General Maintenance

Lubrication of the hinges

For lubrication of handles, locks and hinges, etc. use a light machine oil lubricant for moving parts and petroleum jelly if indicated on the windows/doors

Anodised Gold Finish (Not Brass)

Never use abrasive cleaning agents. Warm water and a soft cloth are sufficient.


When installed, Brass work is fully protected with lacquer. In time and through normal wear and tear, this lacquer may peel or become tarnished.

    Tips to refurbish your brass work:

  • Protect the surrounding PVCu surfaces by masking off an area around each piece of brass work.
  • Remove old lacquer with nail polish remover or paint stripper
  • Clean and polish with a suitable proprietary brass polish
  • Carefully relacquer with a good quality product

Glazing Care

Standard Sealed Units

Laminated glass or glass containing Georgian bars between the sealed units is cleaned in exactly the same manner. *Please ask for our additional document on cleaning Conservaglass.

Leaded Glass Cleaning

Extra care must be taken when cleaning leaded windows so as not to dislodge the lead from the surface of the glass. Warm soapy water applied with a soft cloth is adequate for cleaning leaded glass. PLEASE NOTE THAT EXTERNAL LEAD WILL OXIDISE. THIS IS A NATURAL PHENOMENA AND CANNOT BE AVOIDED.

Scratched Glass

Scratches can be removed with jeweller’s rouge or equivalent rubbing compound. (Please ask your installer for further advice).

General Cleaning

Roof & Side Frames

Frames PVCu doors only – to remove any stubborn blemishes use a strong, non-abrasive, proprietary cleaner such as cream cleanser.

Gutters & Box Gutters

In a conservatory the guttering is always laid in accordance with BS 63 67:1983 Code of Practice for Drainage of Roofs, therefore you will notice standing water in your gutter system. It is important that you clean the gutters regularly – be sure to use crawl boards when accessing a conservatory roof.


Advice picture



Condensation occurs when water vapour comes into contact with a cold surface such as glass and the vapour turns to water droplets. Condensation can only ever be minimalised and never completely eradicated. Newly constructed conservatories need an initial ‘drying out’ period. Many hundreds of litres of water are used during its construction, i.e. dwarf walls, concrete bases and plasterwork. In winter they will take longer to dry out.


Provide natural ventilation to help minimise condensation and maintain a comfortable interior temperature whenever possible by:

  • Opening windows/doors
  • Ensure trickle vents in the ridge are open at all times
  • Ensure all other vents are open when possible
  • Be sure to consider security when leaving open an easily accessible window or roof vent.


Heating can also assist with controlling condensation and should be marginally increased in any areas where condensation is a problem. Maintain some heat in the conservatory during cold weather and if possible, place heating appliances under windows to maintain the temperature of the inside pane of the double glazing.
