Well Head: your questions answered
Do you cover smaller places like Well Head?

Is Well Head in your area for window mastic?
Yes. We work across London and the South East, and Well Head is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Is it worth trying it myself?
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.
What does window mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Do you guarantee window mastic?
Yes. Our one-year guarantee covers every job.
Is the new sealant paintable?
Silicone generally will not take paint. Let us know beforehand, and we will use a paintable product where it suits.
Window mastic in Well Head, done properly
From a single sill to a whole house of windows, you will get a clear quote before we start. To get one, ring 0345 464 0079 or send us an email with the number of frames and any access details. If you have water coming in at the bottom corners of a door and cracked sealant at the sill ends, we can put it right.
Homes in small places like Well Head 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 covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

How the job changes by surface
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant will not do:
- Penetrating damp from a failed cavity tray or render
- A failed sealed unit that has misted up
- Faulty window hardware
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.

Window mastic in Well Head: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Goodnestone Park (about 1.6 miles south) are a reminder that the area around Well Head 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’s traditional sand mastic.
Homes close to St Mary's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Wingham Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Adisham station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
Well Head is about 6 miles east of Canterbury, in Kent. Wherever you are in the CT3 postcode area, we can carry out window mastic at your property. Our Kent coverage runs to 922 places, Well Head among them. Chelmsford is on our list too, around 45 miles away.
We cover every part of CT3 for window mastic and the streets around it. Close by, we work in Wingham (1 mile north-west), Twitham (1 mile east), Wingham Well (1 mile west), Broomhill (1 mile north) and Wingham Green (1 mile west). Further out, we also cover Canterbury (6 miles west), Margate (11 miles north-east), Dover (9 miles south), Folkestone (13 miles south), Ramsgate (10 miles north-east) and Broadstairs (11 miles north-east).
Around Well Head
In Well Head, that means homes and buildings near The Red Lion pub and the streets around them. The nearest railway station is Adisham station, roughly 2 miles south-west of the centre. Well-known places in the area include St Martins Hospital (5 miles west). For a walk, there’s Monk's Wall nature reserve.
How to look after the new joints
Aftercare is simple:
- Clear any debris from frame drain holes
- Keep timber frames painted
- Ventilate rooms so frames don’t stay wet inside
- Don’t use solvent cleaners on the joint
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or drop 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.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
Why deal with it now?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Older cottages and farmhouses around Well Head can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes most of a day for a typical house, less for a few frames. For a village or hamlet like Well Head, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- Frame and wall are cleaned and must be dry before sealing.
- 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
- Let us know about earlier repairs to the joints
- Mention any tricky access
- On commercial sites, let us know about site rules
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
