What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It generally takes a few hours in a single home. In a smaller place like Fishbourne, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- Keep children and pets away from the work area

About our new build mastic in Fishbourne
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. If you have internal frame sealant that has split and sealant applied over dusty or wet surfaces, we can help.
For a new home in or near Fishbourne, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
- Deciding who is responsible under a builder’s warranty
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.

How we quote for new build mastic
The quote reflects the job in front of us. We take into account:
- Mould in or behind the old joints
- The old material and how stubborn it is
- Which sealant suits the joint
- The number and length of the joints
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Whether it has been sealed before
- What’s wrong with the joints now
Every job is quoted individually. Simply phone 0345 464 0079 or email us and describe the job, and pictures are welcome.
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. Homes in smaller places like Fishbourne can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Why us?
- Domestic, commercial and hotel work
- Old sealant always removed completely
- Sealant colour chosen to suit
- We leave the area clean and tidy

Questions from Fishbourne
Do you cover smaller places like Fishbourne?
Yes, Fishbourne is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do new build mastic in Fishbourne?
Yes. We work across London and the South East, and Fishbourne is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What does new build mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.

What else we do in Fishbourne
Different surfaces, different methods
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What new build mastic looks like in Fishbourne
Fishbourne is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.
If you’ve bought a new home near Fishbourne station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Fishbourne, as everywhere, new build mastic is only as good as the preparation behind it.
