About our sand mastic in West Silvertown
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. We work on period & listed homes, sash and case windows and tenement windows, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and tired mastic found when preparing windows for paint.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in West Silvertown.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Common questions in West Silvertown
Can you do sand mastic in West Silvertown?
Yes. Our work covers London and the South East, and West Silvertown is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Is parking a problem for a job in West Silvertown?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Is sand mastic better than silicone for my windows?
It depends on the window. Period windows in stone or brick normally suit sand mastic and newer frames normally get a flexible sealant.
What does sand mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
Are you ARBOMaster approved?

Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Are you fully insured?
Yes. Mr Mastic is fully insured.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
What affects the cost of sand mastic
There’s no set price list. What we look at:
- Which sealant suits the joint
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- The problem you’ve noticed
- Any previous sealing or DIY work
- A few pictures by email, if you can
- Whether it’s a home or a business

Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

What else we do in West Silvertown
West Silvertown homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
Managing a site like Britannia Village Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. As a London address, West Silvertown can be tricky for parking: let us know about parking bays, permits or a driveway.

Surface by surface
Timber door frames
Round a period front door, sand mastic gives the right look.
Stone surrounds
Old stone surrounds are often uneven, so the gap isn’t the same all the way round. We shape it by hand to follow the stone.
What happens if it’s left?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. In a flat in West Silvertown, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- Neat joints and a tidy finish
- 4.9 on Google from 180+ five-star reviews
- Approved under the ARBOMaster scheme
- Anti-fungal sanitary silicone in wet areas

Signs you need sand mastic in West Silvertown
Rain on the window surround works into any crack and loosens it further. Exposed elevations usually fail first.
Look out for any of the following:
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
- Mastic dropping out of the joint
- Patchy fillers round a sash window
If you let a flat or house near Custom House station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
