TRC Windows

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 Background1-6 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 ObjectivesCanada 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.RecommendationsIf you evaluate refurbishing the timber windows in your building, we recommend that you consider using our methods with a several benefits over but not diverging from traditional repair methods.TRC Windows has a long track record of successfully refurbishing timber windows and we recommend that you contact us at TRC Windows.

Introduction ​ ​Campsbourne Primary School is a two-form entry primary school situated on the southern border of Alexandra Palace Park in Hornsey, London. The school was founded in 1890 and has a long and proud history. The buildings are a good example of a late Queen Anne style Board school and falls within the Campsbourne Cottage Conservation Area, designated in 1994, on grounds of the picturesque, art & crafts and cottage nature of the Campsbourne Cottage Estate. In recent years, the school has undergone a major refurbishment, which included the replacement of the windows. ​ ​The Problem ​ The old windows at Campsbourne Primary School were in poor condition. They were draughty, leaky, and inefficient. Most of the windows were covered in layers of old paint and stuck shut.

They are draught-proof, leak-proof, and energy-efficient. This has improved the comfort of the classrooms and has also reduced the school's energy bills. The new windows have also improved the appearance of the school buildings. ​ ​Project Details ​ ​The project to replace the windows at Campsbourne Primary School was completed in two phases to help school keep operational while undertaking construction activities. The first phase involved the works on the windows in the main school building Junior School. The new window sashes were produced by TRC Windows at the same time while refurbishing the original window frames and were made ready for installation as soon as frame refurbishment was completed.The second phase involved the replacement of the windows in the Infant School building replicating the same parallel refurbishment works and production tactics successfully used on the Junior School. ​ ​ The window sashes are made from high-quality materials and are designed to be school safe and energy efficient. The windows were installed by TRC Windows' experienced team of installers. ​ ​The project was completed on time and within budget. The new windows have been well-received by the school's students and staff. ​ ​Conclusion ​ ​The replacement of the windows at Campsbourne Primary School was a successful project. The new windows have improved the comfort, energy efficiency and appearance of the school building safeguarding the looks of conservation area. All works are covered by TRC 10 Years Warranty. We are proud to have been a part of this project, and we are confident that the new windows will provide many years of service to the school. ​ ​Testimonial ​ ​"We are delighted with the new windows at Campsbourne Primary School.

Introduction Originally known as Smoothfield, it was a large open space just outside the city boundaries on the edge of St Bartholomew’s Priory.In the 12th century it was used as a vast recreational area where tournaments and jousts took place. By the late Middle Ages the area had become the most famous livestock market in the country.Annexe buildings or Triangular Block consisting of two separate structures The Fish Market and Red House buildings at Smithfield Market in London are two of the most important historic buildings in the city’s market area. It was built between 1886 and 1899. Not in use since the mid-1970s the General Market and the adjacent Annexe buildings, have been facing a threat of demolition. Grade II listed building protection was approved for the Red House Cold Store building in 2005 on the basis of new historical evidence qualifying the complex as "the earliest existing example of a purpose-built powered cold store". The once-in-a-generation decision was taken to recreate and open in West Smithfield The London Museum from 2026. The Annexe buildings hold great potential to expand the cultural presence and truly transform the area. Both buildings were in need of significant refurbishment, including the refurbishment and replacement of their windows. Problem The existing windows in the Fish Market and Red House buildings were in poor condition. They were leaking, draughty, and inefficient, in some cases even falling apart. This was causing significant problems and buildings deterioration, including: Water damage to the buildings' interiorsCold drafts that would make the buildings unusableIncreased future energy billsSolution TRC Windows was commissioned to refurbish and replace the windows in the Fish Market and Red House buildings. The company used Repair Care system to refurbish and produced high-quality timber windows that were made to replicate the original windows. The refurbished and new windows are energy-efficient and will help to reduce the buildings' energy bills. They are also weatherproof and will help to protect the buildings from water damage. Fire rated windows have been made and installed where necessary to meet client requirements. Work The work to refurbish and/or replace the windows in the Fish Market and Red House buildings was carried out over a period of six months. The first step was to remove the old windows. This was a delicate process, as the windows were made of timber, with loose glazing and were in poor condition. Heavy scaffolding to hold weak building structures was a challenge to move around. Once the old windows were removed, they were moved to dedicated workshop on site for refurbishment. At the same time production of new windows started. The new windows were custom-made to fit the original openings and replicate the design of existing windows while modernising. They were also fitted with complex double glazing incorporating energy-efficient glass, anti-shatter film and seals. The refurbishment process consisted of complete disassembly followed by careful repairs of all window timber parts, re-glazing and decoration, then assembly and rebalancing. Improvements as draught exclusion were incorporated during works. Refurbished windows were installed to their original positions alongside new windows in to restored window openings.Results The refurbishment and new windows have been a success. They have restored the looks of original buildings, reduced the buildings' energy bills, made them more comfortable to work in, and protected them from further damage. The client is very pleased with the results of the refurbishment. Conclusion The refurbishment of the windows in the Fish Market and Red House buildings was a complex and challenging project. However, it was completed on time and has improved the buildings' condition and efficiency. The new windows are a valuable addition to these historic buildings and will help to ensure that they continue to be used and enjoyed for many years to come.

