Sand mastic for homes and businesses in Limehouse
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you have crumbling sand mastic round a window and gaps round a timber door in stone or brick, we can put it right, whatever the surface.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Limehouse as anywhere.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Frames and glazing around Limehouse
With historic houses such as Sutton House (about 2.4 miles north) nearby, there’s older building stock in the area around Limehouse as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Paul's Bow Common, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Limehouse station, any sash windows need sound mastic to keep draughts and rain out.

Why act early in Limehouse
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Limehouse, the repair is bigger than the sealant job would have been.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

When to call us in Limehouse

- Old sand mastic that has cracked, crumbled or fallen out
- Old cement repairs round a window that have failed
- Open joints round the window box
- Failed mastic on an exposed elevation
As a London address, Limehouse can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep modern sealant off the mastic
- Get any rot dealt with first
- Keep sills and gutters clear so water drains away
- Leave the new mastic unpainted
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Your questions about sand mastic in Limehouse
Can you do sand mastic in Limehouse?
Yes, Limehouse is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Can parking be tricky for a visit in Limehouse?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can I choose the sealant colour?
In most cases you can choose. We will explain which colours are available.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours for a single window, longer for several. We’ll give you a better idea when we quote.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. In a London area like Limehouse, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
