Townhouse Complex Stripped Back & Rejuvenated

This block of 14 townhouses is located on an elevated section overlooking the beautiful seaside suburb of Mission Bay.

The townhouses were architecturally designed by Novak + Middleton and built by Gibbons Co. The townhouse exteriors use an eye-catching mix of standing seam metal cladding and Cedar.

The townhouse complex was finished in 2020. After a few years in the sun, the owners started to notice the Cedar looking patchy and uneven.

TimberTech was bought in to assess the Cedar and put a management plan in place to keep it protected – and looking great – for years to come.

Maintenance Timeline

TimberTech was first contacted on the 25th of October, 2024.

1st November, 2024 – Cedar Assessment completed.
25th November, 2024 – Quote sent.
31st July, 2025 – Job started.
29th August, 2025 – Job completed.

As there are 14 houses in the complex, each needing consultation, the time between the different stages of engagement was longer than usual.

After an 8-month consultation period, 12 out of the 14 houses in the complex decided to go ahead with the proposed work.

The job took around 4 weeks in total, with some delays due to inclement weather.

Cedar Assessment

Sometime during the building process, the Cedar was coated with stain. Stains are excellent in areas without direct sunlight, but when exposed to harsh UV they break down, giving a patchy or uneven look.

Unfortunately, the stain used here had broken down, particularly on the exposed northern face.

Our recommendation was to fully strip, sand and recoat the Cedar cladding, converting it from stain to a penetrating oil (in this case, Wood-X).

The stain used on the south face still held up well, and we recommended that another coat of the same stain be used to extend its lifespan.

Cedar Maintenance Process

Stripping stain from Cedar is a laborious task and not something undertaken lightly.

For stripping this particular stain, Resene Sea to Sky Coating Remover has proven very effective. We apply this with a spray machine, making sure all the joinery, doors, flashings and surrounds are masked to keep them protected.

The stripper is left on for a couple of hours to activate and dissolve the stain, then it can be scraped off, followed by a wash to remove any last residues.

For particularly stubborn areas of stain, some sanding may be required. This should be done lightly and kept to a minimum to retain the texture of the board.

Once the stain has been successfully removed, the board is ready for oil to be applied.

When first assessing the job, we knew we needed to match the colour of the oil as closely as possible to the original product. We presented the owners with some colour options and settled on using two colour tints, Flint and Foundry.

The boards were very dry, especially on the northern face, and required two coats in most places. We basically put as much oil into the boards as possible.

Cedar Maintenance Challenges

Some of the more sheltered townhouses had stain that hadn’t fully broken down yet and proved difficult to remove. We had to remask and restrip these areas before we could apply the oil, ensuring an even finish.

The other main challenge was keeping the whole area tidy and minimising the impact on the residents, particularly the owners who were not having any work done. We did our best to minimise any noise, only have essential vehicles in the car park and provide constant communication with all residents.

One of the biggest downsides of moving from stain to oil is a 3-9 month transition period where your Cedar will have a shiny-flat-shiny-flat look.

This happens when oil is applied to any surface that still has stain remnants. The oil cannot soak through the stain as it is non-porous, so it sits on top, around the surface area where the oil has soaked in, giving the shiny-flat-shiny-flat look.

This is all part of the process and not exactly a challenge, but we always take care to prepare the homeowners for the transition period.

Ongoing Maintenance Requirements

When transitioning from stain to oil, we recommend assessing the Cedar again after 3 months to see if any of the boards require additional oil, especially on the sun-exposed faces.

We will then recheck the boards 12-18 months later (depending on the conditions), after which the Cedar will fall into a regular maintenance plan, with exposed faces needing to be recoated every 2-3 summers.

The Final Outcome

The rejuvenated Cedar was transformed from washed-out brown to a lustrous dark chocolate tint. The owners were impressed with the final look and relieved that their Cedar had been returned to the state when they moved in.

By transitioning from stain to oil, they could also look forward to more straightforward and cost-efficient maintenance in the future.

Stripping Back 8 Years of Moss & Lichen

This modern, 2-story home is located in the leafy suburb of Titirangi, a beautiful area far from the bustle of the city, but which also has a lot of tree cover and higher than average rainfall, creating the perfect environment for moss and lichen to grow.

The new homeowner contacted us while waiting for the home to go unconditional. The Cedar hadn’t been maintained in 8 years and was looking shabby and discoloured.

Cedar should be treated every 2-3 summers to keep it protected from New Zealand’s harsh UV rays, and to keep it looking cosmetically beautiful.

Without regular maintenance, the 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 makes the timber look unsightly.

As the Cedar was left such a long time, the story of this property can be told in the before and after photos. We don’t usually have such dramatic transformations with most houses we maintain, so it was a real treat to see how beautifully the Cedar tidied up.

Maintenance Timeline

The customer first approached us on the 14th of October, 2020.

