Cladding spraying in Portsmouth
Few places in England test a coated steel building like Portsmouth. Most of the city sits on an island, the sea is never far away, and salt spray reaches cladding that would weather far more slowly inland. Cladding spraying counters that exposure: the existing panels are cleaned, repaired and resprayed on site with a coating system chosen for the conditions, at a fraction of recladding cost.
We are survey-led, and in a marine environment that is not a sales line. The state of the cut edges and the adhesion of the old finish decide what the job is, and neither can be judged from the road.
What marine exposure does, and where we look for it
Salt accelerates everything corrosion does. On survey we pay particular attention to:
- Cut edge corrosion at sheet ends, laps and around openings
- Rust staining and blistering low on seaward-facing elevations
- White rust on galvanised flashings, gutters and trims
- Chalking and heavy fade on the sun-and-salt face of the building
- Sealant joints and fixings that have given up early
Caught while the corrosion is still at the edges, all of this is treatable, and treating it properly is most of what separates a lasting respray from a cosmetic one. The colour is the last five per cent of the job; the preparation is the rest. Once the new finish is on, an annual wash-down to shift salt deposits is the single cheapest thing an owner can do to help it last.
From survey to finished elevation
The inspection produces a written scope: which panels need replacing, where edges need mechanical preparation and sealing, what each elevation needs by way of cleaning and priming, and which coating system suits both the substrate and the exposure. Pricing follows the report. Work is then phased so the premises keep operating, with masking protecting glazing, signage and anything parked nearby. Roller shutters, doors, fascias and gutter lines are usually included in the same scope, so the finished building reads as a whole rather than a fresh wall above tired trims.
We survey and spray across Portsmouth and the surrounding Hampshire towns, including Gosport, Fareham, Havant and over to Southampton, so buildings either side of the harbour are equally reachable.
System choice carries more weight here than inland. The specification has to suit a salt-laden environment as well as the substrate, and on tight urban sites the plan also has to deal with neighbouring buildings, parked cars and pavements within masking distance. Both questions get answered at survey stage, in writing, before a price is attached to anything.
The point where we advise replacement instead
Marine exposure means more buildings here reach the point of no return than inland, and it would be dishonest to pretend otherwise. Perforated sheets, composite panels with wet or delaminating cores, and elevations where fixings have failed wholesale are beyond coating. Where the survey finds that, the report says replacement, sometimes for a few panels, sometimes for more, and we explain the reasoning rather than spray over the evidence. A coating earns its keep on sound steel; on failed steel it just postpones the bill and adds our invoice to it.
Choosing a contractor who inspects before pricing
Any sprayer can quote a rate per square metre. A survey-led contractor tells you whether your building should be sprayed at all, what has to happen first, and what the finished system needs to withstand on this stretch of coast. For a clad building in Portsmouth, that inspection is the cheapest decision-making tool available before any money goes on the exterior, and the written report is yours to keep whichever way you decide.
