How the job changes by surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Window mastic in Mockbeggar, done properly
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. Common call-outs are for mastic that has split away from the wall and old mastic that has gone black or come away, on aluminium frames, window sills and patio & French doors.
Somewhere as small as Mockbeggar, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

What we are called out for in Mockbeggar
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for these signs:
- Cracked internal joints between frame and plaster
- Black, perished sealant on frames
- Rushed sealant from a window installation
- Damp patches on the reveal after heavy rain
Around Mockbeggar, as everywhere, window mastic is only as good as the preparation behind it.

Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:

What else we do in Mockbeggar
For landlords and businesses
We also work for property managers and facilities teams in Mockbeggar and across Hampshire. We can quote a run of properties together, and we’re fully insured.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Looking after it afterwards
After the cure time, these simple habits help:
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Paint up to the joint, not over it
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Frames and glazing around Mockbeggar
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.
If you live in an older home near Church of St Martins, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the quote in Mockbeggar
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- Mould in or behind the old joints
- How much there is to do
- The number of rooms or windows
Some things make a job bigger or smaller: 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.
What we need to know
Before you ask for a quote, have a think about:
- The rough size of the job
- If someone has resealed it before
- Any access issues, like height or stairs
- What’s wrong with the joints now
There’s no standard price list. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or email us.
Questions from Mockbeggar
Do you cover smaller places like Mockbeggar?
Yes. Mockbeggar is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do window mastic in Mockbeggar?
Yes. Our work covers London and the South East, and Mockbeggar is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. You will know the timing when we quote.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels in Mockbeggar.
Do you guarantee window mastic?
Yes, for 12 months. A yearly look at the joints helps them last.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
What we do, step by step
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. For a village or hamlet like Mockbeggar, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
- Tell us if parking is tricky
