New build mastic in North Hyde, done properly
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. We work on show homes, kitchens and skirting & floors, and common reasons people get in touch are kitchen sealant that has pulled off the wall and new-build shower sealant that has already split.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
All of our work is guaranteed for twelve months.

Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
New build mastic around North Hyde
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. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
For new homes near Southall station, it’s worth checking the sealant early, while snags are still fresh.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Raise failed sealant with the developer while you’re covered
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
- Follow the cure time we give you
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.

Your questions about new build mastic in North Hyde
Is North Hyde in your area for new build mastic?
Yes, North Hyde is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Southall station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
What we cannot put right
A few problems are outside what sealant work can do:
- Broken tiles or a split tray
- Baths and trays that move too much for sealant to cope with
- Disputes or warranty claims with your builder
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.

How the visit works
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 a few hours in a single home, and we explain the cure time before we leave. 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.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive

Do you need new build mastic in North Hyde?
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Look out for these signs:
- Cracked sealant around new window and door frames
- Sealant applied over dusty or wet surfaces
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
North Hyde is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Before booking anyone
- Whether all the old sealant comes out first
- What insurance they hold
- Whether you can choose the colour
- Which sealant they’ll use, and why
Landlord and commercial work in North Hyde
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
What happens if it’s left?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in North Hyde.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.
