New Build Mastic in Rochester Riverside
Our applicators work in Rochester Riverside on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Leaking shower tray seals in a new home
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
DIY sealant or a professional job?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
About our new build mastic in Rochester Riverside
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We’re often asked to deal with kitchen sealant that has pulled off the wall and cracked caulk along new skirting, on skirting & floors, windows & doors and plot handovers.
Homes around Rochester Riverside range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
There’s a 12-month guarantee on every job.

What we’re called out for in Rochester Riverside
Sealant applied onto damp surfaces doesn’t bond well. Site programmes don’t always leave time for joints to dry before the sealant goes on.
If you can see any of these, it’s time to have the joints looked at:
- Internal frame sealant that has split
- Leaking shower tray seals in a new home
- Plot mastic for developers ahead of handover
- Beads laid onto grit and dust from the build
Around Rochester Riverside, as everywhere, new build mastic is only as good as the preparation behind it.

Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. A visit to Rochester Riverside is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- 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.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Advice
Aftercare tips
To keep the joints looking good and working properly:
- Wipe joints with warm soapy water
- Use the extractor fan every time you shower
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
New build mastic in Rochester Riverside: local notes
Rochester Riverside is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Rochester station, it’s worth checking the sealant early, while snags are still fresh.

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In a smaller place like Rochester Riverside, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
