Composite doors in Pendeen, installed professionally.

Pendeen grew up around tin and copper mining, and the housing stock still shows it — tight rows of granite cottages built for mine workers, thick-walled and low-ceilinged, with door openings that were never cut to a standard modern size. Templating matters more here than almost anywhere else on our patch, because the aperture in a Pendeen cottage might be out of square by a genuine centimetre or more after 150 years of settlement, and a stock-size door simply won't seat properly against stonework like that.

We measure every Pendeen aperture on-site rather than working from a rough estimate, checking for bow in the lintel and any settlement in the sub-frame before quoting. The upside of granite construction is that once a door is properly fitted and sealed against it, it stays put — granite doesn't move seasonally the way timber-framed or rendered block construction can, so the fit we achieve on day one tends to hold for the life of the door.

Pendeen sits directly on the north coast with nothing between the village and the Atlantic but Pendeen Watch lighthouse and a stretch of exposed cliff. This isn't a village that gets occasional sea spray on a bad day — it's routine weather. We've stripped enough failed doors off Pendeen cottages to know exactly what happens without the right spec: zinc-plated hinges rust solid within two winters, standard uPVC skins go brittle and discoloured within five years, and softwood swells and splits from constant saturation.

The Pendeen specification, as standard, is A4 stainless steel fixings throughout — hinges, keeps, screws, lock body — because anything less corrodes visibly within a season out here. The threshold is drainable stainless-clad to shed wind-driven rain that comes in near-horizontal off the cliffs in a north-westerly, and the compression seal runs on a triple-brush upstand that copes with the salt crust that builds up on anything left exposed. None of this is an upgrade tier; it's what a Pendeen front door needs to still be doing its job in year ten.

Several Pendeen properties sit close to Geevor Tin Mine and the Levant engine houses, both of which carry World Heritage status as part of the Cornish Mining Landscape, and understandably a lot of nearby residents assume that means restrictions on what they can do to their own front door. In practice, unless your specific property carries a listed-building designation, a straightforward composite door replacement doesn't need any special consent — the heritage protection sits on the mine buildings and the wider landscape designation, not on ordinary cottages nearby.

That said, we do take extra care with colour and glazing choice for properties directly overlooking the mine sites, simply because a jarring modern colour looks out of place against that backdrop. Heritage panel styles in Racing Green, Chartwell Green or a weathered-looking Cream do the job of respecting the setting without any regulatory pressure to do so.

The light out here is unusually flat and grey for a lot of the year, punctuated by very bright, very harsh sun in summer that bleaches cheap colour finishes fast. We've found Anthracite Grey and Slate Grey hold their tone best in both conditions, which is a large part of why they're the most-ordered colours in the village. Chartwell Green does well against the granite too, particularly on the older terraced cottages toward Boscaswell.

We'd steer most Pendeen customers away from very pale colours like true white, simply because the constant salt-laden drizzle shows up as streaking faster on white than on a mid-tone grey or green — it's not that white doesn't work, it's that it needs cleaning more often to look its best, and most people out here would rather not add that to the list.

Pendeen isn't a high-crime area, but it is a village with a fair number of holiday cottages and second homes that stand empty for stretches, particularly out of season, and empty properties are exactly what opportunist thieves look for. Every composite door we fit — whether it's a full-time residence or a holiday let — comes with PAS24 testing and a 3-star anti-snap cylinder as standard, closing off the two most common forced-entry methods without any need to specify an upgrade.

For holiday-let owners managing changeovers remotely, we'd also point to keyless entry as a genuinely practical addition here rather than a gimmick — it removes the need to courier keys or rely on a lockbox bolted to an exposed granite wall, which itself becomes a target.

Pendeen's streets are narrow in places, particularly around the square and the older terraces, so we plan parking and access at survey stage rather than guessing on the day. Once the van's in position, the process runs the same as anywhere: dust sheets down, old door and frame out within the first hour, new frame templated and bedded on butyl tape and low-expansion foam — taking whatever time the granite aperture demands rather than rushing a poor fit.

Slab, hardware and multi-point lock go in next, threshold weathered, trims finished, and we test the lock action repeatedly before signing off. Given the exposure here, we also walk through basic seasonal care on handover — mainly just a reminder to hose down salt residue occasionally rather than letting it build up on the hardware.

Even with the full marine specification fitted as standard, a Pendeen door benefits from a bit more routine attention than one fitted further inland, simply because of the sheer volume of salt-laden air it's dealing with. We'd recommend hosing down or wiping the slab and, in particular, the hardware — hinges, handle, letterplate, cylinder surround — every month or so through the winter storm season, when salt crust builds up fastest. It takes five minutes and it's the single biggest thing you can do to keep the A4 stainless fixings looking and performing as they should.

The compression seal and multi-point lock benefit from an occasional light silicone lubricant application too, particularly given how hard the seal is working against sustained wind-driven rain for a large part of the Pendeen year. We leave a maintenance card at every handover covering exactly this routine, plus the ten-year written guarantee and cylinder security card.

If a door ever starts to feel stiff or the lock needs more effort than usual to engage, we'd rather you called us early. Out here, a hinge or seal issue left unaddressed tends to get worse fast given the exposure, whereas caught early it's usually a very quick adjustment on a callback visit.
