Window Installer FAQs

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.

Why are double glazed windows better than single glazed?

Double glazed windows are better than single glazed generally because they are more energy efficient. The clue’s in the name – double glazed windows have two panes of glass while single glazed windows only have one. In double glazed windows, there is a space between the two glass panes. This space is filled with inert gas or a tight vacuum, which helps to provide an extra level of insulation. That means that heat won’t escape your home easily, nor will it creep in, so you can keep your home at a more comfortable temperature.

The extra pane of glass also helps to increase your home’s security. Single glazing is pretty easy to smash through, whereas it will take much more effort to smash double glazing and will create more noise, so burglars might be put off.

Another reason why double glazed windows are better than single glazed ones is that they help to reduce noise. Of course, if you live by a busy road you’ll still hear some traffic noise, but it can be significantly reduced buy double glazing. In the same way that the inert gas in the middle of the two panes keeps heat in and the cold out, it also helps keep noise out.

With double glazing, you’ll also notice much less condensation. With single glazing, it’s common to see condensation on the inside of the windows, especially when the heating is on. This is because the outside of the window is cold, but the inside is warm. With double glazing, the insulation between the two panes stops there being such a difference in temperature between the inside and outside of the window.

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.

Will double glazing increase my property’s value?

These days, buyers expect homes to have double glazing. People recognise the benefits of installing double glazing, so if you don’t have it installed you should consider it. You’ll increase your property’s value and give it a better chance of selling faster, since single glazed properties are also more likely to have problems with damp and mould which could put buyers off.

What is the Window Energy Rating (WER)?

The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.

Do I need to stay at home while my windows are being replaced?

Most installers will not need you to be at home while they are fitting your windows. It is a good idea to be present though, just in case they have any questions for you and perhaps for your own peace of mind. If you cannot be there, you will need to arrange access to the property and/or agree securing the property at the end of the day.

How to fit aluminium double glazed window?

Whether you’re hiring a professional to replace your double glazing or are considering DIY, it’s a good idea to know how to fit a double glazed window.

You need to start by assembling your window. Fit any handles and cut the outer sill to size by measuring the outer wall depth. Then, screw the outer sill to the window frame and attach the frame fixers. Screw the ventilation grilles onto the inside of the frame and fix the vents on.

Next, you need put the window into place, using spacers to wedge it in. Use a spirit level to check it’s level horizontally and vertically, adding extra spacers if needed. Then, fix the frame into place at each fixing point using a drill, wall plugs and screws. Measure and cut the interior sill, and check that it’s level, adding spacers if needed. Then fix it using screws, masonry nails or adhesive.

Finally, fill in any wide gaps with foam filler and small gaps with sealant. You can get interior and exterior trims to cover these up, making your window look neat and professional.

Are coloured double glazing windows more expensive than white ones?

Coloured double glazing windows are more expensive than white ones, in general. uPVC is the cheapest material to use for double glazing, and white is the standard colour. But there are endless possibilities in terms of colours you can have, and they do come at additional cost.

Some people choose to have coloured double glazing that matches or opposes the colour of the exterior of their house. Another popular option is a woodgrain effect, which from a distance looks just like more expensive timber windows. The best thing about a wood effect is that you can have the stylish look of wooden windows without the maintenance, and they should last longer.

While coloured double glazing is more expensive than white ones, it doesn’t have to break the bank. The best thing to do is get in touch with a range of window companies and ask them to come round to give you a quote. They should be able to offer you brochures or links to websites of different brands of windows that offer coloured frames. From there, you can decide on the installers you liked most and the brand you preferred.

It’s worth bearing in mind that it’s not always best to go with the cheapest coloured windows. While there lots of good, inexpensive options out there, sometimes very cheap windows won’t be good quality and may not last as long as other slightly more expensive brands. Speak to your installer about guarantees that may come with the windows and how long they would expect them to last before making your final decision.
