Across Almada, Cova da Piedade, Pragal and Cacilhas, 89% of homes predate 1991 (2021 Census) — nearly half from the 1961-80 wave alone. Original thin aluminium or wood frames: cold rooms, draughts and condensation in the morning.
47% of the homes on the Costa are second residences (2021 Census) — in the whole metropolitan area, only the town of Sesimbra has more. A house closed up for the week or the whole off-season, with salt air at work, needs windows that seal, tilt to ventilate, and don't corrode.
72% of homes in Laranjeiro and Feijó predate 1991, 40% from 1961-80 alone. These are the buildings of people who cross the bridge to Lisbon every day — and want to come home to a warm, quiet house and a lower bill at the end of the month.
On the Atlantic front, salt and wind eat through wood and poorly-treated aluminium in a few years. PVC doesn't corrode, never needs repainting and takes the exposure — the right material for the seafront.

The building is from 1972 and the windows are the originals. In winter the glass runs with water and mould grows in the bedroom corner.
PVC with double Low-E glazing and new sealing. The glass stopped condensing and the mould never came back.
Chat on WhatsAppI moved here for the ocean, but the flat is closed while I travel and it always smelled damp when I got back.
PVC windows that seal properly and tilt to ventilate safely. The flat stays dry even after weeks away.
Chat on WhatsAppI live in a single-storey house and the old window locks were clearly the weakest point of the place.
She didn't want bars or an extra alarm. Asked about the RC2 rating, confirmed the hardware met it, and felt at ease leaving the house empty during the day.
Chat on WhatsAppWe leave at 7 to catch the bridge and get back at 7. The house was always cold when we walked in.
Double Low-E glazing throughout. The morning's warmth is still there at the end of the day, and the heater became the exception.

For a typical 2-bedroom flat in Cova da Piedade, Laranjeiro or Feijó, a full replacement usually comes to between €1,800 and €3,200, with fitting, removal of the old frames and warranty included. Get an estimate with the calculator in a minute, no contact details needed.
It's the case where it shows most. A closed-up house with draughty frames picks up damp, mould and a stale smell; windows that seal properly stop that, and the tilt position lets you ventilate safely. You arrive at the Costa to a dry house that's ready — instead of one that needs a week of airing.
Branded PVC doesn't. The profiles we install (Veka, Rehau, Kömmerling) have UV protection through the body of the profile and class-A wall thickness — they don't yellow or warp with sun exposure, and salt doesn't corrode them. It's wood and cheap coated aluminium that suffer on the Atlantic front.
The municipality is in winter climate zone I1, with a maximum Uw of 2.80 W/m²·°C (Decree-Law 101-D/2020 and Portaria 138-I/2021). Our PVC windows with double Low-E glazing sit well below that value.
We book the measurement for the end of the day or on a Saturday, at your convenience — a good part of Almada works across the bridge and we plan for it. Fitting usually takes a single day per home, arranged in advance so you only need to open the door once.
