Five signs you need to replace your uPVC windows

UPVC windows are one of the most cost-efficient, high-quality and easy to maintain windows available. However, there comes a time when your uPVC windows need replacing. Therefore, it’s important you’re aware of the warning signs that could be putting your home, your health, and your bank balance at risk.

So, to help you out, here are 5 signs you need to replace your uPVC windows.

  1. Your home is draughty


One of the signs that your windows need replacing is the presence of draughts in your home. Often, people tend to notice draughts in their home during the winter. Not only are draughts uncomfortable and cold, they are also a common sign of insulation failure.

Did you know that having draughty windows can cause your energy bills to be around 10-25% higher? Draughts can be an expensive problem! Therefore, to reduce your outgoings, it is worth considering replacing your windows with energy-efficient alternatives. Things like double-glazing in new windows can have a significant impact!

  1. Curtains, carpets, and furniture materials are faded


Have you started noticing that the materials in your home are starting to fade in colour? If the faded materials are close to the window, it’s likely the culprit is single paned glass or old windows that no longer keep out the UV rays. If you think the materials in your home are becoming faded or the plant leaves are yellowing, it may be worth considering a uPVC window replacement.

If you replace your windows with quality double glazing and UV protection panes, you can increase the natural light in your home safely and effectively while also reducing sun glare.

  1. Problems with condensation


One of the most telling signs there are problems with your current windows is condensation. Despite the fact your windows may be double-glazed, there is still the possibility of humidity and moisture infiltration as the windows age. Although there are steps you can take to reduce condensation in your home, the best solution is to replace your windows.

Problems with condensation are often a sign your windows are experiencing seal failure, which happens to old windows over time. Experiencing condensation is another important sign that you may need to replace the glass of your windows.

  1. You’re experiencing noise pollution


Have you found that you’re experiencing a lot of noise in your home, even when all the windows and doors are closed? Have you ever heard of something called noise pollution? Experiencing constant noise from outside, whether from people, weather or traffic, is considered noise pollution and can lead to severe stress and frustration for many family members.

Although we don’t often have control over the noise happening outside, there are ways it can be kept out of our homes. One of the best ways you can do this is by replacing your windows with high-quality, double-glazed uPVC replacements. This should keep your home free from noise, protected, and comfortable.

  1. You don’t have double glazing


An absolute must for every property in the UK is double glazing. There are so many benefits to double-glazed windows, including energy-efficiency, security, durability, and reduced noise pollution. However, if your home was built before 1970 it might have the original single pane windows in place. Single pane windows can put the security of your home at risk, they let in noise, and they are extremely inefficient, raising your bills exponentially.

If you don’t have double-glazed windows you have been seriously missing out. Prioritise replacing all your single glazed window panes with double glazing to help make your home more comfortable and even raise its market value!

Tired of paying for window cleaning?

What’s the worst thing about cleaning upstairs windows?

For some people, it’s going up ladders; for others, it’s paying someone else to go up ladders.

We have a solution that will make your life easier and safer – tilt and turn windows. With easy access to the outside glass from inside the property, tilt and turn windows make a practical and stylish alternative to casement windows. The design also allows the window to be tilted open for ventilation. See more on our website.

Marquand Window


If only Henry G. Marquand would have come to Admiral, he could’ve had the real thing. As it was, he had to make do with a sketch.

This stained glass trompe l’oeil (deceives the eye) piece is now exhibited in the Museum of the City of New York.

Conservatory roofs – G values and U values explained

admiral-vic_roof_bannerThe G-value, expressed either as a percentage or as a decimal fraction of 1, shows how much of the sun’s radiant energy is allowed to pass into the room. The lower the G-value, the less the conservatory will overheat during the summer months. Two 4mm sheets of basic clear glass might have a G-value of 0.75 (75%) whereas replacing the outer sheet with Pilkington Perfect Day Super-Blue brings the G-value down to 0.4 (40%).

The U-value is the overall heat-transfer coefficient; a numerical expression of the calculation (W/m2 K) Watts per square meter times temperature (Kelvin being the scale of absolute temperature). Simply put for our purpose, it is the measure of how well a material is able to retain heat. The lower the U-value, the warmer the conservatory will be in the winter months. The two 4mm sheets of clear glass in the previous example will give a U-value of 2.8, whereas a top-sheet of Pilkington Perfect Day Super Blue brings this down to a U-value of 1.2. These values are logarithmic, e.g. a U-value of 1.2 gives much more than double the heat-retention of U value 2.4.

Polycarbonate roofs versus glass roofs – which option gives better insulation?

A roof panelled with 32mm seven-wall tinted polycarbonate will give U-value of 1.4:- a much better performance than is achieved by two sheets of clear glass but not as good as the U value of 1.2 that is achieved by the purpose-made Pilkington Super Blue roof glass – and a tinted polycarbonate roof will allow in considerably less light than will a tinted glass roof.

