Window Mastic in Silver Hill
Window mastic for Silver Hill and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Sealant in the wrong colour for the frame
- Mastic that’s falling out in pieces
- Gaps left after new windows were fitted
How we handle window mastic in Silver Hill
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on window sills, aluminium frames and uPVC windows, and common reasons people get in touch are hard, cracked sealant around windows and black, perished sealant on frames.
Mastic can only go onto a dry, clean joint, so window work in Silver Hill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
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.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep solvents and bleach off the sealant
- Don’t paint over the silicone
- Air rooms to keep condensation down around windows
- Clear any debris from frame drain holes
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
Frames and glazing around Silver Hill
Historic houses like Bateman's (about 4.4 miles west) are a reminder that the area around Silver Hill has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Etchingham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a handful of frames, longer for a whole house for a typical job. Somewhere like Silver Hill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
- Mention if the joints have been sealed before

Related advice
Why deal with it now?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like Silver Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why us?
- Colour picked to suit the job
- Colour agreed with you before work begins
- A 12-month guarantee on all work
- Sanitary silicone with an anti-fungal additive in wet areas

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Questions from Silver Hill
Do you cover smaller places like Silver Hill?
Yes. Silver Hill 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.
Can you do window mastic in Silver Hill?
Yes. Our work covers London and the South East, and Silver Hill is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Silver Hill and the rest of East Sussex.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
Do you need window mastic in Silver Hill?
Water runs down the glass onto the sill, 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.
Most people get in touch after spotting something like this:
- Rain getting in at the frame or under the sill
- Black, perished sealant on frames
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
If you look after a building such as Hurst Green Church of England Primary School and Nursery, larger buildings have plenty of frames, and the mastic around each one ages.
