Window & door mastic in Goose Green, Kent
Window mastic in Goose Green from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

- Leaking joints at the ends of sills
- Mastic that has split away from the wall
Window mastic in Goose Green, done properly
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you’re dealing with mastic that has split away from the wall and draughts coming in around windows and doors, we can help, whatever the surface.
In a village or hamlet like Goose Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Faulty window hardware
- Condensation trapped between the panes
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Surfaces we seal
- Aluminium frames
- Timber windows & doors
- Window sills
- Patio & French doors
- uPVC windows
- Composite doors
Aftercare tips
To keep the joints looking good and working properly:
- Avoid blasting the frames with a pressure washer
- Do not use solvent cleaners on the joint
- Keep timber frames painted
- Make sure the drainage slots aren’t blocked
Silicone cannot usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
Goose Green: your questions answered
Will you come out to Goose Green?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Yalding station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
How much does window mastic cost in Goose Green?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we’re fully insured.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Are you insured?
Yes, we’re fully insured for every job we do.
Window mastic in Goose Green: local notes
With historic houses such as Old Soar Manor (about 2.5 miles north-west) nearby, there’s older building stock in the area around Goose Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
If you live in an older home near Church of St Dunstan, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Hadlow Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Goose Green is about 4 miles north-east of Tonbridge, in Kent. Goose Green gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. 922 places in Kent are on our list. Crawley is on our list too, around 25 miles away.
Work in TN11 is quoted and booked the same way as anywhere else. Neighbouring places we cover for window mastic include Hadlow (1 mile south-west), West Peckham (1 mile north), Peckham Bush (1 mile south-east), Swanton (2 miles north) and Golden Green (2 miles south). Further out, we also cover Maidstone (8 miles east), Sevenoaks (8 miles north-west), Royal Tunbridge Wells (8 miles south-west), Gravesend (14 miles north), Tonbridge (4 miles south-west) and Northfleet (14 miles north).
Local landmarks in Goose Green
In Goose Green, that means homes and buildings near The Harrow pub, Hadlow Rural Community School and Hadlow College. Goose Green’s nearest station is Yalding station, about 2.5 miles east. A little further out are Tonbridge Castle (4.4 miles south-west) and Tonbridge Cottage Hospital (5.3 miles south-west).
Common problems we fix in Goose Green
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Most people get in touch when they notice one of these:
- Rain getting in at the frame or under the sill
- A bead that does not match the frame
- Gaps where the sill meets the wall
- Gaps between the frame and the inside reveal
If you let a flat or house near Yalding station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Can I do it myself?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Goose Green, the journey is planned in advance: 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.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

What the job involves on each surface
Composite doors
A composite door usually sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
