Pine Sash wood window
You want sash windows that look right, work well, and don’t cost a fortune. Our pine sash windows give you all three. They're made to order, built with care, and finished to suit your home — whether you’re working on a period property or a modern extension.
Pine is lightweight, smooth, and easy to paint or stain. It’s a solid choice if you want a classic sash look without the higher price of hardwoods. You still get proper joinery, traditional detailing, and modern upgrades like double glazing and smooth operation.

Meranti Sash Windows
You want sash windows that hold up over time and still look sharp. Our Meranti sash windows give you both. They’re made for London homes — especially where windows take more weather — and built to match your style, whether traditional or modern.
Meranti is a dense hardwood that resists moisture, holds paint well, and stays stable through changing seasons. You get a warm, premium finish without the maintenance headaches. We make each window to fit your space, your layout, and how you want it to look and work.
Why choose Meranti sash windows?
Built for weather – Good choice for exposed areas
Low movement – Fewer issues over time
Premium finish – Rich colour and smooth grain
Custom-made – Fits your home, not the other way around
Glazing options – Add double glazing for better insulation

Oak Sash wood windows
You want sash windows that look good and last for decades. Our oak sash windows are built for that. Oak is strong, dense, and naturally durable — perfect if you need windows that can take the wear without losing their shape or finish.
With its rich grain and classic look, oak works well in both period homes and modern builds. We make each window to fit your space, match your style, and deliver modern performance — including options like double glazing for better insulation.
Why choose oak sash windows?
Built to last – Strong, stable, and ready for long-term use
Classic finish – Rich grain adds warmth and character
Custom-made – Designed to suit your home, not standard sizes
Works with modern upgrades – Add double glazing without losing the look

These are only for ideas
Choose The System
Weight sash windows
If you're working on a period property or want a more traditional look, weight sash windows are the right choice. They use a classic weight and pulley system — hidden inside the frame — to make the sashes move smoothly and stay balanced.
This setup is often required in listed buildings or conservation areas, where keeping the original appearance matters. It also adds a level of detail and authenticity that spring systems can’t match.
Traditional mechanism – Weights and pulleys hidden inside the frame
Authentic style – Ideal for heritage homes and period renovations
Smooth operation – Balanced sashes that are easy to open and close
Conservation-ready – Meets typical planning requirements in listed areas
These windows take more work to install, but if you care about getting the details right, they’re worth it. We’ll build and fit them to match your property, with clean lines and the right finish.
Spring Sash Window
If you want the look of sash windows without the bulk of a traditional setup, spring sash windows are a solid option. They use a spring-loaded mechanism instead of weights and pulleys, so there's no need for hidden weight boxes — which means slimmer frames and more glass.
They’re easier to maintain, cost less to install, and work well in both modern homes and refurbishments where space is limited but style still matters.
Slimmer frames – No weight boxes means more light and cleaner lines
Lower cost – Quicker to install and more budget-friendly
Easy to use – Smooth, reliable operation with less maintenance
Classic look – Keeps the sash window style without the traditional setup
If you’re not restricted by heritage rules and want a more efficient solution, spring sash windows give you the look without the complexity. We’ll make them to fit your space and finish them the way you want.

Box Sash Window
If you're restoring a period home or working in a conservation area, box sash windows are the right choice. These are traditional sash windows that use a weight and pulley system, with the counterweights hidden inside a full box frame. That’s what gives them their name — and their smooth, balanced movement.
Box sash windows are typical of Georgian and Victorian homes. They’re often required for listed buildings, where keeping the original look is part of the planning rules. But even outside heritage projects, they offer a timeless design that adds real character.
Key Features
Weight and Pulley System: Hidden counterweights inside the box frame allow the sashes to open and close effortlessly.
Timeless Design: Retains the classic charm and elegance of traditional sash windows, making them perfect for period properties and conservation areas.
Heritage Authenticity: Often required for listed buildings to maintain historical accuracy.
Box sash windows are an ideal choice for those looking to preserve the heritage character of their home while benefiting from modern improvements.

Victorian Sash Window
If your home was built in the mid to late 1800s — or you’re going for that look — Victorian sash windows are the style to match. With their classic two-over-two pane layout, they let in more light and offer a cleaner, more refined design than earlier styles.
You’ll often see them on Victorian terraces and townhouses across London. We build each one to suit your property, using the right proportions, profiles, and details — including run-through or plant-on horns where needed.
Key Features
Two-over-Two Design: Two panes in each sash, allowing for more natural light.
Decorative Horns: Often include run-through or plant-on horns for added style and authenticity.
Timeless Aesthetic: Perfect for both period homes and modern renovations.
Victorian style windows offer a beautiful blend of historical charm and modern practicality, making them a popular choice for homeowners looking to retain a period appearance.
-
Georgian Sash Window
If you’re restoring a Georgian home or want that classic, balanced look, Georgian sash windows are a smart match. With their six-over-six grid pattern and slim glazing bars, they bring symmetry and elegance to any property.
We build each window to suit your space — keeping the proportions right, matching profiles, and offering modern upgrades like double glazing where needed. Whether you’re replacing originals or adding character to a new build, we’ll make sure they feel like they’ve always belonged.
Key Features
Six-over-Six Design: A classic layout that creates a timeless, balanced look.
Slim Glazing Bars: Narrow bars that divide the panes, enhancing the window’s elegance and allowing for more natural light.
Traditional Aesthetic: Ideal for heritage properties and conservation areas.
Georgian sash windows are a perfect choice for maintaining the historical authenticity of a property while providing modern energy efficiency with double-glazing options. They are widely admired for their classic, symmetrical beauty.
