Treatment & Guarantee

This shed comes dip-treated as standard with a 1-year parts guarantee. It should be re-treated within 6 weeks of assembly and annually thereafter to maintain its appearance and protect against rot.

For enhanced protection, upgrade to pressure-treated timber, which extends the anti-rot guarantee to 15 years. As a bonus, you’ll receive a FREE upgrade to extra-thick 15mm cladding. Note that pressure-treated timber still requires water-proofing upon assembly and annually.

Georgian-style windows provide plenty of natural light to the interior. Both door and windows can be fitted in a variety of positions to suit your garden layout.
