North Cheam Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for householders, landlords and businesses in North Cheam. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Over-sealed joints coming away
- Kitchen joints letting water behind the worktop
- Thick, messy sealant smeared over tiles
Why deal with it now?
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing generally puts it right. If they’re not, we will tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in North Cheam, the repair is bigger than the sealant job would have been.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.
Why us?
- Anti-fungal sanitary silicone in wet areas
- Over 20 years’ experience
- You choose the colour before work begins
- Quality sealants from Arbo and Everbuild
About our remedial sealant in North Cheam
Remedial jobs in North Cheam generally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. We are often asked to deal with movement joints that have split or pulled away and products that weren’t meant for the joint, on mouldy bath & shower sealant, botched or over-sealed joints and leaking tray & enclosure joints.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In North Cheam, that is a good reason to put tired sealant and grout right early.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

What else we do in North Cheam
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Have loose fittings fixed before resealing
- Look for stains below bathrooms now and then
- Ask why a joint failed before redoing it
- Never seal over old silicone
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
Landlords, agents and businesses in North Cheam
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
The process
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work generally takes a few hours, depending on how many layers have to come out. In North Cheam, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts

Remedial sealant in North Cheam: local notes
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London’s water is hard, which leaves limescale on sealant, grout and taps.
North Cheam is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Schools such as Cheam Park Farm Primary Academy are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. If you let a flat or house near West Sutton station, botched sealant from a previous quick fix is easier to strip out between tenants.

Surface by surface
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We’ll tell you what we find.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.
What affects the quote in North Cheam
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- The size of the job
- How easy the joints are to reach
Doing several joints on one visit is generally more efficient than separate visits. We will give you a clear price for the lot.
