Sash style sliders that suit a period frontage without the draughts that come with the originals.
Vertical sliders cost more than a standard casement of the same size, and that is down to the mechanism. A sash window has balances, guides and two moving sashes to make and set up, so there is more in it than a hinged window. Size, the bar layout on the glass and the finish all move the price from there. Astragal bars and a woodgrain finish look right on a period frontage and add to the cost.
We survey each opening free of charge and price it in writing, including the window, delivery, fitting, sealing and the making good. If your property is listed or sits in a conservation area, tell us at the survey, because what is allowed varies and it is better dealt with before anything is ordered.
Larger sashes need heavier balances, and a triple sash arrangement is more work to make and set up than a standard pair.
Plain glass is the cheapest. Georgian or astragal bars look right on a period house and add to the price per window.
White is the value option. Woodgrain and heritage colours cost more and are usually what makes the window look correct on an older frontage.
Old timber sash boxes often hide rot or movement. We check at the survey and tell you what putting it right involves.
Sliders take a little more setting up than a casement, and that is time well spent. Here is the process.
We measure each opening, look at the existing box and cill for rot or movement, and go through bar layouts and finishes against the rest of the frontage so the windows look right rather than nearly right.
One written figure covering the windows, delivery, fitting, sealing and making good, with each opening priced so you can see the detail.
Sliders are made to your surveyed sizes with the balances set for the weight of the sashes. We confirm the lead time in writing. Delivery is free.
Old window out, new frame packed and fixed, then the sashes hung and the balances adjusted until they run smoothly and hold at any height. We take the old frames away and make good inside and out.
That depends on the details, which is why we go through them at the survey. Bar layout, the depth of the cill and the finish are what make a modern slider read correctly on an older frontage, and getting one of them wrong is what makes a replacement look off.
On the sliders we fit, yes. Both sashes tilt inwards so you can clean the outside from inside the room, which matters on a first floor bay where the alternative is a ladder.
No. The originals were draughty because timber moves and the sashes ran loose in the box. A modern slider runs on balances with brush and gasket seals all round, so it keeps the look without the cold.
Often, but the rules vary and sometimes the council has a view on materials and bar layout. Tell us at the survey and we will work to what is permitted rather than ordering something that has to come back out.
Ten years on the entire window, which on a slider includes the balances and the running gear as well as the frame and the sealed units. The moving parts are the ones that need covering.
