How long do uPVC and wooden windows last? Here's an honest comparison.
Timber windows look beautiful and have real character, but wood absorbs moisture — so it swells, warps, and eventually rots. It also needs regular painting or sealing to hold off that decay, and termites will target it.
uPVC absorbs almost no water, so it won't swell, warp, or rot. It needs no painting, and termites have no interest in it.
The honest framing: a well-maintained wooden window can last a long time — but 'well-maintained' means painting and sealing it for decades. uPVC reaches a similar life without asking anything of you.
uPVC lasts decades with no upkeep. Well-maintained timber can last too — but 'well-maintained' means painting and sealing it for decades. Neglected timber deteriorates quickly in this humidity.
Quality uPVC, well fabricated and fitted, lasts decades — with only occasional cleaning.
Moisture and neglect — swelling, rot, and termites, accelerated by missed repainting.
