Frequently Asked Questions
How long do uPVC windows last?
Quality uPVC windows typically last 20–25 years. They won't warp, rot, or rust and require minimal maintenance beyond occasional cleaning.
Can uPVC windows be painted?
Yes — using specialist uPVC spray paint. However, this typically costs £50–£100 per window and needs re-doing every few years. Buying in your desired colour from the outset is better value.
Are uPVC windows energy efficient?
Modern A-rated uPVC windows with low-E glass and argon gas fill are highly energy efficient. They can reduce heat loss through windows by up to 50% vs. single glazing.
What colours can uPVC windows come in?
White is the classic and cheapest option. Anthracite grey, black, cream, rosewood, and woodgrain finishes are popular alternatives. Dual-colour (white inside, coloured outside) is also available.
