New build mastic in Wrotham: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

New build mastic in Wrotham
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on kitchens, bathrooms & en suites and plot handovers, and the jobs we see most are kitchen sealant that has pulled off the wall and plot mastic for developers ahead of handover.
For a small place like Wrotham, the journey and access are planned in advance, and the work itself is the same as on any site.
Whatever the size of the job, you get the same one-year guarantee.

Questions from Wrotham
I let a flat near Borough Green & Wrotham station. Can you help?
Yes. We work for letting agents and landlords 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.
Will you come out to Wrotham?
Yes. Wrotham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before we start.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Signs you need new build mastic in Wrotham
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
If you can see any of these, it’s time to have the joints looked at:
- Internal frame sealant that has split
- Kitchen sealant that has pulled off the wall
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
In and around Wrotham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Before you book anyone
- Whether they seal over old material or remove it
- What insurance they hold
- How the colour is chosen
- How the joint is cleaned and prepared
Why it’s worth doing now in Wrotham
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you are unsure which you have, call 0345 464 0079 or drop us an email with photos. Around Wrotham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and send you a clear quote before any work starts.
What you get with us
- Approved under the ARBOMaster scheme
- White, clear, grey or coloured to suit, where the product allows
- Any old sealant cut out fully, not covered over

How the job changes by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Looking after it afterwards
To keep the joints looking good and working properly:
- Don’t seal over failed sealant yourself
- Open a window or run the fan after bathing
- Follow the cure time we give you
- Watch for new gaps as the house dries out
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
The process
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours in a single home, and we tell you how long to leave it before we go. Somewhere as small as Wrotham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work

- Any working-time requirements on site
- The type of sealant required
- How much old sealant there is and how hard it is to remove
