• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Picking the right product

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; 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.

Ordering damp proofing for Romford: FAQs

Where does the DPC go?

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

Can you deliver damp proofing to a site with restricted access in Romford?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

Is there a minimum order for delivery to Romford?

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.

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.
