Rotting Window Frames in Housing New Zealand House

This has been an ongoing battle for us as most of the bedroom's have extensive rot in the window frames caused by the excess buildup of moisture in the house and leaking windows. We have requested that the Rot be repaired several times resulting in Housing New Zealand sending a contractor our to scrape away the rot and fill the hole with filler or bog.

I have no problem with this method of repair if its done properly however the fact that within a short time frame wither the rot returns or the surrounding area begins or continued to degrade means that the job was not completed correctly in the first place.

There are also issues such as the symptoms such as the rot have been repaired but the cause remains.

Yesterday after months of battling and claims in court by the tenancy manager stating that the rot had been repaired contractors turned up to finally conduct these repairs. It is not my place to ensure the work is done correctly but keeping in mind that this rot is in a bed room and as a family we are already suffering from some nasal infections and respiratory problems I decided to take a few photos of the repair.

Originally the contractors stated that the entire frame should be replaced as the rot is extensive however HNZ sent a work order for them to just bog up the problem. As you will see in the photos this has been done several times before as there is existing bog work.

This is pretty much the extent to which the rot was scraped out before the hole was filled, it is pretty clear that not all of the rot was removed and that the problem penetrates muchh deeper than is visible as there is substantial rot underneath the are that was previously filled.

Anyone with even partial knowledge of handyman work or building knows that you can not or should not bog over wet wood. The dark patch in the corner is wet rotted wood and is very soft. This was not removed before filling and I suspect that if it had been the hole  and possibly rot would have extended through the sill and into the framing.

To my knowledge the wood used for sills is 25mm thick pine, the depth of the visible are is pretty close to that.

A quick search on the net turns up many articles as to how to repair rotten window sills, probably the simplest one and easiest to follow is one from Diane Stevens published on eHow.

Although this process uses a specific repair kit it highlights the fact that the remaining wood needs to be be stabilised and the assumption can be made that this is to prevent further or continuing rot.
