About our window mastic in Charing
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. If you have draughty joints inside around the window and black, perished sealant on frames, we can put it right, on uPVC windows, patio & French doors and window sills alike.
In a smaller place like Charing, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How to look after the new joints
So the new joints stay in good condition:
- Keep solvents and bleach off the sealant
- Don’t aim a pressure washer at the joints
- Check the mastic once a year
- Keep paint off silicone joints
Silicone can’t usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Frames and glazing around Charing
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Godinton House (about 3.9 miles south-east) nearby, there’s older building stock in the area around Charing as well as newer homes. 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 Charing station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Church of St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What else we do in Charing
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. Each is cleaned, backed where deep and resealed.
What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Soft or decayed wood in the frame
- Damp coming through the wall itself rather than the frame joint
- Broken hinges, locks or handles
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Common questions in Charing
I let a flat near Charing station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do window mastic in Charing?
Yes, Charing is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We will tell you how long your job needs when we quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months, inside or out.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a few frames, or a day or more for a whole house, including the tidy-up. For a job in Charing, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we look at every frame and agree the list.
- 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.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work

When to call us in Charing
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That is what backing rod is for.
If you can see any of these, it’s time to have the joints looked at:
- Rushed sealant from a window installation
- Cracked or shrunken mastic around the frame
- Water coming in at the bottom corners of a door
- Whistling draughts around closed windows
If you look after a building such as Charing Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- Is the old sealant removed completely?
- Who does the work, and how experienced they are
- What guarantee comes with the work
- How hidden problems are handled