Dating from the late 18th century, Frederick’s Place in London EC2 had led an opulent past. With a late prime minister and several prominent business founders as its previous residents, this address also boasts St Paul’s Cathedral as a neighbour. This distinguished building can still be easily found nestled between museums, restaurants and art galleries in the old streets of the financial district, in the borough of the City of London.The original design of the building was by Robert Adam, a prominent English architect, and the building was named after the late Sir John Frederick, a 17th century Lord Mayor of London.Today however, this opulent building is now registered as Grade II listed, and is to be exquisitely transformed by John Robertson Architects into luxury office space on behalf of The Mercers’ Company.

TRC was commissioned in December 2015 to begin a 34-month project to refurbish the 850 sash windows, over 40 pairs of French doors and 30 replacement identical sash windows so they perform to expectation in such a high-end building, while retaining their heritage characteristics. TRC also designed, supplied and installed over 200 new timber/aluminium composite windows for an additional new building in the grounds. This included design to the developer’s requirements; producing prototypes to obtain planning approval; production; and installation by TRC’s own employed team of professional window installers.

TRC was appointed as principal contractor by Barker Associates in May 2019, to carry out specialist sash window restoration works.Trinity Primary Academy is a primary school located in Bounds Green Road, Wood Green, London. It was built in 1899 by Mitchell and Butler and consists of yellow brick and red brick dressings, tiled roofs, irregular fenestrations, and sash windows that give away its Queen Anne Revival style. It's currently categorised as a Grade II Listed building with Historic England, and is part of the Academies Enterprise Trust.Nature of the worksAs the building was Grade II listed, timber window repairs had to be sympathetic and complementary to the historic nature of the property. Many of the existing timber sash windows were inoperable due to the build-up of decorative coatings, timber degradation, and defective and broken sash window ironmongery, as well as opening mechanisms. The requirement was for the windows to be fully refurbished, repaired and operational as originally intended, but also modified to meet health and safety requirements.Phase one of the refurbishment of 200 sash and timber casement windows commenced on the area needing most attention: the west elevation of the building. Following the success of phase one, the client team extended TRC’s appointment to continue around the remainder of the building, systematically completing all other windows, door and roof light refurbishments.This overall refurbishment project included:Stripping back the existing paint from the historic sash windows and repairing any decayed timber.Repairing glazing as and where necessary.Improving the thermal and acoustic containment by installing draughtproofing.Repainting windows and installing ironmongery.Undertaking brick and stone repairs to the building’s exterior.This project also required our specialist attention on some specific areas of traditional glazing. This aspect of the project required the repair and refurbishment of all four oriel bay windows and the oriel bay glazed roofs. Completion included the supply and fixing of new safety glazing and hardwood timber roof rafters, along with the repair and refurbishment of the two existing openable roof lights. The supply and fixing of new code 4 lead flashing, with lead wedges, was also carried out and fully pointed with the correct cement mortar at the wall abutment.Additional detailed work throughout the project included the following:Removal of all existing fitted window blinds for refixing upon completion of works.Removal and repair of existing window ironmongery, including original mechanical winding gear, solid bar opening mechanisms, locking fasteners, slide bar restrictors, cable restrictors, handles and stays.Careful removal and repair of all internal fixed-glazed hopper units, casements and pivot openings.Removal and replacement of all cracked and broken glazing, and replacement of the existing Georgian wired-glazing, with 6mm safety glass or 4mm polished plate glass to areas up to 1.2m height from floor level. Where privacy was required, white opaque glass with thickness in accordance with above was used.Removal and replacement of all loose and defective glazing putties, and removal of all flaking, loose and built-up paint coatings.Exposure of all timber rot and decay ready for repair with Repair Care Systems products, followed by sanding and priming ready for decoration.Vertical sliding sashes repaired, refurbished and rehung on new sash cords and weights, and adjusted as needed. Sashes were routed to accept new brush pile weather stripping. New parting beads and staff beads were serviced with brush pile weather stripping where appropriate.Final internal and external decoration was carried out using Dulux or Leyland trade paints, allowing for one undercoat and one gloss finish.

TRC was awarded the 14-month contract to design, supply and install 300 timber box sash windows, 50 balcony French doors, and 28 curved-on-plan sash windows.
