New build mastic in Newchurch
We work in new homes and on new-build sites across Newchurch. 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 show homes, bathrooms & en suites and skirting & floors, and the jobs we see most are plot mastic for developers ahead of handover and shower seals failing in the first year or two.
Work in a small place like Newchurch just needs the journey and access planning, and once on site, the job is the same as anywhere.
All our work comes with our 12-month guarantee.

Joints and finishes in Newchurch homes
Newchurch is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Newchurch, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Sandown station, the sealant around baths, showers and frames is worth checking in the first year or two.

How the job changes by surface
Show homes

Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first.

At the end, we look at the finished work together and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job.

- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- 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.

Related advice
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Avoid running a DIY bead over the old one
- Get a leaking seal dealt with straight away
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
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.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- How much there is to do
- Whether there’s mould to deal with
What you pay reflects the work, not guesswork. That is why we ask about the job first.

There’s no need for technical detail. It helps if you can tell us:
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, phone 0345 464 0079 or send us an email.
