About our window mastic in Payden Street
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we will say so. If you are dealing with cracked sealant at the sill ends and damp patches on the reveal after heavy rain, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Payden Street is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes most of a day for a typical house, less for a few frames from start to finish. Somewhere like Payden Street needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Clear the area around the work
- Tell us if parking is tricky
- Tell us about any water getting in

What else we do in Payden Street
Windows and doors in Payden Street
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. Historic houses like Belmont House and Gardens (about 4.3 miles east) are a reminder that the area around Payden Street has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near Church of St Margaret, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Lenham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Wipe condensation off the frames
- Walk round the house once a year and look at the joints
- Keep solvents and bleach off the sealant
- Wash the frames with mild soapy water
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
What the job involves on each surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
What affects the quote in Payden Street
Your quote is based on your job. We look at:

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, 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.
When to call us in Payden Street
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Signs it’s time to call us include:
- Rain getting in at the frame or under the sill
- Mastic that has split away from the wall
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
For site and facilities teams at buildings such as The Lenham School, larger buildings have plenty of frames, and the mastic around each one ages.

Payden Street: your questions answered
Is Payden Street within the area you cover?
Yes. Payden Street is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Lenham station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Are you fully insured?
Yes. We are fully insured.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How long will my window job take?
A few frames take a few hours. You’ll get a timescale with the quote.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
What we can’t put right
Before booking, it’s worth knowing the limits too:
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
- A frame that has rotted at the joint
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
