New build mastic in Saltdean
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on show homes, plot handovers and kitchens, and the jobs we see most are leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall.
In smaller places like Saltdean, new homes tend to come as small developments or single plots. 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.

Leave it or put it right?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. Homes in smaller places like Saltdean can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
What you get with us
- White, clear, grey or another colour, product permitting
- A sealant colour to suit the surroundings
- We’re fully insured
- 20+ years of sealant experience

New homes and floors in Saltdean
Saltdean is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, 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.
For new homes near Southease station, it’s worth checking the sealant early, while snags are still fresh.

Common problems we fix in Saltdean
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Signs it’s time to call us include:
- Cracked sealant around new window and door frames
- Shower seals failing in the first year or two
- Gaps behind new kitchen upstands
- Untidy sealant flagged on a snagging list
Around Saltdean, as everywhere, new build mastic is only as good as the preparation behind it.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours in a single home, depending on how much there is to do. In a smaller place like Saltdean, parking is seldom the issue; lanes, gates and long drives are worth mentioning. 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.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in

Saltdean: your questions answered

Can you do new build mastic in Saltdean?
Yes, Saltdean is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear price.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Get in touch with the number of plots and the scope for a clear quote.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
How the job changes by surface
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Show homes
We seal show-home bathrooms, kitchens and frames ready for viewings. We will plan around viewing times.
Looking after it afterwards
Looking after new joints is easy:
- Do not wait for the house to settle if water is getting through
- Clean sealant with mild detergent, not abrasives
- Photograph failed sealant before it’s redone
- Ventilate bathrooms well, especially in the first year
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
