Remedial sealant in Portsmouth
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. If you are dealing with sealant peeling off a dusty or damp surface and caulk or the wrong sealant used in a wet area, we can help.
Lots of homes in Portsmouth are rented, and bathrooms in rentals work hard. Sorting the joints between tenancies keeps leaks at bay and makes a property easier to let.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Questions from Portsmouth
Can you do remedial sealant in Portsmouth?
Yes, Portsmouth is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you work for hotels and guest houses in Portsmouth?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Can you reseal a split movement joint?
Yes. Backing sets the depth and stops the sealant sticking to the back.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. First we check whether the leak is the sealant at all, then strip and reseal the joints.
Can old silicone be taken off without scratching the tiles?
Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
What happens if it’s left?
Ripping out a bathroom is not generally needed. If the bath, tray and tiles are sound, remedial resealing generally puts it right. Where something else has failed, you’ll hear it from us. In a large rental market like Portsmouth, tired sealant leads to tenant complaints about mould, damp and leaks. Sorting it between tenancies is easier than dealing with it mid-let.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Different surfaces, different methods
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We will tell you what we find.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and point out any existing damage.
DIY versus a professional finish
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: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Plumbing leaks behind walls or under trays
- Movement from fittings that aren’t supported
- Cracks in the fitting rather than the joint
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Advice
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Remedial sealant around Portsmouth
Portsmouth is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
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, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Do you need remedial sealant in Portsmouth?
Movement tears sealant that is not designed for it. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
People usually contact us when they notice something like this:
- Mould trapped under a layer of silicone
- Sealant applied over old sealant that has lifted
- Kitchen joints letting water behind the worktop
- Products that weren’t meant for the joint
In the older streets around St Wilfrid, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
