New build mastic in London Docklands, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you have new-build shower sealant that has already split and sealant applied over dusty or wet surfaces, we can put it right, on bathrooms & en suites, windows & doors and show homes alike.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in London Docklands as anywhere.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Common questions in London Docklands
Is parking an issue for new build mastic in London Docklands?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work for landlords with property near Canary Wharf station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you cover London Docklands?
Yes. We work in London Docklands. To book, phone 0345 464 0079 or send us an email.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we will give you a quote.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Should I wait before resealing?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Surface by surface
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
What we can’t put right
We won’t take on work that will not last, so these are the limits:
- Cracking that points to a structural problem
- Disputes or warranty claims with your builder
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
Surfaces we seal

How to look after the new joints
Aftercare is simple:
- Do not seal over failed sealant yourself
- Keep pictures and emails about snagging items
- Keep water off fresh sealant until it has cured
- Watch for new gaps as the house dries out
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
New homes and floors in London Docklands
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
