- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
- Internal frame sealant that has split
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Get a leaking seal dealt with straight away
- Ventilate bathrooms well, especially in the first year
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
New build mastic for homes and businesses in Trotton
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Typical jobs include kitchen sealant that has pulled off the wall and frame joints opening as the plaster dries, on kitchens, plot handovers and windows & doors.
In a village or hamlet like Trotton, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What else we do in Trotton
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. For a village or hamlet like Trotton, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. In a small place like Trotton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Questions from Trotton
Is Trotton in your area for new build mastic?
Yes. We work across London and the South East, and Trotton is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
Is Trotton within the area you cover?
Yes. Trotton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
What should I tell you?
A short description and the location. We’ll ask anything else we need to know.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
What new build mastic looks like in Trotton
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How the job changes by surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
