I am always saddened when asked to replace good quality hardwood windows after only a few years – simply because they were not properly treated/stained BEFORE they were installed. So here are some pointers on what to look for if your timber windows and/or doors have not been treated with a preservative and/or stained correctly so that you can get them fixed before it becomes a problem:
1. Rot/degradation in areas that are not easily seen once the window is fitted, as can be seen in photographs 1 & 2. This means that the timber was not treated properly prior to the window being installed. The problem here is that this allows rot to progress without the home owner seeing it and therefore unaware of what is happening, until it is too late. Solution – only buy timber windows that have been properly treated with a wood preservative and/or stain BEFORE they are fitted.
2. Photograph 3 shows the underneath of the cill without any protection from a stain nor is there any evidence of sand mastic or silicon sealant having been applied behind the drip, this means that there was no physical barrier to stop the water being driven underneath the cill resulting in ingress of water into areas of your house that you don’t see and more than likely resulting in degradation of the new window and worse causing dry rot within the building. Solution – check your window cills have been sealed with a good quality silicon sealant and it is installed behind the drip – this is especially important if you buy timber windows on a supply only basis and you joiner needs to cut the cills – ENSURE PRESERVATIVE IS APPLIED TO THE ENDS BEFORE IT IS INSTALLED .
3. Photo 4 shows the groove/slot formed for the pivot hinge to be fitted into and again no stain has been applied before the hinges are fitted in the workshop which means the stain protection system is not complete and is not protecting the timber, resulting in a breakdown of the stain system on the surfaces and rot on all surfaces. Solution – only buy timber windows that have been properly treated with a wood preservative and/or stain all over before window locks, hinges, etc are fitted.
4. Photo 5 shows a gasket fitted into a groove in a timber that has not received any stain either, which provides exposed timber that can take on water and cause degradation of the stain system on the exposed surfaces and rot on all surfaces. Solution – again only buy timber windows that have been properly treated with a wood preservative and/or stain all over before gaskets etc are fitted.
It is very difficult to explain to potential clients why the same specified windows on paper can attract very different prices from different Companies. However hopefully these photographs and our explanation of what will happen if timber windows are not treated with a preservative and/or stain prior to manufacture and installation will go some way towards explaining what can cause a difference in the quoted price.
We, here at T J Ross, strive to ensure that all surfaces of our windows, doors, screens and all other external joinerwork are fully protected with the stain chosen, so our clients can sleep without worrying what is happening to the unseen parts of their windows and doors. To achieve this we actually dry fit all the ironmongery and then remove it prior to the product going through our spray shop so that all exposed surfaces are coated with the protective stain – it does cost a little bit more but it’s well worth it and gives a better sleep.
