Mastic man in Harold Wood
With over 20 years in the trade, we reseal baths, showers and kitchens in homes across Harold Wood. We are ARBOMaster approved and fully insured, and every job carries our 12-month guarantee. We work on kitchen worktops & upstands, sinks & splashbacks and basins & vanity units, and people most often call us about gaps where the bath or tray has moved and sealant that has split, shrunk or peeled away. As mastic and silicone sealant specialists, we cover Harold Wood for bathroom resealing and other sealant work.
Bath and shower resealing is about more than looks: failed sealant lets water get behind the panel or under the tray, and that is how leaks into the room below start.
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 Harold Wood, that’s a good reason to put tired sealant and grout right early.
We stand behind the work with a one-year guarantee.

Common problems we fix in Harold Wood
Not every tube in the shop is meant for a shower. Decorators’ caulk and all-purpose sealants aren’t made for constant wetting, so they stain, crack or go mouldy before long. Wet areas call for a sanitary silicone with an anti-fungal additive.
It’s worth asking for a quote if you see:
- Leaks into the floor or ceiling below
- A joint torn by a bath that flexes
- Water escaping at the shower enclosure
- Two layers of silicone, both failing
Harold Wood is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Questions from Harold Wood
Can worn sealant in a flat in Harold Wood cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
I let a flat near Harold Wood station. Can you help?
Yes, rental work is part of what we do. You can phone 07833 053749 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
When can I use the bath or shower again?
We give you the cure time before we leave, and it’s usually around 24 hours. Using it sooner can damage the bead.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 07833 053749 or drop us an email.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
How much does bathroom resealing cost in Harold Wood?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Is the work guaranteed?
Yes. Every job carries our 12-month guarantee.
What happens if it’s left?
Sorting it now is quick: the work takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Left until water gets through, the job can grow to lifting panels, drying out and decorating. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Harold Wood, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before any work starts.

What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job generally takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen, and we explain the cure time before we leave. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We look at every joint first and check for movement or leaks.
- Every trace of the old bead is removed, including the thin smear 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, usually around 24 hours.
Before we arrive
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

Bathrooms and kitchens in Harold Wood
London’s water is hard, so limescale builds up on sealant, grout and fittings. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
For site and facilities teams at buildings such as Redden Court School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. If you let a flat or house near Harold Wood station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

Different surfaces, different methods
Basins & vanity units
Basin joints are short and close to eye level: the bead is right in front of you, so it’s tooled cleanly and evenly, finished in a colour that suits the basin.
Baths
A bath shifts slightly every time it’s filled, so it’s filled with water before the bead goes on. That way the joint is laid with the bath at its heaviest.
When it is not the sealant
To be straight with you, there are a few things sealant will not fix:
- Cracked or missing grout between tiles (that is regrouting)
- Water coming from the plumbing rather than the joint
- A cracked shower tray or bath (that needs repair or replacement)
If you’re not sure, just phone 07833 053749 or email us and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Sinks & splashbacks
- Baths
- Shower trays & enclosures
- Basins & vanity units
- Kitchen worktops & upstands
- Wet rooms
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
