How to care for timber windows


Date: 02/08/2017

All our timber frames are made from specially selected, seasoned wood. The wood has natural properties that will help it withstand the elements but to make it last even longer we apply a 'colour harmonising' finish in the factory, which contains a preservative. We then apply a micro-porous protective stain or paint finish.

General Cleaning – carry out regularly at least twice a year

  • For general cleaning use a soft cloth and water with soap or washing-up liquid
  • To remove grease marks, use washing-up liquid with little or no water then rinse with clean water
  • Do not use glass cleaner on frames
  • Do not use kitchen / bathroom cleaners

Wood is not indestructible. Maintenance of the coated finish is important, not only to keep the window or door looking good, but with the correct maintenance your products should last even longer than their guarantees.

To Recoat

It is recommended that the surface coating is inspected annually and if required you should re-coat the wood with micro-porous stain or paint.

Here’s how:

  • Clean the window or door as above and let it dry completely
  • Use a fine grade of wet and dry silicon carbide abrasive paper to lightly rub down the existing paint or stain finish (do not try to rub through the existing coat. This exercise is intended only to remove any grease and dirt and provide a smooth surface)
  • Remove all dust and debris with a wet cloth, taking care to avoid inhalation of the dust
  • Allow to dry thoroughly
  • Apply the micro-porous finish with a brush, taking care not to overload the brush or get the finish on the seals or gaskets
  • Only use micro-porous paint or stain. Avoid non-micro-porous finishes such as yacht varnish as they need stripping and renewing more often. And you should follow the instructions on the container carefully.      

Scratches and Chips

  • Damaged timber should be re-painted or re-stained immediately
  • First, prepare the damaged area by removing all surface damage with a light abrasive following the line of the grain
  • Remove all dust and debris with a wet cloth, taking care to avoid inhaling the dust
  • Where necessary, a timber filler may be used to repair the damage and provide a smooth surface for reapplying the finish
  • Re-apply the finish to the damaged area as described above

Failure to treat scratches and chips will invalidate the product guarantee.

Knots, Grain and Movement

Wood is a natural product and features such as knots and differences in grain appearance do occur. This is not a fault but part of the natural beauty of our timber product. As a natural product some degree of movement in terms of expansion or contraction can be expected.
