Why deal with it now?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. In a smaller place like Bewbush, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What you get with us
- Arbo and Everbuild products
- Full insurance on every job
- We agree the colour with you first
- Any old sealant cut out fully, not covered over

New build mastic for homes and businesses in Bewbush
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We’re often asked to deal with kitchen sealant that has pulled off the wall and leaking shower tray seals in a new home, on kitchens, skirting & floors and windows & doors.
In and around Bewbush, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
You get a 12-month guarantee, the same in Bewbush as everywhere else we work.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Joints and finishes in Bewbush homes
Crawley, which Bewbush is part of, is one of England’s post-war new towns. Crawley has kept growing, with newer neighbourhoods added to the original town, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Older homes need their sealant and floor joints renewing, newer ones checking at snagging. 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 Bewbush, as everywhere, new build mastic is only as good as the preparation behind it.

What do you need from me for a quote?
A short description and the location. We’ll ask anything else we need to know.
How long does new build mastic take?
Most jobs take a few hours in a single home, including preparation and clearing up. We will confirm how long when we quote.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
Can I send you my snagging list?

When is the best time to reseal in a new build?
Any seal that’s leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’ll tell you before we start. It won’t solve:
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
- A tray or bath that is not properly supported, until it’s fixed
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

What affects the cost of new build mastic
The quote reflects the job in front of us. We take into account:
- When we can work, for business premises
- The old material and how stubborn it is
- Any mould that needs treating
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- The rough size of the job
- The address or postcode of the job
- Access, such as stairs, a lift or height
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or email us.
What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. It usually takes a few hours in a single home. For a job in Bewbush, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

Advice
Keeping the joints in good condition
After the cure time, these simple habits help:
- Don’t seal over failed sealant yourself
- Look at the sealant regularly in the first couple of years
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Common problems we fix in Bewbush
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Keep an eye out for these signs:
- Worktop and upstand sealant coming away
- Sealant work across a run of new homes
- Joints pulling apart as timber shrinks
- Beads laid onto grit and dust from the build
For new homes near Ifield station, it’s worth checking the sealant early, while snags are still fresh.
