Bathroom resealing across SE3: what to expect
Homes in SE3 have the same weak spots as anywhere else: the long edge of the bath, the base of the shower tray, the back of the basin and the line along the worktop. Each one is stripped, cleaned and dried before new silicone goes in. We’re often asked to deal with failed sealant on the screen profile and lumpy, uneven sealant from a DIY attempt, on baths, basins & vanity units and shower trays & enclosures.
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes around two hours for one bath or shower, longer for a whole bathroom for a typical job.
- We cover the area around the joints we’re working on.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
What you will pay
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Where we work in SE3
From Greenwich, Westcombe Park and Well Hall to its smaller places, homes across SE3 have bathrooms and kitchens of every age. Sealant and grout wear out in all of them, whether it’s a family bathroom, a rented flat or a hotel en suite.
Hard water across most of the South East leaves limescale on sealant, grout and fittings. Whatever the job in SE3, surfaces are cleaned back properly before new sealant goes in.
Blackheath: For site and facilities teams at buildings such as All Saints' Church of England Primary School Blackheath, 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. Blackheath is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
How the job changes by surface
Wet rooms
Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.
Basins & vanity units
The back of a basin gets wet every time someone washes. Old sealant there often goes black at the corners, so it’s cut out and renewed just like a bath joint.
Quotes for bathroom resealing in SE3
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Which sealant suits the joint
- Access and height
- Working hours on commercial sites
- The old material and how stubborn it is
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.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for property managers and facilities teams in SE3 and across Greater London. Several sites can be quoted together, and we’re fully insured.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Why it fails
Silicone needs a clean, dry surface without any grease to stick to. Traces of soap, bath oil and old sealant stop it gripping, and a joint that looked fine soon begins to come away.
The most common problems we see are:
- Splits where the tray meets the wall
- Mouldy sealant that has gone black
- Water getting behind the kitchen upstand
- New sealant laid over old sealant that is now lifting
Common questions in SE3
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Is white the only colour available?
White, clear and a range of colours are available. On a worktop we colour-match where the joint shows.
My sealant has gone black. Can you sort it?
Yes, we can. The old sealant comes out, the mould is treated, and we reseal with anti-fungal sanitary silicone.
