Maintenance and Cleaning

Within our double and triple glazed units, the float glass can be easily scratched. Therefore, when undertaking routine cleaning, it is necessary to remove any jewellery and avoid contact with any metal elements of clothing items that could cause damage prior to cleaning. It is also recommended that large particles of dirt are removed prior to cleaning with household glass cleaner and soft cloth. To remove this dirt we recommend to use a simple solution of soap and water. Glass with internal georgian bar or lead work should also be cleaned in this manner. Avoid all solvent-based or abrasive cleaning products.

In glass units with external georgian bar or lead work, care must be taken to avoid dislodging the designs. When cleaning, ensure to gently clean around external elements to avoid dirt build up. Please note that lead is subject to oxidisation as a natural phenomenon and cannot be prevented.

PVCu frames should be cleaned at least every four months with a soap and water solution to prevent build up of dirt. Use a soft cloth to prevent damage or scratches. Take care around sealants to avoid deterioration or damage.

Polycarbonate roofing panels are to be cleaned in the same manner as PVCu frames. They are to be cleaned at least every four months with a gentle soap and water solution and soft cloth to prevent build up of dirt. Guttering is to be routinely cleaned of debris to allow sufficient drainage. Do not walk on conservatory roofs.

All of our PVCu windows and doors comprise of a full drainage system to ensure that any water ingress can escape. To ensure that this remains functioning, it is necessary to check drainage holes for blockages by removing any dirt.


Stainless steel hardware and glazing trims must be routinely cleaned to avoid ‘tea-staining’. Tea staining is common on stainless steel components and is a result of contaminants being left on the product surface. Lack of cleaning and routine maintenance of stainless steel products is not covered under guarantee.

Chrome and Gold hardware is protected with a lacquer coating when installed. By routinely cleaning the product, this will be best protected. However, the lacquer beginning to peel and tarnish over time is a natural occurance.
