How we handle new build mastic in Old Heath
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Typical jobs include sealant that never bonded to the surface and worktop and upstand sealant coming away, on bathrooms & en suites, plot handovers and kitchens.
If you’ve bought a new home in or near Old Heath, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
There’s a 12-month guarantee on every job.

New build mastic in Old Heath: local notes
Old Heath is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Old Heath, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How the job changes by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. Tell us when the home is open so we can plan around it.
Do you need new build mastic in Old Heath?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
It’s worth asking for a quote if you see:
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
- Sealant work across a run of new homes
- Smeared, uneven beads picked up at snagging
For new homes near Hythe station, it’s worth checking the sealant early, while snags are still fresh.

Common questions in Old Heath
Do you work for landlords with property near Hythe station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover Old Heath for new build mastic?
Yes, Old Heath is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Are you insured?
Yes, we’re fully insured for every job we do.
What affects the quote in Old Heath
For a quick quote, just ask. The main things that affect it are:
- The number and length of the joints
- Which sealant suits the joint
- The old material and how stubborn it is
- The number of rooms or windows
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- A few photos by email, if you can
- The rough size of the job
- Where the property is
- If someone has resealed it before
For a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. In a smaller place like Old Heath, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
