DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
How we handle new build mastic in Hackney Wick
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. If you are dealing with kitchen sealant that has pulled off the wall and second-fix sealing on new plots, we can help.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.
You get a 12-month guarantee, the same in Hackney Wick as everywhere else we work.

What else we do in Hackney Wick
What happens if it’s left?
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Why Hackney Wick clients choose us
- Old sealant always removed completely
- A sealant colour to suit the surroundings
- Sanitary silicone with an anti-fungal additive in wet areas
- 180+ five-star Google reviews

These are the problems we’re asked about most:
- Gaps behind new kitchen upstands
- Frame joints opening as the plaster dries
- Gaps between new skirting and floors
- New-build shower sealant that has already split
