Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Window mastic in Wickford

A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on window sills, composite doors and uPVC windows, and the jobs we see most are rushed sealant from a window installation and hard, cracked sealant around windows.

Around Wickford, many houses have gained conservatories, French doors or replacement windows over time. Every addition brings more joints, each wearing at its own pace. Sills, frame heads and glazing joints are where leaks normally start.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Aftercare tips

To keep the joints looking good and working properly:

Keep timber frames painted
Walk round the house once a year and look at the joints
Use gentle cleaners on frames and sealant
Clear any debris from frame drain holes

Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.

Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.

Frames and glazing around Wickford

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

If you let a flat or house near Wickford station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around St Andrew, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why act early in Wickford

Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.

Signs you need window mastic in Wickford

Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.

It’s worth asking for a quote if you see:

Leaking joints at the ends of sills
Gaps between the frame and the inside reveal
Mastic that has split away from the wall
Cold air getting in at the frame edge

Managing a site like Oakfield Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
