Bathroom resealing for homes and businesses in Harlington
Across Harlington, the joints we reseal are the ones that fail in any home: the long edge of the bath, the base of the shower tray, the back of the basin and the line along the worktop. Every joint is cut out, cleaned and left dry before it’s resealed. We work on wet rooms, sinks & splashbacks and kitchen worktops & upstands, and people most often call us about water escaping at the shower enclosure and smears of silicone across the tiles.
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 Harlington, that’s a good reason to put tired sealant and grout right early.
Whatever the size of the job, it’s backed by our 12-month guarantee in Harlington and across Greater London.

What bathroom resealing looks like in Harlington
There are hotels and other places to stay in and around Harlington. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
Letting a property close to Heathrow Terminals 2 & 3 Rail station? Then mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. In the older streets around Church of St Peter and St Paul, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

When to call us in Harlington
Plenty of failed sealant has been laid over the top of older sealant. Fresh silicone cannot grip the old bead underneath, so it peels, leaks and hides mould behind it.
Signs it’s time to call us include:
- Cracked, shrunken or lifting silicone
- Smears of silicone across the tiles
- Black mould in the silicone that won’t clean off
- Damp behind the bath or under the tray
As a London address, Harlington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before booking
- Which colour the sealant will be
- What happens if they find a problem under the old sealant
- Are they insured?
- What product goes in the joint
Leave it or put it right?
A clean new bead makes a room look cared for, which matters if you are letting a property or selling it. A smeared, uneven DIY bead does the opposite, and it’s harder to put right later. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Harlington, the repair is bigger than the sealant job would have been.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Your questions about bathroom resealing in Harlington
Do you work for hotels and guest houses in Harlington?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Is parking a problem for a job in Harlington?
Parking in Harlington, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Can mouldy silicone be sorted out?
Yes. We strip the bead, treat the joint and lay new anti-fungal silicone.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How long does it take to reseal a bath or shower?
It takes two to three hours for a typical bath, depending on how much old sealant there is. We’ll confirm how long your job needs when we quote.
Is white the only colour available?
Most people choose white or clear, and other colours are available to suit tiles, trays and worktops. Let us know your preference when you ask for a quote.
What we do, step by step
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work usually takes around two hours for one bath or shower, longer for a whole bathroom. In Harlington, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by protecting the area and stripping out the old bead, including the film left on the tiles.
- The joint is cleaned, degreased and treated for mould.
- We let it dry fully and fill the bath with water before sealing.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- Finally we tidy up and explain the cure time before we leave.
How to prepare
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

How the job changes by surface
Kitchen worktops & upstands
Upstands and back edges are cut out, cleaned of grease and resealed, because cooking grease stops sealant bonding. Proper degreasing is what helps the new joint last.
Shower trays & enclosures
If a tray moves underfoot, new silicone will not last. Movement is checked before anything is resealed, and if the tray needs refixing, we will say so.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use gentle cleaners on the silicone
- Look for lifting corners and small gaps now and then
- Open a window or run the fan so the room dries
- Don’t leave water standing on kitchen joints
Keep bottles and razors off the sealant line, because they trap water against the silicone. Squeegeeing the walls and tray after use helps the joint dry.
Watch for the early signs: lifting ends, gaps, dark shadows under the bead or a stain downstairs. If you spot one, it’s time to reseal.
