New-build mastic & snagging in Brighton, Brighton and Hove
Our applicators work in Brighton on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
- Untidy sealant flagged on a snagging list
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
New build mastic in Brighton, done properly
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. If you’re dealing with worktop and upstand sealant coming away and frame joints opening as the plaster dries, we can put it right, on skirting & floors, kitchens and plot handovers alike.
Commercial units around a large town like Brighton generally have concrete floors with joints that need filling and resealing as they wear. At home, it’s the same idea on a smaller scale: skirtings, thresholds and shower seals.
Your job is guaranteed for a year, as with all our work.

What else we do in Brighton
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours in a single home. For homes and businesses in busier parts of Brighton, parking needs a little planning. Let us know about stairs, lifts or shared entrances too.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Before we arrive
- Clear items away from the joints we are working on
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

Advice
How the job changes by surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Plot handovers
Send us the schedule and any sealant specification. Sealant work across the plot is covered.
Do you need new build mastic in Brighton?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
These are the problems we are asked about most:
- Cracked sealant around new window and door frames
- Messy sealant that spoils new finishes
- Shower seals failing in the first year or two
- Cracked caulk along new skirting
In and around Brighton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote

- How the joint is cleaned and prepared
- Are they insured?

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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Your questions about new build mastic in Brighton
Can you help a landlord with a rental near London Road (Brighton) station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Is new build mastic in Brighton guaranteed?
All our work, in Brighton and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
New build mastic around Brighton
Brighton is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.
If you’ve bought a new home near London Road (Brighton) station, the sealant around baths, showers and frames is worth checking in the first year or two.

Aftercare tips
To keep the joints looking good and working properly:
- Keep pictures and emails about snagging items
- Don’t seal over failed sealant yourself
- Raise failed sealant with the developer while you are covered
- Clean sealant with mild detergent, not abrasives
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.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
What affects the cost of new build mastic
Every job gets its own quote. This is what makes a difference:
- Which sealant suits the joint

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
