Premium windows at affordable prices
Available Throughout Dorchester & The Whole of Dorset
Dorchester Casement Windows
Casement windows are known for their outward opening operation. They are available in numerous configurations, crafted from high-quality materials and available thousands of colour choices to match your home.
The tight seal achieved by our casement windows guarantees exceptional weather resistance, contributing to your safety and security.
Dorchester Flush Windows
Flush windows (often called 'flush casement windows') have a clean flat profile, for a pleasing traditional look. Our flush window systems are offered in a diverse range of colours and materials to meet your needs.
Available in top-hung, side-hung and heritage styles, our flush fit windows combine modern machining processes with the discerning eye of a craftsman.
Dorchester Tilt & Turn Windows
Double glazed tilt and turn windows offer unique advantages compared to traditional casement styles. The dual action opening means the upper sash tilts inwards, or with a different handle position the whole window can open inwards from the side.
In 'tilt' position you can gently circulate air while keeping the lower section securely closed. In 'turn' position, you can completely open the window.
Dorchester Bay Windows
Bay windows and bow windows, despite their similar names, are distinct styles. Bay windows extend the floor space of your property, whereas bow windows are usually supported underneath by a 'gallows bracket' and don't generally require planning permission.
These windows are sought-after in Dorchester because they have the ability to expand living, dining and bedroom areas, flooding them with abundant natural light.
Dorchester Sash Windows
Sash windows are a classic, timeless design that is often found in Georgian or Victorian style houses around Dorchester.
Sash windows are divided into two panes - a fixed outer pane at the top and a lower inner pane that slides open vertically.
These impeccably finished double glazed windows offer a great level of adjustment to the ventilation in a property, whilst remaining flush to the walls in any position.
Dorchester Heritage Windows
The term 'heritage window' is often associated with a number of features available within a double glazing range. The most common items that qualify a window as heritage are:
- Victorian Styling
- Wood Appearance
- Mock Hinges
- Bespoke Leadwork
- Sash Vertical Opening
- Flush Fit Frames
- Georgian Split Bars
- Sculptured Frames
- Cast Iron Handles
- Conservation Approved

Materials Available for Dorchester Double Glazed Windows
Choose the right window frame material
uPVC Windows
For many homeowners in Dorchester, uPVC windows are a popular choice thanks to their affordability and reliable performance. This weather-resistant material is designed to withstand the elements with minimal upkeep – a quick wipe down with soapy water is all it takes to keep it looking its best.
uPVC is highly versatile, complementing both modern and traditional properties. While it may not have the same long-term durability as aluminium, it offers an excellent balance of value and functionality. For a cost-effective, low-maintenance solution that enhances your home’s energy efficiency and security, uPVC remains a smart option.

Aluminium Windows
Combining strength, style, and sustainability, aluminium windows are an excellent choice for homeowners in Dorchester seeking an upgrade. Their slim yet strong frames allow for larger panes of glass, maximising natural light and creating uninterrupted views of your surroundings.
Aluminium is durable and resistant to warping, meaning these windows deliver exceptional performance with minimal maintenance. As a fully recyclable material, it is a sustainable material. With customisation options – from colours and finishes to hardware styles – aluminium frames offer a sleek, contemporary aesthetic alongside outstanding security and energy efficiency.

Wooden Windows
Wooden windows were originally the traditional choice for homes across Dorchester. Wood is a natural insulator, offering excellent thermal performance thanks to its low heat conductivity. It’s also a renewable material – ideal for homeowners seeking a sustainable option.
In conservation areas or listed properties around Dorchester, timber windows are often a requirement to maintain heritage aesthetics. That said, modern uPVC and aluminium alternatives can now replicate the classic timber appearance with advanced finishes and detailing, providing a traditional look with modern benefits like reduced maintenance and improved durability.

Triple Glazing Options
Upgrade your Dorchester Double Glazing to Triple Glazing!
Triple glazing involves three panes of glass with two insulating layers of Argon gas in between. These quality windows represent a remarkable advancement in the realm of energy-efficient building technologies, offering exceptional thermal performance.
Those three layers of glass offer superior properties to double glazed windows, at just a small extra cost.
There are Many Benefits to Triple Glazed Windows
The primary advantage of triple glazed windows lies in their superior insulation properties. The additional glass pane and gas layers significantly reduce heat transfer, minimising energy loss and enhancing the overall thermal efficiency of a Dorchester home or building.
Brackenwood triple glazing also offers significant benefits when it comes to reducing condensation. The technology behind triple glazing prevents condensation build-up on windows, keeping the interior of your home drier and healthier
