About our new build mastic in Chawley
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Common call-outs are for sealant that never bonded to the surface and leaking shower tray seals in a new home, on plot handovers, show homes and bathrooms & en suites.
Work in a small place like Chawley just needs the journey and access planning, and the work itself is the same as on any site.
A 12-month guarantee comes as standard.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
- Use the extractor fan every time you shower
- Check bath and shower seals every few months as the house settles
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day before water reaches them.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.

Other services in Chawley
Surface by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. Tell us when the home is open so we can plan around it.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out.
When something else is needed
We’ll always be straight with you, so here’s what new sealant will not do:
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
- Your warranty claim itself, which is between you and the builder
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.

FAQs for Chawley
Do you work for landlords with property near Oxford station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can you do new build mastic in Chawley?
Yes, Chawley is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Why has my new-build shower seal failed already?
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.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
How much does new build mastic cost in Chawley?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
