Your decking installation guarantee

Choosing your deck installation team is a big decision. How can you be sure that your new decking will be everything that you hope for; well-made, properly constructed, long-lasting? At Deckbuilders, we guarantee this for you.

Every single deck that we design and build is backed by our triple guarantee. You have total peace of mind as we create your new outdoor space for you.

Our comprehensive guarantee covers three key areas: component longevity, structural indemnity and workmanship.

Your new decking will be guaranteed for:

  • 12 months against workmanship and defects
  • 5 years against defects in structural components, footings, columns, beams, joists and railings
  • 10 years against the failure of any timber element due to fungal decay and insect attack

Remember: we pressure treat all your timber to Hazard Class 4 as standard. This is a higher specification of treatment for most timber used in decking installation.

Deckbuilders are a great team. Excellent planning and communication. The project management of the build phase was impeccable and even accommodated late changes without any fuss or problem. We are just thrilled with the overall finished project.
