New build mastic around Lower Rainham
Lower Rainham is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, 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 Rainham (Kent) station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Lower Rainham, as everywhere, new build mastic is only as good as the preparation behind it.

New build mastic in Lower Rainham
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. Common call-outs are for gaps between new skirting and floors and beads laid onto grit and dust from the build, across bathrooms & en suites, windows & doors and show homes.
For a small place like Lower Rainham, 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 12-month guarantee in Lower Rainham and across Medway.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Act quickly if a seal starts to leak
- Keep water off fresh sealant until it has cured
- Photograph failed sealant before it’s redone
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Lower Rainham, 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.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- 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 are given the cure time.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed to keep callbacks down.
What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. Around Lower Rainham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

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.
Do you work through snagging lists?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.
Do you work for landlords and businesses?

Where are you based?

Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
When something else is needed
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Disputes or warranty claims with your builder
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too in Lower Rainham and across Medway. We can quote a run of properties together, and we are fully insured for the work.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
