Window Installer FAQs

Do I need toughened glass in my windows?

Whether you need toughened glass in your windows depends on where the windows are in your home or business. Toughened glass is sometimes referred to as tempered or safety glass, and it just means it’s stronger than the standard glass that’s usually offered with double glazed windows. So how do you know if you need it?

Toughened glass is useful in areas of your home where you might come into contact with the windows if you were to trip and fall. If you put your hands out to steady yourself on standard glass the chances are it would break into large sharp pieces with jagged edges. Of course, this means that you could seriously cut yourself if this were to happen. With toughened glass, the structure of the glass is changed so that if it breaks it shatters into lots of tiny pieces, minimising the risk to you if you were to fall on it.

You might want to use toughened glass in patio doors, low windows or frames next to doors. It just means that you will be safer if the unlikely happens and you or a family member falls through the glass. There are certain requirements through Building Regulations with windows at a certain level, but any reputable window installer should be able to go through these with you if you need to replace your windows with toughened glass. The regulations will only apply to new windows – there's no need to switch your windows to toughened glass early, but when you do come to replace them you’ll need to make sure they meet the standard.

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 much is a single window?
Sometimes accidents happen, and that leads to you needing to replace just a single window. Luckily, most window fitters are happy to replace just one window if you need to. But how much a single window costs will depend on a few factors. Firstly, do you need the entire window, including the frame, replaced, or just the sealed unit? If the frame is still in good condition, glaziers and some window installers can replace the sealed unit and this will set you back around £250. If your window frame is damaged, don’t try to get away with not replacing it. Having a broken window frame can let heat escape your home, increasing your energy bills, and you’re likely to hear more traffic noise. Plus, if the frame is broken you might have trouble closing the window properly, stopping you from keeping your home secure. So how much is a single window if you need the whole thing replaced? You should expect it to cost between £400-£550, but it could cost more or less than this depending on your location, the size of the window and how tricky it is to replace. There are other factors that will impact the cost of replacing a single window. Do you want the window to have plain, leaded or Georgian bar glass? Maybe it will be a casement window, or a bay, bow or sash? The cost will increase if you want more than one opener if it’s a large window, and if you want it to have locks. Also, the standard white uPVC frame colour will probably be included in the price, but if you want a woodgrain look or a different colour uPVC this will cost more.

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 much is a porch?

If you’ve decided to construct a porch to your property and now looking to figure out the cost required to complete the project, then you’re at the right place!

There are many factors that comes to play when determining the price of building a porch. These factors includes the size of the porch, the number of windows, the style of the roof as well as the type of the porch selected. Now let’s take a look at these factors one after the other.

• The Porch’s Size

As you would have correctly imagined, a large porch will definitely cost more money than a smaller one. A rough estimate of a porch’s cost per square metre is approximately £1,400.

• The Number Of Windows

Just like in the scenario above, the more the number of windows to be incorporated, the more money you’ll have to pay to complete your porch. A porch window will generally cost you within a range of £300 to £1,000

• The Style Of The Roof

There are two popular styles of porch’s roof which includes a tiled rood and a rubber flat roof. Generally, roof tiles are costlier than a rubber flat roof. A tiled roof would cost you between £0.80 to £1.80 per roof tile, while a rubber roofing will cost your between £70 to £90 per metre squared.

• Type Of The Porch

Another huge determinant of a porch’s price is type of material incorporated. For instance, if your preferred type is a lean-to, the price of a uPVC would be between £2,300 to £2,700. Meanwhile, a flat gable roof porch should cost within a range of £3,300 to £3,800.

Kindly note that the costs quoted in this article are only rough estimates, for a more accurate estimate you can contact a porch building professional within your local area.

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.

how much are new windows?

Are you about to replace your old windows and wondering just how much it’ll cost to have a new one fitted? If yes, then you’ve come to the right place! The question is a very straight forward one, however a direct answer can not be provided as determining window prices for a replacement project can be a very tricky challenge. With a plethora of influencing factors that can play a key role in the price of both materials and labour to be used, it could be extremely hard for a window installer to provide a cost estimate without paying you a visit beforehand.

The factors that can go a long way in determining the price of your new window includes the size of the window, frame material, style chosen, your location, rates charged by the window installer (these rates can be different from an installer to an installer, so it’ll probably be in your best interest to compare quotes to identify the most competitive price) as well as the type of glass required.

Generally, for a small flat featuring four windows, the average cost for new windows would be between the range of £2,100 to £2,300. This range provided covers the cost of double glazed uPVC casement windows as well as the installation price. In the same tone, a home with up to 8 windows will have an average cost for window replacement between the range of £4,400 to £4,600, wile also taking into account the installation price. Whereas a house comprising 10 windows could begin at an average cost of window replacement between the the range of £5,200 to £5,500, and a 15 window home will be between the range of £8,400 to £8,600. it should be noted that the aforementioned figures only include the standard number of windows with a uPVC frame and the installation cost.

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.
