New-build mastic & snagging in East Preston, West Sussex
Our applicators work in East Preston on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Sealant applied over dusty or wet surfaces
- Gaps behind new kitchen upstands
- Cracked sealant around new window and door frames
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Settlement cracks that need a surveyor
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
What we seal
- Windows & doors
- Kitchens
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
- Show homes
New build mastic in East Preston, done properly
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We are often asked to deal with leaking shower tray seals in a new home and sealant that never bonded to the surface, across bathrooms & en suites, kitchens and windows & doors.
Homes around East Preston range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
Big or small, you get the same 12-month guarantee in East Preston and across West Sussex.

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 an older home around East Preston, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

Common problems we fix in East Preston
Sealant applied onto damp surfaces doesn’t bond well. Site programmes do not always leave time for joints to dry.
Keep an eye out for these signs:
- Sealant that never bonded to the surface
- New-build shower sealant that has already split
- Joints pulling apart as timber shrinks
- Messy sealant that spoils new finishes
Around East Preston, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- Is the old sealant removed completely?
- Whether they’re fully insured
New build mastic in East Preston: local notes
East Preston 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 Angmering station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

How long does new build mastic take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. We will confirm how long when we quote.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Do you work through snagging lists?
Yes. Send the list and a few pictures of the sealant items and we will give you a quote. We’ll flag anything that needs another trade.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes a few hours for most snagging lists, longer for a run of plots. A visit to East Preston is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- 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.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
