About our bathroom resealing in Shirley
Sealant is the soft line between a bath, shower or worktop and the wall. When it splits, shrinks or turns black, water gets behind it and into the wall or floor. Our team cut the old bead out completely and lay a new one in anti-fungal sanitary silicone. If you have a reseal done over the top of the old bead and cracked, shrunken or lifting silicone, we can help, on shower trays & enclosures, wet rooms and sinks & splashbacks alike.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.
A 12-month guarantee comes as standard.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

What else we do in Shirley
The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a couple of hours for a single bath or shower, including the tidy-up. In Shirley, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by protecting the area and stripping out the old bead.
- Next, the joint is cleaned and any mould is treated.
- We let it dry fully and fill the bath with water before sealing.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We tidy up and give you the cure time, generally around 24 hours.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks

Advice
Signs you need bathroom resealing in Shirley
Not every tube in the shop is meant for a shower. Acrylic caulk and general-purpose sealants aren’t designed for a joint that’s wet every day, so they stain, crack or go mouldy before long. A bathroom joint needs anti-fungal sanitary silicone.
Most people get in touch after spotting one of these:
- Failed sealant on the screen profile
- Shrunken sealant along the back of a worktop
- Sealant that has split, shrunk or peeled away
- Smears of silicone across the tiles
As a London address, Shirley can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Questions from Shirley
Is parking a problem for a job in Shirley?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can you help a landlord with a rental near Elmers End station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Do you do kitchens as well as bathrooms?
Yes. Worktops, sinks and splashbacks are all part of the job, with a sealant suited to kitchens, colour-matched where it shows.
Can I choose the colour of the sealant?
White and clear are the most common choices, and other colours are available to suit tiles, trays and worktops. Tell us what you’d like when you get in touch.
Can mouldy silicone be sorted out?
Yes, we replace the mouldy bead. Sprays can fade the marks, but cutting it out and resealing is what lasts. Good ventilation helps keep it away.
When can I use the bath or shower again?
Silicone is touch-dry quite quickly, but it takes longer to cure. Leave it around 24 hours before it gets wet, or as long as we advise for that product.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
What we cannot put right
It helps to know what we can’t do:
- A tray or bath that is cracked through
- Water coming from the plumbing rather than the joint
- Water getting in through the grout rather than the sealant
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
What we seal
- Basins & vanity units

Bathroom resealing around Shirley
London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. 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.
Schools such as Oasis Academy Shirley Park are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St George The Martyr Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What the job involves on each surface
Baths
Baths move more than any other fitting, so it’s filled with water before the bead goes on. The joint is then laid with the bath at its lowest point and is not torn the first time it’s used.
Basins & vanity units
Basins take less water than showers, but the joint behind them is splashed every day. Old sealant there often goes black at the corners, and we treat it exactly as we would a bath.
What affects the cost of bathroom resealing
Every job gets its own quote. This is what makes a difference:
- The number of rooms or windows
- Which sealant suits the joint
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
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 the work is at height. We take all of that into account in your quote.
Asking for a quote
When you call or email, these details help:
