Stunning Transformation of Lichen-Covered Home

This architecturally designed home is located along the eastern coast of the Whangaparaoa Peninsula, with magnificent views across Stanmore Bay.

The home was built in 2009 and the Cedar had not received any maintenance before the customer contacted us.

Cedar located along exposed coastlines has different requirements than Cedar in tree covered areas. Without any shelter, the Cedar is fully exposed to the harsh New Zealand sun, which can burn the timber fibres on the exposed faces and dry out the boards.

Coastal winds can also be strong and contain higher amounts of organic matter, such as dust, pollen and sea salt.

Due to the lack of maintenance and exposure to the elements, this Cedar home required a complete restoration.

Cedar Maintenance Process

Before oiling, the Cedar required a deep clean to remove all the built-up organic matter and burnt fibers on the surface of the timber.

The customer wanted a golden look for the Cedar. We used Wood-X penetrating oil in Kauri Gum, which is the most popular and natural Wood-X colour tone.

As the front of the house is the main feature area – and the faces most exposed to the sun – we allocated more time and materials here to make sure it looked stunning.

The colour of the garage door (in the before photos) shows what the boards would have looked like if they had been washed previously.

Unfortunately, the garage had been water blasted by someone unfamiliar with Cedar, leaving the surface streaky and damaged. Because the timber is so soft, these lines will stay in the timber forever, unless they are either washed or sanded out.

Above the garage door, the boards have been oxidised by the sun, giving them a burned and blackened appearance.

After putting drop cloths down, we sprayed oil from the bottom up, then across the boards, and by the time we got to the top corner, we had to start again as the oil had already been sucked into the timber.

This was coated 4 times in an hour, and the section above the garage door alone would have used 1.5 litres of oil.

We then left it for 24 hours and came back the next day to apply another coat, mainly because it’s a feature area and we wanted it to pop, rather than still look thirsty.

On the face running perpendicular to the garage door, the boards have been bleached by the sun. Walls facing to the west can sometimes get just as warm and weathered as the northern faces, especially if there is no tree cover.

We recommend that sun-exposed areas are recoated every 2-3 summers. As these boards were so dry, we will return in 9-12 months for a recoat.

This gives the oil a chance to really suck into the pores of the timber before adding more. If done any sooner, the oil will sit on the surface and wash off when the rain hits.

Cedar Maintenance Challenges

The biggest upfront challenge for this job was how steep the property is at the back. As shown in the photos below, the house is built on a very steep coastal hill and required extensive scaffolding.

The next big challenge was just how dry the Cedar was.

The boards used for many Cedar homes are scalloped at the bottom, so that they overlap the board below and sit flush. The boards on this home are solid timber without any decorative features, allowing the boards to sit on top of one another.

They are not much thicker than standard boards, but the difference is that the thickness goes all the way down. This thickness makes the boards very durable, as the thinnest part of the board is where most of the cupping occurs.

The thickness of the boards, along with how dry they were, required more coats of oil than usual and anyone untrained in Cedar maintenance might have slapped on a coat of oil and called it a day. The end result would not have been pleasant to look at.

The Final Outcome

The restored Cedar makes it look like a brand new house. Contrasted with the grey schist, the lovely golden hue creates a timeless alpine look, both homely and sophisticated.

The owner was away while we did the maintenance and was stunned by how it looked upon their return. They knew we would make it look better, but they didn’t think the transformation would be so dramatic.

Even Mark was impressed with how well the Cedar polished up, and that saying a lot having been in the business for 30 years! What a fantastic result for the homeowner, and a restoration we are very proud of.

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.

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.
