Leavesden questions
Is Leavesden within the area you cover?
Yes, Leavesden is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Garston station?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Can I choose the colour of the sealant?
You’re not limited to white: white, clear and colours to suit tiles and worktops. We can help you pick when we quote.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How long does a bath or shower reseal 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.
Bathroom resealing in Leavesden, done properly
The bead of silicone around a bath, tray or worktop is what keeps water out of the gaps. When it splits, shrinks or turns black, water gets behind it and into the wall or floor. Every trace of the old sealant is taken out and replaced with anti-fungal sanitary silicone. We’re often asked to deal with gaps between the worktop and the wall and two layers of silicone, both failing, across sinks & splashbacks, kitchen worktops & upstands and baths.
Homes around Leavesden range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Bathrooms and kitchens in Leavesden
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For site and facilities teams at buildings such as Alban Wood Primary School and Nursery, we reseal washrooms and kitchens in schools and businesses as well as homes. For an older house near a landmark such as Church of All Saints, older homes can move a little, which is hard on rigid grout and tired sealant.

Looking after it afterwards
So the new joints stay in good condition:
- Run the extractor fan during and after every shower
- Wipe the sealant dry after showering
- Clean with a mild bathroom cleaner and a soft cloth
- Avoid abrasive pads on the sealant
In a kitchen, do not let water sit along the back of the worktop and keep hot pans off the bead. A dry joint lasts longer.
Watch for the early signs: lifting ends, gaps, dark shadows under the bead or a stain downstairs. Any of these means the joint needs attention.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes around two hours for one bath or shower, longer for a whole bathroom and we leave things clean and tidy. Parking around Leavesden is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First the area is protected and every bit of old sealant removed.
- We clean and degrease the joint and treat any mould.
- We let it dry fully and fill the bath with water before sealing.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We clear away and tell you when it can get wet, normally after around 24 hours.
Getting ready for the visit
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

When to call us in Leavesden
Sealant laid on a damp, dusty or greasy joint never bonds properly. Traces of soap, bath oil and old sealant stop it gripping, and a joint that looked fine soon begins to come away.
The problems people generally mention when they call include:
- Black spots spreading through the bead
- A reseal done over the top of the old bead
- Sealant that has split, shrunk or peeled away
- A joint torn by a bath that flexes
If you let a flat or house near Garston station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Different surfaces, different methods
Wet rooms
Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.
Kitchen worktops & upstands
Water behind a laminate worktop can make the edge swell. A continuous bead along the back keeps water out.
