Full Sash Window Renewal Service

We have found that we need to work on 4 sash windows for our service to be cost effective. For work on fewer windows we need to quote accordingly.

Our set up costs mean it is not possible to visit homes to conduct small repairs on individual windows, but we suggest you consider giving your windows a new lease of life with our complete Sash Window Renewal System.

You’ll be amazed at the difference.

Now operating in and around Hobart and Melbourne.
