Façade Restoration and Stone Cleaning Contractors Insurance
Façade restoration contractors clean, repair and protect the external surfaces of buildings: stone and brick cleaning, mortar repairs, stone indents, repointing, consolidation, render repair and the application of water repellents and anti graffiti coatings. Much of the work is on older and listed buildings in town centres, where the fabric itself may be irreplaceable.
Cleaning methods range from gentle water misting and superheated steam to low pressure abrasive systems, chemical cleaners, poultices and laser cleaning. Each suits some substrates and damages others. Choosing the wrong method, or using the right one too aggressively, can strip the surface of a stone or leave staining that cannot be reversed.
Work on listed buildings and in conservation areas may require consent before it starts, and unauthorised works to a listed building can be a criminal offence. Conservation officers, architects and heritage bodies often specify materials and methods, and restoration contractors are expected to follow those specifications or flag their concerns.
We can help you arrange cover that reflects the methods you use, the buildings you work on and how much of the specification is yours. That typically means liability cover that considers damage to the building being worked on as well as neighbours and passers by, professional indemnity where you advise on methods and materials, and cover for your cleaning and access equipment.
Common claims and risk exposures
The exposures that produce claims in this trade, rather than a generic list.
Damage to historic fabric
Over cleaning can remove the protective surface of sandstone or limestone, erode carved detail or open up the stone to faster weathering. Damage to irreplaceable heritage fabric is costly to repair and difficult to value, and disputes often involve conservation specialists on both sides.
Chemical and abrasive overspray
Acid and alkaline cleaners can etch glass, damage polished stone and stain paintwork. Abrasive systems can pit glazing and mark vehicles parked below. Run off may enter drains or damage planting. Sheeting, masking and control of the work area are what keep these from becoming third party claims.
Falling masonry and dropped objects
Loose stone, failing cornices and spalled render can fall when disturbed. Façade work often happens above pavements and entrances, so protection fans, debris netting and exclusion zones are essential, and a falling piece of stone can cause serious injury.
Inappropriate repair materials
Hard cement mortars and impermeable coatings on traditional masonry can trap moisture and cause spalling over years. Where a contractor chose or recommended the material, the long term deterioration may come back as a claim about the advice rather than the workmanship.
Silica, lead and asbestos
Cutting out joints and dressing sandstone can release respirable silica. Old paint layers on façades may contain lead, and some textured coatings and renders can contain asbestos. These are long tail employers' liability exposures and need surveys and control measures before work begins.
The cover we arrange
We arrange insurance around the work you carry out, the contracts you take and the sites you work on. The cover available will depend on the individual risk and the terms offered by insurers.
Public liability
Third party injury and property damage, including damage to neighbouring buildings, vehicles and passers by. Many wordings also need to address damage to parts of the building you are working on, which is where heritage claims arise. City centre and heritage work commonly requires £5m or £10m.
- Overspray damage to glass, vehicles and finishes
- Injury from falling masonry
- Damage to neighbouring property
- Limits typically £5m or £10m
Employers' liability
Employers' liability is a legal requirement once you employ people, and can be arranged where required, subject to the policy terms. Work at height, silica and lead exposure, and handling chemicals are the main exposures.
- Legal requirement once you employ people
- Work at height from scaffold and MEWPs
- Silica, lead and chemical exposure
- Labour only subcontractors
Professional indemnity
Important where you carry out condition surveys, recommend cleaning methods, specify mortars or coatings, or prepare method statements for consent applications. Responds to claims that the advice was negligent, which liability cover typically excludes.
- Condition surveys and trial panels
- Method and material recommendations
- Heritage consent method statements
- Claims made basis
Contract works
Covers repairs in progress, stone indents and replacement units on site, and the works against storm, fire and vandalism before handover. Natural stone units can be costly and have long lead times.
- Repair work in progress
- Replacement stone and materials on site
- Storm and vandalism damage
- Materials in transit
Plant and equipment
Steam cleaners, abrasive cleaning systems, pressure washers, laser cleaning units, mortar rakes and access equipment. Laser and specialist cleaning equipment is high value and worth listing individually.
