Richborough Port New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for householders, landlords and businesses in Richborough Port. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Cracks appearing as a new home settles
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
About our new build mastic in Richborough Port
We work in new homes and on new-build sites across Richborough Port. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on windows & doors, kitchens and plot handovers, and common reasons people get in touch are cracked sealant around new window and door frames and kitchen sealant that has pulled off the wall.
Older homes in small places like Richborough Port often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Signs you need new build mastic in Richborough Port
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
The most common problems we see are:
- Joints pulling apart as timber shrinks
- Sealant applied over dusty or wet surfaces
- Leaking shower tray seals in a new home
- Internal frame sealant that has split
For new homes near Thanet Parkway station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- What product goes in the joint
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. In a small place like Richborough Port, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Look at the sealant regularly in the first couple of years
- Put sealant faults on your snagging list early
- Do not seal over failed sealant yourself
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers to help keep mould away.
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.
Different surfaces, different methods
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. 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.
How the visit works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere like Richborough Port needs a little journey planning: 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.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.

New build mastic around Richborough Port
Richborough Port is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