16th October, 2020 – Initial onsite assessment completed.
22nd October, 2020 – Quote sent.
26th November, 2020 – Team arrived onsite to start the job.
9th December, 2020 – Job completed.

The job took 72 hours in total: 14 hours to wash and strip the timber in preparation for the coating, and 58 hours to apply the stain. The entire job took 9 days from start to finish.

Cedar Maintenance Process

Cedar that has been sheltered from UV rays has a flat, uniform surface that is straightforward to maintain.

Cedar that has been exposed to high amounts of UV will have broken-down stain or oil still on the surface, which often creates a toehold for organic matter to grow.

The two front faces of this Cedar home demonstrate both situations perfectly.

The sheltered face, next to the front door, has a flat even colour; while the exposed face, above the garage door, has been exposed to the UV rays.

The starting point for both faces is the same: the Cedar is washed using a biodegradable cleaning solution to remove organic matter and any remnants of the broken-down stain.

After the deep clean, the sheltered face was ready to be coated.

The exposed face required a more rigorous cleaning process. The orange colour on the Cedar is mould, an organic growth that washes off quite easily during the deep clean.

The dark brown sections of timber are stain that hasn’t been broken down by the UV and is still in reasonably good condition. To remove this and get the boards back to a natural state, we had to strip the boards.

The stain used on this property is Resene Woodsman Waterbourne, smokey ash colour. This is a very light-coloured stain, one of the lightest on the market, and it leaves the boards looking natural and warm in tone.

Cedar Maintenance Challenges

Soffits keep moisture away from the roof and help prevent wood rot and mould, but they also shelter the Cedar from UV rays. This sounds good in theory, but often makes the Cedar under the soffits darker than the Cedar exposed to the light.

If these areas are not prepared properly, the finished result will look odd as both stain and oil are translucent and will show whatever is on the surface below. Preparation here is key, and it takes experience and expertise to make sure the surface is even before applying the treatment.

This property also had two high faces over 4 meters that required scaffolding. As the ground below is flat, we were able to use our mobile scaffolding which kept access costs down.

Ongoing Maintenance Requirements

Now that the whole house has been restored, it’s only the sun-exposed faces that will need maintaining every 2-3 summers. The rest of the house may not need further maintenance for 5-7 years.

The Final Outcome

Location matters with Cedar. In an area with lots of tree cover and rain, the boards are often in good condition, but covered in lichen, moss and all sorts of organic material, and they are more susceptible to moisture damage.

That’s nothing out of the ordinary, but it does require some extra work if the Cedar is not regularly maintained.

The new homeowners were delighted with the result. Their newly purchased home cleaned up even more stunning than they imagined, especially the front facing areas that people first see when arriving.

This property is an excellent demonstration of how resilient Cedar really is. An amazing timber that will look great for years to come, with a little love and care.

Cedar Beautifully Restored After Maintenance Mishaps

This stylish, modern home in Swanson was built in 2016, but soon ran into problems with the appearance of the Cedar.

The building company had used a stain product that wasn’t tested in New Zealand conditions and soon deteriorated in the harsh UV rays, becoming porous and exposing the Cedar to the elements. Air borne mould took root in the timber and quickly spread once the moisture got in.

As the house was relatively new, the homeowner was understandably upset. Thankfully, the building company did everything to make things right – including bringing in TimberTech to give our expert advice.

Maintenance Timeline

The building company first approached us on the 23rd of September, 2020.

27th September, 2020 – Onsite Cedar assessment completed.
29th September, 2020 – Quote sent.
14th December, 2020 – Team arrived onsite to start the job.
25th January, 2021 – Job completed.

The job took 3 weeks in total, with some time off over the holiday period.

Cedar Maintenance Process

We first masked all the areas that were adjacent to the cladding and stripped off the old stain using a paint stripper.
Modern paint strippers are less potent than in the past and are made from organic compounds, which are harmless to gardens and more environmentally friendly.

Once the paint stripper had been applied, we scraped the weatherboards and removed all traces of the old stain and stripper. To prepare for the new treatment, we lightly rinsed the surface with a water blaster to remove any remaining dust and organic matter, then sanded the boards to take away any of the furring.

The final step was to apply 2 coats of an oil stain. Oil-borne stains are oil mixed with solvents that evaporates upon application, allowing the stain to cure. These types of products are not used as much these days as the market has shifted to waterborne products that are more environmentally friendly.

Solvent based products give a much flatter finish that absorbs the light, giving a less shiny, more natural look.

Cedar Maintenance Challenges

As the house was basically new, we had to take special care masking around the edges of the timber to ensure the oil stain didn’t come into contact with the joinery, or the established gardens.

The awning on the front face of the house also had to be removed. We supplied and erected mobile scaffolding to give the builders access to the awning.

Another challenge for this particular property was liaising between all the concerned parties to achieve a satisfactory outcome. This included the customer, the building company and the company that supplied the initial product.

