tips on double glazing maintenance

Double Glazing Window and Door Maintenance

Glass cleaning

  • Glass in double glazed units is easily scratched, remove jewellery prior to cleaning.
  • Most brands of window cleaner may be used with a soft cloth.  Heavy external grime can be removed with a solution of soap and water.
  • Laminated glass, or glass with Georgian bars can be cleaned in the same manner.

Leaded glass cleaning 

  • Take care when cleaning leaded lights as excessive pressure might dislodge the lead from the glass surface area.
  • The use of warm soapy water and a soft cloth, lightly applied is the suggested cleaning method.

Scratched glass

Most scratches can be removed with jewellers rouge, or rubbing compound.

UPVC / PVC-U frame cleaning

  • DO NOT use solvent-based or abrasive cleaners
  • Throughout the year, wash frames with soap and water solution to remove grime.
  • For stubborn marks, clean with a non-abrasive proprietary cleaner.
  • Do not disturb sealants.

 Conservatory & porch roof cleaners

  • DO NOTuse solvent-based or abrasive cleaners
  • Roofing, rafters and UPVC components fitted to these structures must be cleaned in a similar way to UPVC frames.
  • Clear gutters of leaves to avoid overflow of rainwater.
  • Wash roof panels with soap and water solution.

Lubrication

Lubricate all hardware with a light machine oil every 6-12 months for optimum performance.

Brass work

  • Brass work is fully protected with lacquer. 
  • Through normal wear and tear the lacquer may peel or become tarnished.
  • It is advised to protect the UPVC surfaces from chemicals.

Condensation

UPVC double glazing does not always solve underlying condensation problems.  Water vapour is continually present in the atmosphere.  In the home this natural water content is increased by normal living activities and of course breathing.

Here’s a few tips to help reduce condensation:

Ventilation

  • Provide natural ventilation by opening a window.
  • Installing a ventilator or extraction unit in problem areas of the home (kitchen and bathroom).
  • Fitting wall vents to aid air flow.

Circulation

Keep internal doors to the kitchen and bathroom areas closed to prevent moist air travelling throughout the home grille.

Security

  • Double glazed windows, doors and conservatories are specifically designed to include a variety of security features to protect your home and family against unwanted intrusion.
  • Other security precautions can be taken:
  • Close all windows before leaving the home.
  • For added security, lock all windows and keep the keys out of sight.
  • At night, lock all deadbolts for full security


Why do double glazed units mist up?

The main reason why a double glazed sealed unit can mist up (or break down as it’s referred to in the trade) is due to premature failure of the perimeter seal.  Other reasons including poor installation, severe weather conditions as well as some cleaning chemicals can have an effect on the double glazed unit over time.

The perimeter edge of the unit loses its integrity and lets in moisture.  Initially it may only be visible when the sun shines directly on it and heats the moisture within drawing it upwards and appearing as condensation.  Usually it will worsen over time.

The only simple cost effective answer is to replace the double glazed sealed units with new ones.  Not the window frames themselves, just the glass. 

Replacing one of your broken or misted sealed units or door panels is relatively easy, there’s no need to pay a windows specialist, you can DIY.  There’s plenty of useful installation advice on various websites and YouTube videos.
