Ely sits on its low rise of firmer ground in the Cambridgeshire Fens, a cathedral city surrounded by drained black earth, long straight droves and farm buildings that stand out in the open with nothing to break the wind. The businesses here range from brick and rendered premises in the old centre to steel-framed units on the city’s edge and large agricultural stores spread across the surrounding fenland. The commercial coating Ely buildings need must account for this varied stock.
What every one of those buildings has in common is exposure. We are survey-led exterior coating contractors, and for commercial coating Ely owners are often surprised by the answer: some roofs and walls are ready for coating, and some are past it. We inspect the building first, put our findings in writing, and only then say whether a coating is the right spend at all.
How commercial coating Ely projects respond to fenland weather
With little between the city and the Wash to slow it down, wind crosses the open fen at full strength and drives rain sideways into laps, flashings and fixings that would stay dry in more sheltered country. Ely stands on the flattest land in the UK, and that geography sets the pattern of wear we see on survey.
Elevations facing the fen take a sustained wetting and drying cycle that finds every weak joint, every tired patch of render and every hairline crack in old paintwork. Roofs chalk and fade on the weather side first, sealants give out early at exposed details, and moisture creeps into sheet overlaps to start corrosion from the inside.
The building stock itself is mixed. Around the centre there are older solid-walled and rendered properties in trading use; on the edge of the city sit portal-frame units and trade premises serving the Cambridge corridor; and out across the fens are grain stores, packhouses, machinery sheds and food-handling units, many roofed in profiled metal, fibre cement or corrugated asbestos cement laid down decades ago. Older walls and modern framed units stand side by side, and the treatment that suits one is frequently wrong for the other. That is the call the survey exists to make.
Commercial roof coating in Ely
On exposed commercial roofs around Ely the structure is often still sound while the surface, seams and details have been worn open by weather. For commercial coating Ely roofs must first be checked for faults that could make coating unsuitable. A liquid membrane roof coating is built up over a prepared roof, sealing the laps, flashings and fixings into one continuous waterproof layer and letting existing sheets serve on without the disruption of re-sheeting. Whether a given roof is a candidate is a question of its condition, established by survey and never by a call over the phone.
If you have been searching for commercial painters in Ely, it is worth knowing that an airless-sprayed coating system built for these conditions normally outlasts a brush-and-roller repaint on a large span. We see the same failure points again and again: cut-edge corrosion where wind-driven rain sits on sheet ends, fixings worked loose by constant wind load, and laps opened just enough for capillary action to do its worst. Caught before the deck itself suffers, all of it is fixable. Where insulation is already wet or sheets have corroded through, we say so and recommend repair or replacement instead.
Commercial wall coating in Ely
Wall work here starts with an inspection of the actual wall, not a product catalogue. A commercial coating Ely wall survey checks the render, the brick and the exposure, takes moisture readings and adhesion checks, and finds the cause of a defect before anyone specifies a system. On a wind-battered elevation a coating applied over trapped moisture will fail early, and the remedial cost lands on the owner, so the diagnosis has to be based on readings rather than a look from the kerb. A commercial wall coating is only worth applying once repairs and preparation have dealt with what the exposure has done to the wall.
An exterior painting programme kept to a plan beats emergency call-outs every time, and along the A10 and across the fens that means catching failed fixings, chalking render and early water ingress while the repair is still small. Not every survey ends with a coating. Cracks that follow a structural pattern need investigating first, hollow-sounding render has to come off rather than be sealed in, and some of the older solid-walled buildings near the centre need a breathable treatment or none at all. Whatever the evidence supports goes in the written report, even when it costs us the job.
Cladding spraying in Ely
Cladding is where the gap between looking tired and needing replacement is narrowest, and only an inspection tells you which side of the line your building sits. For commercial coating Ely cladding must be assessed before its colour or protective finish is renewed. We coat commercial, industrial and agricultural cladding, renewing the colour and the protective finish on profiled steel and composite panel that has weathered but stayed sound. Cladding spraying is carried out in even passes over a prepared surface, with adhesion testing, corrosion mapping at cut edges and gutter lines, and a check of fixings, sealants and flashings done first.
Not every panel can be saved. Finishes delaminating wholesale, sheets perforated by corrosion and elevations hiding active leaks all need repair before a spray gun comes near, and a coating cannot improve a panel system’s fire performance; that is a question for a fire specialist, and we will tell you so. Where cladding painting does make sense, it protects the envelope rather than just refreshing the colour, paying particular attention to the cut edges and flashings that let the fen weather in.
Industrial roof coating in Ely
Ely’s industrial estate buildings are mostly steel portal frames with profiled metal roofs, serving the agricultural, food processing, storage and distribution businesses of the area. Many have been up long enough for the original factory finish to be on its last legs. An industrial roof coating bonds across the whole sheet, seals the laps and fixings the weather has loosened, and replaces that worn finish with a continuous weatherproof layer, all without opening the building envelope, so hygiene-controlled and always-busy operations keep trading below.
Owners who have compared industrial painting contractors tend to find the difference is in the survey, not the spray. That makes the survey central to commercial coating Ely industrial roofs can rely on. Done on a surveyed deck, a roof coating adds service life; done blind, it hides the faults until they leak. We programme the work around busy periods, agree access and vehicle movements with the site team, and sequence the roof in sections so production carries on. Where we find widespread perforation, weakened fixings or saturated insulation, the answer is repair or replacement, and we put the reason in writing.
