About our new build mastic in Bilsham
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you are dealing with cracked sealant around new window and door frames and gaps opening as the house dries out and settles, we can help, on show homes, kitchens and skirting & floors alike.
Around Bilsham, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work is covered by a one-year guarantee, wherever you are in West Sussex.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Follow the cure time we give you
- Do not seal over failed sealant yourself
- Use the extractor fan every time you shower
- Look at the sealant regularly in the first couple of years
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
When it isn’t the sealant
New sealant cannot fix everything, and we will tell you before any work starts. Sealant will not put right:
- Your warranty claim itself, which is between you and the builder
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. Somewhere like Bilsham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit

Advice
Common questions in Bilsham
Is Bilsham within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Barnham station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long before the joint can be used?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Do you work through snagging lists?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What we’re called out for in Bilsham
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.
The problems people generally mention when they call are:
- Leaking shower tray seals in a new home
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
Around Bilsham, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Who does the work, and how experienced they are
- Is VAT in the price?
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant
Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
New homes and floors in Bilsham
Bilsham is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Barnham station, it’s worth checking the sealant early, while snags are still fresh.
