About our remedial sealant in Moor Park
Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. Common call-outs are for sealant peeling off a dusty or damp surface and thick, messy sealant smeared over tiles, on expansion joints, mouldy bath & shower sealant and botched or over-sealed joints.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Moor Park, getting the joints right keeps water where it belongs and the room looking clean.
Every job comes with our 12-month guarantee, wherever you are in Greater London.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

What affects the quote in Moor Park
Call for a quick quote. The main things that affect it are:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- The number and length of the joints
- Which sealant suits the joint
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Photos by email, if that’s easy
- The address or postcode of the job
- What’s wrong with the joints now
- Any previous sealing or DIY work
Getting a quote is simple: let us know what needs doing and where. A few photos by email make the job easier to understand.
How to look after the new joints
After the cure time, these simple habits help:
- Don’t wait for a small gap to become a leak
- Run the fan after every shower
- Use a soft cloth, not a scourer, on silicone
- Get the cause of a repeat leak found before resealing
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, call 0345 464 0079 or email us.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Moor Park. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Clear the area around the work
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

Common questions in Moor Park
Is parking an issue for remedial sealant in Moor Park?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near Rickmansworth station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
Are you fully insured?
Yes. Full insurance covers our work.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How do I get a quote for remedial sealant in Moor Park?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or drop us an email with a short description of the job.
Different surfaces, different methods
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing stops that, letting the sealant flex between the two faces.
Why it’s worth doing now in Moor Park
Another bead over the top will not fix a failed joint. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Moor Park.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Why choose Mr Mastic in Moor Park
- White, clear, grey or another colour, product permitting
- Any old sealant cut out fully, not covered over
- An ARBOMaster approved applicator
- Colour picked to suit the job
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A cracked shower tray or bath (that needs repair or replacing)
- Failed tanking or loose tiles behind the sealant
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Failed movement joints
- Botched or over-sealed joints

- Leaking tray & enclosure joints

Moor Park homes and their sealant
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. London’s water is hard, which leaves limescale on sealant, grout and taps.
For landlords with property near Rickmansworth station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For an older house near a landmark such as Holy Trinity Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you look after a building such as St Martins School Northwood, we reseal washrooms and kitchens in schools and businesses as well as homes.
