Bathroom resealing for homes and businesses in Erith
The bead of silicone around a bath, tray or worktop is what keeps water out of the gaps. When it splits, shrinks or turns black, water gets behind it into walls, panels and floors. Every trace of the old sealant is taken out and replaced with anti-fungal sanitary silicone. Common call-outs are for water getting behind the kitchen upstand and failed sealant on the screen profile, on wet rooms, basins & vanity units and kitchen worktops & upstands.
Hard London water leaves limescale on sealant, grout and taps alike. In Erith, bathroom resealing is as much about a room looking cared for as about keeping water out.
Each job carries a 12-month guarantee, whatever its size.

The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a couple of hours for a single bath or shower. For a job in Erith, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We look at every joint first and check for movement or leaks.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you are told the cure time, generally around 24 hours.
How to prepare
- Clear items away from the joints we are working on
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Advice
Landlord and commercial work in Erith
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Erith homes and their sealant
London’s water is hard, which leaves limescale on sealant, grout and taps. In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early.
In the older streets around Christ Church, older homes can move a little, which is hard on rigid grout and tired sealant. For landlords with property near Erith station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

Leave it or put it right?
Sorting it now is quick: the work takes half a day or less for one room, longer when the kitchen is included. Wait for a leak and you may be looking at panels off, drying out and redecorating too. In a flat in Erith, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Can I do it myself?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Honest limits
A few problems are outside what sealant work can do:
- Movement from a bath with loose feet or no proper support
- Cracked or missing grout between tiles (that is regrouting)
- A tray or bath that is cracked through

Common questions in Erith
Could a tired shower seal in my Erith flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Is parking a problem for a job in Erith?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can mouldy silicone be sorted out?
Yes, we can. We strip the bead, treat the joint and lay new anti-fungal silicone.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.

Do you need bathroom resealing in Erith?
With age, silicone loses its stretch. In kitchens it often shrinks away from the back edge, leaving a thin gap where water and food collect. Heat from the hob and strong sprays speed it along.
Any of these means the joints need attention:
- Lumpy, uneven sealant from a DIY attempt
- Black mould in the silicone that will not clean off
- Splits where the tray meets the wall
- Water escaping at the shower enclosure
For site and facilities teams at buildings such as Christ Church (Erith) CofE Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
