Window Installer FAQs

How much does one double glazed window cost?
How much one double glazed window costs is based on a few factors. If you just want to buy the window to install yourself, it will cost less than if you want an installer to fit it for you. If you want to simply buy one double glazed window without installation it could cost anywhere between £100-£300. That’s for a simple casement window, but other types like sash or tilt and turn windows could cost more. It’s recommended that you get a reputable installer to fit your double glazed windows because they’ve had the relevant training and will be able to install it much more quickly. How much it will cost for them to install one double glazed window will very based on your location, the type of window, how difficult the window is to access and whether you choose standard white uPVC or a coloured or woodgrain effect. An average uPVC casement window might cost somewhere between £300-£400, while a dual turn window might cost between £550-£660 to install. Do you really need to replace the entire window? If it’s just the double glazing that needs replacing, for example if it’s misted up inside, this will cost much less. Most window installers or a glazier will be able to just replace the sealed unit inside, and that may cost as little as £250. It’s always best to get a range of quotes from reputable companies so you know you’ve got a great price and you’re sure you’ll get excellent service.

how does double glazing work?

One of the essential factors that makes a home truly a home is the convenience and comfort it provides us. As a result, we usually have a long to do list comprising things that come together to make sure our home is comfortable with ambient temperature at the very top of the scale of preference. After all, no matter how greatly designed your furniture and home decor is, it probably would amount for nothing if the temperature is either too hot or too cold. Some of the most common ways we incorporate to make the temperature a lot more conducive and warm during the winter months is by installing air conditioning system or through top notch insulation materials, but the fact still remains that a lot of heat would escape through the doors and windows. And that’s exactly the use of double glazing. So how exactly does double glazing work?

Double glazing basically works by preventing the escape of air and trapping it between two panes of glass. It’s the trapped air which serves as an insulation barrier which delivers 3 major functions. First and foremost, it stops the escape of heat through the window as the barrier created insulates the room from varying air temperatures at both sides of the glazing unit. The second major function is the double glazing works to keep down noise pollution coming from outside. While the third major function of double glazing I the fact that it helps minimize condensation which usually occurs on the single glazed windows’ inside as the cold outside air works to cool the warm air inside the house. When you install a double glazing window, the insulation barrier generated will work to stop the air temperature transmission which ultimately helps prevent the occurrence of condensation.

How much is it to repair the glass in a window?
Accidents happen, and sometimes windows get broken. And that will lead to you wanting to replace just the glass in your window, rather than the whole frame. Also, as windows get older they can mist up on the inside, which means that the unit has ‘blown’ - so you’ll also need to replace the glass. But how much is it to replace the glass in a window? Luckily, if the frame of your window is in good condition, there’s no need to replace it, and this will reduce the cost. For an installer to fit a new pane of glass in a single glazed window, the average cost is £100, while a replacement double glazed sealed unit will cost an average of £110. Of course, as this is an average, if your window is very large you may spend more, and if your window is very small the price may be less. That's why it’s important to get a range of quotes so you can compare costs and get the best price. If you’re good at DIY, you may feel confident enough to have a go at replacing the glass in your window yourself. In that case, the cost of sealed unit and any other materials you need will cost an average of £57. It’s a significant saving, and if you think you can do it, then give it a try. However, if you’re in any way unsure, it’s best to leave it to the professionals. A window installer will be able to replace the glass in your window in less than an hour. Even though it costs more for a professional to do it, if you get it wrong and have to start over it will cost you more in the long run.
how to tile a porch roof?

Tiling a porch roof is a very important but laborious and difficult task. A project of this magnitude will require a large investment in planning and preparation way before the actual installation process takes place. It can be a brand new porch roofing tile or a replacement of the existing one, either way it’s crucial to get the right technique. If you lack proper training or experience in this field, we’d recommend you hire the services of a reliable professional probably within your local area to guarantee the best results and to save yourself some time and money. This guide will give you a good insight into the porch roof tiling process. Let’s have a look!

• With the crown looking upwards, put the first tile on the batten and centre the tile from side to side.

• Hammer a 10d nail at the base of the tile and into the batten (make sure not to overdrive the nail).

• To provide a much needed support, apply a little mortar under the first tile.

• Identify the inner end of the first tile and place another tile on top. Take a measurement from the outer end and adjust the end of the second tile to fit.

• Just like you’ve done with the first tile, nail the second tile into the batten.

• Position two tiles at the both ends of the ridge and proceed with the installation just as you’ve done with the previous tiles.

• Take a measurement of the distance across the ridge from the first tile’s outer end. Once done, you can then calculate the number of tiles required by subtracting 16 inches from your measurement and divide the answer by 8.

• Beginning at the second tile on one end of the ridge, install the half the number of ridge tiles towards the centre of the ridge. Now install the remaining tiles working from the opposite end to the ridge’s centre. At the centre of ridge should be a key tile with mortar.

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.

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.

• Life Span

• 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.
