About our new build mastic in Shoreditch
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We are often asked to deal with sealant applied over dusty or wet surfaces and kitchen sealant that has pulled off the wall, on bathrooms & en suites, show homes and kitchens.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

New build mastic around Shoreditch
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, Shoreditch can be tricky for parking: let us know about parking bays, permits or a driveway. For new homes near Shoreditch High Street station, it’s worth checking the sealant early, while snags are still fresh.

Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Shoreditch, the repair is bigger than a sealant job.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Damaged fittings that need replacing
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.
Joints and surfaces we work on

What the job involves on each surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.
Plot handovers
Send us the schedule and any sealant specification. Sealant work across the plot is covered to the agreed spec.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

Questions from Shoreditch
Can parking be tricky for a visit in Shoreditch?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you help a landlord with a rental near Shoreditch High Street station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
How do I get a quote for new build mastic in Shoreditch?
We do not publish prices, because the cost 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.
Do you come to Shoreditch?
Yes. We’re based in Crawley and work across South East England, London and Scotland, Shoreditch included.
Are you insured?
Yes. Full insurance covers our work.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
What happens on the day
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
