About bathroom resealing in SE13
Resealing is a small job that makes a big difference. Mouldy silicone makes even a new bathroom look neglected, and a clean white or clear joint fixes it quickly. Just as important, it closes the gaps water would otherwise get through. We work on shower trays & enclosures, baths and wet rooms, and people most often call us about a bead that has pulled away from the tiles and black mould in the silicone that won’t clean off.
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes half a day or less for one room, longer when the kitchen is included, depending on the size of the job.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- The joint is cleaned, degreased and treated for mould.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- We tool the bead to a neat finish and give you the cure time, generally around 24 hours.

Bathrooms and kitchens across SE13
Across SE13, from St Johns, Lewisham and Hither Green outwards, we see bathrooms and kitchens of every age. Family bathrooms, rented flats and hotel en suites all need their sealant and grout renewing in time.
Hard water across most of the South East leaves limescale on sealant, grout and fittings. Whatever the job in SE13, surfaces are cleaned back properly before new sealant goes in.
St Johns: For site and facilities teams at buildings such as Ashmead Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near St Johns station change hands often, and a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
What we are called out for in SE13
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.
These are the problems we’re asked about most:
- Leaks into the floor or ceiling below
- Gaps where the bath or tray has moved
- A bead that has pulled away from the tiles
- Water escaping at the shower enclosure
Surface by surface
Baths
The long joint down the side of a bath is where most leaks start, especially under a shower. We finish it with a single, even bead of anti-fungal silicone.
Shower trays & enclosures
There are normally two jobs in a shower: the tray-to-wall joint and the enclosure joints. Both take water every day, so each is cut out and renewed with anti-fungal sanitary silicone.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
If you manage several properties in or around SE13, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Avoid abrasive pads on the sealant
- Open a window or run the fan so the room dries
- Clean with a mild bathroom cleaner and a soft cloth
- Squeegee the walls and tray after use
Have a look at the joints every few months. Small splits and lifting ends are easy to catch early, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
A failed kitchen joint is easy to miss. Splashes run behind the back edge and soak into the worktop, and the board underneath can swell. Resealing before that happens protects the worktop.
SE13 questions
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover SE13, along with the rest of our area.
Does the resealing come with a guarantee?
Yes. All our work comes with a 12-month guarantee, and we’re fully insured.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is it OK to put new sealant on top of the old bead?
No, and it’s one of the main reasons reseals fail. We cut out all of the old sealant, clean the joint and start again.
How long does it take to reseal a bath or shower?
Allow a couple of hours for a single bath or shower. You will know how long to expect before we start.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