- Steam and abrasive cleaning systems
- Laser cleaning equipment
- Owned and hired access equipment
- Theft from site and vehicles
What an underwriter will ask
Having these to hand shortens the process considerably, and usually improves the terms.
- The cleaning methods you use: water, steam, abrasive, chemical, poultice or laser
- The proportion of work on listed buildings or in conservation areas
- Whether you carry out trial panels before full cleaning
- Who specifies methods and materials: you, an architect or a conservation officer
- Whether you use lime mortars and breathable materials on traditional masonry
- How you protect glazing, vehicles, drains and the public below
- Asbestos and lead surveys before work starts
- Access methods: scaffold, MEWPs, mast climbers or rope access
- Five years of claims, including disputes over damaged fabric
What affects the cost of your insurance?
The main factors insurers consider when assessing the premium.
Heritage proportion
Listed buildings and conservation area work bring higher repair costs and more scrutiny of methods. The share of turnover on heritage buildings is a key rating factor.
Cleaning methods
Gentle water and steam cleaning carry less potential for damage than abrasive or chemical systems. Trial panels and documented method selection improve the presentation.
Advisory work
Contractors who survey, recommend and prepare method statements carry professional exposure. Those working strictly to an architect's or conservation officer's specification carry less.
Access and public protection
Work above busy pavements and entrances raises the third party exposure. Protection fans, netting and exclusion zones help demonstrate control.
Conditions and exclusions to consider
Terms vary between insurers, so treat these as the questions to ask rather than a description of any one policy.
Property being worked on
Many liability policies exclude damage to the part of a building you are working on. On a façade, that can be the very stone you are cleaning. Some wordings provide limited cover, others none, and on heritage buildings that gap needs to be understood.
Advice and specification
If damage results from choosing an unsuitable method or material, liability cover may exclude it as design or advice. Professional indemnity is where that exposure normally sits.
Gradual deterioration
Spalling caused over years by an unsuitable mortar or coating develops gradually. Policies that respond to sudden and accidental damage may not cover it.
Asbestos and pollution
Asbestos is excluded on most wordings, and some policies restrict pollution cover for chemical run off into drains or watercourses. If you use chemical cleaners regularly, check how pollution is defined in your policy.
Common questions
What insurance do façade restoration contractors need?
Typically public liability at £5m or £10m, with attention to damage to the building being worked on as well as neighbours and the public. Employers' liability is a legal requirement once you employ people and can be arranged where required, subject to the policy terms. Professional indemnity is worth having where you survey, recommend methods or specify materials, and contract works and plant cover protect the job and your cleaning equipment.
Am I covered if stone cleaning damages a listed building?
It depends on the wording. Many liability policies exclude damage to the part of the building you are working on, which can include the façade you are cleaning. If the damage arises from choosing an unsuitable method, it may be a professional indemnity matter. Trial panels approved by the client or conservation officer, and records of the method agreed, help show the work was carried out as specified.
Who is responsible for getting listed building consent?
Usually the building owner or their agent applies, but contractors can still be involved if work goes ahead without the required consent. Carrying out unauthorised works to a listed building can be a criminal offence. Before starting work on a listed building, ask to see the consent and any conditions attached to it, and follow the approved method statement.
Does my policy cover overspray damage to cars and windows?
Damage to third party vehicles, glazing and property from chemical or abrasive overspray is normally a public liability matter, subject to the policy terms and excess. Good masking, sheeting and exclusion zones are the practical controls. Frequent small overspray claims can affect renewal terms, so many contractors manage minor incidents carefully and keep photographic records of protection measures.
Do I need professional indemnity if I recommend lime mortar or coatings?
Yes, it is worth considering. Recommending a mortar, consolidant or water repellent is advice, and if it proves unsuitable the damage may develop over years. Liability cover typically excludes claims arising from advice or specification. Professional indemnity is written on a claims made basis, so it needs to be kept in force while claims could still arise.
