Sash Windows

James Oliver’s Sash windows can be recognised instantly by their grid designs and are usually made up of a grid of smaller glass panes joined with bars.

Georgian-style houses can often be associated with ‘six over six’ or ‘eight over eight’ grids whereas Victorian homes usually have a ‘two over two’ pattern. We are a family-owned business with over 30 years of experience providing homeowners in and around the Lincolnshire and East Midlands region with quality sash windows. Proud of our local reputation, we do everything we can to provide excellent customer service and the best sash windows in Lincolnshire.



You must take a measured approach when buying new windows...

New windows shouldn’t be bought until you are fully content that they will sustain the original character of your house and won’t in any way spoil its appearance. Your purpose for replacing your windows could be down to a series of factors, including the necessity to shut out draughts and improve thermal standards. If you inform our window consultants of the motives behind the move, they will suggest appropriate replacement window solutions.

Functionality - A sash window is a design renowned for its versatility. James Oliver also has a window collection containing windows that open from the side or top, vertically slide and tilt and turn. If you pay a visit to our showroom, you will be invited to try out the differing functionalities of our window styles, so that you can uncover a favourite. Our window consultants are also happy to assist.

Guarantee - Our comprehensive 10 Year Guarantee offers you complete value for money and, crucially, a lifetime of reassurance. We’re able to offer such a guarantee because our sash windows are designed and manufactured to remain perfectly functional and completely fit for purpose for at least 10 years. Materials and components have been selected for their inherent durability and our manufacturing processes are second to none.
