Bathroom & kitchen resealing in Harefield, Buckinghamshire
Bathroom resealing for Harefield, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Black mould in the silicone that will not clean off
- Lumpy, uneven sealant from a DIY attempt
- Gaps between the worktop and the wall
What happens if it’s left?
You do not need a new bathroom because the sealant looks bad. Replacing the joint is generally all it takes, as long as the fittings themselves are sound. If something else is wrong, we will tell you. In a smaller place like Harefield, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear quote before work begins.
Why book with us
- Old sealant always removed completely
- Full insurance on every job
- Approved under the ARBOMaster scheme
- A 12-month guarantee on all work

Bathroom resealing for homes and businesses in Harefield
Across Harefield, the joints we reseal are the ones that fail in any home: bath edges, tray joints, basin backs and kitchen upstands. Each one is stripped, cleaned and dried before new silicone goes in. Common call-outs are for shrunken sealant along the back of a worktop and black mould in the silicone that won’t clean off, across basins & vanity units, baths and wet rooms.
Around Harefield, you’ll mostly find houses and bungalows, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Common questions in Harefield
Do you cover Harefield for bathroom resealing?
Yes. Our work covers London and the South East, and Harefield is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is Harefield within the area you cover?
Yes. Harefield is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
How long before the new sealant can get wet?
Around 24 hours is typical, and we confirm the time for the product used. Using it sooner can damage the bead.
How long will the resealing take?
It depends on how many joints there are and how much old sealant has to come out. Allow a couple of hours for a typical bath or shower.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What we’re called out for in Harefield
The wrong product fails fast. Acrylic caulk and general-purpose sealants are not designed for a joint that is wet every day, so they stain, crack or go mouldy before long. A bathroom joint needs anti-fungal sanitary silicone.
People usually contact us after spotting one of these:
- Gaps between the worktop and the wall
- Mouldy sealant that has gone black
- New sealant laid over old sealant that is now lifting
- Water getting behind the bath panel
Homes close to Harefield Baptist Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Before you book anyone
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- Are they insured?
- How hidden problems are handled
The process
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job usually takes half a day or less for one room, longer when the kitchen is included. Parking around Harefield is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We protect the area and cut out all of the old sealant, including the film left on the tiles.
- Next, the joint is cleaned and any mould is treated.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- Finally we tidy up and explain the cure time before we leave.
How to prepare
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Clean with a mild bathroom cleaner and a soft cloth
- Keep the fan on for a while after bathing
- Keep scourers and sharp tools away from the bead
- Keep bottles off the sealant line
Treat the new bead gently when you clean: a mild bathroom cleaner and a soft cloth is enough. Scourers and blades can nick the surface, because a damaged bead gives mould a foothold.
Worktop joints fail quietly. Splashes run behind the back edge and soak into the worktop, where it can make the board swell. A reseal in time can save the worktop.
