The written warranty
Our guarantee
Timber buildings are guaranteed against rot for 15 years — cladding, framing and flooring. Composite cladding is warranted for 30 years by its manufacturer. This page is the whole promise, in plain English — the same one written into our terms.
Timber buildings — 15-year anti-rot warranty
Cladding, framing and flooring, guaranteed against rot for 15 years. We can put that in writing because the framing timber is tanalised — preservative driven deep into the cells under pressure before we cut a single joint, not brushed on at the end.
How tanalising worksComposite buildings — 30-year manufacturer warranty
The composite cladding is warranted against rot and decay for 30 years by its manufacturer, and the tanalised timber framing underneath carries our own 15-year anti-rot warranty. The same conditions and exclusions apply to both.

When our team installs your building, the workmanship carries a 1-year warranty. Anything we got wrong in the build, we come back and put right.
What keeps it valid
Timber lives outdoors, so the warranty asks you to look after it. Five habits — all written into the terms, none of them hard:
- Treat the building with a high-quality oil or spirit-based preservative within 30 days of installation, then at least once a year — inside and out
- Treat any timber you cut, drill or notch with preservative at the cut
- Silicone-seal the windows inside and out
- Keep plants and stored items clear of the walls, keep air moving through the building, and keep the roof covering sound
- Talk to us before making structural alterations
Our maintenance guide walks through the lot — it amounts to an afternoon a year.
What it doesn't cover
The exclusions, in plain English — the same list as Section 15 of the terms:
- The natural character of timber. Knots, small surface splits, seasonal movement and colour variation are how wood behaves outdoors — they don't affect the structure and they aren't defects.
- Base problems and ground movement. The base is your responsibility, and an unsuitable one is the single biggest cause of door misalignment and gaps. Get it right first with our base preparation guide.
- Storm, flood and weather damage. Insure your garden building as part of your home contents or buildings policy, the same as a garage.
- Roofing felt wear. Felt is a wearing part with a service life shorter than the building's. If you'd rather never think about it, the EPDM rubber roof upgrade replaces it.
- Condensation and mould. These are ventilation and usage matters — keep air moving and they don't start.
- Glass after handover, and unauthorised alterations. Glass breakage once the building is handed over, and alterations, additions or repairs we haven't agreed to.
This warranty is in addition to, and does not affect, your statutory rights. The full written warranty is Section 15 of our terms — this page and that section say the same thing, on purpose.
Making a claim
Send us your proof of purchase and clear photographs of the problem. The warranty applies to the original purchaser at the original installation address and isn't transferable. Where a fault is ours, we normally supply replacement components — faster than fussing with a whole building.
