Replacing a timber deck: 5 signs you need a new deck

Written by Chris Constable | Sep 28, 2022 12:04:00 AM

Timber decks can last for decades with proper care and maintenance, but all good things do eventually come to an end. So, when should you replace your deck? We've listed five signs to look for and what to consider when it comes time to start replacing a timber deck.

Five signs that you need to replace your deck

1. Damage to the wood

Sunlight, mould, and weather can all do damage to your timber deck. It's a good idea to regularly inspect your deck to ensure there aren't any cracks or other surprises. Look for wood warping, check for rust on the fasteners, and test each railing.

2. Unstable footings

Do you have a sinking feeling whenever you walk onto your deck? If your deck is this unstable, it almost certainly needs to be replaced. This isn't the kind of issue you want to discover the hard way.

3. Wood rot

Wood rot (both wet and dry) is one of the most common problems in timber structures on the Sunshine and Gold Coasts. If this rot reaches your deck's structural timber, you run the risk of your deck collapsing. In many cases, this damage can be repaired without replacing your entire deck, but if you allow the wood rot to truly take hold, you will eventually have to replace the whole thing.

Signs of wet rot include:

  1. Discoloured or distorted timber
  2. Cracks in your timber
  3. Black or brown fungal growth on your deck
  4. Spongy timber

Signs of dry rot include:

  1. Grey strands on your timber
  2. Deep cracks along the grain of your timber
  3. Patches of brown or orange dust
  4. Large mushroom-like growths

In all cases, stay vigilant for a damp or musty odour in your deck, as this occurs with both wet and dry rot. Read more about how to identify wet rot vs dry rot, and what to do about it. 

4. Loose railings

If your deck has a few loose railings, a repair may be in order. Have us come to tighten or replace the screws that hold your railings on. If the vertical posts of your deck's railings are loose, however, you may need to entirely replace them instead. Loose railings constitute a significant safety issue on a deck, especially if you own a business, so it's critical to prevent them in the first place.

5. Mould and mildew

One of the most important things you can do to keep your timber deck well-maintained is to stay on top of any mould or mildew issues that crop up. For smaller mould issues, you may be able to take care of the growth on your own. Combine two parts of water with three parts of white vinegar, and scrub the deck thoroughly. Also, be sure to apply a mould inhibitor after it dries out. You may also want to do a patch test somewhere less visible on your deck to ensure the vinegar won't damage your wood.

If the mould or mildew is more pervasive, you may have to replace your deck instead. This is especially true if any of the other factors listed in this post exist.

Factors to consider when replacing a timber deck

If you're replacing your deck, there are many things to think about. Consider these aspects of replacing a timber deck:

Materials

Hardwood is by far the most popular material for building decks in Australia. We're particularly fond of using Merbau wood here at First Response, as it is extremely durable and resistant to insects and wood rot.

Budget

One of the first questions you should ask when replacing your deck is about the cost. You will most likely want to get price quotes from several contractors, but your budget shouldn't be your only concern. Consider the quality of what you're buying: it's always better to get something that will last for decades rather than something that will rot after only a few years.

Maintenance

You will want to choose a deck that you can easily maintain. All timber decks require regular upkeep, but the nature of this maintenance will vary based on the construction style and materials used. Make sure to regularly sweep off any dust and grime that build up on your deck. Do a deep clean of your deck every year, where you use a deck-cleaning solution to scrub out any mould or mildew that builds up.

Timeframe

The amount of time it takes to rebuild a deck varies based on the size and complexity of the job. The more timber you have to remove, the longer the job will take. Other factors that influence the timeframe of deck replacement include weather, availability of materials and getting planning approval.
