- Cracks appearing as a new home settles
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
About our new build mastic in Winterbourne
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. Typical jobs include gaps opening as the house dries out and settles and gaps behind new kitchen upstands, on skirting & floors, plot handovers and kitchens.
For a small place like Winterbourne, the journey and access are planned in advance, and the work itself is the same as on any site.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

FAQs for Winterbourne

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Winterbourne?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
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.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Winterbourne.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months, large or small.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Common problems we fix in Winterbourne
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
These are the problems we are asked about most:
- Kitchen sealant that has pulled off the wall
- Messy sealant that spoils new finishes
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
In and around Winterbourne, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How the job changes by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Raise failed sealant with the developer while you are covered
- Photograph failed sealant before it’s redone
- Avoid running a DIY bead over the old one
- Act quickly if a seal starts to leak
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
When it isn’t the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- Damaged fittings that need replacing
- Movement caused by a poorly fitted tray or bath
- Structural cracks in walls or ceilings
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Surfaces we seal

The process
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Winterbourne needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
