Remedial Sealant in Gipsy Hill
Remedial sealant across Gipsy Hill and nearby, with old sealant always removed completely and a 12-month guarantee.
- A second bead peeling off the first
- Smears and lumps from a botched reseal
- Repeat leaks from the same joint
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Remedial sealant for homes and businesses in Gipsy Hill
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. We work on shrunken worktop sealant, failed movement joints and mouldy bath & shower sealant, and the jobs we see most are beads that never stuck properly and a second bead peeling off the first.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Gipsy Hill, that is a good reason to put tired sealant and grout right early.
There’s a 12-month guarantee on every job, large or small.

What the job involves on each surface
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Clean sealant with mild products only
- Keep movement joints clear of mortar and paint
- Keep the room well ventilated
- Find out why the sealant failed first
Clean gently: no scraping, scouring pads or harsh chemicals.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- Movement from fittings that are not supported
- Tiles that have come away from the wall
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Bathrooms and kitchens in Gipsy Hill
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. Gipsy Hill has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Homes close to Christ Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Schools such as Paxton Primary School are buildings too, and 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. As a London address, Gipsy Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Gipsy Hill questions
I live in a flat in Gipsy Hill. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
I let a flat near Gipsy Hill station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
How long does the work take?
A little longer than a standard reseal. Most jobs take a few hours.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
How do I get a quote for remedial sealant in Gipsy Hill?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us and tell us what needs doing and where.
Can you fix a reseal that hasn’t worked?
Yes. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.

What affects the quote in Gipsy Hill
Every job gets its own quote. These are the things that affect it:
- Working hours on commercial sites
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- Photos by email, if that is easy
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
What happens if it’s left?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Combining jobs into one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.
