Cladding spraying in Durham
Durham’s postcard image is the cathedral on its peninsula, but most of the county’s working buildings are steel-clad and strictly practical. Cladding spraying in Durham serves that working stock: units on the business parks around the city, industrial buildings in the former colliery towns, agricultural sheds towards the upland fringe, and the trade and retail space along the A1 corridor. County Durham weather is not gentle with any of them: cold, wet and frequently windy, with salt influence drifting in from the coast to the east.
National Coating Specialists works survey-led. We establish the condition of the cladding before we recommend anything, because the condition is what decides whether coating makes sense.
Signs a clad building here is due attention
The North East climate produces a familiar pattern of wear, and most of it is visible if you know where to look:
- Colour fade and chalking, worst on the most exposed elevations
- Orange staining at sheet ends and laps, the start of cut edge corrosion
- Green algal growth on shaded, north-facing faces
- Streaking beneath gutters, fixings and flashings
- Patch repairs and replacement sheets that no longer match the rest
None of these automatically mean replacement. Most are exactly what spray refurbishment exists for, provided the substrate underneath is still sound, and establishing that is the survey’s job.
Aspect and altitude matter here too. A building on an exposed ridge above the Wear weathers differently from one tucked into a valley estate, and the survey records those differences rather than treating every elevation as if it faced the same sky.
How we run a survey-led project
The inspection comes first: adhesion testing, corrosion mapping at cut edges, laps and gutter lines, and a close look at fixings, sealants and flashings. The report that follows is written in plain English and tells you whether coating is worthwhile. If it is, the building is washed down, corrosion treated, bare metal primed and everything else masked before the new finish is sprayed in even coats. Weather windows are planned realistically; this is the North East, and we schedule accordingly. Access equipment is matched to the building, from towers on small units to powered access on taller elevations.
We are based in the South East and work nationally. Survey trips to Durham routinely take in Chester-le-Street, Sunderland, Darlington and Newcastle upon Tyne, so portfolios spread across the region can be assessed together.
The cases where we advise against coating
A coating is the right answer surprisingly often, but not always. Wholesale delamination of the factory finish, corrosion that has gone through the sheet, loose or distorted panels and active water ingress all rule it out until they are dealt with. We will not spray over any of them, and our report will tell you why. Fire performance is the other hard limit: no paint changes it, and anyone who implies otherwise is selling rather than advising.
Why inspect before you spend
Every pound in a coating project sits on top of the survey’s findings. Get the inspection right and the preparation, primer and finish all follow logically; skip it and you are gambling on whatever is under the old paint.
For owners and facilities managers across Durham and the wider county, survey-led means the recommendation is driven by the building’s condition, not the contractor’s order book. That is the standard we hold ourselves to on every project, large or small, and it is the right first question to ask anyone you invite to look at your cladding. If a building you look after is showing the signs listed above, an inspection will settle what they actually mean.
