Falmouth Composite Doors: Built for Salt Air on Every Street
By Cornwall Composite Doors · 24 August 1969 · 4 min read
From harbourside terraces to cliff-top homes, Falmouth's salt exposure is relentless — here's the specification we use across the whole town.
A town where salt air reaches every property
Falmouth's position on a natural harbour means salt-laden air reaches well beyond the immediate waterfront — Pendennis, Gyllyngvase and the terraces climbing up from the docks all see meaningfully more corrosive exposure than an equivalent inland town. We specify every Falmouth installation with that in mind by default, rather than only on the streets closest to the water.
Why timber struggles here specifically
We remove a lot of failed timber doors in Falmouth, and the pattern is consistent: paint that's blistered and lifted within a couple of years, joints that have opened up as the timber has moved with damp, and ironmongery that's corroded even when it's stainless-plated rather than solid stainless. A composite doorset's GRP skin doesn't absorb moisture the way timber does, which removes the root cause of most of that failure.
Harbourside terraces versus Pendennis-side homes
Falmouth's older harbourside terraces call for traditional or cottage-style composite doors with heritage colours — Chartwell Green and Duck Egg Blue in particular suit the granite and rendered fronts near the docks. Toward Pendennis and the newer housing further out, contemporary flush styles in Anthracite Grey are more common, generally matching existing modern window schemes.
What we change specifically for Falmouth's exposure
Stainless hinges and fixings throughout, uprated weatherseals, and a full drainage detail through the cill are standard on every Falmouth job — the same specification we'd use in any seriously exposed Cornish coastal town, because Falmouth's exposure genuinely justifies it.