TimberTech has the staff and the experiencing to manage jobs of all sizes and we gladly took on the management of this project – which proved to be a great relief for the customer.

Ongoing Maintenance Requirements

To keep the Cedar looking beautiful for years to come, all it needs is a light wash once every few years and a recoat of exposed areas every 2-3 summers.

The Final Outcome

The final outcome was an outstanding transformation. The Cedar has a smooth, even finish that is free of mould and still retains the natural textures that make Cedar look unique.

We are very proud of the restoration work done by our team, but the highest praise came from the customer, who sent us an email soon after the work was completed:

“I wanted to let you know how pleased I am with the work completed at my property, it’s now looking fab. I was particularly impressed by the team, they did a fantastic and thorough job, they demonstrated an excellent work ethic and they were very easy and trustworthy to have around. I’d like to schedule regular maintenance for the cedar – please let me know what I need to do to lock this in. Thanks again for all the hard work – excellent job!”

Commercial Cedar Restoration in the Heart of Hobsonville

Brickworks is large, mixed-use complex spanning an entire block in Hobsonville. The complex is comprised of 4 buildings situated around a central parking court and rain garden, with 60 residential homes and additional commercial units at the street level.

The mixed-use nature of the development was designed to be the commercial heart of the surrounding suburb and the appearance of the building is integral to its success.

Clad in an eye-catching mix of bricks and Cedar, the aesthetic is based on the industrial buildings that were once present on the site and pay tribute to the rich history of the area.

The building was finished in May of 2015. The original intention for the Cedar was to let it weather naturally and give the building a silvered look.

However, the rates at which the Cedar was silvering were inconsistent depending upon the orientation of the timber and the building was starting to look patchy and uneven, with some watermarks on the surface.

Up until then, the body corporate had been getting the Cedar soft washed every year but were unhappy with the results. To show the difference between a soft wash and a deep clean, we first did a demonstration on an isolated wall.

The initial results were striking and TimberTech was awarded the contract to maintain the building over a 10-year period.

Maintenance Timeline

The body corporate for Brickworks first approached TimberTech in March of 2020.

2021, August – Deep clean and recoat the entire building.
2022, May – Recoat the sun-exposed dry faces only.
2024, Oct – Soft wash, recoat the sun-exposed northern faces and assess the other faces.

In general, sun-exposed faces should be recoated every 2-3 summers to protect the Cedar against the elements and keep it looking great all year round.

As part of the 10-year maintenance plan, we are scheduled to wash and recoat the entire building in 2026, recoat the sun-exposed dry faces in 2028, then recoat the sun-exposed dry faces and assess the other faces in 2030.

Cedar Maintenance Process

As the original intention had been to let the building silver naturally, the Cedar was in a natural state with no oil or stain.

Upon first inspection, the northern face was dry as a bone. The remaining faces were faring better, but still in need of treatment to protect against future wear and tear.

We started with a deep clean of the entire building to remove the oxidised timber fibres responsible for the Cedars patchy, silvered look. The Oxyclean solution also removes all the dirt, grime and organic matter, restoring the natural timber tones.

Once clean, the timber was treated with a tinted penetrating oil developed by Wood-X.

As the Cedar had not been treated previously, the initial application of oil was quickly absorbed by the dry timber. We then needed to return 6 months later to give the entire building a second application.

Cedar Maintenance Challenges

The main challenges for the project were the height of the buildings, the sheer size of the complex and access management.

Brickworks is four stories high, and most of the apartments have Cedar balconies that jut out from the main structure. To work safely at this height, we scaffolded whole sections of the building at a time and used a 28-meter knuckle boom for added versatility.

The configuration of the complex – basically a rectangle with one side that runs along a main road, heavy with car and foot traffic – meant that we had to manage traffic and operate in a dynamic environment, following strict health and safety procedures.

Cedar had also been used on the inner faces of the buildings above the gated carpark, which required us to work with the residents to organise ongoing access.

The Final Outcome

The whole job took 6 weeks in total. There was a lockdown midway through the project which pushed the job out, but in ideal conditions a project of this size takes around 4-6 weeks.

The body corporate, residents and shop owners were all amazed by the transformation. This was a prestigious building upon completion and there was no reason for it to age prematurely.

After deep cleaning the Cedar and treating it with oil, the look turned from shabby grey to a golden-brown lustre. With regular maintenance, there is no reason why it can’t look fresh and vibrant for years to come.

Our team was also stoked with the final outcome. This was a complex job with a lot of moving parts, and the team pulled it off flawlessly.

But don’t just take our word, head over to 160 Hobsonville Point Road and see for yourself!

With the rise of Cedar as a preferred cladding for apartments and office buildings, this type of work is only going to grow more specialised. TimberTech has the expertise and the experience to manage any job, no matter the size or the scope.
