Seaview New Build Mastic
Our applicators work in Seaview on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
- Cracked caulk along new skirting
How the visit works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours in a single home, including the tidy-up. For a village or hamlet like Seaview, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

How we handle new build mastic in Seaview
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. If you are dealing with beads laid onto grit and dust from the build and leaking shower tray seals in a new home, we can put it right, whatever the surface.
Somewhere as small as Seaview, 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.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How we quote for new build mastic
There’s no set price list, because jobs vary so much. What we look at:
- The old material and how stubborn it is
- The type of sealant required
- How many rooms, windows or areas are involved
- The number and length of the joints
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
What we need to know
When you call or email, it’s useful to know:
- Whether it’s a home or a business
- The problem you’ve noticed
- How many joints, rooms or windows are involved

Questions from Seaview
Do you cover Seaview for new build mastic?
Yes, Seaview is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
I let a flat near Smallbrook Junction station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months, large or small.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish and agree it with you.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Seaview.

What else we do in Seaview
What the job involves on each surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Photograph failed sealant before it’s redone
- Get a leaking seal dealt with straight away
- Wait for the cure time before using a resealed shower
- Report sealant problems to your builder during the snagging period
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you, so raise it early.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
What new build mastic looks like in Seaview
Seaview is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. 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.
If you’ve bought a new home near Smallbrook Junction station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Seaview, as everywhere, new build mastic is only as good as the preparation behind it.

What’s near Seaview

Why it’s worth doing now in Seaview
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Seaview, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.
