- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
Managing a site like Wingham Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

How we quote for sand mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- The type of sealant required
- The number of rooms or windows
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- If someone has resealed it before
- The type of property
- The address or postcode of the job
- What’s wrong with the joints now
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.
Windows and doors in Broomhill
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Goodnestone Park (about 2.5 miles south) are a reminder that the area around Broomhill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Adisham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Related advice
DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What happens if it’s left?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a small place like Broomhill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Broomhill

Looking after it afterwards
To keep the joints looking good and working properly:
- Sort the mastic before the decorators arrive
- Inspect the joints round the windows every year or so
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
