Posted on August 12, 2018.

Once you’ve made the decision to purchase Timber windows, it’s important to know how to care for them as they are a natural product and do require some attention. Here we explain how you can care for and get the most out of your timber windows for the longest time possible.


Once you have selected your beautiful windows, you need to ensure they are installed correctly. At Original Windows, we take care of all aspects of installation for you and here is what helps us prepare for a great fit, every time.

We ensure that all surfaces and edges are in a good condition before applying any finishing coats. We make sure that finishing is carried out in dry weather using high quality materials and we make sure that primed windows have at least one finishing coat applied to the back side before installation.

General Cleaning:

We recommend cleaning your timber products at least twice a year to help maintain their pristine looks. For general cleaning, use a soft cloth and water with soap or washing up liquid. To remove any grease marks that have occurred, apply washing up liquid mixed with a little water, before rinsing for clean water. You should never use glass cleaners on the frames and don’t use a kitchen or bathroom cleaner in case these stain the wood. Remember, wood isn’t indestructible to taking care of them will make your products last far longer than their guarantees

To Recoat:

It’s recommended to inspect the surface coat annually and if it needs recoating, do so with micro-porous stain or paint. This is how to do it:

1 Use the steps above and allow it to completely dry off

2 Rub down the existing paint or stain finish by lightly rubbing a fine grade of wet and dry silicon carbide abrasive paper.

3 Remove the dust and debris with a wet cloth

4 Again, allow plenty of time to dry

5 Apply a micro porous finish with a brush

Scratches and Chips:

If you notice a chip or a scratch on your timber, it is advisable to treat the damage immediately. Firstly you need to prepare the damaged area by removing all surface damage with a light abrasive. It’s important to follow the line of the grain and not go across it. Remove all dust with a wet cloth. Where necessary, timber filler may be required to repair the damage and leave a smooth surface. Reapply the finish to the damaged area.

Knots, Grain & Movement:

As timber is a natural product, knots and differences in grain appearance will often occur. This isn’t a fault with your windows, it’s part of the natural beauty of a timber product. Because it’s natural, there can also be a degree of natural movement in terms of expansion and contraction.
