Walsworth: your questions answered
Do you work in hotels near Walsworth?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do you work for landlords with property near Hitchin station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Can you get rid of the black mould in my sealant?
Yes, we replace the mouldy bead. Sprays can fade the marks, but cutting it out and resealing is what lasts. Good ventilation helps keep it away.
How much does bathroom resealing cost in Walsworth?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.
Does the resealing come with a guarantee?
Yes, a 12-month guarantee. Good ventilation and gentle cleaning help it last.
When can I use the bath or shower again?
We give you the cure time before we leave, and it’s generally around 24 hours. Using it sooner can damage the bead.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
What bathroom resealing looks like in Walsworth
Walsworth has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. 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 site and facilities teams at buildings such as Highover Junior Mixed and Infant School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to St Faith's Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Letting a property close to Hitchin station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

Why act early in Walsworth
Leaving a split or mouldy bead only stores up trouble. Water that gets behind a bath soaks into the floor, the panel and sometimes the ceiling below, turning a small job into a building repair. In a smaller place like Walsworth, 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.
Doing several joints on one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.

Different surfaces, different methods
Kitchen worktops & upstands
The joint between worktop and wall takes splashes, crumbs and cleaning sprays. We seal them in a colour that suits the worktop.
Shower trays & enclosures
There are normally two jobs in a shower: the tray-to-wall joint and the enclosure joints. Both get soaked every time the shower runs, so both are resealed with anti-fungal sanitary silicone.
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes half a day or less for one room, longer when the kitchen is included, and the area is left clean. A visit to Walsworth is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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, usually around 24 hours.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Move toiletries away from the joint
- Dry the bead with a towel now and then
- Keep the fan on for a while after bathing
- Let new sealant cure fully before it gets wet
Keep bottles and razors off the sealant line, because they trap water against the silicone. Squeegeeing the walls and tray after use helps the joint dry.
A failed kitchen joint is easy to miss. Water gets behind the upstand and into the edge of a laminate worktop, where it can make the board swell. Resealing before that happens protects the worktop.
What we cannot put right
A few problems are outside what sealant work can do:
- A tray that rocks until it’s re-bedded
- Tiles that have come away from the wall
- A tray or bath that is cracked through
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
