Window Mastic in Graveney
Professional window mastic in and around Graveney, with old sealant always removed completely and a 12-month guarantee.
- Rushed sealant from a window installation
- White mastic on grey or black frames
- Cold air getting in at the frame edge
How to look after the new joints
To keep the joints looking good and working properly:
- Do not aim a pressure washer at the joints
- Ventilate rooms so frames do not stay wet inside
- Keep solvents and bleach off the sealant
- Don’t paint over the silicone
Silicone cannot generally be painted, so if you’re 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 it pays to reseal before that happens.
Window mastic for homes and businesses in Graveney
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on aluminium frames, window sills and patio & French doors, and the jobs we see most are leaking joints at the ends of sills and gaps left after new windows were fitted.
Around Graveney, 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.
There’s a 12-month guarantee on every job, large or small.

What affects the cost of window mastic
There’s no set price list, because no two jobs are the same. What we look at:
- The product the joint needs
- When we can work, for business premises
- Any mould that needs treating
- Access and height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Roughly how big the job is
- Access, such as stairs, a lift or height
- The address or postcode of the job
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Graveney: your questions answered
Do you cover smaller places like Graveney?
Yes. Graveney is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Faversham station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Can new window sealant be painted?
Most silicone can’t be painted. Let us know beforehand, and we’ll use a paintable product where it suits.
Are you fully insured?
Yes. We’re fully insured.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.

Surface by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as a joiner will need to deal with it.
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.

How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. In a small place like Graveney, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

When to call us in Graveney
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
It’s worth asking for a quote if you see:
- Rain getting in at the frame or under the sill
- Cold air getting in at the frame edge
- Hard, cracked sealant around windows
- Cracked sealant at the sill ends
In the older streets around Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before you book
- Whether they seal over old material or remove it
- What the cure time is
- The length of the guarantee
- Whether they’re fully insured
Graveney homes and the weather
Graveney is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Faversham station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like Graveney Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
