Why act early in Portslade
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out. In a smaller place like Portslade, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Why book with us
- White, clear, grey or another colour, product permitting

Remedial sealant in Portslade, done properly
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. We are often asked to deal with thick, messy sealant smeared over tiles and black mould underneath the bead, across shrunken worktop sealant, botched or over-sealed joints and expansion joints.
Smaller places like Portslade still have plenty of bathrooms that work hard every day. Older or newer, every room gets the same approach: all the old material out, the joint cleaned and dried, then new sealant or grout.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
How the job changes by surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. We rake that out where it can be removed and seal with a flexible product.
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Do you need remedial sealant in Portslade?
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
The most common problems we see are:
- Floor or wall movement joints that have failed
- Worktop sealant that has shrunk and split
- Wide, uneven beads that look worse than the old ones
- Sealant peeling off a dusty or damp surface
Letting a property close to Fishersgate station? Then a joint that keeps failing is best fixed properly while the property is empty.

What affects the quote in Portslade
You will get a clear quote before work begins. It’s based on:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Access and height
- Any mould that needs treating
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- The address or postcode of the job
- If someone has resealed it before
For a quote, call 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
What happens on the day
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Portslade, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
How to prepare
- Mention any tricky access
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

When something else is needed
In fairness, there are a few things sealant will not fix:
- A cracked shower tray or bath (that needs repair or replacing)
- A bath, tray or worktop that moves until it’s properly fixed
- Tiles that have come away from the wall
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Portslade homes and their sealant
Portslade is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around St Nicolas Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Managing a site like Peter Gladwin Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
