Silicone sealant specialist in Harold Hill
Across Harold Hill, the joints we reseal are the ones that fail in any home: bath edges, tray joints, basin backs and kitchen upstands. Every joint is cut out, cleaned and left dry before it’s resealed. We work on shower trays & enclosures, wet rooms and kitchen worktops & upstands, and the jobs we see most are damp behind the bath or under the tray and black mould in the silicone that won’t clean off. Whether you’re looking for a mastic man, a sealant applicator or a sealant company in Harold Hill, Mr Mastic can help.
Whether it’s a bath reseal, a shower reseal or the whole bathroom, the method in Harold Hill is the same: every bit of old silicone out, mould treated, and a fresh bead of anti-fungal sanitary silicone.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Harold Hill, getting the joints right keeps water where it belongs and the room looking clean.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a couple of hours for a single bath or shower and we leave things clean and tidy. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Harold Hill. A visitor permit or a nearby bay makes the visit run more smoothly.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts

Advice
What bathroom resealing looks like in Harold Hill
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London’s water is hard, which leaves limescale on sealant, grout and taps.
As a London address, Harold Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as St Paul, older homes can move a little, which is hard on rigid grout and tired sealant. Managing a site like Drapers' Pyrgo Priory School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

FAQs for Harold Hill
Do you work for landlords with property near Harold Wood station?
Yes, rental work is part of what we do. Just call 07833 053749 or send us an email and tell us about the property, and we will give you a clear price.
I live in a flat in Harold Hill. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.

What else we do in Harold Hill
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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How to look after the new joints
To keep the joints looking good and working properly:
- Open a window or run the fan so the room dries
- Dry worktop joints after washing up
- Look for lifting corners and small gaps now and then
- Do not let bottles sit on the bead
Mould needs damp, so keep the room aired. Use the fan, or open a window, while you bathe and for a while afterwards, so the bead dries out between uses.
Do not wait for a refit to deal with failed sealant. Sealant is a maintenance item, like the paint on a window frame, and renewing it as soon as it fails protects everything around it.
Why act early in Harold Hill
Running new silicone over the old joint can look tidy for a few weeks, but it will not bond. Water creeps under it and mould follows, so the next person has twice as much to remove. 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 Harold Hill, the repair is bigger than the sealant job would have been.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Different surfaces, different methods
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.
Sinks & splashbacks
Water getting under the rim of an inset sink can soak the worktop. Where the sealant around the visible edge has failed, we renew it.
