For years, commercial landlords and property maintenance executives have favoured replacement as the definitive fix for a tired facade. But that mindset is shifting, largely influenced by public sentiment and environmental policy direction.
The introduction of RICS’ Whole Life Carbon Assessment (second edition) in mid-2024 means that commercial property owners now have to compare the carbon impacts of options like refurbishment against replacement.
Once you include whole-life carbon emissions and total cost of ownership, a refurbishment-first strategy almost always wins. In our own project data, refurb typically costs around 1/20th (5%) of full replacement, and avoids the unnecessary emissions spike that comes with manufacturing, transporting and installing new systems.
Why carbon tips the scales in facade replacement
There’s now broad agreement on the scale of embodied carbon in buildings. The UK Green Building Council estimates that the construction and refurbishment of buildings account for 20% of UK built-environment emissions. That is before a single kilowatt of operational energy is consumed.
On facades specifically, a recent study by building consultancy firm Arup calculated cradle-to-grave embodied carbon of up to 520 kg of CO₂ equivalent per m² of facade depending on system type and design. In other words, ripping off and replacing curtain wall or rainscreen carries a large, front-loaded carbon cost.
Refurbishment sits at a fraction of that footprint because you retain most of the existing fabric. Activities like restorative cleaning, DOFF Steam Cleaning, general repairs and selective component swaps extend life without starting from scratch.
The bottom line is that every time you extend the life of an existing facade through in-situ restoration, you save hundreds of kilograms of CO₂ per m² and keep future options open.
The hidden cost of deferring facade restoration
One common mistake is to delay restoration works. The National Audit Office reports that deferring backlog maintenance can push costs up by more than 50% in as little as two to four years. The dynamics are the same in commercial portfolios: reactive programmes are pricier, more disruptive and harder to schedule than planned interventions.
A refurbishment-first plan prevents facade deterioration from crossing the threshold where replacement becomes unavoidable. It also improves tenant sentiment and leasing outcomes. Retail research shows exterior condition strongly influences purchasing decisions and visit intent, reminding landlords that “first impressions” are not a cliché but a strategic business advantage.
What does facade refurbishment actually mean?
Facade refurbishment is much more than just a wash-down. It is a targeted set of activities that extend service life:
- Cleaning with the least-aggressive effective method (for heritage and delicate substrates, DOFF Steam Cleaning: high temperature, low pressure).
- Localised repairs: re-pointing, sealant renewal, gasket replacement, remedial fixes to fixings or sub-frames.
- Selective coating renewal on metals and trims; protection where appropriate.
- Moisture management: gutters, flashings, joints and drainage detailing to stop the causes of staining and ingress.
This approach aligns with general conservation practice and with RICS’ Whole Life Carbon Assessment: preserve what you can, replace only what you must.
The climate context: why facade problems are accelerating
The UK is moving towards wetter, milder winters and hotter, drier summers (something we explored in our previous blog). The UK’s Met Office predicts winters up to 30 per cent wetter and summers up to 60 per cent drier by the 2070s, with warmer conditions overall.
These shifting weather patterns are the perfect recipe for facade decline: damp seasons that feed biological growth followed by hot spells that bake particulates and deposits into the surface. Planned, light-touch refurbishment prevents this “rinse-then-bake” cycle from becoming structural damage.
Carbon and cost, side by side
Consider a simplified comparison for 1,000 m² of facade area on a small to medium commercial building.
Facade replacement
Using Arup’s range of 160 to 520 kg of CO₂ equivalent per m², the total embodied carbon impact is roughly 160 to 520 tonnes of up-front CO₂ equivalent, plus waste transport and end-of-life impacts. That’s in the ballpark of the embodied carbon for up to ten typical new-build homes in the UK.
These calculations don’t even begin to consider the additional cost and downtime needed to replace an entire facade.
Facade refurbishment
Restorative cleaning and targeted repairs avoid most emissions. Even with modest component swaps, embodied carbon is a small fraction of replacement. Cost is typically about five per cent of replacement on a See Brilliance restoration programme. Works can also be delivered while the building remains open, which reduces disruption and avoids further additional cost for occupiers.
When refurbishment is right and when it isn’t
Refurbishment is the right starting point when issues are cosmetic or localised. Think staining, algae build-up, concrete splatters or early surface wear. A survey and test panels usually confirm that cleaning and targeted restoration will recover appearance and performance.
Of course, refurbishment is not suitable where safety or integrity is in doubt. If fixings are failing, fire performance cannot be assured, water ingress is systemic, or coatings have failed across large areas, the responsible course is to plan replacement. Listed buildings may also require methods that trials show cannot be delivered safely in situ.
For most projects, a short diagnostic phase that tests restoration effectiveness on representative areas will determine whether refurbishment is the best option.

Refurbishment preserves fabric, cuts embodied carbon, shortens programmes, reduces business interruption, and typically costs about five per cent of replacement. Add in the National Audit Office’s warning about the cost of maintenance deferral, and the wider benefits are obvious.
