Remedial sealant & repairs in Plaistow, Greater London
Our applicators work in Plaistow on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a 12-month guarantee.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
About our remedial sealant in Plaistow
Remedial jobs in Plaistow generally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on leaking tray & enclosure joints, shrunken worktop sealant and botched or over-sealed joints, and people most often call us about worktop sealant that has shrunk and split and products that weren’t meant for the joint.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Plaistow more than a cosmetic job.
Whatever the size of the job, you get the same 12-month guarantee.

The process
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. For a job in Plaistow, 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.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

Advice
What we can’t put right
It helps to know what we cannot do too:
- Water damage behind tiles that needs a tiler
- A bath, tray or worktop that moves until it’s properly fixed
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
What we seal
- Expansion joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Failed movement joints
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Clean sealant with mild products only
- Don’t point over movement joints
- Deal with small splits early
- Always have old sealant cut out, not covered
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.
Remedial sealant around Plaistow
There are hotels and other places to stay in and around Plaistow. Hotel bathrooms are part of our work as well as homes, and can be done room by room. 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.
If you live in an older home near Memorial Community Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Plaistow is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Plaistow questions
Could a tired shower seal in my Plaistow flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Do you work for hotels and guest houses in Plaistow?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours, and we confirm the time with your quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Do you cover Plaistow?
We do. Plaistow is part of the area we cover.
What if the leak is not the sealant?
That’s why we look for the cause first. If we find the leak is elsewhere, we tell you before going further.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you need remedial sealant in Plaistow?
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
If you can see any of these, it’s time to have the joints looked at:
- Over-sealed joints coming away
- Sealant that came away because the surface wasn’t prepared
- Dark patches showing through the sealant
- Wide, uneven beads that look worse than the old ones
Letting a property close to West Ham station? Then a joint that keeps failing is best fixed properly while the property is empty.
What your quote should include
- The length of the guarantee
- How the colour is chosen
- Whether the sealant suits the joint
- Are they insured?
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
