How remedial sealant works in Portsmouth
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out before the joint can be done properly. We work on leaking tray & enclosure joints, mouldy bath & shower sealant and shrunken worktop sealant, and the jobs we see most are repeat leaks from the same joint and movement joints that have split or pulled away.
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.

Remedial sealant across Portsmouth: local notes
In Portsmouth, remedial sealant takes in flats, houses, rentals and businesses, in Southsea, Milton and Landport and well beyond. Wherever the job is, all the old material comes out before anything new goes in.
The South East is one of the drier parts of the UK, but outdoor sealant still needs a dry day and clean surfaces, so outside work in Portsmouth is planned around the forecast. Along the coast in Portsmouth, holiday lets and guest houses can have bathrooms in near-constant use, so their sealant and grout wear faster than most.
Portsmouth: Rented homes near Fratton station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. If you look after a building such as Manor Infant School, we reseal washrooms and kitchens in schools and businesses as well as homes.
What we are called out for in Portsmouth
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that is too stiff or too thin.
Any of these means the joints need attention:
- Movement joints that have split or pulled away
- Leaks that keep coming back after resealing
- Over-sealed joints coming away
- Dark patches showing through the sealant
What affects the quote in Portsmouth
For a quick quote, just ask. What matters most is:
- Access and height
- The number of rooms or windows
- The old material and how stubborn it is
- The size of the job
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
What to tell us when you ask for a quote:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Where the property is
- If it’s domestic, commercial or a hotel
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
How the job changes by surface
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
Work for landlords, hotels and businesses
If you manage several properties in or around Portsmouth, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
We also work for property managers and facilities teams across Portsmouth. Several sites can go on one quote.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Cracks in the fitting rather than the joint
- Water damage behind tiles that needs a tiler
- Older mastics that may need an asbestos check before removal
