Cedar Maintenance Advice for Newly Built Homes

14 Jun 2023

Congratulations on purchasing your newly built Cedar home!

Cedar is a miracle timber if ever there was one: durable, long lasting, rot resistant and a superior insulator – warm in winter and cool in summer. Not to mention it looks stunning.

But like any outdoor timber, Cedar will require maintenance to stay in optimal condition.

New Zealand’s UV rays are some of the harshest in the world and they will eventually dry out the Cedar, leading to fine cracks and a roughening of the surface. This can commonly be seen in Cedar houses that have been left to “silver off”.

By starting Cedar maintenance early, you can get ahead of costly maintenance further down the line and keep your cladding looking just as beautiful as the day you moved in.

When To Start Cedar Maintenance

We recommend starting Cedar maintenance after two summers.

At this point, you may be wondering why we are talking about maintenance for a house that has just been built two years ago? Fair question!

While fresh Cedar boards do have a reservoir of natural oils that will keep them protected for longer, the boards have now been exposed to the sun for two summers and the natural oils are already being depleted.

It’s also worth noting that although you just recently moved, the Cedar may have been installed up to 3-6 months before that, so this process is well underway.

What Does Cedar Maintenance Involve?

For most new Cedar homes, maintenance consists of a soft wash and a recoat of sun exposed areas.

Our soft wash is an oxy-wash solution that removes any built-up organic matter – dust, pollen and spores – and leaves the Cedar fresh and vibrant.

Applying a recoat of oil will replenish the Cedar’s natural oils, fortify existing anti-fungal properties and enhance the colour tone, retaining the vibrant look of freshly installed Cedar.

After the initial treatment, sun exposed areas need to be maintained every 2-3 summers. The rest of the house may not need any maintenance for 5-7 years, apart from a light wash to remove built-up organic matter.

How Much Does Cedar Maintenance Cost?

This depends on the house size, ease of access and if scaffolding is required, but as a rough guide, the initial treatment of a single-story house with good access can cost anywhere between $4-5k.

A larger house with multiple stories can cost anywhere between $8-9k, plus you may need to include the cost of scaffolding on top of that.

However, after the initial treatment of the whole house, the cost of regular maintenance drops by 40-50% as only the sun exposed areas need maintaining.

If you have bought a Cedar house in a new development, chances are you are in the same maintenance schedule as the houses around you. By pooling together with your neighbours, we can often spread fixed costs (such as a cherry picker) across the all the involved parties.

Protecting Your Investment

A new house is an investment, possibly the most expensive investment you will ever make.

By regularly maintaining your Cedar, you are protecting the long-term value of your property and investing money now to get a higher resale value if you decide to sell.

Regular maintenance is also more cost effective than undertaking restoration just before you are ready to sell – and you will get to enjoy the beautiful look of freshly maintained Cedar while you are still actually living there!

How Often Does Cedar Really Need to be Maintained?

The quick answer is: not as often as you might think. On a wall that is not in the intense sunshine, Cedar will practically last forever.

Apart from being stunning to look at, Cedar is extremely durable, a superior insulator and genius at taking up deep-penetrating oil. Cedar’s worst enemy is not rain, or wind, or city grime; it’s the harsh New Zealand sun.

Left unprotected, UV rays will eventually dry out the timber, leading to fine cracks and roughening of the surface. This creates a toehold for mould, mildew and lichen to get established and make the timber look unsightly.

Regular oiling will prolong the beautiful look and weather resistance of your Cedar by penetrating deeply through the Cedar’s open cellular structure and replacing the natural oils lost over time.

Keep reading to learn how often you need to maintain your Cedar, or watch the video below for a quick summary.

What Does Regular Maintenance Involve?

For most Cedar homes, regular maintenance will consist of a light rinse once per year at the end of winter, then a recoat of exposed areas every 2-3 summers.

Cladding only needs to be maintained on a face that is exposed to the UV rays. The remaining faces will also benefit from recoating, but this might only be 2 or 3 times over a 15-year period. The treatment that is required is very dependent on the level of UV exposure and other environmental factors.

Think of it like washing your car. If you don’t wash your car for 12 months, all the dust, debris and contaminants from the road will stick to the body. It’s the same for your house, but not as easy to spot as houses are usually flat colours compared to a shiny paint job.

How Much Will Regular Maintenance Cost?

It’s a misconception that owning a Cedar home means you will be burdened with expensive maintenance bills. Compared to houses that require regular painting, Cedar works out far more economical.

The cost will depend on the unique requirements of each house. The main factors will be the size of the house, how many stories it has and ease of access. A single-story bungalow with good access might cost $2-3k every 2-3 years. For a multi-level property with difficult access, you might be spending $8k on scaffolding before you even start looking at the timber.

Regardless of the cost, regularly maintaining your Cedar will always be cheaper over the long run than painting, or the worst-case scenario, having to reclad due to the timber cupping and splitting.

Having a regular maintenance plan can help to spread out the cost and give you peace of mind that your investment is protected – and will look beautiful for years to come.

New Builds vs Older Houses

Newly installed Cedar has a reservoir of natural oils and tannins, and it will take longer for the cellular structure to start to move. You may not have to do anything for 5 years, but eventually the Cedar will start to dry out and you will need to slow that process down with regular oiling.

New Cedar will most likely be pre-coated, or coated on-site before it gets installed. There will usually be a booklet that comes with the house telling you how the Cedar has been treated and what kind of maintenance it needs.

For a pre-existing Cedar home, the new homeowner will need to ask the previous owners what kind of maintenance plan they had in place, or what products they have used in the past. If the Cedar has been stained and the stain is in good condition, then it requires a light rinse every year and a recoat every 2-3 years, depending on the level of UV exposure.

If you are unsure about the status of your Cedar, one of our team can come around and advise you on what treatment it has received in the past, and what is required to maintain the Cedar over the lifetime of the house.
