Modern Windows

The cost of new windows depends on a variety of factors, such as style, materials, size and complications with installation.

We don't offer off-the-shelf stock sizes of windows as all of our products are bespoke to your needs and made-to-measure.

For these reasons, we don't offer a price list.

At Everest, we offer a full range of colours and natural woodgrain finishes across all of our window ranges.

From popular white to Chartwell green and the modern anthracite grey or black windows.

We can even produce windows that have one colour on the outside and another on the inside to match your interior/exterior.

Double glazing lasts for around 20 years but does vary depending on the quality of the window units and the quality of the installation.

Reputable double glazing manufacturers and installers will offer guarantees (at Everest, we offer a standard 10-year guarantee on all windows and lifetime guarantees against internal condensation and discolouration*).

Of course, windows can last far longer than their predicted lifetime and many houses have windows that are over thirty years old - if they've been well-maintained.

The first part of the double glazed window that is likely to fail is the seal and second to that are the hinges.

It also depends on where the windows are positioned in a property. For example, a south-facing window that gets a lot of sun and heat is more prone to discolouring or the seals drying out.

Standard glass is called ‘Low E’ and is a great all round option for energy efficiency. Low Iron glass offers high clarity and energy efficiency. Toughened glass is five times stronger than regular glass and laminated glass, contains a plastic interlayer offering better insulation and resistance against damage.

Aluminium tends to be stronger than uPVC, which means that the frame of an aluminium window can have a slimmer profile and larger glass surface compared to its uPVC equivalent.

However, aluminium conducts heat and cold and so is not as thermally efficient as uPVC which is far better at reducing temperature transfer through the frame.

At Everest, we have the experience to reduce this problem. We limit transfer by incorporating a polyamide thermal break in the frame, a warm edge space bar between the panes and fit Low-E glass as standard.

It is better to replace all windows at once. Firstly, because the aesthetic of the property looks better with uniformity. This will help the value of your property and make it more appealing to buyers.

Secondly, it is far more cost effective to replace all windows at the same time. Installers work on a basis of having fixed costs to attend a job. The more windows you have installed at once, the cheaper the cost per unit becomes.
