  • A cracked shower tray or bath (that needs repair or replacement)
  • A leaking waste, trap or valve
  • Movement from a bath with loose feet or no proper support

If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

Bathroom resealing in Balham

A bead that has gone black, split or come away is worth sorting before it lets water through. Just ring 0345 464 0079 or drop us an email with a photo of the joints, and you will get a clear quote for bathroom resealing in Balham. Common call-outs are for a messy, uneven bead from a previous reseal and sealant that has split, shrunk or peeled away, across basins & vanity units, baths and sinks & splashbacks.

Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Balham more than a cosmetic job.

You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What happens if it’s left?

The difference in a professional reseal is mostly what you do not see: cutting out every trace of the old bead, cleaning, treating mould and letting the joint dry. Skip those steps and even the best silicone fails early. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Bathroom resealing in Balham: local notes

In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London has hard water, which leaves limescale on sealant, grout and taps.

As a London address, Balham can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Balham station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. For site and facilities teams at buildings such as Ravenstone Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the visit works

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We cover the area around the joints we’re working on.
  2. We cut away the old sealant and clean off what’s left.
  3. We treat any mould and let the joint dry properly.
  4. Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
  5. The joint is finished neatly and we explain when it can get wet.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any leaks or damp you’ve noticed
  • Mention any sign-in or site rules at work premises

FAQs for Balham

Is parking a problem for a job in Balham?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

I let a flat near Balham station. Can you help?

Yes. We work for landlords and letting agents as well as homeowners. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.

Is it OK to put new sealant on top of the old bead?

No, and it’s one of the main reasons reseals fail. The old joint is stripped, cleaned and resealed from scratch.

Will you leave a mess?

No. We work neatly, protect the area around the joints and tidy up afterwards.

Do you have insurance?

Yes. Mr Mastic is fully insured.

Do the sealants smell?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Is it worth trying it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Will the old sealant be removed?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What the job involves on each surface

Kitchen worktops & upstands

Upstands and back edges are cut out, cleaned of grease and resealed, since cooking leaves a film that stops silicone sticking. The extra cleaning is what makes the bead last.

Shower trays & enclosures

A tray that rocks will split any sealant. Movement is checked before anything is resealed, and if the tray needs refixing, we’ll say so.
