- Sealant peeling off a dusty or damp surface
How the visit works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before work begins. Most jobs take a few hours, depending on how many layers have to come out. For a job in Kingston, 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.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- 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.
- We give you the cure time and explain what caused the failure.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children

Advice
Remedial sealant in Kingston, done properly
Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. We work on failed movement joints, mouldy bath & shower sealant and shrunken worktop sealant, and the jobs we see most are floor or wall movement joints that have failed and repeat leaks from the same joint.
Smaller places like Kingston 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 guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Questions from Kingston
I let a flat near Fratton station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Kingston?
Yes. Kingston is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Is remedial work guaranteed?
Yes. Every job comes with our one-year guarantee.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
How do I get a quote for remedial sealant in Kingston?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or email us with a short description of the job.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
When to call us in Kingston
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould. Then the only fix is removal and a new bead.
Any of these means the joints need attention:
- Products that weren’t meant for the joint
- Floor or wall movement joints that have failed
- Smears and lumps from a botched reseal
- Repeat leaks from the same joint
If you live in an older home near Church of St Cuthbert, older homes can move a little, which is hard on rigid grout and tired sealant.
What to look for in a quote
- Whether VAT is included
- How the surfaces are prepared before sealing
- How long to leave it before use
- Whether they’re fully insured
Different surfaces, different methods
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out so the new sealant starts clean.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Why it’s worth doing now in Kingston
Ripping out a bathroom is not generally needed. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. Homes in smaller places like Kingston can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Do not wait for a small gap to become a leak
- Have loose fittings fixed before resealing
- Ask why a joint failed before redoing it
- Use a soft cloth, not a scourer, on silicone
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.
Bathrooms and kitchens in Kingston
Kingston 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, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as Miltoncross Academy are buildings too, and 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. For landlords with property near Fratton station, a joint that keeps failing is best fixed properly while the property is empty.
