New build mastic in Ardingly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on skirting & floors, bathrooms & en suites and plot handovers, and common reasons people get in touch are gaps behind new kitchen upstands and sealant work across a run of new homes.
For a small place like Ardingly, the journey and access are planned in advance, and the work itself is the same as on any site.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Should I try it myself first?
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Ardingly questions
Can you do new build mastic in Ardingly?
Yes. Our work covers London and the South East, and Ardingly is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Will you come out to Ardingly?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels in Ardingly.
Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
When is the best time to reseal in a new build?
Any seal that’s leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Joints and finishes in Ardingly homes
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.

Quotes for new build mastic in Ardingly
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- Access and height
- Any working-time requirements on site
- Any mould that needs treating
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How we’d reach the joints
- Roughly how big the job is
- Whether it has been sealed before
- The problem you’ve noticed
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 photos by email if you can.
How to look after the new joints
Looking after new joints is easy:
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
- Record problems with dated photos
- Act quickly if a seal starts to leak
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.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours in a single home. In a small place like Ardingly, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Preparing for the visit
- Keep children and pets away from the work area
- Clear the area around the work
- On commercial sites, let us know about site rules

Advice
Do you need new build mastic in Ardingly?
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.
Keep an eye out for these signs:
- Cracked caulk along new skirting
- Untidy sealant flagged on a snagging list
- Sealant applied over dusty or wet surfaces
- Leaking shower tray seals in a new home
For new homes near Balcombe station, it’s worth checking the sealant early, while snags are still fresh.
