Whether you’re facing Cleeve’s coastal damp or the chill of winter, our windows stay strong, secure, and effective year after year. Your new windows will last longer and stay looking perfect with only minimal maintenance, only needing a quick wipe down every once in a while.

Frequently Asked Questions

Can I expect to save energy with my new uPVC windows?
This is dependent on the uPVC Windows you previously had, but in most situations, yes! If you upgrade from single to double or double to triple glazing, you will undoubtedly notice a difference in the amount of money you spend on heating throughout the winter. If the uPVC Windows you’re replacing are rather old, the seal in their frames may not be as effective, allowing draughts to enter and further diminishing the effectiveness of your uPVC Windows.
Installing brand new, skillfully fitted double or triple glazing uPVC Windows is likely to result in energy savings, but you’ll notice the difference most sharply if you are upgrading from single glazing.
What sort of glazing should I get?
Most window suppliers provide double glazing as standard, but not all double glazing is made equal. We discovered that a 28mm unit with a 20mm gap between the panes is the most energy efficient and noise-reducing, thus we offer it in all of our double glazed uPVC Windows. Single glazing is inefficient and produces condensation; it is rarely used in new construction.
If you live in a cold climate and want the maximum thermal efficiency available, call us to discuss triple glazing; with three panes of glass and two gaps, it is perfect for exposed rural buildings.
Is there a guarantee?
Our items come with a written guarantee that lasts up to ten years. This implies that we are as committed to providing you with high-quality items as you are to receiving them. The warranty may be for ten years, but the majority of them will survive considerably longer if properly cared for. When we install, we’ll discuss the best approach to maintain them.
