Getting carcassing timber onto your Whitehaven site

Timber is delivered in packs or bundles on a flatbed; long lengths need clear access along the drop point. Whitehaven is inside our standard mainland delivery area.

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• On busy streets in Whitehaven, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

Sizing your order

A floor 6 m wide with joists spanning 3.6 m at 400 mm centres needs 16 joists, plus trimmers and noggins. The section and grade, such as 47 × 200 mm C24, come from span tables or your engineer; send us the timber schedule and we will price it.

Treated Carcassing Timber: choosing well

Cut ends

Treat any cut ends with a suitable end-grain preservative, especially on external work.

Which treatment?

Treatment is specified by use class. Timber inside a building is usually use class 1 or 2; external timber out of ground contact is use class 3; timber in ground contact needs use class 4.

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.

Treated Carcassing Timber questions

Why is my treated timber green or brown?

The colour comes from the preservative. It fades over time and does not tell you how well the timber is protected; the use class does.

What sizes of joist do I need?

That depends on the span, spacing, loading and grade. Use span tables or your engineer's design; building control will check.

Can you deliver carcassing timber to a site with restricted access in Whitehaven?

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 Whitehaven?

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.
