New build mastic in Yopps Green
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We work on show homes, bathrooms & en suites and kitchens, and common reasons people get in touch are internal frame sealant that has split and new-build shower sealant that has already split.
Somewhere as small as Yopps Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Joints and finishes in Yopps Green homes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Yopps Green, as everywhere, new build mastic is only as good as the preparation behind it.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Put sealant faults on your snagging list early
- Do not wait for the house to settle if water is getting through
- Follow the cure time we give you
- Avoid running a DIY bead over the old one
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
- Broken tiles or a split tray
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

What happens on the day
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the number of plots for a typical job. Somewhere as small as Yopps Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on
- Mention any parking rules near the property

Advice
How we quote for new build mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- The amount of work
- The product the joint needs
- Whether there’s mould to deal with
- Access and height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Where the job is, and your postcode
- Whether it has been sealed before
- The rough size of the job
- The problem you’ve noticed
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, ring 0345 464 0079 or send us an email.
Why deal with it now?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Yopps Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

When to call us in Yopps Green
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Most people get in touch when they notice something like this:
- Second-fix sealing on new plots
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Sealant that never bonded to the surface
For new homes near Borough Green & Wrotham station, it’s worth checking the sealant early, while snags are still fresh.
