Window mastic in Stansted, done properly
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we’ll say so. We are often asked to deal with cracked or shrunken mastic around the frame and cracked sealant at the sill ends, on uPVC windows, composite doors and aluminium frames.
Homes in small places like Stansted often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, it’s backed by our one-year guarantee.

Common problems we fix in Stansted
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
These are the problems we’re asked about most:
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
Rented homes near Borough Green & Wrotham station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Frames and glazing around Stansted
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Lullingstone Castle (about 4.7 miles west) are a reminder that the area around Stansted has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Wrotham School, larger buildings have plenty of frames, and the mastic around each one ages.
Stansted is about 6 miles north-east of Sevenoaks, in Kent. Stansted gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Stansted is one of 922 places in Kent we cover. Our London page covers work nearby.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
- Keep paint off silicone joints
- Air rooms to keep condensation down around windows
Silicone can’t generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
What happens if it’s left?
Resealing frames is a short job: it takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Around Stansted, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why us?
- Trusted Arbo and Everbuild sealants
- Anti-fungal sanitary silicone in wet areas
- Fully insured
- You choose the colour before work begins

Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the new bead is laid against the frame and the wall and tooled smooth.
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
