- Gaps opening along the back of the worktop
- Smears and lumps from a botched reseal
- Sealant applied over old sealant that has lifted
Why deal with it now?
Another bead over the top won’t fix a failed joint. It does not grip the old layer, so the leak carries on and there’s now more to remove. In an older home around Hounsdown, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

- A 12-month guarantee on all work

How we handle remedial sealant in Hounsdown
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. If you’re dealing with gaps opening along the back of the worktop and mould trapped under a layer of silicone, we can put it right, on expansion joints, failed movement joints and botched or over-sealed joints alike.
Smaller places like Hounsdown still have plenty of bathrooms that work hard every day. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Hounsdown, 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 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.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Use a soft cloth, not a scourer, on silicone
- Check ceilings under showers for marks
- Keep movement joints clear of mortar and paint
- Deal with small splits early
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, phone 0345 464 0079 or drop us an email.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.
Hounsdown homes and their sealant
Hounsdown is within about 2 miles 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. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For site and facilities teams at buildings such as Hounsdown 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. Rented homes near Totton station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.
Hounsdown is about 1 mile south of Totton, in Southampton. If you need remedial sealant in Hounsdown, it’s easy to get a quote: please ring 0345 464 0079 or email us. We cover Southampton from our Crawley base, Hounsdown included. Hounsdown is one of 40 places in Southampton we cover.

What affects the quote in Hounsdown
Your quote is based on your job. We look at:
- The number and length of the joints
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- The rough size of the job
- A few photos by email, if you can
- Access, such as stairs, a lift or height
We don’t publish a price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
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.
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- A leaking trap, valve or supply pipe
- Older mastics that may need an asbestos check before removal
- A tray or bath that’s cracked
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Surfaces we seal
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Expansion joints
- Botched or over-sealed joints
- Failed movement joints
Do you need remedial sealant in Hounsdown?
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
Signs it’s time to call us include:
- Leaks that keep coming back after resealing
- Wide, uneven beads that look worse than the old ones
- Beads that never stuck properly
- Worktop sealant that has shrunk and split
For an older house near a landmark such as Colbury Christ Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- Is the old sealant removed completely?
- How hidden problems are handled
- Which sealant they’ll use, and why
- How the colour is chosen
