About our remedial sealant in Holloway
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. Typical jobs include products that weren’t meant for the joint and worktop sealant that has shrunk and split, on failed movement joints, expansion joints and mouldy bath & shower sealant.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Holloway, getting the joints right keeps water where it belongs and the room looking clean.
Big or small, it’s backed by our one-year guarantee.

Remedial sealant in Holloway: local notes
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.
Holloway is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For landlords with property near Drayton Park station, a joint that keeps failing is best fixed properly while the property is empty.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep an eye on the ceiling below the bathroom
- Do not add new sealant on top of old
- Do not point over movement joints
- Keep the room well ventilated
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Holloway: your questions answered
Is parking an issue for remedial sealant in Holloway?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can you help a landlord with a rental near Drayton Park station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
How long does the work take?
The number of joints and layers decides it. You will have a timescale before any work begins.
What if the leak is not the sealant?
Then we explain what we’ve found. You may need a plumber or bathroom fitter.
What we’re called out for in Holloway
Joint depth matters. A bead bonded on three sides, or laid too thick, cannot flex, and tears at the first real movement. Backing sets the depth and stops that.
These are the problems we’re asked about most:
- Beads that never stuck properly
- Sealant applied over old sealant that has lifted
- Smears and lumps from a botched reseal
- A shower that leaks however often it’s resealed
Homes close to St Joseph and St Padarn's Church include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
Before you book anyone
- What product goes in the joint
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
- What happens if the job turns out different
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Cracks in the fitting rather than the joint
- A leaking trap, valve or supply pipe
- Sealant in an older building that needs testing for asbestos first
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Mouldy bath & shower sealant

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Holloway, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Different surfaces, different methods
Worktops & kitchens
Kitchen joints hold grease and residue, so cleaning takes longer than in a bathroom.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We say so rather than reseal.
