Window mastic in Borden
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 composite doors, aluminium frames and uPVC windows, and the jobs we see most are hard, cracked sealant around windows and sealant in the wrong colour for the frame.
Outdoor sealant needs dry, clean surfaces, so work on frames around Borden is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Do you need window mastic in Borden?
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. Failed sealant there lets rain into the wall or behind the frame.
Common reasons people contact us are:
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
- Whistling draughts around closed windows
- Black, perished sealant on frames
If you look after a building such as Borden Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What we do, step by step
The work is kept neat and contained to the area we are working on. The job normally takes most of a day for a typical house, less for a few frames. Somewhere like Borden needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises

FAQs for Borden
Do you cover smaller places like Borden?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do window mastic in Borden?
Yes, Borden is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We check where the draught is before any work starts.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
What happens if it’s left?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Around Borden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Borden homes and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Peter and St Paul, the joint between an old wall and a newer frame is normally the first place rain gets in. Letting a property close to Sittingbourne station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Should I try it myself first?
If you do try it yourself, take your time over the 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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
