Composite doors in Portscatho, installed professionally.

Portscatho looks, at first glance, like it might present the same problems as a Lizard cove — a cluster of cottages tumbling down toward a small working harbour, boats pulled up on the beach, narrow streets. And there are real similarities in the fitting logistics. But the weather the two places actually experience is genuinely different. Portscatho and the Roseland coast face east and south-east across the more sheltered water of the Fal estuary approach rather than directly into the open Atlantic, and the peninsula itself takes some of the worst of the prevailing south-westerlies before they reach here. It's still a coastal village that needs a properly specified door — this isn't a soft option — but it's a different brief to Mullion Cove or Cadgwith.

What we see in practice: genuine but moderate salt exposure, decent but not extreme wind loading, and a building stock that's had time to weather gently rather than being hammered. Composite is still comfortably the right material — nothing else offers the same combination of low maintenance and weather resistance without ongoing painting and re-hanging — but we don't need to go to the fullest storm-grade specification as standard here.

The practical challenge in Portscatho is almost entirely about access rather than weather. The streets around the harbour are narrow, and in season the village fills with visitors, boats get trailered through, and parking for a work van close to a harbourside cottage can be genuinely difficult. We plan installs here around quieter hours where possible, and for cottages right on the front we sometimes carry materials the final stretch by hand rather than trying to park immediately outside.

The cottages themselves are a good mix — old fishermen's terraces close to the water, slightly larger Victorian and Edwardian houses set back a little, and a scattering of newer infill on the edges of the village. We template every one individually, as the older harbourside cottages in particular rarely have a perfectly square aperture, having settled and shifted gently over a couple of centuries.

Gerrans sits just up the hill from Portscatho and technically shares a parish council, but it's a touch more sheltered by virtue of sitting back from the immediate harbour frontage. Properties here tend to be a straightforward mix of Cornish stone cottages and mid-century housing, and installs are generally more straightforward logistically than the harbour itself — easier parking, more standard apertures, less need for hand-carrying materials.

We still specify a proper coastal-grade fixing set here as standard, because 'a touch more sheltered' doesn't mean inland — Gerrans is still well within reach of salt-laden air off the Roseland coast, and it would be a false economy to drop the fixings spec purely because the postcode isn't right on the water.

The stretch of coast either side of Portscatho — Porthcurnick and Towan Beach in particular — has a scattering of standalone properties with a much more direct relationship to the sea than the sheltered harbour itself. These get the step up in specification that any genuinely coastal property deserves: A4 stainless fixings, a proper drainable threshold, a compression seal set for the tighter closure profile. It's not the fullest Lizard-grade spec, but it's a clear notch above what we'd fit for a property tucked into the village a few streets back from the water.

A number of these are holiday properties, and the same practical considerations we mention elsewhere on the Roseland apply here too — keyless or smart-lock entry is worth the modest extra cost if a letting agent or cleaning team is managing access without the owner present.

Portscatho's palette leans traditional — white and cream-rendered cottages dominate right around the harbour, with the occasional bold splash of colour on a fisherman's cottage door that's clearly been chosen to stand out in harbour photographs for generations before ours. Off-White, Cream and Chartwell Green are the most common orders here, and we occasionally fit a proper bold colour — Poppy Red particularly — on a harbourside cottage where the owner wants their door to be the one people remember.

Further up in Gerrans and the more standard housing stock inland, the range widens out to include Anthracite Grey and Painswick on the newer properties, much as you'd expect anywhere else in Cornwall.

For harbour properties, we schedule around the quieter parts of the day and season where we can, and materials often go the final stretch by hand rather than by van. Removal, templating, frame fitting, slab hanging and a full doorstep handover still complete within a single working day, much as anywhere else — the timeline doesn't change, just the logistics of getting there.

For Gerrans and the properties set back from the immediate harbour, access is generally no different to any small Cornish village, and installs run to a standard schedule without any particular complication. Either way, every job finishes with the same handover: spec sheet, 10-year written guarantee and cylinder security card talked through on the doorstep before we leave.

Every door we fit around Portscatho, whether in the sheltered village centre or on the more exposed stretch toward Porthcurnick, comes with a full 10-year guarantee, a spec sheet detailing the exact fixings and glazing used, and a cylinder security card confirming the 3-star anti-snap rating. This is worth keeping on file regardless of whether you're the resident owner, a landlord, or managing the property as a holiday let, since insurers and future buyers alike may ask for it.

We're also happy to talk through the specification differences between a harbour cottage and a coastal-fringe property in plain terms at survey, so you understand exactly what you're paying for and why — rather than a generic 'coastal upgrade' line that doesn't explain what's actually different about the door.
