A casement window is the most common and traditional choice of homeowners in the UK, due to its versatile nature. It is attached to the frame using hinges at the sides allowing them to be opened with ease and help with the ventilation as well.

Composite doors require numerous different materials for its manufacturing, some of those have been mentioned below:

1. Internal insulation
2. Timber core
3. Glass reinforced Polyester skins

Upon combining the materials under high pressure conditions, we get a door that is sturdy, more durable, and more secure than any other type of door.

The major difference between composite doors and uPVC doors is the material used for manufacturing. Composite doors are manufactured using a variety of materials whereas, uPVC doors are mainly plastic. Henceforth, composite doors maybe on the expensive end but they are more robust against weathering, provide effective security and heat retention. In addition to this their long-lasting durability is what attracts the population at large.

A composite door can last up to 30 years and are low maintenance as well. Thus, the owner doesn’t have to worry much about repairing or replacing them.

Yes, of course! We have observed in our customers the desire to replace their old patio doors with a set of period-looking French doors for a more traditional look. French doors are more slender type, making the door opening bigger as two doors are to be placed now in the space where you may previously had only one. Thus, looking great in terms of space perception.

Double glazing is a concept that involves use of two panes of glass separated by a layer of argon gas to ensure your home remains energy efficient. The gas in use is a poor heat conductor as a result it keeps warm air from escaping. The second pane of glass acts as a barrier to noise.

As a firm we understand that the needs of every house could be different and therefore have set no limits to the sizes of doors we make. An expert door designer from our team shall come and survey your property to identify the size of doors you will be needing thus, ensuring you got the door that fits you right.

The quote for a door can be affected by more than one factors, some of these factors have been mentioned below:

1. style and type of door
2. the material
3. extras (Ex: decorative glass)

The above stated can alter the price of your new door.

Depending on your front porch plans you may or may not require planning permission. If the front porch is less than 3m² in floor area and is not within 2 metres of any boundary which fronts the highway, you do not require a planning permission. However, if the above stated conditions are not satisfied you shall require a planning permission. Although need not worry we will help you all the way with the design and planning requirements that you may need.

One’s property value definitely increases upon the fitting of new windows because they improve the home insulation as well as heightens its appearance – turning the house into a potential buy.

The two doors differ mainly based on design of operation. Traditionally French doors open outwards exposing full width of the opening on the other hand, Patio doors slide sideways.
Bi Fold Doors very smartly fold inside or out on themselves, with each section folding in a concertina effect. If fitted on runners they can seamlessly fold and slide at the same time, leaving you with much more space compared to the traditional patio doors, helping to bring the outside garden and surroundings into your home.

Secured by Design (SBD) is the official police security initiative that works to improve security of buildings and their immediate surroundings with the aim to provide safe environment to live in.

SBD’s a product-based accreditation scheme. It provides a recognised standard for all security products that can deter and help reduce crime. This includes:

1. domestic windows and doors
2. components (such as locks, hinges etc.)

U-Value indicates how well your window is at retaining the internal heat within your home and preventing it from escaping to the outside. It is measured in Watts per square metre, or W/m2 K, lower the U-Value number implies better the heat retention of a window. All new or replacement windows require a minimum U Value of 1.6 W/m2 K. 

Most experts have agreed that aluminium is the preferred material over uPVC. Aluminium is inherently strong and requires no extra reinforcing of its frames as a result allowing aluminium frames to be made slimmer in profile compared to uPVC windows. Thus, making them look neater and allowing more light into the house.

UPVC windows have a high coefficient of thermal expansion making them prone to twisting and warping, especially when exposed to a lot of sun. Meaning, they can start to let in drafts and rainwater after 10 – 15 years. Aluminium on the other hand is not as sensitive to higher temperatures and UV radiation thus, can easily last up to 40 years and beyond.

UPVC windows can be recycled at the end of their useful life, but it is a difficult and expensive procedure due to the presence of polymers and reinforcing material. However, aluminium frames can be recycled repeatedly with virtually no deterioration in quality.

A casement refers to the moving part of a window i.e., the bit that opens and closes. The flush casement window that is at its peak features casements that sit completely level with the frame for a neater, more understated look. The difference is observable when comparing the two windows side by side

Glazing work refers to the installation, repair, or maintenance of glass or glazing systems in buildings. This can include a wide range of tasks related to glass, such as installing windows, doors, skylights, curtain walls, or glass partitions.

The benefits of glazing windows include improved energy efficiency, noise reduction, enhanced security, UV protection, reduced condensation, and improved aesthetics.

Yes, window replacement is often worth the cost due to increased energy efficiency, improved aesthetics, enhanced comfort, and potential long-term savings on energy bills.

The cost of new windows can vary widely depending on factors such as size, material, style, and installation requirements, but generally, prices can range from a few hundred to several thousand dollars per window.

Double glazing reduces noise by creating a barrier between the interior and exterior environments, with two panes of glass and an insulating layer of air or gas between them, which helps to absorb and dampen sound vibrations.

Our Wide Range of window and door Colours are white, black, anthracite grey and RAL Colors.

To repair a double glazed window, identify and replace damaged seals, fix any hardware issues such as hinges or locks, and address condensation by sealing any gaps or leaks in the window frame.

Yes, secondary glazing can work on larger windows, but it may require additional support and customization to ensure proper installation and effectiveness.
