How do you maintain wood-effect uPVC windows? The answer is refreshingly short.
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.
That's the whole routine — and it's the entire point. A wood-effect uPVC window gives you the timber look while asking for none of timber's annual painting and sealing.
Wipe with mild soapy water, keep tracks and drainage clear, and lightly lubricate the hardware occasionally. No painting, staining, sealing, or rot treatment — ever.
No — unlike real timber, the finish is part of the profile. There's nothing to re-apply.
Quality UV-stable finishes resist fading well.
