Bathroom resealing in Upton
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Upton. We’re ARBOMaster approved and fully insured, and every job carries our 12-month guarantee. Common call-outs are for black spots spreading through the bead and failed sealant on the screen profile, across sinks & splashbacks, baths and kitchen worktops & upstands.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Upton, bathroom resealing is as much about a room looking cared for as about keeping water out.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about bathroom resealing in Upton
Is parking a problem for a job in Upton?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
I let a flat near Forest Gate station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How do I get a quote for bathroom resealing in Upton?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or drop us an email and tell us what needs doing and where.
Can you reseal around my kitchen sink and worktop?
Yes. We reseal worktop upstands, sinks and splashbacks, with a sealant suited to kitchens, colour-matched where it shows.
How long does it take to reseal a bath or shower?
One bath or shower is around two hours’ work, including cutting out the old sealant. A full bathroom and kitchen can take most of a day.
How long does the new silicone need before I use the shower?
The surface skins over fairly quickly, but the bead needs longer to cure right through. Keep water off it for around 24 hours, or as long as we advise for that product.
Can you just seal over the old silicone?
No, and it’s one of the main reasons reseals fail. The old joint is stripped, cleaned and resealed from scratch.
Landlords, agents and businesses in Upton
Housing providers, facilities teams and property managers book us too in Upton and across Greater London. We can quote a run of properties together, and we’re fully insured.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Look for lifting corners and small gaps now and then
- Keep bottles off the sealant line
- Do not leave water standing on kitchen joints
- Keep the fan on for a while after bathing
Give the silicone time to cure before it gets wet, following the cure time we give you. Once it’s cured, wiping it down after use keeps it looking new.
Mould that starts as a few spots spreads through the bead. When it has grown right through, it rarely cleans out. Replacing the sealant early keeps the job small.
When to call us in Upton
Sealant laid on a damp, dusty or greasy joint never bonds properly. Soap residue, oils and leftover silicone film all get in the way, so a rushed job can start to lift early.
The problems people normally mention when they call are:
- Gaps where the bath or tray has moved
- Failed sealant on the screen profile
- Damp behind the bath or under the tray
- Black mould in the silicone that won’t clean off
Schools such as Elmhurst Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What else we do in Upton
Upton homes and their sealant
Upton has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to St Peter's Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Upton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What affects the quote in Upton
You’ll get a clear quote before any work starts. It’s based on:
- Whether the work is at height
- The product the joint needs
- How many areas need sealing
- The size of the job
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Helping us quote
To help us quote quickly, please include:
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- Whether it’s a home or a business
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, call 0345 464 0079 or email us.
How the visit works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes two to three hours for a typical bath, depending on how much old sealant there is. In Upton, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We cover the area around the joints we are working on.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- The joint is finished neatly and we explain when it can get wet.
Before we arrive
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Mention any tricky access
How to get a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Advice
Different surfaces, different methods
Baths
Baths move more than any other fitting, so it’s filled with water before the bead goes on. That way the joint is laid with the bath at its heaviest.
Kitchen worktops & upstands
Water behind a laminate worktop can make the edge swell. A continuous bead along the back keeps water out.
Honest limits
We won’t take on work that won’t last, so these are the limits:
- Cracks in the tray itself rather than the joint
- Loose or hollow tiles, or failed tanking behind them
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