In many cases, we are able to replace an existing polycarbonate roof with a solar control glass roof – which is much less expensive than replacing the whole conservatory! We offer a free no-obligation visit to your property, where we will assess and discuss with you the potential to replace your existing conservatory roof.

Clear Shield glass treatment

Clear Shield homepage_montage

We are delighted to announce that Admiral Windows have now been appointed as a certified installer of the Clear Shield Eco-System – a glass treatment that has been specifically developed to protect and maintain glass surfaces.

It works like the non-stick coatings that are applied to cookware. Clear Shield forms a strong multi molecular bond on the surface of the glass, preventing contaminants from bonding to the glass surface. In this way, glass can be kept looking like new – Clear Shield coatings are easy to clean using normal non-abrasive cleaning methods. This unique polymeric resin can provide up to 10 years protection on sloping surfaces before it needs re-coating, or up to 15 years protection on vertical surfaces.

  • Keeps glass looking like new
  • Resists staining and discolouration
  • Easier cleaning

Guidelines on durability and cleaning can be found here (pdf – link opens in new tab / window).

Selling your house? Eight tips to improve the appeal of an older conservatory

If you are about to move house, you will want to maximise your home’s appeal to potential buyers. How will you highlight an older conservatory’s value as a liveable extension? We’ll begin with the cheap stuff.

Inevitably, when I say ‘cheap’, I mean those little jobs that you’ve been putting off …

1/ De-clutter. A conservatory is not a storage shed. Remove bikes, toys, lawnmowers, gardening shears, old mattresses, the broken radiogram that’s sure to be worth a fortune once it’s been ‘fixed up’, etc. etc.

2/ Now that the lawnmower’s out, cut the grass in the garden and do the weeding. The view from the conservatory should be one that lets your potential buyers imagine themselves spending idyllic evenings looking out onto a dreamy garden paradise, not compiling ‘to do’ lists.

3/ This won’t work nearly as well if the windows aren’t clean – so clean them! This will also ensure that it will rain very soon, so the lawn will look extra lush. Even if you do have to clean the windows all over again.

4/ While you’re cleaning the windows, look out for any misted up double-glazed units. Misting between the panes means that the insulation has broken down within the sealed unit. Call our repairs service – we can help.

5/ Repaint any plastered walls and fill any damaged areas of plasterwork. In small conservatories, light colours give a sense of greater space.

6/ Furnish the conservatory to emphasise this as a place of tranquillity – somewhere to escape to after a hard day. Fancy some new chairs or a new sofa in the lounge? Some of the ‘lived in’ ones might work well inside the conservatory.

7/ If the conservatory has a very old polycarbonate roof, the panels may look unsightly by now. Ask us about replacing the polycarbonate sheets or upgrading the polycarbonate panelled roof to a self-cleaning glass roof. This latter option will insulate the space better and will transform the look and feel of the conservatory.

8/ Attend to any relevant items above before the estate agent comes around to take the pictures. Estate agents are notoriously rubbish at taking photographs and, however much you pay them, they’re not going to spend hours in Photoshop deleting piles of washing.


When I’m cleaning windows …

Tips for window cleaning

1/ Do it on a cloudy day. Direct sunlight will cause the window to dry too quickly, resulting in streaks.

2/ Use washing-up liquid diluted in warm water, and apply to the window using a large sponge. Rinse the sponge regularly using only clean water.

3/ Starting at the top of the pane and working downwards, use a squeegee to wipe off the excess soapy water. Wipe the squeegee blade regularly during this process.

4/ Use a microfiber cloth or a chamois to remove the last of the water from the pane. Again, start at the top of the pane and work down. For this step, some people swear by the old coach driver’s trick of using scrunched-up newspaper instead of a chamois or a cloth. Extra sparkle is given by the printer’s ink – but do be careful not to let the newsprint touch the u-PVC frames, as this can cause staining.

Cleaning windows

Questions and answers

Q. What about cleaning the u-PVC frames?

A. u-PVC frames should be washed using a weak solution of washing-up liquid in water. On white frames, specialised non-abrasive liquid PVCu cleaners can be used on stubborn stains. Do not use any cleaning fluid on wood-grain finished window frames – it should be soapy water only on these.

Q. How often should I clean my windows?

A. About every 6 months should do it – unless you live close to a busy road, in which case more frequent cleaning will be necessary.

Q. What about the self-cleaning glass on my conservatory roof?

A. Ideally, glass such as Pilkington Activ should be left to self-clean via the actions of rainwater and sunlight. During long dry spells, a hosing down with clean soft water will accelerate the self-cleaning process. As a last resort only, a mild solution of washing-up liquid can be applied and then rinsed off, but be careful not to scratch the external coating.

Q. My upstairs windows are hard to clean outside, and I don’t like going up ladders or paying for professional window cleaners. What can I do?

A. Consider installing tilt and turn windows – the outer panes can then be cleaned safely from inside.
