Draught proofing and overhaul

Approximately 30% of our annual work consists of draught-proofing & overhauling existing period windows. This service offers great value for money with superb results.

We begin by dismantling the existing windows and removing the upper and lower sashes and weights. We dispose of old cords, fittings, parting and staff beads.

We then remove excess build-up of paint on the contact running surfaces of the box frame and sashes to ensure smooth movement once re-assembled.
At this stage we check for and repair any areas of small rot damage that may have been missed at the survey stage and service the pulley wheels, replacing any that are defective.

Sashes are weighed to ensure correct balance and weights are adjusted as necessary. Any loose putty is replaced and weak sash joints are glued, screwed and epoxy resin filled. High strength nylon sash cords are installed along with the weights and the top sash is planed in, fitted and checked for smooth operation to ensure many more years of service.

New parting beads incorporating brush pile weather stripping are installed to the sides and top of the box frame. This draught proofs the gap between the frame and top sash effectively.

We then draught-proof the lower sash meeting rail, again using a brush pile weather seal to ensure an effective seal. The lower sash is planed or packed as required to ensure the meeting rails sit level before attaching to the cords.

Once the lower sash has been checked for smooth operation, new staff beads are measured and mitre cut to fit the four sides of the internal box. We machine these with brush pile weather seal before fixing them into place to make sure that the between upper and lower sash is entirely draught proof.

We then install a full set of window fittings in your choice of finish including brass, satin chrome or polished chrome including sash lifts, external pull down handles, and centre catch and two key-operated security restrictor bolts.

Finally any bare timber is undercoated, dust sheets are removed and the room is vacuumed - leaving you with a rattle free, overhauled, draught proofed and secure window.

*Please note this is a carpentry based service and the window may still require preparation and painting after we have completed our works, the general condition of the paintwork remains the same*
