How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a morning or an afternoon for most single baths and showers. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First, each joint is checked for movement and signs of water.
- The old silicone is cut out completely, along with the film it leaves 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.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions

Advice
Bathroom resealing in Walthamstow
A bead that has gone black, split or come away is worth sorting before it lets water through. Just call 0345 464 0079 or drop us an email with a photo of the joints, and we’ll give you a clear price for bathroom resealing in Walthamstow. We work on baths, shower trays & enclosures and kitchen worktops & upstands, and people most often call us about gaps between the worktop and the wall and splits where the tray meets the wall.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout.
Big or small, it’s backed by our 12-month guarantee.

Signs you need bathroom resealing in Walthamstow
The wrong product fails fast. Acrylic caulk and general-purpose sealants are not designed for a joint that’s wet every day, so they crack, discolour or grow mould quickly. A bathroom joint needs anti-fungal sanitary silicone.
The most common problems we see are:
- Gaps where the bath or tray has moved
- A messy, uneven bead from a previous reseal
- Water escaping at the shower enclosure
- Leaks into the floor or ceiling below
For landlords with property near Walthamstow Central station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

Your questions about bathroom resealing in Walthamstow
Do you work for landlords with property near Walthamstow Central station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Could a tired shower seal in my Walthamstow flat affect the neighbours 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.
Can mouldy silicone be sorted out?
Yes, we replace the mouldy bead. Cleaning products may lighten it, but the lasting fix is new anti-fungal silicone on a clean, treated joint. Good ventilation helps keep it away.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Is it OK to put new sealant on top of the old bead?
No, never. A bead laid over old silicone soon starts to come away. Every trace of the old bead is removed first.
How much does bathroom resealing cost in Walthamstow?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Is the work guaranteed?
Yes. We give a 12-month guarantee on every job, and we’re ARBOMaster approved applicators.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Surface by surface
Basins & vanity units
Vanity units have long, worktop-style joints against the wall. Water that gets behind can damage the unit, so a neat, continuous bead matters.
Wet rooms
Wet rooms rely on sound joints at floor and wall junctions. They’re resealed with anti-fungal sanitary silicone, and our work is on the visible joints only.

Why act early in Walthamstow
The difference in a professional reseal is mostly what you do not see: removing all the old sealant, degreasing the joint, treating mould and drying it properly. Skip those steps and even the best silicone fails early. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why book with us
- Domestic, commercial and hotel work
- White, clear, grey or coloured to suit, where the product allows
- Every job guaranteed for a year
- Anti-fungal silicone where joints get wet

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep the fan on for a while after bathing
- Dry worktop joints after washing up
- Clean with a mild bathroom cleaner and a soft cloth
- Move toiletries away from the joint
Wipe up standing water along the worktop joint and keep hot pans away from the silicone. A dry joint lasts longer.
Small signs come before a leak: a corner lifting, a gap behind the bead, a dark line under the silicone or a damp patch on the ceiling below. Any of these means the joint needs attention.
What bathroom resealing looks like in Walthamstow
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
As a London address, Walthamstow can be tricky for parking: let us know about parking bays, permits or a driveway. If you look after a building such as Greenleaf Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
