Bathroom resealing in St Leonards, done properly

We’re fully insured ARBOMaster approved applicators, and the work comes with a 12-month guarantee.

Around St Leonards, it’s mostly busy family bathrooms and kitchens, which is hard on sealant and grout. Black mould along the bath, a lifting bead by the sink or crumbling grout in the shower are the usual signs.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Don’t leave water standing on kitchen joints
- Look for lifting corners and small gaps now and then
- Let new sealant cure fully before it gets wet
- Dry the bead with a towel now and then
Keep bottles and razors off the sealant line, as they hold water against it. Squeegeeing the walls and tray after use keeps water from sitting on the joint.
A few black dots in the silicone soon become a black line. Once it’s deep in the silicone, cleaning usually won’t remove it. Replacing the sealant early keeps the job small.
Bathroom resealing around St Leonards
St Leonards 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, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as St Leonard's Church of England Primary Academy are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. Rented homes near St Leonards Warrior Square station change hands often, and fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

Do you need bathroom resealing in St Leonards?
Mould is the reason many people want their sealant replaced. Steamy rooms that don’t dry out keep the silicone damp for hours, and mould that has grown into the silicone usually won’t clean off.
Look out for any of the following:
- Water getting behind the kitchen upstand
- Water getting behind the bath panel
- Lumpy, uneven sealant from a DIY attempt
- Sealant that has split, shrunk or peeled away
In the older streets around St John the Evangelist's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- How the joint is cleaned and prepared
- When the joint can take water or movement
- How the colour is chosen
- Whether they’re fully insured

What else we do in St Leonards
Different surfaces, different methods
Sinks & splashbacks
Around the sink, we use a product suited to kitchens, including a food-safe sealant where that’s needed. The joint is laid neatly so it’s easy to wipe.
Wet rooms
A wet room floor and its walls can move independently, so the corners need a flexible seal, not grout. Where grout in a corner has cracked, we can replace it with sealant.
Honest limits
To be straight with you, some problems need a different trade:
- Water getting in through the grout rather than the sealant
- Water coming from the plumbing rather than the joint
- Damage behind the tiles that needs a tiler
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Wet rooms
- Shower trays & enclosures
- Baths

What affects the quote in St Leonards
The price is agreed before any work begins. It’s based on:
- The size of the job
- Which sealant suits the joint
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before work begins.
What to tell us for a quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work before giving you a price.
Why deal with it now?
Most of the work in a good reseal happens before any silicone goes on: removing all the old sealant, degreasing the joint, treating mould and drying it properly. Skip those steps and even the best silicone fails early. In St Leonards, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a morning or an afternoon for most single baths and showers. For a job in St Leonards, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- We cover the area around the joints we are working on.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Getting ready for the visit
