- Black spots spreading through the bead

- Water escaping at the shower enclosure
How to look after the new joints
So the new joints stay in good condition:
- Wipe up water along the back of the worktop
- Move toiletries away from the joint
- Give the silicone its full cure time
- Keep the fan on for a while after bathing
Give the silicone time to cure before it gets wet, following the cure time we give you. Once it’s cured, wiping it down after use keeps it looking new.
Don’t wait for a refit to deal with failed sealant. Sealant is a maintenance item, like the paint on a window frame, and replacing it when it fails protects the rest of the room.
Bathroom resealing in Bexleyheath, done properly
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Bexleyheath. We’re fully insured ARBOMaster approved applicators, and the work comes with a 12-month guarantee. If you have leaks into the floor or ceiling below and smears of silicone across the tiles, we can help.
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 Bexleyheath, that is a good reason to put tired sealant and grout right early.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

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 chosen for how the joint moves and where it is.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Do you need bathroom resealing in Bexleyheath?
Mould is the reason many people want their sealant replaced. Steamy rooms that don’t dry out give mould all the damp it needs, and once it has grown into the bead, cleaning rarely gets it out.
Look out for these signs:
- Two layers of silicone, both failing
- A joint torn by a bath that flexes
- Mouldy sealant that has gone black
- Leaking joints on a shower screen
If you look after a building such as Upland Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Common questions in Bexleyheath
Do you work in hotels near Bexleyheath?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can worn sealant in a flat in Bexleyheath cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How much does bathroom resealing cost in Bexleyheath?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you do kitchens as well as bathrooms?
Yes. Where it’s needed by the sink, we use a food-safe sealant.
Is the work guaranteed?
Yes. Our one-year guarantee covers every job, and we are fully insured.
How long does the new silicone need before I use the shower?
We give you the cure time before we leave, and it’s generally around 24 hours. Getting it wet too early can spoil the new joint.

Surface by surface
Baths
Baths move more than any other fitting, so we fill it with water before sealing. That way the joint is laid with the bath at its heaviest and isn’t stretched when it’s used.
Kitchen worktops & upstands
The joint between worktop and wall takes splashes, crumbs and cleaning sprays. We seal them in a colour that suits the worktop.
Bathrooms and kitchens in Bexleyheath
London’s water is hard, which leaves limescale on sealant, grout and taps. There are hotels and other places to stay in and around Bexleyheath. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Homes close to Trinity Baptist Church include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you let a flat or house near Bexleyheath station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

What happens if it’s left?
Dealing with sealant early is a short job: the work takes half a day or less for one room, longer when the kitchen is included. Wait for a leak and you may be looking at panels off, drying out and redecorating too. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Bexleyheath.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes 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. Mention any building rules, key holders or managing agents when you book.
- We protect the area and cut out all of the old sealant.
- 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 clear away and tell you when it can get wet, generally after around 24 hours.
Preparing for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
