Our Process
A standard sized sash window will take about 2 hours to draught proof. At the time of booking please let us know the rough height and width dimensions of each window in order to ensure we arrive with enough draught proofing material. See the diagram alongside for the dimensions we need.
The draught proofing process:
- The lower sash is removed from the frame. A groove is routed into the meeting rail (where the two sashes meet in the closed position) a brush pile and carrier is fitted into the groove.
- The existing parting beads are removed and replaced with new parting beads that contain a draught proofing brush pile.
- A hard wearing compressible seal is added to the top of the top sash and to the bottom of the lower sash.
- The window is then reassembled. Any disturbance we have made to the decoration is made good.
- The end result is a sash window draught proofed around it's perimeters, rattles are eliminated and noise resistance is improved.
- If sash cords are a bit frayed, replacing them while draught proofing is a good idea. Add £25+vat per cord.
- All our Work is Guaranteed & Insured. We offer a 12 month guarantee on all labour and parts we supply.
