How to install a deck: do I need professional help?

Deciding to install a deck yourself will depend on the complexity of the design. If it is a simple, ground level deck on a flat area that is not too large, you might choose to undertake it yourself. If however, the design is much larger or on a sloping site, or incorporating multi-levels or design features such as seating, employing a competent installer is a sensible option.

Within TDCA membership, we have several professional deck designers and installers. Some will undertake work in a specific area whereas others travel more widely. Hiring professional help, with third party quality accreditation (such as DeckMark) is a good investment.

Learning how to install a deck yourself is not easy if you have not done this sort of work before. However it is possible. We would recommend that you do as much research as possible before you start the project. You might also wish to acquire the help of a friend or family member and ensure that you have plenty of time to complete the project.

Decking projects are generally undertaken in the warmer, dryer months from spring to early autumn. It is at this time that the ground is easier to work with – nobody wants to install a deck in a mud-bath!

If you are considering installing a deck yourself, don't forget to take into account the following factors: 

• Planning permission (if required)
• Timber species
• Correct softwood timber treatments – Use Class 3 is generally acceptable for deck boards, whereas Use Class 4 will be required for timber that will have in-ground contact
• Deck fixings and the tools required
