15-Storey Builders Window Cleaning Project in Peterborough: A Professional Rope Access Case Study

Ropeguys completed a complex builders window cleaning and post construction window cleaning project on a 15-storey building in Peterborough. The works were delivered over two weeks by a 3-person team of IRATA rope access technicians using the building davit system, specialist cleaning products, traditional window cleaning equipment and controlled glass restoration cleaning techniques.

Builders window cleaning is the specialist cleaning of glazing, frames and façade interfaces after construction or refurbishment work. It is very different from routine commercial window cleaning. On a live construction handover, glass is often contaminated with cement residue, silicone, paint splashes, construction dust, adhesive marks, protective film residue and general builders debris. If the wrong method is used, the glass can be scratched, etched, stained or left with permanent marks.

Post construction window cleaning is one of the most technical cleaning sectors because it sits between façade access, glass care, construction sequencing and safety management. A contractor has to understand how contaminants behave on glass, how to test a cleaning method before committing to a full elevation, how to protect frames and seals, and how to work safely around newly completed building fabric.

For high-rise and difficult-access buildings, professional rope access window cleaning contractors are often the most practical solution. Rope access gives trained technicians direct access to the glass without scaffold, mast climbers or large mobile elevated work platforms. On this Peterborough project, the height, façade layout and construction programme made rope access the right method for completing a safe, efficient and detailed builders clean.

Project Overview

The project involved a 15-storey building in Peterborough, UK, where Ropeguys was asked to complete builders window cleaning, post construction window cleaning, commercial façade cleaning and glass restoration cleaning. The programme ran for two weeks and was delivered by three IRATA rope access technicians. The building was accessed using a davit system, with the team working systematically across the elevations to remove construction contamination from glass and surrounding façade elements.

The scope included cleaning external windows affected by cement residue, silicone residue, construction dust, protective film residue, paint splashes and builders debris. These are common issues at handover stage, but they require careful treatment. Cement can bond to glass and frames. Silicone can smear if it is not removed correctly. Protective film adhesive can leave a persistent residue. Paint splashes and construction dust can create scratching risks if they are dragged across the glass.

The building height created additional planning requirements. Access points, rope lines, exclusion zones, rescue planning and weather exposure all had to be considered before works could begin. The objective was to restore the glazing and façade appearance while keeping the project efficient, controlled and safe for the site team below.

Initial Site Assessment

Before starting any high-rise builders clean, Ropeguys assesses the site, façade arrangement, access system, contamination type and project constraints. On this project, the team reviewed the davit system, the areas requiring cleaning, likely drop zones, access restrictions and the condition of the glass. This stage is essential because post construction window cleaning can vary significantly from one elevation to another.

RAMS were prepared to cover the rope access methodology, working at height hazards, use of cleaning tools, dropped object controls, PPE requirements, communication methods and emergency arrangements. Rope access is only efficient when it is planned properly. The team also considered rescue planning, including how a technician could be reached and recovered if assistance was required while suspended on ropes.

The assessment also included practical cleaning trials. Builders clean window cleaning should never rely on aggressive scraping across the full façade without testing. Small areas are tested first to confirm that cement residue, silicone residue and adhesive contamination can be removed safely. The trial helps determine whether professional scrapers, Unger Rub Out pads, specialist products or a staged cleaning approach is most suitable.

Challenges Encountered

The main challenge was heavy construction contamination. Cement residue was present in areas where wet trades and façade works had affected the glazing. Cement on glass is particularly sensitive because incorrect removal can scratch the surface or leave mineral staining. The Ropeguys team used controlled methods, keeping the glass wet where required and using professional-grade tools only after testing.

Silicone residue was another important issue. Silicone can be difficult to spot until light catches the glass at an angle. It can also smear and spread if the wrong product or cloth is used. Ropeguys treated silicone contamination with care, using professional scrapers, specialist products and glass-safe pads where suitable.

Protective film residue and builders dust added further complexity. Film residue often leaves adhesive marks around edges or across panes, while dust can act like an abrasive if it is not removed in stages. The team avoided dragging dry contamination across the glass and worked methodically to reduce the risk of scratching.

Working at height added environmental exposure. Wind, rain, temperature and daylight all influence high rise window cleaning. A rope access team must be able to pause, adjust sequencing or change working methods if weather conditions reduce safety or cleaning quality. This is one of the reasons specialist window cleaning contractors are needed for high-rise post construction work.

Rope Access and Davit System Setup

The access method for this project was a davit system. A davit system allows rope access technicians to position ropes from approved high-level points so that elevations can be accessed without scaffold. Before use, the team checked the setup, inspected equipment, confirmed working lines and backup lines, and planned descent routes for each work area.

