Window & door mastic in Five Oak Green, Kent

Do you need window mastic in Five Oak Green?
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
It’s worth asking for a quote if you see:
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
If you live in an older home near Five Oak Green Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

About our window mastic in Five Oak Green
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on timber windows & doors, patio & French doors and aluminium frames, and the jobs we see most are water coming in at the bottom corners of a door and cracked internal joints between frame and plaster.
Around Five Oak Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as that’s a job for a joiner.
Window mastic in Five Oak Green: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Paddock Wood station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Capel Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a morning for a couple of windows and a door. For a village or hamlet like Five Oak Green, 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.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in

Do you cover Five Oak Green for window mastic?

What does window mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or email us and tell us what needs doing and where.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.

Aftercare tips
Aftercare is simple:
- Keep paint off silicone joints
- Air rooms to keep condensation down around windows
- Clean frames with a soft cloth and soapy water
- Avoid blasting the frames with a pressure washer
Silicone cannot normally be painted, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
Signs to watch for: 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.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
