The work in your house

Your property will always be secure, the existing windows that are being renovated/draught-proofed are reinstalled, or the new windows are installed and secure by the afternoon.

The majority of our work is carried out from the inside, as sashes are removed internally from a box-frame window.

Your house will be protected with dust sheets throughout from your entrance door to the rooms where work is occurring. It will be regularly cleared during the work and at the end of each day.

Our work ethic and staff:

Oxford Sash Windows work ethic is to do the best and most effective work possible, in the most efficient way, and with the least disruption to you - we are now past masters at this.

Oxford Sash Window staff are skilled, neat, tidy and efficient.

The main Oxford Sash Window craftsmen have been with the company since we started and have now faced any possible challenges, so you are in safe hands.

Oxford Sash Window staff are not paid by the amount of work they complete in a day or a week, i.e. ‘piece work’ – this is skilled work and piece work can lead to a culture of cutting corners and the focus of the work being on the money earned (e.g. equalling the number of windows draught-proofed or installed), rather than on the quality of the work itself, - we don’t work slowly but the work we do requires skill, attention to detail, and making sure it is done correctly, this leads to pride in the work completed and to job satisfaction.
