About our window mastic in Hildenborough
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on uPVC windows, patio & French doors and composite doors, and the jobs we see most are mastic that’s falling out in pieces and a bead that doesn’t match the frame.
Homes in small places like Hildenborough 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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Hildenborough: your questions answered
Do you cover Hildenborough for window mastic?
Yes. We work across London and the South East, and Hildenborough is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Do you work for landlords with property near Hildenborough station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
Is the new sealant paintable?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we will choose accordingly.
Where are you based?
Mr Mastic is based in Crawley. We cover Hildenborough and the rest of Kent, along with the rest of our area.
Can you match the sealant to my frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.

What happens if it’s left?
Resealing frames is a short job: it takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Where a wall is exposed, as many are in small places like Hildenborough, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What you get with us

How we quote for window mastic
We don’t publish a price list. The quote depends on:
- The old material and how stubborn it is
- How many areas need sealing
- Whether the work is at height
- The number and length of the joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
When you call or email, these details help:
- A few photos by email, if you can
- Whether it’s a home or a business
- Where the job is, and your postcode
- Roughly how big the job is
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
DIY versus a professional finish
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or send us an email.
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.
The process
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes most of a day for a typical house, less for a few frames, depending on the size of the job. Somewhere like Hildenborough 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.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

Hildenborough homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Ightham Mote (about 3 miles north) are a reminder that the area around Hildenborough 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.
For an older house near a landmark such as Parish Church of St John, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Hildenborough station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as Hildenborough Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How the job changes by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
