The challenge with doors in Wicklow is not the door itself - modern uPVC profiles are inert, will not corrode, and carry a 12-year guarantee against fading and warping. The challenge is everything attached to the door: the multi-point locking gearbox, the hinges, the threshold strip, the handle, the letterplate. Those are steel and zinc components, and they are what the salt air on the Bray, Greystones and Arklow seafront will go after first.
The doors we replace most often on the East Wicklow coast are not 30-year-old timber - they are 12 to 18-year-old uPVC doors fitted in the 2008-2014 boom. The sash itself usually still looks fine. What has failed is the gearbox seizing because zinc has corroded, the cylinder snapping because the original was not 3-star rated, the hinges sagging because the steel pin has pitted, and the gasket perishing because UV and salt have worked through it. Replacing the door with a like-for-like spec just gives you the same problem in 2040.
That is why our default Wicklow coastal uPVC door spec is different from inland Dublin or Kildare. We fit a marine-grade stainless multi-point lock, powder-coated stainless hinges, an anti-snap TS007 3-star cylinder, and a thermally-broken aluminium threshold. The premium is roughly €120-€180 per door over a standard inland spec - a small price for hardware that does not need replacing in a decade.
Inland Wicklow is a different brief. Around Blessington, Newtownmountkennedy, Rathnew and Kilmacanogue, sheltered by the Wicklow Mountains, standard uPVC door hardware performs as well as it does anywhere else in Ireland. There the priority is U-value (heat loss through the back door is the typical complaint) and we recommend a triple-glazed glass cassette as the upgrade. We have been fitting doors across Bray, Greystones, Wicklow Town, Arklow, Delgany, Blessington, Newtownmountkennedy, Rathnew, Kilmacanogue and the smaller villages between them since 2003 - 23 years and counting, with over 5,247 homes completed across Dublin, Kildare and Wicklow.
