VertexGarden Rooms

Our guarantee

We build them to last, so we stand behind them in writing.

Vague “fully guaranteed” language is easy to write and hard to hold anyone to. So here's ours itemised — what's covered, for how long, and what isn't.

Structure & timber frame

A 10-year guarantee on the load-bearing frame, floor and roof structure we build.

EPDM rubber roof membrane

Covered against splitting and seam failure under the membrane manufacturer's warranty.

Aluminium doors & windows

Manufacturer guarantee on frames, glazing units and hardware, registered in your name.

Our workmanship

If anything we installed isn't right, we come back and put it right — same team, no quibble.

What isn't covered

Not covered: general wear, storm or accidental damage, and any alteration made by another trade after handover. Natural cedar is expected to weather and silver over time — that's the material behaving as intended, not a fault.

Because the person who quotes your build is the joiner who frames it, we're happy to put our name to it in writing — and to come back if we ever need to.
