How we handle bathroom resealing in Blackwater
With over 20 years in the trade, we reseal baths, showers and kitchens in homes across Blackwater. We are fully insured ARBOMaster approved applicators, and the work comes with a 12-month guarantee. If you’re dealing with water getting behind the bath panel and mouldy sealant that has gone black, we can put it right, whatever the surface.
Somewhere as small as Blackwater, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What happens on the day
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take a morning or an afternoon for most single baths and showers. Somewhere like Blackwater needs a little journey planning: 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 protecting the area and stripping out the old bead, including the film left on the tiles.
- The joint is cleaned, degreased and treated for mould.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- Finally we tidy up and explain the cure time before we leave.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Let us know about parking restrictions

Also in Blackwater
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Blackwater: your questions answered
Will you come out to Blackwater?
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.
Is there a guarantee on bathroom resealing in Blackwater?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can I add another job to the visit?
Yes. Just list everything you need.
Do you have insurance?
Yes. Full insurance covers our work.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long does a bath or shower reseal take?
It takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. You will know how long to expect before we start.
Is it OK to put new sealant on top of the old bead?
No. Fresh silicone can’t stick to the old bead, so it lifts and traps water and mould underneath. All the old sealant comes out first.
What does bathroom resealing cost?
We do not 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.
Bathroom resealing in Blackwater: local notes
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to St. Olave's Church include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Never pick at the silicone with a blade
- Look for lifting corners and small gaps now and then
- Wipe up water along the back of the worktop
- Wipe the sealant dry after showering
Keep water off the new bead until it has cured, which is generally around 24 hours. Once it’s cured, wiping it down after use keeps it looking new.
Each shower pushes a little more water through a failed joint. Over time that water reaches floors, walls and ceilings. Resealing early stops it.
Different surfaces, different methods
Shower trays & enclosures
The vertical joint where a screen profile meets the wall is a common leak point. It’s resealed along with the tray joints, following the enclosure maker’s guidance on which side to seal.
Sinks & splashbacks
Splashbacks in glass, tile or acrylic meet the worktop in a long joint. We renew it in clear, white or a matched colour.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
Mould removers can fade the surface of a stained bead, but mould that has grown into the sealant tends to return. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. Older cottages and farmhouses around Blackwater can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Common problems we fix in Blackwater
Not every tube in the shop is meant for a shower. Acrylic caulk and general-purpose sealants aren’t designed for a joint that is wet every day, so they stain, crack or go mouldy before long. Wet areas call for a sanitary silicone with an anti-fungal additive.
The most common problems we see are:
- Shrunken sealant along the back of a worktop
- Water getting behind the bath panel
- A messy, uneven bead from a previous reseal
- A reseal done over the top of the old bead
Managing a site like Christ The King College? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
