Window Mastic in Groombridge
Professional window mastic in and around Groombridge, with every bit of old sealant taken out first.

- Water coming in at the bottom corners of a door
- Old mastic that has gone black or come away
What affects the quote in Groombridge
There’s no set price list, because no two jobs are the same. The quote depends on:
- The type of sealant required
- Any mould that needs treating
- The old material and how stubborn it is
- The number of rooms or windows
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it has been sealed before
- Roughly how big the job is
- Whether it’s a home or a business
- Where the job is, and your postcode
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or email us.
About our window mastic in Groombridge
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, ring 0345 464 0079 or drop us an email with the number of frames and any access details. If you are dealing with cracked internal joints between frame and plaster and cold air getting in at the frame edge, we can put it right, on patio & French doors, composite doors and aluminium frames alike.
Mastic can only go onto a dry, clean joint, so window work in Groombridge is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Housing providers, facilities teams and property managers book us too in Groombridge and across Kent. Several sites can go on one quote, and we’re fully insured for the work.
What happens on the day
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes most of a day for a typical house, less for a few frames for a typical job. Somewhere as small as Groombridge, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
How to prepare
- Clear items away from the joints we’re working on
- Tell us about any water getting in
- Keep pets and children clear of the area while we work

Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.

Windows and doors in Groombridge
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Groombridge Place (about 0.4 miles north-east) are a reminder that the area around Groombridge has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Eridge station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as Groombridge St Thomas' Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Thomas the Apostle, the joint between an old wall and a newer frame is generally the first place rain gets in.
Groombridge is about 4 miles south-west of Royal Tunbridge Wells, in Kent. Across the TN3 area, we can carry out window mastic at your property. 922 places in Kent are on our list, from the larger towns to small villages. We also work in Crawley, about 16 miles from Groombridge.

If you are just outside Groombridge, we cover Birchden (1 mile south-east), Stone Cross (1 mile north), Ashurst (2 miles north-west), Balls Green (2 miles west) and Fordcombe (2 miles north).

What we cannot put right
In fairness, there are a few things sealant won’t fix:
- A door that needs adjusting, rehanging or new seals
- Penetrating damp from a failed cavity tray or render
- Soft or decayed wood in the frame
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
Joints and surfaces we work on
- Aluminium frames
- Patio & French doors
- Window sills
- Composite doors
- uPVC windows
- Timber windows & doors
Surface by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Your questions about window mastic in Groombridge
Do you cover smaller places like Groombridge?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Groombridge in your area for window mastic?
Yes, Groombridge is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
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.
Can new window sealant be painted?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before work begins.
What does window mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or send us an email with a short description of the job.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
Do you seal inside as well as outside?
Yes. Inside, the joint between frame and plaster is sealed neatly.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Leave it or put it right?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Where a wall is exposed, as many are in small places like Groombridge, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
