Why act early in Tufnell Park

You can phone 0345 464 0079 or email us with a few pictures and we will give you a straight answer. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Tufnell Park, the repair is bigger than a sealant job.

About our new build mastic in Tufnell Park
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on windows & doors, bathrooms & en suites and skirting & floors, and the jobs we see most are sealant work across a run of new homes and shower seals failing in the first year or two.
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.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

How it works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of plots. In Tufnell Park, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Clear items away from the joints we’re working on
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can

What new build mastic looks like in Tufnell Park
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Upper Holloway station, the sealant around baths, showers and frames is worth checking in the first year or two. Tufnell Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Wait for the cure time before using a resealed shower
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the job changes by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.
