Remedial sealant for homes and businesses in St Cross
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. We work on mouldy bath & shower sealant, botched or over-sealed joints and failed movement joints, and the jobs we see most are thick, messy sealant smeared over tiles and torn expansion joints.
Homes around St Cross range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
Each job carries a 12-month guarantee, whatever its size.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Never seal over old silicone
- Air the bathroom so the sealant can dry
- Check ceilings under showers for marks
- Deal with small splits early
Don’t let anyone seal over it later. New silicone doesn’t bond to old.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
How the visit works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. For a job in St Cross, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Common questions in St Cross
Do you work for hotels and guest houses in St Cross?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Can you help a landlord with a rental near Winchester station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Where do you work from?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Do you fix expansion and movement joints?
Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.
What the job involves on each surface
Worktops & kitchens
A loose worktop splits its sealant. That needs refixing before resealing, which we’ll point out.
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Do you need remedial sealant in St Cross?
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
It’s worth asking for a quote if you see:
- Leaks that keep coming back after resealing
- Decorators’ caulk around a bath or shower
- Thick, messy sealant smeared over tiles
- Sealant that came away because the surface wasn’t prepared
For site and facilities teams at buildings such as St Faith's Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Before you book anyone
- What insurance they hold
- Who turns up on the day
- Which colour the sealant will be
- Whether they seal over old material or remove it
What affects the cost of remedial sealant
For a quick quote, just ask. What matters most is:
- Whether the work is at height
- The number of rooms or windows
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
Asking for a quote
What to tell us when you ask for a quote:
- Whether it has been sealed before
- Roughly how big the job is
- How we’d reach the joints
- Where the property is
For a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. We will give you a clear price before any work starts.

Remedial sealant in St Cross: local notes
There are hotels and other places to stay in and around St Cross. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Letting a property close to Winchester station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For an older house near a landmark such as St. Cross Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
