How it works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours in a single home from start to finish. For a village or hamlet like Warningcamp, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
- Clear the area around the work

Advice
New build mastic in Warningcamp
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We’re often asked to deal with shower seals failing in the first year or two and gaps behind new kitchen upstands, on show homes, skirting & floors and kitchens.
For a small place like Warningcamp, the journey and access are planned in advance, and the work itself is the same as on any site.
Our work is backed for twelve months, in Warningcamp and everywhere else we cover.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Check bath and shower seals every few months as the house settles
- Photograph failed sealant before it’s redone
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

When it is not the sealant
New sealant can’t fix everything, and we will tell you before we start. Sealant won’t put right:
- Disputes or warranty claims with your builder
- Plumbing faults behind the sealant
- Structural cracks in walls or ceilings
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.

Common problems we fix in Warningcamp
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
These are the problems we’re asked about most:
- Second-fix sealing on new plots
- Cracks appearing as a new home settles
- Sealant applied over dusty or wet surfaces
- Kitchen sealant that has pulled off the wall
For new homes near Arundel station, it’s worth checking the sealant early, while snags are still fresh.
Before booking anyone

- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- Whether they seal over old material or remove it
Why it’s worth doing now in Warningcamp
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Warningcamp can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

Do you cover smaller places like Warningcamp?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Can you do several jobs on one visit?

How much does new build mastic cost in Warningcamp?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
What affects the quote in Warningcamp
Every job gets its own quote. These are the things that affect it:
- Mould in or behind the old joints
- The type of sealant required
- When we can work, for business premises
- The number of rooms or windows
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
