Window Installer FAQs

Will double glazing stop condensation?

If you’ve got a problem with condensation and don’t have double glazing, you should find that getting new windows will help. Condensation is caused by warm air meeting a cold surface which then turns into water droplets. With two panes of glass, less heat will escape from your home and keep the window warmer, meaning when steam from the bathroom or kitchen touches your windows there should be less condensation.

What to put over a broken window?
A broken window is a nuisance and an unwanted expense, and it can often happen at the worst times, like overnight when installers aren’t available or when the weather is very bad. So you might need to put something over your broken window as a temporary measure before someone can come and replace it – but what should you use? If you’ve got a small crack, you could try using some masking tape. Cover the entire crack with the tape making sure that there is extra tape at each end of the crack. This will help to prevent the crack from growing further. However, this isn’t going to work on large impact cracks or shattered windows. For a shattered window, you need to make sure you remove all the remaining glass as the shards could easily cut someone. To make a broken window like this safe, you’ll need:
  • Thick gloves
  • A hammer
  • A broom
  • A vacuum cleaner
  • Thick-soled shoes
  • Safety goggles
  1. Put your gloves on and use the hammer to remove the rest of the glass. Make sure you hit the glass away from you.
  2. Using the broom, sweep away any loose glass from the area, making sure you do both inside and outside.
  3. Use your vacuum cleaner to remove any small pieces of glass that you might not have been able to see.
Once you’ve cleared up the mess, you’ll want to cover your broken window with plastic and tape. It’s only a temporary measure so make sure you get in touch with a professional as soon as possible. Cut some heavy-duty plastic to fit the entire window. Using duct tape, secure the plastic over the window and make sure all the sides are sealed properly. It’s best to ensure that the plastic stays taught over the frame so it doesn’t get caught by the wind. Make sure you get in touch with a glazier or window installer as soon as you can – you'll notice a draught very quickly and someone could easily come and rip the plastic off. If you’re very worried about this you might want to add a chipboard over the top to make it more secure.

Can you repair blown double glazed windows?

You can only repair blown double glazed windows in the sense that you can replace the sealed unit (the glass part of the window) instead of having to replace the entire window.

When a double glazed window is blown, it means that the seal around the window has failed and is now letting air in and out. Often the first sign that the sealed unit has blown is condensation on the inside of the window, which is annoying since there’s no way to get rid of it! When your sealed unit has blown, you’ll be losing heat out of the window, meaning you could be spending more on your energy bills.

As a temporary fix, you could see if you can buy a misting repair kit online, but the condensation will eventually occur again as the air gets in. The best thing to do is ask a window installer or glazier to replace the sealed unit for you.

It's simple to replace the glass in a window – the specialist will remove the beading around the window, remove the blown glass from your window frame and set it to one side. They will then clean up around the frame before adding spacers in, then fitting the new sealed unit into the frame. They’ll make sure it’s a snug fit before replacing the beading back around the window to secure it.

There's no reason to put off repairing a blown double glazed window since the cost is generally much less than replacing the entire thing. A sealed unit with installation costs an average of £100, whereas a completely new window will cost around £400. You’ll soon notice that it’s less draughty and will be able see out of your window once you’ve had the blown glass replaced.

do you need planning permission for a porch?

There are so many benefits that comes with building a porch in your home premises. It’s an extra space where a lot can be achieved such as drying a dripping wet dog, taking off your dirty shoes or boot and lots more. So if you’re considering to construct a porch, it’s definitely going to be a wise decision. However, before you get started, there’s a need to determine if you’ll need planning permission for a porch. It’s important to take note that planning laws are dynamic and can be updated at any point, so be sure only to use trusted sources only as your guide. If you’re the homeowner or landlord, it’s entirely your responsibility to obtain the right approval for any development project you wish to carry out within your premises.

A Porch can not be termed as an extension and neither is it a conservatory, they’re basically built to the home’s front covering the main entrance using a stone base or a brick. As a result, a porch does not need planning permission due to the fact that it’s covered by the permitted development rights if the specific guidelines for porches are complied with. Below are the instances where you WILL need planning permission for a porch.

✓ If the floor space is more than 3sqm (the wall inclusive).

✓ The highest point has a height of more than 3 metres.

✓ If the porch is situated within 2 metres of a boundary directly facing on to the road.

You may need planning permission if the house is a listed building, designated area or falls under an Article 4 Direction.

In order to build a porch without planning permission, you need to consider all the criteria stated above. You can also visit the Planning Portal website to get more detailed information before getting started.

is a porch made from uPVC?

The simple answer to this question is... they can be! Although there are many types of porch designs that are available in the market, the uPVC porch happens to be one of the most loved and cost effective. Most home and property owners prefer the installation of a uPVC porch for a number of reasons. These includes:

• Value for money

It’s no coincidence the uPVC is widely accepted across the building industry with a plethora of uses. Not only is it relatively inexpensive to manufacture, but even the recycled uPVC is now becoming more and more useful. UPVC’s main rivals are wood and aluminium, and both are way more expensive to incorporate for frame profiles. Therefore, making use of uPVC is going to make your initial costs relatively low.

• Life Span

Although the main rivals in both hardwood and aluminium can also boast a lengthy lifespan just as uPVC. However, considering the price that you can get a uPVC, the lifespan is just incredible as it can be measured in decades.

• Aesthetic Appeal

UPVC gives you a wide range of foil colours that’ll fit your home perfectly well while also enhancing it’s visual appeal. You can actually get a porch that looks exactly like it’s manufactured from timber frames. To achieve this, all you need to do would be to make use of a wood grain surface finish. This is also long lasting, strong and resistant to fade.

• Little Maintenance

This is a very common feature of uPVC that makes it even more advantageous when used in making a porch. Unlike timber or wood which swells due to absorption of water or shrinks, you’ll never need to worry about all these distortions and more with uPVC. No painting, no sanding and ultimately, low maintenance required.

And there could as well be more than one window sash that’s operable depending on your window’s type. Window sash usually possess a very basic design as well as structure. What’s more?

How much money will I save with double glazing?

It’s not just the financial gain that makes double glazing attractive though and you can also save up to 680kg of carbon emissions annually.

how to fit a double glazed window?

Did you just purchase a double glazed window and confused about how to have it installed? Fitting the window yourself can be quite easy with the help of this step by step guide. However, if you lack proper training or experience, we’d recommend you reach out to a trustworthy professional who can guarantee the best results for help. That said, now let’s take a look at the process.

• Remove the old windows by detaching the old beading and glass window safely. Then make some interval cuts using a hand saw before using a crowbar to pry it out.

• Cut the external double glazed window seal. Once done, take a measurement of the window area’s width once empty. Then transfer the measurement to the window sil to face outside and cut using a handsaw.

• Seal the window sil. Add a bead of clear silicone along both inside lip as well as the centre to seal the sil.

• Screw the double glazed window to the sil. Position the window on the top of the lipped section that was siliconed. Then pre-drill them together and screw in three places. You should make sure the screws do not go totally to the sil’s bottom.

• Install the double glazed window. After successfully screwing the double glazed window to the sil, you can now fit in the double glazing. Make use of packers to make sure it’s even in the slot.

• Screw the uPVC window to the wall. If you’re happy and satisfied with the position of the window, you can then pre-drill through the frame of the window and the brick wall. Once done, simply screw it in place using masonry screws or Spax screw as they do not require crawl plugs in bricks.

• Seal around the window. To do this, simply fill any gaps with expanding foam, wipe out the excess and seal with silicone.
