Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or email us and tell us what needs doing and where.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Dover.
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. We use products from Arbo and Everbuild.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
About our sand mastic in Dover
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead and we will explain which is best for yours. Common call-outs are for old cement repairs round a window that have failed and mastic worn away on windows facing the weather, on timber door frames, tenement windows and period & listed homes.
Around Dover, many houses have gained conservatories, French doors or replacement windows over time. Every addition brings more joints, each wearing at its own pace. Leaks normally start at a sill, a frame head or a glazing joint.
You get a 12-month guarantee, the same in Dover as everywhere else we work.

What else we do in Dover
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Renew mastic before redecorating the windows
- Don’t run silicone over sand mastic
- Clear gutters so water doesn’t pour onto the windows
- Have rotten timber repaired before new mastic goes in
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
Frames and glazing around Dover
Dover is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Parish Church of St Andrew Buckland, the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Dover Priory station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Shatterlocks Infant School, its window and door frames need their mastic kept sound, just like a home’s.

Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Why it’s worth doing now in Dover
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Around Dover, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
