Sand mastic in Shoreditch
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. We are often asked to deal with silicone on a period window that looks wrong and window mastic to renew ahead of painting, on sash and case windows, stone surrounds and timber door frames.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What sand mastic looks like in Shoreditch
With historic houses such as Mansion House (about 1 mile south-west) nearby, there’s older building stock in the area around Shoreditch 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Shoreditch is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For an older house near a landmark such as St Leonard's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

What we are called out for in Shoreditch
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they generally need raking out.
Most people get in touch after spotting something like this:
- Gaps where the frame meets the masonry
- Mastic worn away on windows facing the weather
- Gaps round a timber door in stone or brick
- Patchy fillers round a sash window
For landlords with property near Shoreditch High Street station, any sash windows need sound mastic to keep draughts and rain out.

Shoreditch: your questions answered
Do you cover Shoreditch for sand mastic?
Yes, Shoreditch is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop 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 Shoreditch?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Are you insured?
Yes. Full insurance covers our work.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Why deal with it now?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. In a flat in Shoreditch, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

The process
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. The work usually takes a few hours for a single window, longer for several. In Shoreditch, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
