​​​​​​​warranty

A Gabriel Ash greenhouse is designed and manufactured to last for many years, and our extensive experience over the years allows us to confidently offer a 12-year warranty.​​​​​​​​​​​​​​

When it comes to greenhouses, we're experts. Then again, we've been engineering and constructing greenhouses for years and are always looking for ways to improve them. It's easy to see why hundreds of customers purchase our greenhouses and coldframes every year.


All products are designed and manufactured to last for many years and form the framework for people and the good life, whether it is primarily for cultivation or as an oasis in the garden.

That is why we are willing to provide a 12 years warranty.

Experience Peace of Mind with Our 12-Year Guarantee

When you invest in our products, we want you to feel confident that you're getting the very best. That’s why we offer an extensive 12-year guarantee to back up the quality, durability, and craftsmanship of our goods. Here’s why our warranty is worth celebrating:


12 Years of Confidence

From the moment your product is delivered, you're covered! For the next 12 years, rest assured that your purchase will be free from manufacturing defects. Here’s what we promise:

  • Top-Notch Quality: Every item you receive from us will meet a high standard of quality.
  • Perfectly Fit for Purpose: Your product will do exactly what it was designed to do.
  • True to Description: What you see is what you get! The product will match the description you received when placing your order.


Quality Craftsmanship, Guaranteed

We take pride in the workmanship and construction of our products. However, we do recognise that some things are beyond anyone's control. Our guarantee covers any manufacturing issues, but here are a few situations that aren't included:

  • Natural Evolution: If you’ve purchased products made from beautiful Western Red Cedar, it's natural for the timber to change colour over time, which adds character to the wood. Natural materials like timber may experience shrinkage, cracks, or knots over time, which are all normal and part of its charm.
  • Life Happens: Our guarantee doesn't cover damage caused by accidents, improper storage, or failure to follow our care instructions.
  • Acts of Nature: We do our best to create products that stand the test of time, but extreme weather conditions like heavy rain or strong winds fall outside the scope of our guarantee.


Easy Maintenance for Lasting Beauty

We design our products to last, and with just a little care from you, they’ll remain in great condition for years to come. Small maintenance tasks, like adjusting windows or tightening screws, will ensure everything continues to work smoothly. These simple steps are your responsibility but are a breeze to keep on top of!


Unique Timber, Built to Last

Each piece of timber we use is truly one of a kind. While we can’t guarantee the longevity of every individual piece of wood due to its natural variations, we do offer something even better: a 5-year guarantee against rot on our beautiful Cedar framework. You get the beauty of natural materials with added peace of mind.


Accessories Covered Too!

Moving parts like auto vents and blinds? They’re covered too! You get a 2-year guarantee on these essential accessories.


Your Rights, Our Promise

Our guarantee is here to enhance your peace of mind and doesn't affect your legal rights. If you ever feel something isn’t quite right with your product, don’t hesitate to seek advice from your local Citizens' Advice Bureau or Trading Standards office.


Constant Innovation, Always Improving

We’re always striving to make our products even better. From time to time, we might upgrade components, accessories, or technical details to enhance your experience


Your Guarantee, Your Peace of Mind

Finally, your guarantee is just for you! It’s our promise to you as our customer and isn’t transferable unless we agree otherwise.
