Remedial sealant for homes and businesses in Shepherd's Bush
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and remedial work carries our one-year guarantee. We work on leaking tray & enclosure joints, failed movement joints and shrunken worktop sealant, and common reasons people get in touch are decorators’ caulk around a bath or shower and wide, uneven beads that look worse than the old ones.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Shepherd's Bush, that’s a good reason to put tired sealant and grout right early.
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.

Keeping the joints in good condition
Looking after new joints is easy:
- Have loose fittings fixed before resealing
- Clean sealant with mild products only
- Do not wait for a small gap to become a leak
- Do not point over movement joints
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, call 0345 464 0079 or email us.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.
How the job changes by surface
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath, and then we reseal it neatly.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
When it is not the sealant
Before booking, it’s worth knowing the limits:
- A leaking trap, valve or supply pipe
- Cracks in the fitting rather than the joint
- Sealant in an older building that needs testing for asbestos first
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.
Surfaces we seal
- Botched or over-sealed joints

Shepherd's Bush: your questions answered
Can parking be tricky for a visit in Shepherd's Bush?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you work for landlords with property near Shepherds Bush station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Do you cover Shepherd's Bush?
Yes. We cover Shepherd's Bush, as part of our work across South East England, London and Scotland. To book, phone 0345 464 0079 or email us.
Where is Mr Mastic based?
We work from Crawley. We cover Shepherd's Bush and the rest of Greater London, along with the rest of our area.
Can you take off two layers of silicone?
Yes. Both layers come out; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.

Signs you need remedial sealant in Shepherd's Bush
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
Keep an eye out for these signs:
- A shower that leaks however often it’s resealed
- Wide, uneven beads that look worse than the old ones
- Gaps opening along the back of the worktop
- Dark patches showing through the sealant
Schools such as Addison Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Before you book anyone
- Whether they’re fully insured
- Is VAT in the price?
- What happens if they find a problem under the old sealant
- What product goes in the joint
Landlord and commercial work in Shepherd's Bush
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours, depending on how many layers have to come out. In a London area like Shepherd's Bush, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
