A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How we handle bathroom resealing in Harpenden
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 black spots spreading through the bead and failed sealant on the screen profile, on basins & vanity units, sinks & splashbacks and baths.
Plenty of homes in a town like Harpenden have had new bathrooms and kitchens over the years, some more than once. Sealant run over the top of an old bead is a common cause of leaks and mould, which is why all the old material has to come out first.
All our work is covered by our one-year guarantee, wherever you are in Hertfordshire.

Why act early in Harpenden
A clean new bead makes a room look cared for, which matters if you are letting a property or selling it. A smeared, uneven DIY bead does the opposite. Around Harpenden, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.

Your questions about bathroom resealing in Harpenden
Can you do bathroom resealing in Harpenden?
Yes, Harpenden is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Is bathroom resealing in Harpenden guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
How long will the resealing 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.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
When can I use the bath or shower again?
Around 24 hours is typical, and we confirm the time for the product used. Getting it wet too early can spoil the new joint.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Move toiletries away from the joint
- Avoid abrasive pads on the sealant
- Wipe up water along the back of the worktop
- Wipe the sealant dry after showering
In a kitchen, do not let water sit along the back of the worktop and keep hot pans away from the silicone. The drier the joint stays, the longer it lasts.
Don’t wait for a refit to deal with failed sealant. Like paintwork, sealant needs renewing from time to time, and renewing it as soon as it fails protects everything around it.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes two to three hours for a typical bath, depending on how much old sealant there is in most cases. Parking in a town like Harpenden is usually straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We protect the area and cut out all of the old sealant, including the film left on the tiles.
- Next, the joint is cleaned and any mould is treated.
- The joint is left to dry, and baths are filled with water first.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We clear away and tell you when it can get wet, usually after around 24 hours.
Before we arrive
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Tell us if parking is tricky

Common problems we fix in Harpenden
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. Hot pans and harsh cleaners don’t help.
Keep an eye out for these signs:
- Mouldy sealant that has gone black
- A messy, uneven bead from a previous reseal
- Failed sealant on the screen profile
- Shrunken sealant along the back of a worktop
Homes close to St Nicholas Church include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
