About our new build mastic in Ostend
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. Common call-outs are for gaps opening as the house dries out and settles and sealant work across a run of new homes, on bathrooms & en suites, show homes and kitchens.
Work in a small place like Ostend just needs the journey and access planning, and the work itself is the same as on any site.
Our work is backed for twelve months, in Ostend and everywhere else we cover.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Questions from Ostend
Can you help a landlord with a rental near Burnham-On-Crouch station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is Ostend within the area you cover?
Yes. Ostend 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.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.
What does new build mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Joints and finishes in Ostend homes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Follow the cure time we give you
- Use the extractor fan every time you shower
- Raise failed sealant with the developer while you are covered
- Check bath and shower seals every few months as the house settles
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.
