Advice
How we handle sand mastic in Tadmarton
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We work on tenement windows, timber door frames and sash and case windows, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and gaps round a timber door in stone or brick.
Around Tadmarton, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, 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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Your questions about sand mastic in Tadmarton
Is Tadmarton in your area for sand mastic?
Yes, Tadmarton is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Is Tadmarton within the area you cover?
Yes. Tadmarton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
Are you insured?
Yes, we’re fully insured.
What happens if it’s left?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Around Tadmarton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Common problems we fix in Tadmarton
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Any of these means the joints need attention:
- Open joints round the window box
- Draughts and rain around sash boxes
- Old cement repairs round a window that have failed
- Silicone on a period window that looks wrong
If you live in an older home near Church of St Nicholas, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before you book
- How long the guarantee is
- How hidden problems are handled
- Which colour the sealant will be
- How the surfaces are prepared before sealing
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Plan mastic work ahead of painting
- Check with your local planning authority if your home is listed
- Have rotten timber repaired before new mastic goes in
- Keep modern sealant off the mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Frames and glazing around Tadmarton
With historic houses such as Broughton Castle (about 1.5 miles east) nearby, there’s older building stock in the area around Tadmarton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Banbury station, any sash windows need sound mastic to keep draughts and rain out.
