Window mastic in Earl's Court
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We’re often asked to deal with gaps where the sill meets the wall and water coming in at the bottom corners of a door, on composite doors, aluminium frames and timber windows & doors.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
Whatever the size of the job, it’s backed by our one-year guarantee.

- Whistling draughts around closed windows
- Mastic that has split away from the wall
- White mastic on grey or black frames

Windows and doors in Earl's Court
Historic houses like Garden Lodge (about 0.3 miles north-west) are a reminder that the area around Earl's Court has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as St Cuthbert with St Matthias CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Cuthbert's, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Different surfaces, different methods
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Why it’s worth doing now in Earl's Court
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Earl's Court, the repair is bigger than a sealant job.

- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
