About our bathroom resealing in Marshalswick
Across Marshalswick, the joints we reseal are the ones that fail in any home: the long edge of the bath, the base of the shower tray, the back of the basin and the line along the worktop. Each one is stripped, cleaned and dried before new silicone goes in. If you have damp behind the bath or under the tray and gaps between the worktop and the wall, we can help, whatever the surface.
Homes around Marshalswick range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
We stand behind the work with a one-year guarantee.

Why act early in Marshalswick
Most of the work in a good reseal happens before any silicone goes on: removing all the old sealant, degreasing the joint, treating mould and drying it properly. Without that preparation, the new bead won’t last. In a smaller place like Marshalswick, 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.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

When it isn’t the sealant
In fairness, some problems need a different trade:
- A tray that rocks until it’s re-bedded
- Water getting in through the grout rather than the sealant
- A cracked shower tray or bath (that needs repair or replacement)
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What the job involves on each surface
Basins & vanity units
The back of a basin gets wet every time someone washes. Corners behind basins are where mould tends to start, and we treat it exactly as we would a bath.
Wet rooms
Not every wet room leak is a sealant problem. We check the joints and say so if the fault looks to be elsewhere.
Common problems we fix in Marshalswick
Mould is the reason many people want their sealant replaced. Bathrooms without good ventilation keep the silicone damp for hours, and once it has grown into the bead, cleaning rarely gets it out.
Common reasons people contact us are:
- Lumpy, uneven sealant from a DIY attempt
- Cracked, shrunken or lifting silicone
- Mouldy sealant that has gone black
- Shrunken sealant along the back of a worktop
For site and facilities teams at buildings such as St John Fisher Roman Catholic Primary 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.

Landlord and commercial work in Marshalswick
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes half a day or less for one room, longer when the kitchen is included. Parking around Marshalswick is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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’re told the cure time, usually around 24 hours.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Saint Mary's, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Letting a property close to St Albans station? Then a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
