New build mastic in Kemptown
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first. If you have gaps opening as the house dries out and settles and shower seals failing in the first year or two, we can put it right, whatever the surface.
Where new homes go up in smaller places like Kemptown, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
There’s a 12-month guarantee on every job, whatever its size.

What we are called out for in Kemptown
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
People usually contact us after spotting something like this:
- Untidy sealant flagged on a snagging list
- Sealant work across a run of new homes
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
If you’ve bought a new home near Brighton station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- How hidden problems are handled
- Who turns up on the day
- Are they insured?
- Whether the sealant suits the joint

Common questions in Kemptown
Do you work for landlords with property near Brighton station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Kemptown within the area you cover?
Yes. Kemptown is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
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.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Kemptown.
Different surfaces, different methods
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Plot handovers
Send us the schedule and any sealant specification for a quote. Sealant work across the plot is covered as agreed.
Joints and finishes in Kemptown homes
Kemptown is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Kemptown, as everywhere, new build mastic is only as good as the preparation behind it.

What affects the quote in Kemptown
We don’t publish a price list, because no two jobs are the same. What we look at:
- The size of the job
- Which sealant suits the joint
- Working hours on commercial sites
- Access and height
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Any access issues, like height or stairs
- The address or postcode of the job
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
When it isn’t the sealant
It helps to know what we cannot do too:
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
- Disputes or warranty claims with your builder
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Joints and surfaces we work on
- Bathrooms & en suites
- Skirting & floors
- Show homes
- Plot handovers
- Windows & doors
- Kitchens
Keeping the joints in good condition
After the cure time, these simple habits help:
- Check bath and shower seals every few months as the house settles
- Do not seal over failed sealant yourself
- Open a window or run the fan after bathing
- Clean sealant with mild detergent, not abrasives
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
How it works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. Parking around Kemptown is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
- Let us know about parking restrictions
