Window Installer FAQs

Should I get all my windows replaced at once?

You don’t have to, especially if you’re on a budget. If you’re only replacing some, it’s a good idea to get all the windows on one side of your property replaced at the same time, so they all look the same. Be aware, obviously, huge savings could be had by having a number of windows replaced at the same time.

How to remove a aluminium double glazed window?

Removing a double glazed window can be quite labour intensive. If you decide to try it yourself, make sure you give yourself plenty of time, and wear gloves and goggles.

Begin by unscrewing all opening windows at the hinges and removing them. Then take away the beading and putty around any fixed panes and take them out too.

Once you’ve removed all the glass, use a saw to put angled cuts in the frame, and a bar and hammer to remove it in sections. You should remove the sill if you’re going to replace that too.

Finally, cut through any screws holding the frame into place with a hacksaw.

what is a porch?

A porch is a small and low structure (with a roof) located at the main entrance of a building or house. It’s typically without a window (although newer variations may come with one) and can either be screened-in or enclosed to prevent unwanted access from insects and extremes in weather. In addition, some homes may have a three-season porch or sun porch. This may be situated by the side of the house and covered by the roof overhang - they’re usually screened in to offer good access all year round.

Generally, porches serve a wide range of purposes. They include:

• Provision of an outdoor living space to relax during the summer months

• It’s an informal extension of the the living room.

• It serves as a great place for social gatherings especially in small towns.

• You can take off your dirty shoes and dry a dripping wet dog before entering into your living room.

• It can be incorporated for relaxation purposes and watching street activities.

• It can serve as a reception area for guests.

• It can also be used for outdoor storage.

Pros & Cons Of A Porch

Pros

• Due to the fact that they’re covered, porches may require little maintenance practices.

• It can go a long way to improves the curb appeal of your property.

• It protects against the extremes of the weather.

• It can be constructed using a wide range of materials.

Cons

• It does not improve the use of the property

• It can be quite expensive to install depending of the material required as well as size of the porch.

• It does not add to the value of the home unlike several other home improvement projects

• It may not be safe to be used by a child or pet.

How to replace the glass in a uPVC window?
It’s not too difficult to replace the glass in a uPVC window, so if you’re a confident DIYer you could have a go at this yourself. We’ll go through the main steps on how to replace the sealed unit in a uPVC double glazed window:
  1. Using a rubber mallet and a strong pallet knife, remove the beading around the window. You might think they’re part of the frame, but they’re actually separate on the inside of the frame and can be taken out by using pallet knife to prize them out. Start with one of the longest beads first and leave the top bead until last.
  2. Give the glass a little tap to loosen it if it doesn’t come out straight away, then the whole unit should slide out easily. Just make sure it falls towards you and not back out onto the ground below!
  3. Clear any debris that has found its way into the frame with a brush. Add spacers at the bottom of the frame – these could be pieces of plastic.
  4. Get your new sealed unit (make sure you measure the glass before you buy one so you know which size to get) and carefully take it out of the packaging. Look for the British Standard mark – that shows you the bottom of the glass.
  5. Lift the glass into the frame, starting with the bottom first, and make sure that it fits square in the frame before taking the spacers out.
  6. Use a little washing up liquid to spread along the beads to make it easier when you slide them back into the frame. If they simply push and clip back in, you can use something like a block of wood to help you push them in correctly. Put them back in reverse order to how you took them out.
And there you go! If you’re feeling confident you can have a go at replacing the glass in your uPVC window yourself. But if you’ve got any worries, leave it to a window installer who will be able to do it in less than an hour.
What if my home isn’t suitable for double glazing?

Some properties are unable to have double glazing, especially those in conservation areas or listed buildings. To counter this problem and still benefit from a warmer home and cheaper bills, secondary glazing is an option. Secondary glazing is a second pane fitted inside your original window. Secondary glazing will still save you around £105 yearly.

Can the glass in a double glazed window be replaced?
Yes, the glass in a double glazed window can be replaced. The glass in a window, or sealed unit to use its proper name, is not permanently attached to your window frames so if it gets damaged but your frames are still intact, there’s no need to replace the whole window. The glass in your double glazed window might need to be replaced due to:
  • Impact from a stone or other object smashing the glass in a ‘bullseye’ effect
  • The result of a break-in
  • Extreme weather or changes in pressure causing a crack
  • The sealed unit being ‘blown’, meaning that it’s no longer energy efficient due to air leaking out
A lot of window installers will replace the glass in your double glazing for you, but you might need to get quotes from specialist glaziers too. Glaziers deal purely with the glass in windows rather than installing entire frames. It won’t take a professional very long to replace the glass in your window. They will remove the beading from around the window with a pallet knife or chisel, leaving the top one until last to keep the sealed unit stable. Then, they simply lift out the glass carefully and will discuss with you whether the removal of the old sealed unit is included in their quote. Next, they will brush away any dust and debris that’s made its way into the frame and place spacers at the bottom. They will then lift the new glass into the frame, making sure it’s completely square. When they’re happy, they’ll remove the spacers and replace the beading back in reverse order. You’ll notice the replacement glass in your new window straight away as draughts should be eliminated and you’ll be able to see clearly again!
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.

What is uPVC?

uPVC is unplasticised polyvinyl chloride. It is a favourite amongst homeowners and manufacturers for its cheap production cost and excellent benefits. uPVC is used for window frames, conservatories and doors. In fact, uPVC can be three times cheaper than wooden frames and is also the most energy efficient option.As well as this, uPVC is now available in a range of colours other than the typically seen bright white finish. It can also be recycled, is durable and resistant to changing weather conditions.
