Bathroom resealing for homes and businesses in St Nicholas
The bead of silicone around a bath, tray or worktop is what keeps water out of the gaps. Once it cracks or goes mouldy, water starts to find its way through. Our team cut the old bead out completely and lay a new one in anti-fungal sanitary silicone. We work on baths, shower trays & enclosures and sinks & splashbacks, and people most often call us about mouldy sealant that has gone black and a messy, uneven bead from a previous reseal.
In a smaller place like St Nicholas, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What the job involves on each surface
Sinks & splashbacks
The edge of an inset sink is a common place for water to get under the worktop. We reseal the visible edge of the sink where it has failed.
Wet rooms
Wet rooms rely on sound joints at floor and wall junctions. They’re resealed with anti-fungal sanitary silicone, working on the surface joints, not the tanking or drainage.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What bathroom resealing looks like in St Nicholas
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings. St Nicholas is part of Stevenage, one of the post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. Sealant laid over old sealant never bonds properly, so it all has to come out.
For site and facilities teams at buildings such as The Leys Primary and Nursery School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. Letting a property close to Stevenage station? Then mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.
St Nicholas is about 1 mile north of Stevenage, in Hertfordshire. Every kind of property in St Nicholas can book us for bathroom resealing, old or new, large or small. Every job comes with our 12-month guarantee. Our area takes in 381 places across Hertfordshire. We also work in London, around 30 miles away.

St Nicholas questions
Do you cover smaller places like St Nicholas?
Yes. St Nicholas is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Stevenage station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Are you insured?
Yes. We’re fully insured.
How long does a bath or shower reseal take?
A single bath or shower takes about a couple of hours, old sealant removal included. A full bathroom and kitchen can take most of a day.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I choose the colour of the sealant?
There’s a choice: clear, white and colours chosen to suit the room. We’ll talk it through when we quote.
What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes two to three hours for a typical bath, depending on how much old sealant there is for a typical job. Parking around St Nicholas is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- Joints are degreased and any mould is treated.
- 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’re told the cure time, normally around 24 hours.
How to prepare
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
How to get a quote
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.
Related advice
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Use gentle cleaners on the silicone
- Wait for the cure time we give you
- Dry worktop joints after washing up
- Run the extractor fan during and after every shower
Mould needs damp, so keep the room aired. Run the extractor fan during and after a shower, so the silicone gets a chance to dry.
Watch for the early signs: a corner lifting, a gap behind the bead, a dark line under the silicone or a damp patch on the ceiling below. Any of these means the joint needs attention.
Common problems we fix in St Nicholas
Mould is the reason many people want their sealant replaced. Steamy rooms that don’t dry out give mould all the damp it needs, and once it has grown into the bead, cleaning rarely gets it out.
Most people get in touch when they notice one of these:
- Water getting behind the bath panel
- Black mould in the silicone that will not clean off
- Leaking joints on a shower screen
- Smears of silicone across the tiles
If you live in an older home near All Saints Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What happens if it’s left?
Bleach and mould sprays may lighten black marks for a while, but mould that has grown into the sealant tends to return. The lasting answer is to remove the bead and start again. In a smaller place like St Nicholas, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
