New build mastic in Somerley
Across Somerley, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. If you have joints pulling apart as timber shrinks and sealant work across a run of new homes, we can put it right, on plot handovers, windows & doors and bathrooms & en suites alike.
For a small place like Somerley, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
A 12-month guarantee comes as standard.

Different surfaces, different methods
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
What new build mastic looks like in Somerley
Somerley 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Fishbourne station, the sealant around baths, showers and frames is worth checking in the first year or two.

Quotes for new build mastic in Somerley
We quote each job individually. These are the things that affect it:
- Whether the work is at height
- The number and length of the joints
- The number of rooms or windows
- The old material and how stubborn it is
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- Any access issues, like height or stairs
- Whether it’s a home or a business
We quote each job on its own, so the first step is telling us about yours. Just ring 0345 464 0079 or email us with the details.
How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Somerley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- 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.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Mention any tricky access

What else we do in Somerley
Do you need new build mastic in Somerley?
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
These are the problems we are asked about most:
- Gaps between new skirting and floors
- Gaps opening as the house dries out and settles
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
Around Somerley, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Whether they’re fully insured
- Is the old sealant removed completely?
- How the surfaces are prepared before sealing
- Whether you can choose the colour
Why act early in Somerley
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. If you’re unsure which you have, phone 0345 464 0079 or drop us an email with photos and we will give you a straight answer. Around Somerley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

FAQs for Somerley
Can you do new build mastic in Somerley?
Yes, Somerley is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
I let a flat near Fishbourne station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Is it worth resealing while the house is still settling?
Any seal that is leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What sealant work can’t fix
Before booking, it’s worth knowing the limits:
- Leaking fittings rather than failed sealant
- Structural cracks in walls or ceilings
- Broken tiles or a split tray
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
