How it works
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours in a single home, depending on the amount of work. For a village or hamlet like Nettlestone, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks

New build mastic in Nettlestone
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We work on bathrooms & en suites, kitchens and windows & doors, and the jobs we see most are internal frame sealant that has split and messy sealant that spoils new finishes.
Around Nettlestone, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

Different surfaces, different methods
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Show homes
We seal show-home bathrooms, kitchens and frames ready for viewings. We’ll plan around viewing times.
New homes and floors in Nettlestone
Nettlestone is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Nettlestone, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we’re called out for in Nettlestone
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
These are the problems we are asked about most:
- Second-fix sealing on new plots
- Frame joints opening as the plaster dries
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
For new homes near Smallbrook Junction station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Are they insured?
- Is VAT in the price?
- Who does the work, and how experienced they are
- How long to leave it before use
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Keep water off fresh sealant until it has cured
- Don’t seal over failed sealant yourself
- Ventilate bathrooms well, especially in the first year
- Do not wait for the house to settle if water is getting through
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

When you contact us, these details help:
- What the problem is, such as mould, gaps, leaks or cracking

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Questions from Nettlestone
Is Nettlestone within the area you cover?
Yes, smaller places are covered as well as towns. 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 do new build mastic in Nettlestone?
Yes, Nettlestone is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Who should fix failed sealant in a new build?
If you are still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Leaking fittings rather than failed sealant
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