Cut edge corrosion treatment in Ely
Every profiled steel roof shares the same manufacturing shortcut: sheets are cut to length, leaving the steel core bare at every end and overlap where the factory coating never reached. That is exactly where rust starts, showing first as staining along the eaves and laps while it quietly lifts the coating from the steel underneath.
Out on the fens the laps pull wind-driven rain in by capillary action and hold it against that bare metal, and on grain stores and livestock buildings condensation attacks the underside at the same time. A cut edge corrosion treatment cleans the corroded edges back to sound metal, primes them, seals the laps and finishes with a flexible band over the vulnerable zone.
Caught early, this is a contained repair, and the building stays in use while we do it, which matters when nobody wants a roofing job in the middle of harvest storage. Left too long, the steel keeps thinning until it perforates, and at that point the sheet has to be replaced rather than treated. The survey answers two questions: how far the edge corrosion has travelled, and how much life is left in the rest of the roof’s coating. The limit is perforation or heavy loss at the laps, where we advise replacing the worst sheets rather than treating steel that cannot hold.
Asbestos roof encapsulation in Ely
A lot of the farm buildings around Ely carry corrugated asbestos cement roofs, and the duty to manage asbestos under the Control of Asbestos Regulations 2012 applies to those buildings whenever they are used for work. If your sheds have asbestos cement roofs, you are the dutyholder, and a feeling that the roof has been fine does not satisfy the regulations. Asbestos roof encapsulation cleans the roof under controlled conditions, repairs the fixings and flashings, then seals the surface with a flexible coating so the building is watertight and the fibres are locked in.
Encapsulation suits a working shed where the sheets are weathered but free of widespread cracks or holes, the frame and purlins are still solid, and the leaks are minor and traceable. It is the wrong answer where sheets have gone brittle, cracks have spread from the fixings across whole bays, or the structure has moved, and higher-risk materials such as asbestos insulation board need a licensed removal contractor instead. Even after coating it remains an asbestos roof: it stays on your register and your management duty continues, but the building keeps earning its keep.
Agricultural building coating in Ely
Drive a few minutes out of Ely and the land flattens into open fen, where big arable holdings run sizeable steel-clad stores alongside older fibre-cement barns with nothing to break the wind. It is usually the factory finish that goes first: faded plastisol, rust creeping out from cut edges and weeping fixings staining the sheets below.
Exposure alone does not condemn a roof, which is why commercial coating Ely agricultural buildings starts with a survey rather than a guess. An agricultural building coating is suitable where the frame is sound and the sheet has not corroded through, and preparation and the right system keep a store working for many more seasons.
The arable calendar rules the diary. Grain and vegetable stores fill from harvest and stay full for much of the time, so we schedule work for the quiet weeks each building has, agree vehicle movements at the start of the day, and protect any produce or wash-down areas that need it. Soft fen ground and the weight of access equipment are part of the survey too. Weathered but sound asbestos cement can often be cleaned and encapsulated; fragile, cracked or delaminated sheets are a different matter, and we say plainly when a roof needs replacing rather than coating.
Coat, repair or replace across Ely
Coating is not always the right call, and we would rather lose the work than seal up a roof or wall that should be replaced. The same principle guides every commercial coating Ely recommendation: localised damage on an otherwise sound surface points to a repair, widespread surface breakdown on structurally sound sheets is where coating earns its keep, and sheets that are holed, soft or failing at the fixings are usually telling you the covering is finished. The same logic applies to walls: hollow render, bridged damp-proof courses and structural cracking all need curing at the source before any decorative system goes on.
Our sequence is the same on every building. A physical inspection of substrate, seams, fixings, rooflights and drainage; a written report with photographs and a plain recommendation; and, only where a coating is right, a specification naming the system, the preparation and the detailing. The report is yours whatever you decide to do with it. On ground this exposed, advice based on readings rather than assumptions is the only kind worth having.
Recent projects from the same team
The work we bring to Ely is the same survey-led coating carried out elsewhere, and a few jobs of each type are written up in full. See our commercial wall coating case study, our industrial roof coating case study and our cut edge corrosion case study for the same standard we apply on fenland buildings.
Booking a coating survey in Ely
A survey is where every commercial coating Ely job begins, and it comes free and without obligation. We get up onto the roof or up to the wall, check the substrate, take the readings, and give you written findings with photographs before any figure is discussed. If the answer is that a coating is the wrong spend, that goes in the report too, so you can plan around accurate information rather than a sales pitch.
From Ely we cover the surrounding area comfortably, so a business with sites scattered across the fen edge can have them all assessed under one programme. Surveys here are commonly grouped with Cambridge, Newmarket, March and Thetford. For the wider picture across the county, see our Cambridgeshire coating hub, or get in touch to book a survey in Ely.

We survey before we recommend anything, and the recommendation goes in writing, including the times the answer is to repair or replace rather than coat.
Summer is the steadiest season for exterior coating: longer dry spells mean preparation, application and curing can be programmed with fewer weather delays.
All access and roof work is planned in line with HSE work-at-height guidance.
