Timber Sash Windows

Our timber sash windows are ideal for period properties, crafted to preserve their traditional elements while providing modern energy efficiency and durability. Sustainably sourced and expertly made, these windows are perfect for conservation areas.

uPVC Sash Windows

For those seeking a low-maintenance option, our uPVC sash windows offer the timeless look of timber without the upkeep. uPVC frames are incredibly durable, energy-efficient, and resistant to weathering, making them an ideal choice for busy homeowners.

Double Glazed Sash Windows

We also specialise in double-glazed sash windows, which boost your home’s insulation, helping to keep the space warm in the winter and cool in the summer. Our windows provide excellent noise reduction for properties in noisier parts of Greenwich, ensuring a more peaceful living environment.

Our commitment to sustainability ensures we only use FSC-certified timber, preserving both your home’s beauty and the environment. Every installation is backed by industry-leading warranties, including a 10-year guarantee on glazing and fittings, offering peace of mind alongside unmatched performance.

Our sash windows are designed with meticulous attention to detail, featuring traditional sash horns, custom mouldings, and bespoke finishes that honour the heritage of your property. We specialise in replicating original designs for homes in conservation areas, ensuring historical accuracy without compromising on modern performance.

Bespoke Design Features

From decorative details to advanced glazing options, every window is tailored to seamlessly integrate with your home’s unique architectural style while providing improved energy efficiency and security.

Added Security

Each sash window is fitted with robust locking mechanisms, including multi-point locks and reinforced fasteners, providing a strong line of defence against potential intruders. For added peace of mind, we also offer toughened glass, enhancing the durability and security of your windows without compromising on style.

Made for Heritage and Conservation Areas

In Greenwich, many homes are located in heritage or conservation areas, requiring windows that meet strict planning guidelines. We specialise in crafting bespoke timber sash windows that replicate the original designs of Georgian, Victorian, and Edwardian properties, ensuring historical accuracy. We collaborate closely with homeowners and local authorities, ensuring that every feature – from glazing bars to decorative mouldings – adheres to conservation standards.

Professional Sash Window Installation in Greenwich

Our expert installation process in Greenwich is designed to be smooth and stress-free.

It begins with a thorough consultation and survey, where we take precise measurements to ensure a perfect fit for your new sash windows. Then, on installation day, our skilled team works efficiently, using protective coverings to minimise disruption and keep your home clean.

After installation, we perform a detailed inspection to ensure everything is flawless before signing off. We also provide full aftercare support, offering advice on maintenance and handling any minor adjustments.

Our timber sash windows are treated to resist rot and decay, requiring only periodic cleaning and a light repaint every few years to maintain their appearance. uPVC sash windows are even easier to care for, needing just a simple wipe-down with a damp cloth to stay looking new.

We recommend an annual check for all sash windows to ensure smooth operation and address any minor wear. Should any adjustments be needed, our dedicated aftercare team is always on hand to provide support.
