We cover Hollingdean for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.

New build mastic in Hollingdean
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. Common call-outs are for cracks appearing as a new home settles and smeared, uneven beads picked up at snagging, across kitchens, plot handovers and bathrooms & en suites.
Where new homes go up in smaller places like Hollingdean, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote. Homes in smaller places like Hollingdean can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. A visit to Hollingdean is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- 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.
Preparing for the visit
- Tell us about any water getting in
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can

Different surfaces, different methods
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
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.
Signs you need new build mastic in Hollingdean
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Signs it’s time to call us include:
- Internal frame sealant that has split
- Beads laid onto grit and dust from the build
- Kitchen sealant that has pulled off the wall
- Cracked caulk along new skirting
For new homes near Moulsecoomb station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
- Which colour the sealant will be
- Who turns up on the day
What new build mastic looks like in Hollingdean
Hollingdean is within about 2 miles 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Hollingdean, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.

Tell us what needs doing and where, with pictures by email if possible. If we need more, we will ask.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.

How long should I leave it?

New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
- Disputes or warranty claims with your builder
