Okay, full disclosure here, if you’ve just landed on this page straight from a search engine after googling “How much do replacement wood sash windows cost?”, you’ve landed on the blog of a company who makes and installs wood sash windows! It’s in our interests to sell you our sash windows, to extol the virtues of traditional wooden windows, of maintaining the period features of your beautiful Victorian home, of all the wonderful benefits of wooden windows etc. etc.

We usually receive a few calls about this time each year asking about ladybirds hiding around the frames of people’s windows. Are they safe? How can they be destroyed? How can they be prevented from coming back?

It’s a curious thing and worth a mention, especially at this time of year. Condensation on the outside of a double-glazed unit is actually a sign that your windows are working really effectively.

There are three places on a double-glazed unit you will potentially find condensation; on the inside face of the inner pane i.e. inside the room, inside the cavity between the two panes of glass, and on the outside face of the outer pane i.e. outside your house.
