Finishing service

        The treatment of timber windows is of major importance to their life span and there is more to it than just painting after fitting. We finish sashes and frames separately without any ironmongery attached or glazing fitted. This is to ensure every surface of the window is protected behind the glass, glazing bead and ironmongery. Before we apply a finish there is a lot of preparation work. Before we even assemble the timber components to form the sashes and frames we apply teknoseal 4000 to the end grain that would be otherwise inaccessible in the join. We apply v-joint sealer (Teknoseal 4001) to the joins in the sashes and frames. Please see the picture below. It shows the joins where 'v-joint' sealer has been applied and are circled in red. This is to seal up any gaps in the joins where water could potentially get in.

We apply end grain sealer to all the exposed end grain. End grain can act as a sponge, soaking in water moisture from the air through the microporous paint finish unless end grain sealer is applied. We apply knotting solution to any knots to help stop sap from seeping through. When using opaque paints(white, red, blue etc..) we use one coat of primer and two coats of top coat. The code for this option is OF. Please click here to see the opaque colours available. If required, we could apply one coat of primer only, without the top coats; the code for this option is PO. On hardwood windows we can use translucent finishes so the natural beauty of the timber can be seen. When applying translucent finishes we use one base coat and two top coats of stain; the code for this option is TF. If required, we can apply a base coat only, without applying top coats; the code for this option is BCS. Opaque paints are longer lasting than translucents. The system of treatment we use is from a manufacturer called Teknos. They have produced a good maintenance guide.

We highly recommend our treatment service as we are trained and have experience in the manufacturers treatment system and procedure. An on site decorator will probably not know this. Correct treatment application and preparation is crucial for a long life span of timber windows.

Preserver

We also provide a preserver dip treatment; the code for this option is PD. We dip the window components into a vat of preserver before any other treatment is applied. The preserver contains anti fungus and mould agents. It isn't needed for hardwoods as they contain natural oils which self preserve and is only beneficial for use on softwoods. This preserver doesn't provide any protection from the elements; it's purpose is to provide limited protection underneath the finish. It is debatable to whether the preserver is actually needed because, as long as the finish is doing it's job correctly, the timber should remain dry which means fungus and mould would find it virtually impossible to grow.
