Cedar wood windows and cladding

Foleyart

I had a query posted on another site on boards and was told to try here with my problem. Cedar wood windows and cladding, one year on and it is begining to show signs of weathering. My wife is worried about blackish spots. It was well treated before it was put in with some expensive stuff I cant remember the name of, about 4 coats. Should I just leave it, or is there something I should apply?? I would appreciate any help on this.

Hi I have looked into a good few timber log cabin constructions for friends and customers over the years that are being sourced and sold in to this country from abroad with a different climate to our own and have found with all of them with out fail have been visited by the green fungus and black spot wet rot, and these were samples homes on show up maybe five years tops when I inquired about the durability and maintenance required not one of them had any long term answers for ten twenty thirty years regarding this country and our damp climate but could ream off quoted figures sourced from the manufacturer abroad........

Sorry for the rant having said that you can buy commercial cleaners to remove and treat the green fungus witch may be back depending on the orientation of the house
The black spot is a condition of wet rot and is permanent

Question are your windows and siding red or white cedar

Find out what product was applied in the first instance as it will have a bearing on how you repair and finish the cedar

I would personally have the house professionally looked at as cedar is unique to our environment and in making sure any repairs and finishes are carried out to a good standard

ps I have been fortunate to be able to work with many species of timber in my profession and in many applications but they all have their limitations, our climate is just tough on timber regards jbcford

For such a specific query I would recommend posting the same question (or doing a search) on a UK forum, either

http://www.ukworkshop.co.uk

which has many posters who seem to be experts

or

http://trevera25.proboards85.com/index.cgi#woodworking

which has some of the expert members from the first forum who left it after an 'unpleasantness' apparently...

I have some books on timbers and uses but they are on loan at the mo... I will check them when I get them back. I would have thought the Cedar would be durable in our climate which isn't so different from Northern Countries (Norway, Finland etc) which is probably where your windows came from...

Cheers
Joe

Thanks for the input guys, I got the windows and cladding from Dalgan in Galway.

Maybe you could post a couple of pictures to get a clearer view of your problem, and hopefully a solution for you.

I'm probably stating the obvious here, but you should also talk to the company that provided/installed the windows as I would hope that they provide a warranty of more than 1 year. If what you describe is more than cosmetic damage (and perhaps even if it is just cosmetic damage) then there may be an onus on them to repair/replace the affected wood.

And even if this is not covered by warranty, they might be able to provide info on how to tackle the problem as they may have encountered the same problem before.

The Proper treatment for Cedarwood, ( usually western red Cedar imported into Ireland) is an Oil like Tung Oil or something similar, this will keep the colour and protect the wood, otherwise, Cedarwood will eventually turn a silver colour with some cracking. Oiling must be done once a year.
