Window Installer FAQs

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.

How to measure the glass for a window replacement?
If the glass in your window has been damaged, you might only need to replace that rather than your whole window frame. Common reasons for needing to replace the glass in your window include:
  • The glass has smashed from an impact such as a stone hitting it from a lawnmower
  • You have been broken into and suspects used the window to gain entry
  • The glass has blown (lost its airtightness) from constant water build-up around the seals, which is common in bathrooms
  • Extreme weather or pressure changes have caused a crack
If your frames are still intact and there’s nothing wrong with your window’s locks or trims, there’s no reason why you can’t just replace the sealed unit in your window. To help with the quotation process, a window installer may ask you to measure the glass for your window replacement. It’s pretty simple to just measure the sealed unit inside your window. There are just 3 steps you need to take:
  1. Including the beading (the plastic and rubber seals around the windows that can be removed), measure the width of the window frame.
  2. Do the same for the height of the window, making sure you include the beading.
  3. Then, take 10mm off each measurement, and you have the approximate size of your glass.
A reputable window installer will still make their own measurements before confirming the size of the glass in your window and going ahead and ordering the replacement. Make sure you get a range of quotes from local and national installers so you can compare the price and their quotation process.
How to fix a cracked glass window?
You can end up with a cracked glass window in a few ways. The most common one is when a rogue stone in the lawnmower hits the window or someone’s cricket or tennis game goes wrong and you end up with a ball through the window. Youi often end up with a ‘bullseye’ type crack that expands out from the point of impact. You can also get pressure and stress cracks from intense fluctuations in pressure and temperature. Unfortunately, there’s no way you can permanently fix cracked windows without replacing the entire sealed unit. An installer can replace a cracked glass window in less than an hour simply by taking out the sealed unit (the two panes of glass in double glazed windows) and replacing it with a new one. It costs an average of £110, but you could try to do it yourself for around £55. But what if you can’t get an installer to fix your window straight away? There is a DIY method you could try. As a temporary fix for your glass window, you can use a solvent-based adhesive like epoxy which will keep the glass intact and prevent further damage. You’ll also need:
  • Washing up liquid
  • Glass cleaner
  • A lint-free cloth or rag
  • A putty knife
  • A paper plate
  • Acetone
First, you’ll want to clean the glass using the washing up liquid and a damp cloth to remove any dust or oils. Leave it for a few minutes to dry, then create a mixture of epoxy by combining the hardener and the resin and stirring it on a paper plate. Using the putty knife, spread the mixture on the cracks, making sure you press gently to fill them. Leave it for at least 5 minutes to dry, then get rid of any excess by using some acetone on a dry cloth. Clean the window using some glass cleaner and another dry cloth, and you should have a temporary fix!
What happens if I have problems with my new windows?

Ultimately the double glazing company you use is responsible for the quality of work and to ensure your windows are of an excellent standard. This is why it’s important to get a warranty and use a Fensa registered installer. If problems emerge within a couple of years then it’s likely the installation was of a poor standard.Contact the double glazing company and have the issue repaired or new windows replaced. This doesn’t matter if you received a discount of free windows as part of the deal. As long as you entered into a contract the company is obliged to restore the windows.

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.

Should I use a Fensa registered installer?

Using a Fensa registered installer isn’t compulsory but it helps to protect you from cowboys and rogue traders. It will also make life a whole lot easier in regards to Building Regulations. Replacement windows must meet a certain energy efficiency rating and once fitted you need a certificate to show your installation complies. By using a Fensa registered company they’ll issue this certificate, otherwise you’ll need the council to look at the new windows.

how deep do footings need to be for a porch?

No matter how big or small a building is, it can only be as good as it’s foundation - and that’s a fact! It all starts from the footing and when it isn’t deep enough, unlike badly installed gutters or gapped hardwood flooring, can make the whole building collapse to the ground. Just like any code recommendations, the depth of the footings of your porch is a parameter that must be complied with and adjusted to suit your local code requirements.

As a rule of thumb, you should always dig below the frost line when excavating your footings. At this depth level, the moisture present in the soil will be frozen. Ultimately, this will help the ground to act as a barrier to insulate the soil below the footing from freezing during the cold months. As a result, in regions where the weather is almost always very cold the depth of your footings is expected to be at least 48 inches. But in areas featuring a warm climate, you may be allowed to install your footings on grade.

In addition, it’s compulsory that your footings must be installed at a minimum depth of 12 inches below unsettled soil. However, if you’re constructing the structure into a steep hill’s side or by the side of a retaining wall, it’s required that you maintain the least distance to grade both vertically and laterally. In the event whereby you need to achieve a good lateral barrier, you’ll need to have your foundation dug a lot deeper compared to if it’s on a flat surface. For a more accurate and updated information, you can consult your local building inspection department to get familiar with the requirements in your area.

So if you’ve decided to lay your hands on a double glazed window, you’d probably also like to know how much it’s going to cost. Well, providing a simple and accurate answer to the question of double glazing window cost is almost impossible as there are so many factors that influences the price including the materials and style.

Several suppliers usually provide the list of their double glazing windows on their websites, however these prices are only for basic off the shelf window and most often without the installation cost.
