Frequently Asked Questions

How to repair damaged decking?

Repairing damaged decking involves several steps to ensure your deck’s structural integrity and aesthetic appeal. Here’s a general guide:

Assessment: Start by thoroughly inspecting your deck to identify any areas of damage. Look for signs of rot, cracks, splintering, loose or damaged boards, and rusted or corroded fasteners.

Replace Rotten or Damaged Boards: Remove any rotten or damaged boards by unscrewing them from the deck frame. Use a pry bar to lift stubborn boards if needed. Replace them with new boards of similar size and material. Ensure the replacement boards are properly aligned and securely fastened to the deck frame.

Is it worth repairing decking?

If repairs are merely a temporary solution to more extensive damage and will need to be done yearly, or even more often, to keep the deck safe and in good condition, it’s better value for money to replace the deck. In this case, replacing the deck should also save you time in the long run.

How is decking fixed?

Fixing decking typically involves addressing various issues such as loose or damaged boards, structural problems, and cosmetic imperfections. Here’s a general guide on how decking is fixed:

  1. Identify the Problem: Begin by inspecting the deck thoroughly to identify any issues that need to be addressed. Look for loose or damaged boards, protruding nails or screws, structural instability, rot, mold, or mildew.

  2. Secure Loose Boards: If you find any loose boards, use a screwdriver or drill to tighten the screws or nails holding them in place. Replace any damaged fasteners with new ones if necessary.

How many years will decking last?

On average, timber decking lasts for between 15 and 30 years. With the right care and maintenance, your decking can last for decades come rain or shine. In this guide we’ll talk you through how to clean decking, how to strip decking as well as how to protect your deck and what to do with weathered deck.

What is the best treatment for old decking?

Decking stain will give your decking plenty of protection as well as a fresh look. Before you apply your chosen stain, pour some water onto your deck. If the wood absorbs it within ten seconds, it’s ready to be stained. Once you’ve applied your first coat, let it dry and then apply a second.

What is the longest lasting decking material?

In comparison to wood, PVC, aluminium, and steel, composite decking is the longest-lasting material for your deck. Its overall longevity, aesthetic qualities, and low maintenance make it the most desirable material to use.

Which type of decking is best?

Decking of composite is the most weather-resistant material and requires nearly little maintenance. If you want to build a beautiful deck that will endure for a long time, composite decking is the best option, whether evaluated in terms of long-term investment expenses or time saved on maintenance.
