That’s why we’ve listed some helpful tips to get you started and keep your guarantee valid for even longer.

Looking after your uPVC

You might not need our uPVC double glazing repairs service in Cornwall after all…

Keeping your uPVC windows, door, or conservatory takes next to no time. Simply wash the product down with warm soapy water. Don’t use solvents or abrasive cleaners, which might compromise the gloss. Also take care to use a soft sponge or cloth, as opposed to an abrasive product that might scratch your uPVC.

Is there a mark you can’t get rid of? Then you’ll need to get a specialist uPVC cleaner.

If condensation is building up in your uPVC windows, get rid of any debris clogging up the drainage slots (which can be found between the top and bottom of the window and outer sill, and inside the sashes when your window is open).

By following the above process, you could delay the need for double glazing repairs in your Cornwall home and keep it looking fresh.

Maintain your glass too

Our glass is of the finest quality. But you may find a small imperfection or mark on its surface. If this happens, we’ll assess your windows in line with Glass & Glazing Federation Guidelines.

To clean glass in your windows, doors, or conservatory, use a non-smear cleaning product with a paper towel.

Make sure you spray onto the surface of the glass. The liquid must reach the corners. Next, wipe with a paper towel until the spray is gone. Afterwards, reverse the paper and continue buffing until the glass is dry. Want to achieve the best finish? Repeat the same process externally.

How to clean external glass:

  • Repeat your cleaning routine every four months
  • Use soapy warm water to remove grit and grime
  • Once finished, work the surface with a glass cleaner
  • Use a soft towel or cloth to avoid scratches 

How to clean internal glass:

  • Clean it as a habit every month
  • Complete with a glass cleaner
  • Only use paper towels or clean cloths

Hardware care

It’s important to lubricate those metal-to-metal joints without nylon bearings. This process should be repeated for all relevant uPVC double glazing. Use 3-in-1 light engineering oil and apply it to your shootbolts, locking mechanisms, hinges, friction stays, and espagnolette.

Make sure you lubricate any rollers, shootbolts, or espagnolettes that engage with locking keeps. These need to be maintained yearly and we’d recommend using lanolin, which is a light grease.

Hardware cleaning tips:

  1. Never use abrasive solvents or products that could harm your uPVC double glazing
  2. Look after your window furniture by cleaning it every four months
  3. When cleaning, clear away dust and dirt with a damp chamois
  4. Choose high-quality polishing and coatings that last longer

General cleaning tips:

  • To avoid scuffing or scratching your uPVC windows, doors, or conservatory, remove all jewellery before cleaning
  • It’s inadvisable to lean ladders against your frames, glazing or gutter. And we would never recommend walking on a bay roof. If you need to access a hard-to-reach area, hire some tower fixed scaffolding.
  • Always adapt your method to suit the area of the window you’re cleaning.


Avoid future double glazing repairs in your Cornwall home by quickly wiping your handles down with a damp cloth to remove grime and dust.


Weather seals stop cold draughts entering your home while keeping warm air inside. Should a seal become dislodged from its grooves, manoeuvre it back into position to prevent damage.

Composite doors

A popular front door choice, composite doors are robust, strong, and designed to keep you and your family safe. 

They’re easy to look after too and could delay the need for double glazing repairs on your Cornwall property. Here’s how.

Door Leaf

Simply apply a warm soapy sponge or cloth to banish grime

Door frame

Again, your trusted sponge will work wonders (stubborn stains can be removed using a specialise uPVC cleaner).

Exterior Glass

Once more, simply clean using a soapy cloth. Complete using a high-quality glass cleaner.

Leaded glass

Follow the same process outlined for exterior glass. Over time, natural oxidation will occur.


Find a clean cloth, dip it in some lukewarm water with mild detergent. After that, wipe away until a shine is achieved. For moving parts, use 3-in-1 light engineering oil.


Lubricate using a quality light engineering oil.

Cylinder locks

A Teflon-based lubricant is advisable. Avoid using oil or graphite powder.
