How we handle bathroom resealing in South Mimms
A shower joint gets soaked every day. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. They’re resealed with anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. If you have water getting behind the kitchen upstand and black spots spreading through the bead, we can put it right, on sinks & splashbacks, basins & vanity units and wet rooms alike.
Around South Mimms, it’s houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What happens on the day
The work is kept neat and contained to the joints we are treating. The job usually takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen, and we explain the cure time before we leave. Somewhere like South Mimms needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by protecting the area and stripping out the old bead.
- Next, the joint is cleaned and any mould is treated.
- The joint is left to dry, and baths are filled with water first.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- Finally we tidy up and explain the cure time before we leave.
How to prepare
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

What we can’t put right
New sealant can’t fix everything, and we will tell you before work begins. Sealant won’t put right:
- Water getting in through the grout rather than the sealant
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A cracked shower tray or bath (that needs repair or replacement)
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Common problems we fix in South Mimms
Sealant laid on a damp, dusty or greasy joint never bonds properly. Soap residue, oils and leftover silicone film all get in the way, so a rushed job can start to lift early.
Most people get in touch after spotting one of these:
- Cracked, shrunken or lifting silicone
- Black mould in the silicone that will not clean off
- Gaps where the bath or tray has moved
- Lumpy, uneven sealant from a DIY attempt
If you let a flat or house near Potters Bar station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
Questions to ask before you book
- How the surfaces are prepared before sealing
- What insurance they hold
- Whether the sealant suits the joint
- How long to leave it before use
Bathroom resealing around South Mimms
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as Church of St Giles, walls and floors in older homes can move, and sealant and grout show it first. For site and facilities teams at buildings such as St Giles' CofE Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Keeping the joints in good condition
So the new joints stay in good condition:
- Wipe the sealant dry after showering
- Let new sealant cure fully before it gets wet
- Run the extractor fan during and after every shower
- Keep bottles off the sealant line
Keep water off the new bead until it has cured, following the cure time we give you. After that, a quick wipe after showering helps keep it clean.
A split bead lets water through every time the bath or shower is used. Over time that water reaches floors, walls and ceilings. Resealing early stops it.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

South Mimms: your questions answered
Do you cover smaller places like South Mimms?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Potters Bar station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
How much does bathroom resealing cost in South Mimms?
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. You will get a clear quote before work begins.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Can mouldy silicone be sorted out?
Yes, by replacing the sealant. Cleaning products may lighten it, but the lasting fix is new anti-fungal silicone on a clean, treated joint. Airing the room well helps stop it returning.
Do you do kitchens as well as bathrooms?
Yes. We reseal worktop upstands, sinks and splashbacks, in a kitchen-suitable sealant, matched to the worktop where it’s on show.
Do you guarantee your resealing?
Yes, for 12 months. Looking after the joint as we suggest helps it last.
When can I use the bath or shower again?
Generally after around 24 hours. We will tell you the cure time for the product we used.
Surface by surface
Baths
Baths move more than any other fitting, so we fill it with water before sealing. The joint is then laid with the bath at its lowest point and isn’t torn the first time it’s used.
Kitchen worktops & upstands
Water behind a laminate worktop can make the edge swell. A sound joint along the back edge stops that, as long as the worktop itself is firmly fixed.
