Composite doors in Carn Brea, installed professionally.

Carn Brea village and the terraces that climb the hillside under the monument sit about as exposed as housing gets in this part of Cornwall. There's very little to break the wind once you're above the main road, and anyone who's lived up there a winter or two knows exactly what that means for a front door: draughts finding their way through gaps that never used to be there, paint peeling off the exposed side, and old timber doors that swell shut in the wet and then won't sit flush once it dries out again.

Composite doors handle that exposure better than almost anything else on the market, mainly because the insulated core doesn't move the way solid timber does with moisture and temperature swings. We've fitted enough doors up around Church Coombe and the streets nearer the Piece side of the hill to know that a well-fitted composite door with a decent multi-point lock will sit flush and seal properly through a full Cornish winter without the yearly adjustment that timber doors need.

The height and openness of the site also means rain tends to come in sideways rather than straight down, so we pay close attention to drip bars and weather seals on every job up here, not just the door itself. It's a small detail but it's the difference between a door that stays dry inside the frame and one that lets damp creep into the brickwork behind the architrave over a few winters.

None of this changes our pricing, it's just part of doing the job properly on ground this exposed. We'd rather spend the extra twenty minutes getting the seals right on site than have someone ringing us in January about a draught.

The rows of miners' terraces below the Carn Brea monument are some of the most characterful housing in the area, and also some of the most consistent in terms of door openings, since a lot of them were built to the same pattern by the same builders in the same few decades. That's actually good news for fitting, because once we've done one or two doors on a street we've usually got a decent idea what we're dealing with for the rest.

That said, a hundred and fifty years of individual alterations means no two houses on the same row are quite identical anymore. Porches have been added, some houses have had their door openings widened slightly for accessibility, others have been left completely original. We always survey each property individually rather than assuming the neighbour's job tells us everything we need to know, because it's the small differences, a slightly out-of-true reveal or a different step height, that catch people out.

A lot of these terraces sit directly onto the street with no front garden to speak of, which means the door is genuinely the first thing anyone sees of the house and also takes the full brunt of passing traffic spray in wet weather. We tend to recommend a slightly more robust bottom rail detail and a durable foil finish for these properties, since they see more day-to-day wear than a door set back behind a garden gate.

Parking for the fitting van can be tight on some of the narrower terraced streets, so we'll always check that with you when booking rather than turning up and hoping for the best. It's a small thing but it keeps the day running smoothly for everyone on the street, not just the customer.

Above the main village, toward the open ground near the Beacon and the properties that back onto Carn Brea's higher slopes, the exposure steps up again. These houses catch weather from several directions at once, and we see doors here that have genuinely struggled, not through poor original build quality but simply because nothing short of a well-sealed composite door copes indefinitely with that kind of battering.

For these properties we generally recommend the full specification: a drainage threshold rather than a standard cill, the heavier-duty weather seal option, and we're careful about hinge selection too, since wind loading on a door in an exposed position is a genuine consideration over years of use rather than a one-off gust. None of this pushes the job outside our usual price bracket, but it does mean the survey for a higher-ground property takes a bit longer, because we're checking things a sheltered terrace wouldn't need us to check.

We also find that render and pointing around door openings on these more exposed houses has often taken a battering over the years, so it's common to need a bit of making good around the frame before or after fitting. We'll flag this at survey stage rather than leave it as a surprise, and we can usually recommend making good ourselves or point you to someone local who does it well if it's beyond what we'd normally include.

It sounds like a lot of extra consideration for what's still just a front door, but Carn Brea's higher ground isn't a place where a bargain-basement fit lasts, and we'd rather do it right once than have someone back on the phone to us in three years.

Carn Brea's housing splits fairly cleanly into two types: the granite and stone-built terraces from the mining era, and the more modern housing that's filled in around Carnkie and toward Barncoose over the last few decades. For the older terraces, we see a strong preference for darker, more traditional colours, anthracite grey especially, along with the deeper green and blue shades from the Endurance range, since they suit the stone and don't look out of place on a row where several houses might still have their original slate roofs.

