About Us

You may think that your sash windows are beyond repair, however traditional sash windows are an essential feature of a period building's character and therefore, it is vital to retain them.

This is not only because of the aesthetic appeal, but because they add value to your property. At Smooth Movement Sashes we will be able to undertake all types of repair work that will restore the windows back to their original condition.

We Can Install Double Glazing on Existing Box Frames

We also can install new double glazed units to existing box frames or we can replace the new box frame and sashes. Our renovation system will eliminate all common problems associated with sash windows, e,g rattles, draughts, broken cords and sticking sashes. We can fit our draught-proofing system to your original windows and this will provide effective insulation therefore drastically reducing your energy costs. As standard, this system significantly reduces noise penetration, however we can fit if required, acoustic glass to further enhance this. You can also save money and keep warm with new double-glazed sash window.
