Window & door mastic in Bishopsbourne, Kent
Window mastic across Bishopsbourne and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Rushed sealant from a window installation
- White mastic on grey or black frames
- Mastic that is falling out in pieces
Aftercare tips
Aftercare is simple:
- Avoid blasting the frames with a pressure washer
- Do not use solvent cleaners on the joint
- Keep drainage slots and sill grooves clear
- Wipe condensation off the frames
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Window mastic for homes and businesses in Bishopsbourne
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before we start. To get one, phone 0345 464 0079 or send us an email with the number of frames and any access details for window mastic in Bishopsbourne. Typical jobs include old mastic that has gone black or come away and cracked sealant at the sill ends, on composite doors, patio & French doors and aluminium frames.
Homes in small places like Bishopsbourne 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How the job changes by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.

Advice
Frames and glazing around Bishopsbourne
Historic houses like Goodnestone Park (about 4.1 miles east) are a reminder that the area around Bishopsbourne 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. 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.
Rented homes near Bekesbourne station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Your questions about window mastic in Bishopsbourne
Can you help a landlord with a rental near Bekesbourne station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Is Bishopsbourne within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is the work guaranteed?
Yes, with our 12-month guarantee. A yearly look at the joints helps them last.
Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you work on first-floor windows?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
Signs you need window mastic in Bishopsbourne
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
These are the problems we are asked about most:
- Damp patches on the reveal after heavy rain
- Cracked internal joints between frame and plaster
- Untidy mastic left by window fitters
- Leaking joints at the ends of sills
For an older house near a landmark such as Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- What happens if they find a problem under the old sealant
- How much experience the applicator has
- Whether you can choose the colour
- How the joint is cleaned and prepared
