Window Installer FAQs

Are A-rated windows worthwhile?

On the grand scale of things there isn’t a huge difference between B-rated windows and A-rated windows. Consumer watchdog Which? have calculated an extra 6.5% would be saved on energy bills with A rather than B rated panes. Be aware that A rated windows are slightly more expensive, however.

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.

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.

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 long does double glazing last?

Just like every other thing in your house, your double glazed windows have an expected lifespan attached to it as it gradually becomes less functional and less efficient over time. Although there are actually top quality windows which are able to last a very long time, but the fact still remains that nothing can stand the test of time or last forever. Even the best quality double glazed windows will eventually need to be replaced at some point. So exactly how long do double glazing windows last before need a replacement?

To make it brief, most double glazing window units are typically expected to last an average of 20 years. This number of years can, however, vary within the range of 10 to 35 years based on the several factors such as the type, quality of materials as well as installation and where the windows are located.

The reason for the depreciation in double glazing windows is, over time, the windows may be subjected to some wear, tear as well as all kinds of minor damages which includes gas filled insulated glazing unit slowly and gradually leaking. According to the Centre for Sustainable Energy, the evaporation of 25 percent of gas will ultimately minimize the windows’ thermal performance. And when this occurs, fitting a secondary glazing measure or replacing the windows should be put into consideration.

Another factor leading to the gradual depreciation in double glazing windows over time has to do with condensation. When the window collects between the layers of glass due to the failure of the seal of the perimeter and the saturation of the desiccant, can only be solved by IGU replacement.

And finally, the ravages of time also has a way of taking its toll on double glazing windows. This can happen in so many ways such that the window becomes a lot less efficient and later needing to be replaced.

what is a window sash?

Windows, being a very crucial feature in every home, are one of the things you simply can’t afford to ignore in your home. Having a good understanding and solid knowledge of your windows’ components like the window sash will help you stay up to date with them and able to identify any minor mishaps early on before it leads to a much bigger problem. So what exactly is a window sash?

Well without much fuss, a window sash is simply that part of your windows that’s able to open and close. And there could as well be more than one window sash that’s operable depending on your window’s type. Window sash usually possess a very basic design as well as structure. What’s more? This section of a window happens to be a frame that’s designed in such a way to make for easy placement inside the whole window casement. You’ll discover inside the sash frame, the window glass alongside any framework possessed by your window which includes grids.

As a result, it’s very important to keep your window sashes in a great working condition as failure to do so will make opening and closing your windows a really difficult task.

How long do double glazed sealed units last?
When it comes to how long double glazed sealed units (the glass inside the window) last, a lot of it is down to the quality of the glass and the environment that your windows sit in. It’s not uncommon for your window frames themselves (especially if they are uPVC) to last longer than your sealed units. Sealed units are called that because they’re two panes of glass sealed together with an air gap in between. They use what’s called a ‘perimeter seal’ to protect the air gap between the panes, and is usually made of butyl mastic which retains a desiccant within a perforated metallic spacer bar. The desiccant’s job is to absorb any moisture which finds its way into the air gap to stop your window from misting up on the inside. When a sealed unit fails, or is ‘blown’, it’s usually because moisture builds up around the seal and causes it to fail. Sealed units won’t last forever, so you will eventually end up with condensation inside the panes of your double glazing, but in an ideal environment your double glazed sealed units could last up to 30 years, with some manufacturers claiming as long as 40 years. But they do require a bit of maintenance and the position of your windows will also make a difference as to how long they last. There are a few things that determine how long a sealed unit will last:
  • Climate - If your window faces south, it will be subject to direct sunlight for a lot of the day. This tends to cause the sealed unit to fail more quickly – a south-facing window may last between 10-25 years. This is because the spacer bars will twist as the temperature rises and causes the adhesive holding them together to eventually fail.
  • Moisture - Windows in kitchens and bathrooms tend to fail more quickly because they come into contact with moisture more often. For example, if water gets on your windowsill when you shower, the seal around the glass will come loose more quickly if it’s constantly wet.
When you replace the sealed units in your windows or get completely new double glazing, make sure you choose an installer that uses quality products and will take all the steps to ensure that your sealed units are kept away from moisture as much as possible.
How does Aluminium double glazing work?

Double glazing is made up of two layers of glass, with a layer of argon gas in between. This type of glass can be used in Aluminium windows. The gas is a poor insulator, helping heat to stay in your home and making your windows more efficient. As well as trapping the argon gas, the second layer of glass reduces the amount of noise that enters your property, and helps to make your windows stronger and more secure.
