New build mastic around Otterbourne
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours in a single home. Somewhere like Otterbourne needs a little journey planning: let us know about lanes, gates and parking. 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.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- 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
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on
- Mention any tricky access

Advice
What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- How many rooms, windows or areas are involved
- The size of the job
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
There’s no need for technical detail. Just tell us:
- The problem you’ve noticed
- Any previous sealing or DIY work
- Where the job is, and your postcode
- How we’d reach the joints
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
When something else is needed
A few problems are outside what sealant work can do:
- Plumbing faults behind the sealant
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Questions from Otterbourne
Is Otterbourne in your area for new build mastic?
Yes, Otterbourne 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 tell us what needs doing.
Will you come out to Otterbourne?
Yes. Otterbourne is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you need from me for a quote?
Let us know what needs doing and where, with photos by email if possible. We will ask anything else we need to know.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Is there a guarantee?
Yes. All our work carries our one-year guarantee.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Leave it or put it right?
A hairline gap at a skirting can wait, but water getting through cannot. Not sure whether yours can wait? You can call 0345 464 0079 or send us an email with a few pictures and we’ll give you a straight answer. Around Otterbourne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
