Windows and Doors

We recommend applying silicone-based products, for example, WD40, onto your window hinges at least twice a year. This will help to protect your windows from rust or corrosion. This also helps to lubricate bolts and hinges that may cause you issues.

If there has been exposure to a lot of rain, make sure an effective drainage system is available. If you are unsure of what to do with your windows, you can always get in touch with us and tell us your concerns.

Before any cleaning takes place, remove any jewellery as there is a risk that it may scratch the glazing – even if you are only cleaning the frame. When cleaning your window frame, we recommend using something soft, including a cloth, to wash your windows down with. Warm water with a small amount of washing up liquid is our recommended cleaning solution.

Cleaning the actual windows can be tricky as you don’t want to leave streaks. The easiest option would be to hire a window cleaner. If you prefer to do it yourself, there are fantastic window cleaning products to buy for all budgets. Window vacuum cleaners are great for preventing streaks.

When cleaning your windows, make sure that the gaskets remain in place. If they come apart from the frame, all you need to do is slide them back into place.

Top Tips

Do not use either an abrasive or solvent-based cleaner.

If a scratch occurs on the glass, this can be removed with a rubbing compound, or you can get in touch with us to discuss your repair further.

Over time, the mastic seal may discolour or peel. To restore this, simply carefully cover any uPVC frame completely and remove the old sealant coating with nail polish remover or paint stripper.  Please ensure that the uPVC is completely covered to protect its finish. Apply brass polish and re-coat with product of your choice. It is as easy as that!


Conservatories are a big investment for any homeowner, and there are various ways to look after them. Like with any window or door, the conservatory frames can be washed down with a damp cloth and warm soapy water.

For the glass itself, all you need is a good wiper and glass cleaner, and you are all set to go. This will ensure that your windows will be streak-free. There are a variety of glass cleaner options that will suit any budget.

Products such as WD40 is a great option for the locks and hinges that need maintenance. This is only required once a year, and then you don’t have to think about it for a while.

Guttering is a fantastic way to direct any rainwater away from your home. However, if you live near trees, you may find that they fall into your gutter. Make sure to clear the gutter to improve the drainage. You can also invest in gutter netting to prevent the leaves from going into your gutter.

Top Tips

Never use anything abrasive or solvent-based when cleaning the frames of your conservatory as this may cause damage.

Remove any jewellery, watches or fmasadditional materials on your hands to prevent scratched glass.

Invest in a sturdy ladder and make sure you have someone with you to support it when you go up.

If you notice any cracks in your conservatory, or if you have any concerns, get in touch with us straight away.



Condensation occurs when the temperature on one side of the glass is different to the other side of the window. This forms droplets of water on your windows and doors. There are many easy ways that you can reduce the risk of condensation in your home.


Simply by opening your windows, you can improve the level of ventilation in your home. This is beneficial, especially in the summer, where you can release the moist air and return your home’s temperature to a normal level.


A dehumidifier is a great way to get all the moisture out of the air when you aren’t at home. We understand that you may not want to leave your windows open when you are away, and a dehumidifier is a fantastic alternative. There are low-cost products that work wonders.


Oven and bathroom fans may make a lot of noise, but they are vital to condensation. When there is a collection of steam from cooking or the bathroom, this is a factor towards condensation. In the other rooms in your home, why not invest in a room fan?


Although curtains are a great way to add to the aesthetics of your home and give you some privacy, if placed wrongly, it can affect the condensation in your home. Curtains should be at least 150mm away from your window, to improve the air circulation.
