Kingston Gorse Window Mastic
Problem with your window and door frames in Kingston Gorse? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Cracked internal joints between frame and plaster
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
How the job changes by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
Window mastic in Kingston Gorse, done properly
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on aluminium frames, patio & French doors and timber windows & doors, and common reasons people get in touch are old mastic that has gone black or come away and white mastic on grey or black frames.
Homes in small places like Kingston Gorse often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Your job is guaranteed for a year, as with all our work.

Kingston Gorse homes and the weather
Kingston Gorse is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Ferring CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Goring-By-Sea station, renewing tired window mastic between tenants heads off draught and damp complaints.

Common questions in Kingston Gorse
Can you help a landlord with a rental near Goring-By-Sea station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Is window mastic in a coastal place like Kingston Gorse any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Will resealing my frames help with draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Can I paint over the new sealant?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we will choose accordingly.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How long will my window job take?
A handful of frames is a short visit. We confirm the timing with your quote.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What we are called out for in Kingston Gorse
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Most people get in touch when they notice one of these:
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
- Cracked or shrunken mastic around the frame
- A bead that does not match the frame
Homes close to St Andrew's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- What guarantee comes with the work
- How hidden problems are handled
- Which sealant they’ll use, and why
- How long to leave it before use

Advice
Why deal with it now?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Where a wall is exposed, as many are in small places like Kingston Gorse, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

Aftercare tips
So the new joints stay in good condition:
- Paint up to the joint, not over it
- Do not use solvent cleaners on the joint
- Wipe condensation off the frames
- Do not aim a pressure washer at the joints
Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
