13 July 2023

At Dempsey Dyer, we supply and install a variety of timber windows for the trade.  When we supply wooden windows for the trade, it is imperative to keep them clean. You can ensure that it will last for many years to come. Timber windows stand out from the competition because they look fantastic.

Location is an essential thing to consider when you are installing wooden windows for your customer. If the window is facing south, this will benefit from more natural light, however they will be more vulnerable to the harsher elements. As a result, this results in more maintenance.

Let your customer know that there are methods they can use to look after their windows. In this article, we will go through some of these methods, so you get a clearer view. Read on to learn more.

Remove Dust From the Window

The first thing your customer should do when cleaning the window is to look out for extra dust on the top layer. This will remove the first layer of dust, saving a lot of issues in the long term.

Furthermore, you will need to keep an eye out for cracked spots and mildew, as this makes your home look unsightly in the long term. This could expose cracks in the paint that expose natural wood, being a heaven for all kinds of insects. It s imperative to treat these areas straight away.

Wash the Frame and Glass

Let your customer know that they should wash the timber windows thoroughly to get rid of mould and damp spots. This can be treated through a damp cloth or soapy water, ensuring that it will look in pristine condition. Ensure that the water is replaced when it gets dirty, and then give it a few strokes with a cloth to remove the residue.

Cleaning the glass is also easy because all you need to do is wipe it with a microfibre cloth and a combination of vinegar and water, and then it will gain a streak free shine. Another simple option your customer can use is washing up liquid with water to create a mixture, then use fresh water to rinse it off.  Wood is not immune to warping, but with this treatment, it will last for a long time.

Treating the Wood

Treating the wood is an essential component for your aluminium windows because you will want to make sure that it looks in pristine condition. If the area is rough, use sandpaper to smooth the edges alongside a putty knife. Then, leave it overnight to dry, and then trap moisture that decays the window.

If your customer is wondering how to protect their window, inform them that they will need a semitransparant strain that guards against sun and moisture. This results in a natural look that blends in with the wood and your customers’ property. To do this, apply one thick paint of coat, wait for it to dry for a couple of hours, and then apply the second paint coat.

Recoating the Paint

It is important to apply paint to the wood once a year which will help it look its best for longer. To recoat the paint, wipe it down with silicone abrasive paper to remove grease and dirt, then allow it to dry. Next, apply a microporous finish carefully without using it on the weather seals. This will cause damage and render them ineffective. Leave to dry for a couple of hours and it will look pristine.

 Dealing With Scratches and Chips

If the timber in your home is damaged, it is an idea to repaint it immediately, which will help keep it together. It can be susceptible to damage and chips easily, so the first thing to do is use a light abrasive to  lessen some of the damage, then remove it with a damp cloth.

Then, a timber filler should be used to make the surface smoother, giving you space to reapply the damaged area straight away. Wood is also susceptible to knots and grains, which rot over time. This can cause the wood to expand, so inform your customer that it is important to treat the wood regularly to maintain it.
