Window mastic in Frant, done properly
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. We work on uPVC windows, aluminium frames and patio & French doors, and common reasons people get in touch are mastic that has split away from the wall and leaking joints at the ends of sills.
Mastic can only go onto a dry, clean joint, so window work in Frant is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months.

Your questions about window mastic in Frant
Is Frant in your area for window mastic?
Yes. We work across London and the South East, and Frant is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Do you work for landlords with property near Frant station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where do you work from?
Mr Mastic is based in Crawley. We cover Frant and the rest of Kent, along with the rest of our area.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
How the job changes by surface
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall and tooled smooth.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
We also work for property managers and facilities teams in Frant and across Kent. Several sites can go on one quote.
What we can’t put right
It helps to know what we can’t do:
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
- Faulty window hardware
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.

The process
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. Somewhere like Frant 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.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
Why deal with it now?
Resealing frames is a short job: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Frant, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

Signs you need window mastic in Frant
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.
If you can see any of these, it’s time to have the joints looked at:
- Gaps left after new windows were fitted
- Black, perished sealant on frames
- Draughts coming in around windows and doors
- Draughty joints inside around the window
Schools such as Frant Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Window mastic in Frant: local notes
Historic houses like Wadhurst Castle (about 3.5 miles south-east) are a reminder that the area around Frant has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
Rented homes near Frant station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as The Parish Church of St Alban, the joint between an old wall and a newer frame is generally the first place rain gets in.
