Fence going green...

Bloodrayne · 25 Jun 2018 at 21:35

Hi all,

Having had such good advice on my first posts in this forum I'm going to continue...

My fence (as in, the one I have to pay to maintain) is beginning to show signs of green mould at the bottom of a few edges (it's feather edge/closeboarded - pressure treated, etc) it's not that old (apparently a year) but the neighbours are keen gardeners and have an array of plants against it that they excessively water nightly.

So, my question is - is it worth looking at some kind of preservative/treatment for the mould, is this something that would need to be done from the neighbours side, or is it best to just wait and replace rotten boards if and when it reaches that stage?

Thanks

I spayed mine with this

two days later all the green was gone.

I use it on the patio as well.

Household thin bleach will do the same thing if you want a cheaper alternative.

Apply the affected area with a spray bottle and within a few days the algae should disappear. Just be mindful of any run off as it will also kill grass or other plants.

If the timber was pressure treated properly to UC3 for whats above ground and UC4 for whats in ground contact it should be good for over 5 years without any extra protection, I would complain to who you bought it off.

When my fence went green it wasn't the timber deteriorating.

Getting rid of what I assume to have been algae growing on it just made it look better.

The other side of the fence gets more sun and didn't have any algae to treat.

Sorry for the delays in coming back to this one - the fence is going green, but the wood itself seems to be fine - so not sure if it warrants the complaint? It's more of a cosmetic thing currently, but I have become sensitive about fencing over the years due to a few disputes with neighbours (including one that thought replacing a 6ft timber fence with knee-high chain link was acceptable) so perhaps obsess more than I need to...
