About our remedial sealant in Burnt Oak
The wrong product in the wrong joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on expansion joints, shrunken worktop sealant and botched or over-sealed joints, and common reasons people get in touch are dark patches showing through the sealant and sealant applied over old sealant that has lifted.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.
There’s a 12-month guarantee on every job, large or small.

Signs you need remedial sealant in Burnt Oak
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
People usually contact us when they notice one of these:
- Torn expansion joints
- Leaks that keep coming back after resealing
- Thick, messy sealant smeared over tiles
- Mould trapped under a layer of silicone
Managing a site like The Annunciation RC Junior School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before you book
- What happens if the job turns out different
- Whether they seal over old material or remove it
- Who turns up on the day
- What insurance they hold
Different surfaces, different methods
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
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.

Honest limits
To be straight with you, some problems need a different trade:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Movement from fittings that aren’t supported
- Cracks in the fitting rather than the joint
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

Questions from Burnt Oak
Is parking a problem for a job in Burnt Oak?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near Mill Hill Broadway station?
Yes. We work for landlords and agents as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Can you match the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How much does remedial sealant cost in Burnt Oak?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or email us and tell us what needs doing and where.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. In Burnt Oak, 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.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Clear the area around the work

Remedial sealant around Burnt Oak
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
Burnt Oak is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For landlords with property near Mill Hill Broadway station, botched sealant from a previous quick fix is easier to strip out between tenants.

Some jobs are bigger than they look, and some smaller. The main factors:
- How many areas need sealing
- How easy the joints are to reach
- The number and length of the joints
- Any working-time requirements on site
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
