Waldenhaus warranty · v1.3

Published in full, before you order.

Most greenhouse warranties end the moment the weather gets interesting. "Extreme weather conditions excluded" is industry standard. Ours is published here, on this page, before you spend a penny.

01 · COVER

Two product families.
Two warranties.

Each greenhouse is covered against the failure mode that actually matters for its material: rot for timber, corrosion for steel. We list what's covered and what isn't in plain English, on this page, before you order.

NORDIC

Timber greenhouses

10-year anti-rot frame warranty (conditional on re-treating timber with any UK-purchased wood preservative every 2 years) + 2-year polycarbonate panel warranty (manufacturer defects).
✓What's covered
  • Rot in the load-bearing pine frame attributable to material defect
  • Structural failure caused by frame rot during the warranty period
  • Polycarbonate delamination of the cellular structure
  • Polycarbonate light-transmission loss beyond industry specification
  • Polycarbonate edge cracks originating from a production fault
✕What's not covered
  • Surface weathering of the timber (silvering, greying, tannin bleed, knot movement, seasonal shrinkage). Slow-grown European pine weathers like this by nature, so it falls outside defect cover
  • Rot resulting from failure to re-treat every 2 years (see conditions)
  • Damage from wind speeds > 50 mph sustained or any Met Office Named Storm event
  • Impact damage (hailstones, falling branches, gravel, projectiles)
  • Damage from incorrect assembly or modifications

Conditions of cover

Anchoring: on a prepared level base, anchored with the supplied Heavy-duty Ground Anchors per installation guide. Failure to anchor voids the structural warranty.

Maintenance: re-treat with any UK-purchased exterior wood preservative every 2 years. Keep a brief dated record; a photo of the freshly-treated frame is best.

SteelRoot

Galvanised-steel greenhouses

2-year manufacturing defect warranty on cellular polycarbonate panels + 10-year anti-corrosion warranty on the galvanised steel frame.
✓What's covered
  • Through-corrosion of the zinc coating on the steel arch frame
  • Manufacturing defects in the galvanisation process
  • Polycarbonate light-transmission loss greater than 6%
  • Polycarbonate delamination of the cellular structure
  • Polycarbonate edge cracks from a production fault
✕What's not covered
  • Surface marking from screw heads and minor finish abrasion at fastener points. This is inherent to galvanised steel and falls outside defect cover
  • Corrosion from un-treated mechanical damage caused after delivery
  • Damage from wind speeds > 50 mph sustained or any Met Office Named Storm event
  • Impact damage (hailstones, falling branches, gravel, projectiles)
  • Damage from incorrect assembly or modifications

Conditions of cover

Anchoring: on a prepared level base, anchored with the supplied ground anchors per installation guide. Failure to anchor voids the structural warranty.

Maintenance: inspect annually for surface damage at fastener points. Touch up any exposed steel with cold-galvanising spray within 14 days of noticing it.

02 · OUR PLEDGE
"

If your panel fails in a way that's clearly not been caused by impact or misuse, we'll replace it.

If your timber rots from a material defect, and you've kept up the every-two-years re-treatment, we replace the rotted section. Whether the strict warranty terms cover it or not. That's the deal.
