Sand mastic in Yeading
Across Yeading, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you have modern sealant on a period surround and open joints round the window box, we can put it right.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Yeading is something to talk through when you book.
All our work is covered by our one-year guarantee, wherever you are in Greater London.

What else we do in Yeading
Why act early in Yeading
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Yeading, the repair is bigger than a sealant job.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Why us?
- Trusted Arbo and Everbuild sealants
- We never seal over old sealant

FAQs for Yeading
Do you work for landlords with property near Southall station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Can you do sand mastic in Yeading?
Yes, Yeading is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
How do I get a quote for sand mastic in Yeading?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
Do you guarantee sand mastic work?
Our one-year guarantee covers every job.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Look over the window mastic once a year
- Renew mastic before redecorating the windows
- Clear gutters so water does not pour onto the windows
- Avoid heavy scraping on the mastic joint
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
How we quote for sand mastic
For a quick quote, just ask. What matters most is:
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- How much there is to do
- The old material and how stubborn it is
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Photos by email, if that’s easy
- If someone has resealed it before
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel

The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a single window, longer for several, including the tidy-up. In Yeading, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on

Common problems we fix in Yeading
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint and we normally remove them.
Keep an eye out for these signs:
- Mastic dropping out of the joint
- Cracked mastic round a front door frame
- Open joints round the window box
- Wind and rain getting in round a sash window
Letting a property close to Southall station? Then any sash windows need sound mastic to keep draughts and rain out.

Sand mastic in Yeading: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. Historic houses like Northolt Manor (about 1.4 miles north-east) are a reminder that the area around Yeading 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.
Schools such as Brookside Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. In the older streets around St Joseph the Worker & Dovetail Centre, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
