How bathroom resealing works in WD17
A reseal only lasts if the joint is properly prepared. The old sealant is removed to the last smear, after which the joint is degreased and any mould treated. Only once it’s dry does the new bead go on. We work on shower trays & enclosures, kitchen worktops & upstands and wet rooms, and people most often call us about leaking joints on a shower screen and two layers of silicone, both failing.
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take around two hours for one bath or shower, longer for a whole bathroom.
- We protect the area and cut out all of the old sealant.
- We clean and degrease the joint and treat any mould.
- We let it dry fully and fill the bath with water before sealing.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- Finally we tidy up and explain the cure time before we leave.
What you’ll pay
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

Bathroom resealing across WD17: local notes
Across WD17, from Watford, Cassiobury and Oxhey outwards, we see bathrooms and kitchens of every age. Sealant and grout wear out in all of them, whether it’s a family bathroom, a rented flat or a hotel en suite.
Hard water across most of the South East leaves limescale on sealant, grout and fittings. For any job in WD17, joints are cleaned back properly before anything new goes in.
Cassiobury: Homes close to St John's Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Managing a site like Watford St John's Church of England Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep scourers and sharp tools away from the bead
- Don’t let bottles sit on the bead
- Wait for the cure time we give you
- Clean with a mild bathroom cleaner and a soft cloth
Don’t stand bottles along the bead, because they trap water against the silicone. A quick squeegee after showering keeps water from sitting on the joint.
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.
Different surfaces, different methods
Wet rooms
Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Cracked grout in a corner can be cut out and replaced with silicone.
Kitchen worktops & upstands
Worktop joints get wet and wiped every day. The new bead is colour-matched where it shows, so the line does not stand out.
What we’re called out for in WD17
With age, silicone loses its stretch. Along worktops it tends to pull back from the wall, leaving a thin gap where water and food collect. Heat from the hob and strong sprays speed it along.
Common reasons people contact us include:
- Lumpy, uneven sealant from a DIY attempt
- A bead that has pulled away from the tiles
- Black mould in the silicone that will not clean off
- A reseal done over the top of the old bead
How we quote for bathroom resealing
The quote reflects the job in front of us. We take into account:
- Access and height
- Any working-time requirements on site
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
When you contact us, these details help:
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- Roughly how big the job is
- The address or postcode of the job
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or drop us an email.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
WD17 questions
How long does the new silicone need before I use the shower?
Around 24 hours is typical, and we confirm the time for the product used. Getting it wet too early can spoil the new joint.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Are you fully insured?
Yes. We are fully insured for domestic and commercial work.
Can you just seal over the old silicone?
No. It’s a common reason for reseals failing. The old joint is stripped, cleaned and resealed from scratch.
