What Our Customers Are Saying
Frequently Asked Questions
Get answers to common questions about our wooden sash windows, from their customisation and installation to maintenance and heritage compliance.
What does a flush window mean?
A flush window is designed to have the opening sit perfectly flat and level with the surrounding frame, creating sleek lines and a clean, elegant look. These windows are increasingly popular in modern homes where homeowners appreciate the smooth, minimalist aesthetic they offer. In contrast, a storm sash window features a sash that overlaps the frame, providing enhanced protection from severe weather conditions.
Do flush casement windows cost more?
The cost of flush casement windows varies depending on the finishes and colours you select. However, the price difference between flush casement windows and traditional casement windows is generally minimal. With a wide range of options available, you can tailor the windows to suit either a traditional or modern style.
Which colours can I choose from?
At Everest, we offer a stunning selection of colours and natural woodgrain finishes, ensuring the perfect match for every property. Our colour range includes the classic white uPVC finish, elegant Sage Green, and modern shades like smooth anthracite grey or sleek black. For a contemporary touch, you can also choose dual colours to complement both the interior and exterior of your home.
