How delivery works in Harrow
Sheets come in packs on the lorry bed, crane-lifted or hand-offloaded. Harrow is inside our standard mainland delivery area.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
- On busy streets in Harrow, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
- Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
OSB, MDF & Chipboard: choosing well
OSB or plywood?
OSB3 is usually cheaper and fine for most structural decking in humid conditions. Plywood is stiffer, takes fixings near edges better and performs better where it may get wet.
Which flooring?
P5 chipboard flooring is the standard moisture-resistant floor deck. 18 mm is common at 400 mm joist centres and 22 mm at 600 mm centres, but follow the maker's span table.
OSB, MDF & Chipboard questions
Can OSB get wet?
OSB3 copes with humid conditions and short exposure during construction, but it should not be left in the rain for long or used where it stays wet.
Can I add other materials to my Harrow delivery?
Yes. Put everything on one list, from OSB, MDF and chipboard to fixings and PPE, and we will price it as one delivery where the products can travel together.
What chipboard flooring should I use?
P5 moisture-resistant tongue-and-groove chipboard. 18 mm is common on joists at 400 mm centres and 22 mm at 600 mm centres.
Can you deliver OSB, MDF and chipboard to a site with restricted access in Harrow?
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.
