Bathroom resealing across AL4: what to expect
We fill the bath before sealing it. The weight settles the bath to its lowest point, so the bead is not stretched the first time someone gets in. Quick jobs often leave it out, and it makes a real difference. Typical jobs include leaks into the floor or ceiling below and a reseal done over the top of the old bead, on wet rooms, sinks & splashbacks and baths.
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work normally takes two to three hours for a typical bath, depending on how much old sealant there is.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
What you’ll pay
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.

Where we work in AL4
Across AL4, from St Albans, Bernards Heath and Marshalswick 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.
London and the South East have homes from every era, from period terraces to post-war new towns and new estates. The right sealant depends on the age and materials of the building.
Marshalswick: If you look after a building such as St John Fisher Roman Catholic Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For landlords with property near St Albans station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
When it isn’t the sealant
Before you book, it’s worth knowing the limits too:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A cracked shower tray or bath (that needs repair or replacement)
- Cracked or missing grout between tiles (that’s regrouting)
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How we quote for bathroom resealing
For a quick quote, just ask. The main things that affect it are:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The size of the job
- When we can work, for business premises
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What to tell us for a quote
When you contact us, these details help:
- The address or postcode of the job
- Access, such as stairs, a lift or height
- The type of property
- If someone has resealed it before
Every job is quoted individually. Simply ring 0345 464 0079 or send us an email and describe the job and send photos if you have them.
Different surfaces, different methods
Basins & vanity units
Basin joints are short and close to eye level: the bead is right in front of you, so it’s tooled cleanly and evenly, in white, clear or a colour to suit.
Wet rooms
Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.
Common problems we fix in AL4
Silicone does not last for ever. Every shower, every splash and every wipe with a cleaner take their toll over the years, and how long it lasts comes down to use, cleaning and ventilation.
These are the problems we are asked about most:
- Failed sealant on the screen profile
- Two layers of silicone, both failing
- Splits where the tray meets the wall
- Gaps between the worktop and the wall
AL4: your questions answered
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.
How do I get a quote for bathroom resealing in AL4?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you guarantee your resealing?
Yes, for 12 months. Looking after the joint as we suggest helps it last.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
Is white the only colour available?
We can use white, clear or a colour to suit. On a worktop we colour-match where the joint shows.
