1 - 6 Lombard Street, London.

Introduction

​

​This case study details the restoration of windows at the historic 1-6 Lombard Street property in London, undertaken for Canada Life c/o Parkeray. The project drew upon the expertise of TRC Windows and reflects the high-quality standards exemplified by our past projects.

​

Project Background

1-6 Lombard Street is a prominent Grade II Listed building in the heart of London's financial district next to Mansion House and opposite the Bank of England. Constructed in the 1905-1908 and modified in 1915 by notable architects Dunn and Watson with Curtis Green, the property boasts a rich architectural heritage. However, running time and weather elements had taken their toll on the building including original windows, compromising their aesthetics and functionality.

Client Objectives

Canada Life, the property owner represented by Parkeray, sought a comprehensive restoration solution for the windows at 1-6 Lombard Street. Their key objectives included:

• Preserving the historical integrity of the windows while enhancing their visual appeal.

• Improving energy efficiency to reduce heating and cooling costs.

• Ensuring structural integrity and weatherproofing to protect the building interior.

​

Solution

​

​TRC Windows was selected to carry out the window refurbishment works. The company is a specialist in the refurbishment of timber windows. We use a variety of techniques, including the Repair Care resin system, to repair and restore old windows. Draught proofing system Draftfix was applied to improve thermal and noise reducing performance of windows.

​

​

Repair Care Resin System

​

​The Repair Care resin system is a minimally invasive method of repairing and restoring old windows, so there is no need to remove the windows from the building. It involves applying a resin into the removed decayed wood areas of the window, which then solidifies to form a strong and durable repair. It is also a very versatile system, and it can be used to repair a wide range of damage. For bigger repairs and sills, timber splicing procedures were employed using like for like timber species.

​

​

​Refurbishment Process

​

​The refurbishment process began with a survey of the windows to assess their condition. Once the survey was complete, TRC Windows produced a refurbishment plan for each window.

​

​The restoration works were carried out on a window-by-window basis. The first step was to remove the rotten parts and clean the window frame. The Repair Care resin system was then used to repair any decayed wood in the frame and sashes.

​

​Once the timber repairs were complete, the old glazing putty was removed where necessary and replaced with modern putty alternative properly securing and sealing the glass. The windows were then primed to protect the repairs and be ready for decoration.

​

​Results

​

​The refurbishment of the windows at 1-6 Lombard Street was a success. The windows are now more energy efficient, secure, and weathertight. The appearance of the buildings has also been improved.

​

​Benefits to the Client

​

​The client is pleased with the results of the refurbishment. The old windows are restored to the condition they remain serving another cycle and being more secure, aesthetically pleasing and functionally sound.

​

​The works were carried out with minimal disruption being implemented on a floor by floor basis phased to a programme aligned with existing tenant leases. The TRC Windows team was professional and efficient, and we completed the works on time and within budget.

We have since been invited back to continue with another phase of works being caried out early 2025.

​

Conclusion

​

​The project on the windows at 1-6 Lombard Street is a good example of how well-chosen materials combining with extensive expertise can be implemented in practice to restore and prolong the use of existing timber windows.