On the newer estates, there's more appetite for lighter colours and cleaner glazed designs, since these properties don't carry the same weight of matching a historic street. We do a fair number of white and cream composite doors with simple glazing on these newer streets, often alongside matching porches or canopies that have been added more recently.

One thing that comes up a lot on the terraced streets is customers wanting to keep a similar look to what was there before, particularly if the house has had the same style of door for a long time and neighbours still have the original design either side. We can usually source something close in the composite range without it being a slavish copy, which tends to satisfy both the desire for continuity and the practical benefits of switching away from old timber.

Whatever the street, we bring physical samples to survey. Light on that hillside changes quickly with the weather rolling in off the north coast, and a colour that looks one way in bright sun looks quite different under cloud, so it's worth seeing the actual material rather than a printed swatch.

Carn Brea's mix of dense terraces and more scattered housing higher up means security considerations vary house to house. On the terraced streets, doors open more or less straight onto the pavement, so a door's resistance to forced entry matters in a very direct, practical way, there's no garden or gate slowing anyone down first. Every composite door we fit here comes with 3-star anti-snap cylinders and multi-point locking as standard, tested to PAS24, which addresses the two most common methods used against poorly secured older doors: cylinder snapping and simply forcing a weak lock mechanism.

Higher up the hill, where properties are more spread out and some back onto open land near the monument itself, isolation is more the concern than direct street access. We find customers here often ask about additional hardware like door chains or spy holes alongside the main door spec, which we're happy to fit as part of the job.

We don't upsell security as an add-on because, frankly, it isn't one, it's built into every composite door we supply regardless of budget or street. The £1,395 entry point and the £2,895 premium end both come with the same locking standard; the difference between them is glazing, colour range and hardware finish, not how secure the door actually is.

For anyone particularly concerned, we're happy to talk through the specific lock mechanism and cylinder rating on survey, and show you the difference between what we fit as standard and the kind of older euro-cylinder locks that are still common on unreplaced doors in the older parts of the village.

Our Certass registration means every door we fit in Carn Brea is self-certified against current Building Regulations without needing separate local authority sign-off, and we provide that documentation as standard once the job's complete. It's worth keeping safe, particularly if you're planning to sell in the coming years, since buyers' solicitors do ask for it.

The 10-year guarantee covers the door panel, frame and hardware against manufacturing or fitting defects, including issues like warping, seal failure or lock mechanism faults. On a site as exposed as Carn Brea, that guarantee earns its keep more than most, since any weakness in materials or fitting tends to show itself within the first couple of winters rather than sitting dormant for years, and we stand behind the work for the full decade regardless.

After fitting, we leave customers with basic care guidance, mainly around keeping drainage channels in the cill clear of debris, since leaves and grit blow about a fair bit up on the hillside and can build up in the threshold if never checked. It takes thirty seconds occasionally and it keeps the drainage doing its job properly.

If anything does go wrong within the guarantee period, we come back out. We're a local outfit working this patch regularly, not a national fitter who's moved on to the next region, so a callback isn't a special favour, it's just how the job's meant to work.

Given how much door openings and exposure vary between a terraced street under the monument and a house higher up toward the Beacon, we always survey in person rather than quoting from photos. It usually takes less than half an hour and means the price we give you on the day is the price you pay, with no surprises added once fitting starts.

During the survey we measure the opening, check the condition of the existing frame, discuss colour and glazing with physical samples, and for higher-ground or particularly exposed properties, talk through whether the fuller weather-sealing specification makes sense for your situation. We'll also check parking and access for the fitting team, which matters more on some of the narrower terraced streets than it might elsewhere.

Fitted prices across Carn Brea generally run from £1,395 for a straightforward solid door on a standard terraced opening, up to £2,895 for a fully glazed door with premium hardware and the enhanced weather-sealing spec that suits the more exposed higher-ground properties. Most terraced jobs land in the lower-to-middle part of that range; most higher-ground jobs land in the middle-to-upper part, simply because of the extra specification involved.

If you're getting in touch, it helps to mention roughly whereabouts on the hill your property sits, since it gives us a decent idea of what we're likely to be dealing with before we've even booked the survey in.
