Window mastic in Four Elms, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. We are often asked to deal with rushed sealant from a window installation and a bead that doesn’t match the frame, across aluminium frames, composite doors and patio & French doors.
Homes in small places like Four Elms 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.
Each job carries a 12-month guarantee, large or small.

DIY versus a professional finish
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What else we do in Four Elms
Looking after it afterwards
So the new joints stay in good condition:
- Clear any debris from frame drain holes
- Clean frames with a soft cloth and soapy water
- Keep timber frames painted
- Avoid harsh chemicals near the mastic
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Soft or decayed wood in the frame
- Penetrating damp from a failed cavity tray or render
- Condensation trapped between the panes
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Window mastic in Four Elms: local notes
Historic houses like Chartwell (about 2 miles north) are a reminder that the area around Four Elms 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. 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.
Homes close to Congregational Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Four Elms Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Edenbridge station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Why deal with it now?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a small place like Four Elms, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Your questions about window mastic in Four Elms
Can you help a landlord with a rental near Edenbridge station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Can you do window mastic in Four Elms?
Yes. We work across London and the South East, and Four Elms is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames. For a village or hamlet like Four Elms, the journey is planned in advance: 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 start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height
Getting a quote

Advice
Surface 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.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
