The problem

Presentation on a working commercial site

The exterior of an office is part of the visitor experience. Weathering, traffic film, organic growth and staining gradually leave façades, entrances and surrounding hard surfaces looking tired, even when the building itself is well managed.

On a business park, presentation has to be managed across more than one building, elevation and surface: entrances, cladding, paths, forecourts, gutters and roof areas. We survey the site as a whole, prioritise the areas that need attention and specify one-off work or planned preventative maintenance (PPM).

The work has to fit the day-to-day use of the property without becoming another task for the property team. Chiltern Surface Co takes responsibility for the survey, specification, mobilisation, delivery and handover, and plans the works to reduce avoidable disruption for occupiers, visitors, deliveries and on-site teams.

Occupied buildings
Working around staff, tenants and visitors needs clear sequencing. Works are phased zone by zone behind agreed exclusion areas, so access can be maintained wherever the site conditions allow.
Shared roads and pedestrian routes
Business parks often have busy entrances, paths, parking areas and delivery points. Traffic through them sets the work zones and the order of works, which are agreed with you before mobilisation.
Mixed exterior materials
Modern offices can combine coated cladding, render, brick, masonry, glazing surrounds and paving. Excessive or unsuitable pressure can affect coatings, joints and more delicate materials.
Multi-building consistency
Where a site includes several office blocks, one coordinated specification of works sets a consistent standard across the estate rather than treating each area in isolation.

What we do

Buildings and external areas in one specification

The combination of work depends on the materials, condition and priorities found at the survey. We identify each surface and the cause of the discolouration, then specify the pressure, water flow, cleaning products and application method for the material and its condition. Where a test area would help confirm the expected response, it is agreed at the survey. That gives facilities teams a clear basis for the proposed work and helps protect the finish of the building.

Building surfaces

  • Building surfaces

    Façade cleaning

    Atmospheric soiling, organic growth and surface staining removed from office elevations.

  • Building surfaces

    Cladding cleaning

    Coated metal and other cladding systems on office elevations.

Roofs and high level

  • Roofs and high level

    Roof cleaning

    Moss, algae and other biological growth on suitable commercial roofs, specified once the roof covering, condition and access have been surveyed.

  • Roofs and high level

    High-level access cleaning

    Difficult-to-reach areas cleaned from our dedicated tracked spider lift, operated by IPAF-accredited Chiltern Surface Co technicians.

Entrances and hard surfaces

  • Entrances and hard surfaces

    Car park and walkway cleaning

    Approaches, steps, pathways, parking areas and shared external spaces: the high-visibility areas staff and visitors use every day.

  • Entrances and hard surfaces

    Pressure washing

    Built-up grime and organic deposits removed from entrance paving and forecourts.

One-off and planned work

  • One-off and planned work

    Planned preventative maintenance (PPM)

    A one-off clean before a new tenant arrives, a property inspection, a launch or planned works, or planned preventative maintenance (PPM) to keep prominent areas at a consistent standard.

Safety and site control

Planned before we arrive

Roofs
We identify the roof covering before any work is proposed and request the asbestos register. Asbestos-cement and fragile roofs are never pressure-washed or walked on.
Wash water
We plan wash-water control and drain protection for every site.
Listed and conservation buildings
We use test areas and low-pressure methods on listed and conservation-area buildings.

Questions

Offices and business parks FAQs

What exterior areas can be included?

Façades, render, cladding, roofs, gutters, entrances, pathways, forecourts, parking areas and other external hard surfaces. We confirm the areas and methods in the specification of works after surveying the property.

Can you work around an occupied office?

Yes. We take occupancy, entrances, pedestrian routes, deliveries and vehicle movements into account at the survey and sequence the works around them. Out-of-hours working is available where the site needs it.

Can you cover an entire business park?

Yes. We survey the buildings and shared external areas together, prioritise by condition and access, and price façade, cladding, gutter, roof and hard-surface work in one fixed-price proposal, so you do not have to organise each area separately.

What do we receive when the work is finished?

A completion report: the works completed against the specification, before-and-after photography, defects found during the works, items outside the specification that need your attention, and sign-off. Where justified, it ends with a planned preventative maintenance (PPM) proposal and a suggested review cycle.

How often should office exteriors be cleaned?

There is no single cycle for every building. Location, exposure, traffic, nearby vegetation, surface finish and presentation standards all affect how quickly soiling returns, so where planned preventative maintenance (PPM) is justified, the completion report suggests a review cycle for each area rather than one schedule for the whole site.

Which areas do you cover?

Buckinghamshire, Oxfordshire and Berkshire, from our base in Marlow.
