About our new build mastic in Sarisbury Green
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 sealant actually sticks. Common call-outs are for frame joints opening as the plaster dries and plot mastic for developers ahead of handover, across windows & doors, show homes and kitchens.
For a new home in or near Sarisbury Green, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Each job carries a 12-month guarantee.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
What we can’t put right
In fairness, some problems need a different trade:
- Damaged fittings that need replacing
- A tray or bath that isn’t properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.

Sarisbury Green: your questions answered
Is Sarisbury Green within the area you cover?
Yes, Sarisbury Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Swanwick station?
Yes. We work for landlords and agents as well as householders. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Can I send you my snagging list?
Yes. Send the list and a few pictures of the sealant items and we’ll give you a quote. We’ll tell you if anything on it isn’t a sealant job.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or drop us an email.
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.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
When is the best time to reseal in a new build?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.

Surface by surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
When to call us in Sarisbury Green
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Common reasons people contact us are:
- Beads laid onto grit and dust from the build
- Smeared, uneven beads picked up at snagging
- Kitchen sealant that has pulled off the wall
- Second-fix sealing on new plots
Around Sarisbury Green, as everywhere, new build mastic is only as good as the preparation behind it.
