Remedial sealant in Swaythling
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you ring 0345 464 0079 or drop us an email, along with when it was last resealed. We work on failed movement joints, mouldy bath & shower sealant and leaking tray & enclosure joints, and people most often call us about sealant applied over old sealant that has lifted and leaks that keep coming back after resealing.
Homes around Swaythling 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.

What remedial sealant looks like in Swaythling
There are hotels and other places to stay in and around Swaythling. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Managing a site like Mansbridge Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St. Mary's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

How the job changes by surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath, and then we reseal it neatly.
What affects the quote in Swaythling
We quote each job individually. These are the things that affect it:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- Access and height
- The size of the job
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
What to tell us for a quote
When you contact us, it’s useful to know:
- The address or postcode of the job
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property

How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. In a smaller place like Swaythling, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We protect the surfaces around the joint.
- 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.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed

Related advice
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Act on a lifting corner right away
- Keep movement joints clear of mortar and paint
- Always have old sealant cut out, not covered
- Get the cause of a repeat leak found before resealing
Where we’ve pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Why deal with it now?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a smaller place like Swaythling, 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.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What else we do in Swaythling
Common problems we fix in Swaythling
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
It’s worth asking for a quote if you see:
- A shower that leaks however often it’s resealed
- Sealant that came away because the surface wasn’t prepared
- Thick, messy sealant smeared over tiles
- Torn expansion joints
For landlords with property near Swaythling station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
What your quote should include
- How much experience the applicator has
- What insurance they hold
- How hidden problems are handled
- How the colour is chosen
When it isn’t the sealant
To be straight with you, some problems need a different trade:
- A bath, tray or worktop that moves until it’s properly fixed
- Cracks in the fitting rather than the joint
- Tiles that have come away from the wall
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.
