Bathroom resealing across Portsmouth: what to expect
We fill the bath before sealing it. A full bath sits slightly lower than an empty one, so the new joint isn’t pulled apart the first time it’s used. It’s a small step that rushed reseals tend to skip. We work on baths, sinks & splashbacks and shower trays & enclosures, and common reasons people get in touch are failed sealant on the screen profile and new sealant laid over old sealant that is now lifting.
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes around two hours for one bath or shower, longer for a whole bathroom.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- We clean and degrease the joint and treat any mould.
- The joint is left to dry, and baths are filled with water first.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We tidy up and give you the cure time, generally around 24 hours.

Bathrooms and kitchens across Portsmouth
Across Portsmouth, from Southsea, Milton and Landport 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.
From Victorian terraces to post-war new towns and modern estates, homes across the South East and London cover every era. The right sealant depends on the age and materials of the building, wherever it is in Portsmouth. In the coastal parts of Portsmouth, the sea-facing side of a building takes the most weather, so they’re often the first to fail. The right product and careful preparation help it last.
Portsmouth: Homes close to St Wilfrid include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Fratton station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
Leave it or put it right?
Fresh sealant smartens a bathroom or kitchen with very little disruption, which matters if you’re letting a property or selling it. Lumpy sealant with smears on the tiles has the opposite effect.

Work for landlords, hotels and businesses
We also work for property managers and facilities teams across Portsmouth. Several sites can go on one quote, and we’re fully insured for the work.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What affects the quote in Portsmouth
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- The old material and how stubborn it is
- When we can work, for business premises
- Access and height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
To help us quote quickly, please include:
- The rough size of the job
- The problem you’ve noticed
- Whether it’s a home or a business
- If someone has resealed it before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or email us.
Why it fails
Mould is the reason many people want their sealant replaced. Steamy rooms that don’t dry out give mould all the damp it needs, and once it has grown into the bead, cleaning rarely gets it out.
Most people get in touch when they notice one of these:
- Splits where the tray meets the wall
- Water getting behind the bath panel
- Water escaping at the shower enclosure
- Black spots spreading through the bead
