Signs you need new build mastic in Ravenstone
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
The most common problems we see are:
- Sealant applied over dusty or wet surfaces
- Sealant work across a run of new homes
- Gaps between new skirting and floors
- Leaking shower tray seals in a new home
In and around Ravenstone, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic in Ravenstone, done properly
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on plot handovers, kitchens and skirting & floors, and people most often call us about shower seals failing in the first year or two and second-fix sealing on new plots.
Older homes in small places like Ravenstone often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Advice
Your questions about new build mastic in Ravenstone
Can you do new build mastic in Ravenstone?
Yes, Ravenstone is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Is new build mastic in Ravenstone guaranteed?
All our work, in Ravenstone and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
My new home is still under warranty. Should I contact you?
If you are still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
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. We can always put it right if it fails.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with photos if you can, and we’ll quote. We’ll tell you if anything on it is not a sealant job.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. In a small place like Ravenstone, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

Different surfaces, different methods
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
New build mastic around Ravenstone
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.
For jobs in and around Ravenstone, choosing the right material for each joint is as important as a tidy finish.

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.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
When something else is needed
In fairness, some problems need a different trade:
- Baths and trays that move too much for sealant to cope with
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
