Alnwick postcrete supply — sets in 5 minutes, fence up in 30
Postcrete bag is what most Alnwick fencers reach for first. Postcrete is a rapid-set concrete sold in 20kg bags. Pour around the post in a hole part-filled with water, give it a stir with a stick, walk away — sets stiff in 5–10 minutes, full strength inside an hour. Saves a day vs traditional wet mix. We deliver across Alnwick and the north Northumberland coast and the wider Northumberland footprint — 1–2 day.
Whether you're laying a single back-garden run on a Warkworth or Amble property or quoting a multi-house developer plot, the timber's the same: pressure-treated softwood, sized properly, dropped where you need it.

What Alnwick looks like for fencing
Heavy coastal weather on anything east of the A1 — Bamburgh, Seahouses, Embleton, Warkworth all see salt air and serious wind. We always recommend top-spec for these: 4×4 pressure-treated posts, gravel boards, cap rails, galvanised fixings. Inland (Rothbury, Lemmington) is sheltered and standard spec is fine. Long drives mean stock-and-deliver runs are more cost-effective than multiple trips.
Neighbourhoods we drop to: Warkworth, Amble, Rothbury, Felton, Lesbury, Bamburgh, Seahouses, Lemmington, Embleton. Plus surrounding postcodes (NE65–NE68) — drop your postcode at checkout if you're unsure.
