Elson Remedial Sealant
Problem with your failed sealant joints in Elson? We cut out the old, prepare the joints and apply the right sealant.

- Smears and lumps from a botched reseal
- Caulk or the wrong sealant used in a wet area
Remedial sealant in Elson
Water on the floor doesn’t always mean failed silicone. 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 work on leaking tray & enclosure joints, botched or over-sealed joints and mouldy bath & shower sealant, and people most often call us about black mould underneath the bead and kitchen joints letting water behind the worktop.
Homes around Elson 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.
Every job is covered by a one-year guarantee.

What else we do in Elson
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
- Look for stains below bathrooms now and then
- Run the fan after every shower
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
If a joint has failed more than once, stop resealing it. Have someone find out why, or the next bead will go the same way.
Different surfaces, different methods
Worktops & kitchens
A loose worktop splits its sealant. That needs refixing before resealing, which we’ll point out.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, matched to the frame colour.
Why act early in Elson
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In an older home around Elson, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Remedial sealant around Elson
Elson 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. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For landlords with property near Portsmouth Harbour station, a joint that keeps failing is best fixed properly while the property is empty. For site and facilities teams at buildings such as Elson Infant School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Common problems we fix in Elson
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
The most common problems we see are:
- A shower that leaks however often it’s resealed
- Wide, uneven beads that look worse than the old ones
- Caulk or the wrong sealant used in a wet area
- Over-sealed joints coming away
Homes close to Church of St Thomas include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
How it works
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. In total, it generally takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Elson, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since 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.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Keep pets and children clear of the area while we work