IRATA rope access methods use a two-rope system: a working rope and a safety backup rope. Technicians use harnesses, descenders, backup devices, connectors and other rope access equipment to position themselves safely. Each technician remains attached to independent systems, and the team works under a planned rescue arrangement.

On this project, the davit system gave the team flexible access to glazing that would have been difficult and expensive to reach with scaffolding. It also reduced disruption around the building. For post construction window cleaning, this flexibility matters because teams often need to return to specific panes, inspect areas from different angles and work around site constraints.

Equipment Used

The equipment package combined rope access equipment with specialist builders clean tools. The access equipment included harnesses, ropes, descenders, backup devices, connectors, helmets, rope protection, tool lanyards and PPE. The cleaning equipment included traditional window cleaning applicators, squeegees, professional scrapers, Unger Rub Out pads, specialist cleaning products and clean cloth systems.

Traditional window cleaning equipment was used once construction contamination had been dealt with. This is an important distinction. Routine applicator-and-squeegee cleaning is not enough when cement residue, silicone and adhesive marks remain on glass. The glass first needs a controlled restoration process, followed by a final traditional clean to remove water marks, loosened residue and remaining dirt.

PPE and tool control were also important. Rope access window cleaning at this height means tools must be managed carefully to prevent drops. Buckets, scrapers, pads and applicators are controlled, and exclusion zones below are considered as part of the RAMS.

Step-by-Step Cleaning Process

Step 1: Initial Inspection

The team inspected the glazing and façade areas to identify cement residue, silicone, protective film residue, paint splashes and dust. The inspection helped decide where detailed glass restoration cleaning was required and where a lighter post construction clean would be sufficient.

Step 2: Access Setup

The davit system and rope access equipment were set up in line with the RAMS. Working lines, backup lines, equipment checks and communication arrangements were confirmed before descent.

Step 3: Testing Cleaning Methods

Small test areas were cleaned first. This allowed the team to confirm that the chosen method removed contamination without scratching or damaging the glass.

Step 4: Removal of Construction Debris

Loose builders debris and dust were removed in stages. This reduced the risk of abrasive particles being dragged across the glass during later cleaning.

Step 5: Removal of Cement Contamination

Cement residue was treated carefully using tested methods, keeping the process controlled and glass-safe. Heavy residue was addressed before final cleaning took place.

Step 6: Removal of Silicone Contamination

Silicone residue was removed using professional scrapers, pads and suitable products. The team avoided smearing the contamination across clean glass.

Step 7: Removal of Protective Film Residue

Adhesive and film residue were removed where present, particularly around pane edges and areas exposed during the construction phase.

Step 8: Traditional Window Cleaning

Once the heavy contamination was removed, traditional window cleaning equipment was used to wash and squeegee the glass for a clean finish.

Step 9: Glass Polishing

Where required, glass was detailed and polished to remove smears, final residue and marks visible in changing light.

Step 10: Final Quality Inspection

The team inspected completed sections before moving on. Final checks are important because builders clean window cleaning is judged by detail, not just general appearance.

Why Rope Access Was the Best Solution

Rope access was the best solution because it provided direct access to a 15-storey façade without the cost and disruption of scaffold. For high rise window cleaning, rope access can be deployed quickly, adjusted as work progresses and used on elevations where ground-based equipment is impractical.

The method also reduced disruption. On construction and handover projects, space around the building can be limited by other trades, deliveries, residents, site welfare, plant or landscaping. A rope access team can often work above these constraints with smaller exclusion areas and less site footprint than scaffold or large machines.

Safety is improved when the method is planned correctly. IRATA rope access is a structured system with trained technicians, two-rope working, backup devices, rescue planning and documented procedures. For Ropeguys, this makes rope access a practical and professional method for specialist high-level cleaning.

There are environmental benefits too. Rope access uses less temporary material than scaffold, can reduce transport and plant requirements, and can often complete work with less disruption to the building and surrounding area.

Project Results

The project was completed safely within the two-week programme. Ropeguys restored the glazing affected by cement residue, silicone residue, dust, protective film residue, paint splashes and general builders debris. The completed façade had a cleaner, sharper appearance suitable for handover and occupation.

The result demonstrates why builders window cleaning should be treated as a specialist package rather than a routine clean. The combination of glass restoration cleaning knowledge, rope access planning, professional equipment and experienced technicians helped deliver a controlled finish across a high-rise building.

The client benefited from a reduced access footprint, a safe working method, clear RAMS, specialist high-rise expertise and a completed façade that reflected the quality of the development.

Before and After Comparison

The comparison shows the difference between contaminated construction-stage glazing and the final cleaned façade. On post construction projects, improvement is not only about shine. It is about removing bonded residue, restoring clarity, reducing handover defects and protecting the long-term appearance of the glass.
