Window Mastic in Toy's Hill
Problem with your window and door frames in Toy's Hill? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
Different surfaces, different methods
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
How we handle window mastic in Toy's Hill
From a single sill to a whole house of windows, you will get a clear quote before any work starts. Just call 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached. If you are dealing with rain getting in at the frame or under the sill and cracked internal joints between frame and plaster, we can put it right, on timber windows & doors, aluminium frames and patio & French doors alike.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Toy's Hill as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Toy's Hill homes and the weather
With historic houses such as Chartwell (about 1.1 miles west) nearby, there’s older building stock in the area around Toy's Hill 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. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
For site and facilities teams at buildings such as Ide Hill Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. Toy's Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Toy's Hill is about 4 miles south-west of Sevenoaks, in Greater London.

Toy's Hill: your questions answered
Is Toy's Hill in your area for window mastic?
Yes. Our work covers London and the South East, and Toy's Hill is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Do you work for landlords with property near Edenbridge station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Toy's Hill, along with the rest of our area.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee, and we’re fully insured.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
What we cannot put right
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
- Faulty window hardware
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Aluminium frames
- Window sills
- Patio & French doors
- uPVC windows
- Timber windows & doors
- Composite doors
Leave it or put it right?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Toy's Hill, the repair is bigger than a sealant job.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.
Why choose Mr Mastic in Toy's Hill
- Any old sealant cut out fully, not covered over
- A choice of colours where the product allows
- Tidy, careful work

How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from an hour or two to a full day, depending on how many frames there are in most cases. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Toy's Hill. A visitor permit or a nearby bay makes the visit run more smoothly.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- 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
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height

What we’re called out for in Toy's Hill
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. Backing rod sets the right depth.
Common reasons people contact us are:
- Sealant in the wrong colour for the frame
- Gaps left after new windows were fitted
- Black, perished sealant on frames
- Draughty joints inside around the window
Letting a property close to Edenbridge station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
Before you book anyone
- How long the guarantee is
- Whether they’re fully insured
- How the colour is chosen
- How much experience the applicator has
Looking after it afterwards
After the cure time, these simple habits help:
- Ventilate rooms so frames do not stay wet inside
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
What affects the quote in Toy's Hill
We don’t publish a price list, because jobs vary so much. The quote depends on:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Any working-time requirements on site
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
