Questions from Five Ash Down
I let a flat near Buxted station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Is Five Ash Down in your area for window mastic?
Yes, Five Ash Down is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing.
Does the work come with a guarantee?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.
Do you work on first-floor windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Window mastic in Five Ash Down
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. We work on patio & French doors, uPVC windows and composite doors, and the jobs we see most are cracked internal joints between frame and plaster and white mastic on grey or black frames.
In a village or hamlet like Five Ash Down, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out 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.

How the visit works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take most of a day for a typical house, less for a few frames. Somewhere like Five Ash Down 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.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
Getting a quote
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.
Advice
What we’re called out for in Five Ash Down
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
People usually contact us when they notice something like this:
- Whistling draughts around closed windows
- Rushed sealant from a window installation
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
If you let a flat or house near Buxted station, renewing tired window mastic between tenants heads off draught and damp complaints.

Why act early in Five Ash Down
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Five Ash Down, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear price before we start.

What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Draughts through the window seals rather than the frame
- A sash or casement that won’t close properly
- Damp problems in the wall away from the window
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal
- Composite doors
- uPVC windows
- Timber windows & doors
- Window sills

Windows and doors in Five Ash Down
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Five Ash Down Independent Chapel, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Buxted CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Make sure the drainage slots aren’t blocked
- Look round the frames every year or so
- Keep timber frames painted
- Avoid harsh chemicals near the mastic
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
How the job changes by surface
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
