Bathroom resealing in Stoke Newington
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Stoke Newington. We are ARBOMaster approved and fully insured, and the work comes with a 12-month guarantee. We work on shower trays & enclosures, baths and sinks & splashbacks, and the jobs we see most are water escaping at the shower enclosure and new sealant laid over old sealant that is now lifting.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Stoke Newington, getting the joints right keeps water where it belongs and the room looking clean.
Whatever the size of the job, it’s backed by our one-year guarantee in Stoke Newington and across Greater London.

Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Stoke Newington: your questions answered
I live in a flat in Stoke Newington. Can a failed seal leak into the flat below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Do you take on hotel work around Stoke Newington?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can I choose the colour of the sealant?
You are not limited to white: clear, white and colours chosen to suit the room. We can help you pick when we quote.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you just seal over the old silicone?
No. Fresh silicone cannot stick to the old bead, so it peels away and hides mould and water. All the old sealant comes out first.
What we’re called out for in Stoke Newington
Older sealant shrinks and hardens. Along worktops it tends to pull back from the wall, opening a hairline gap that lets water and crumbs in. Heat from the hob and strong sprays speed it along.
Any of these means the joints need attention:
- A bead that has pulled away from the tiles
- A joint torn by a bath that flexes
- Failed sealant on the screen profile
- A messy, uneven bead from a previous reseal
If you let a flat or house near Stoke Newington station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a couple of hours for a single bath or shower. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Stoke Newington. It helps if you can point us to a visitor permit or a bay close to the door.
- We cover the area around the joints we are working on.
- Old sealant is sliced away and the residue removed.
- Mould is treated, then the joint is left to dry thoroughly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Preparing for the visit
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

Surface by surface
Kitchen worktops & upstands
Worktop joints get wet and wiped every day. The new bead is colour-matched where it shows.
Sinks & splashbacks
Next to the sink, the sealant has to cope with constant water, and a food-safe product where it’s needed. The bead is finished smooth so it wipes clean.
Bathrooms and kitchens in Stoke Newington
Stoke Newington has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
For an older house near a landmark such as Old Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant. If you look after a building such as St Mary's Church of England Primary School, 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.

How to look after the new joints
To keep the joints looking good and working properly:
- Give the silicone its full cure time
- Dry worktop joints after washing up
- Keep scourers and sharp tools away from the bead
- Keep an eye on the corners, where splits start
Treat the new bead gently when you clean: a mild bathroom cleaner and a soft cloth is enough. Avoid scouring pads and anything sharp, because a damaged bead gives mould a foothold.
Mould that starts as a few spots spreads through the bead. Once it’s deep in the silicone, cleaning usually won’t remove it. Replacing the sealant early keeps the job small.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
