Bathroom resealing for homes and businesses in Hornchurch Marshes
The secret of a lasting bead is the preparation. The old sealant is removed to the last smear, then the joint is cleaned, degreased and treated for mould. New silicone goes on only when the joint is fully dry. If you have failed sealant on the screen profile and water getting behind the kitchen upstand, we can put it right, on wet rooms, shower trays & enclosures and sinks & splashbacks alike.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Hornchurch Marshes, that’s a good reason to put tired sealant and grout right early.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

For landlords and businesses
Landlords and letting agents in Hornchurch Marshes can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Why deal with it now?
Running new silicone over the old joint can look tidy for a few weeks, but it cannot stick to what’s underneath. It lifts, traps water and grows mould behind it, so the next person has twice as much to remove. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Why us?
- White, clear, grey or another colour, product permitting
- We never seal over old sealant
- Sanitary silicone with an anti-fungal additive in wet areas
- We agree the colour with you first

Hornchurch Marshes questions
I let a flat near Dagenham Dock station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Can parking be tricky for a visit in Hornchurch Marshes?
Parking in Hornchurch Marshes, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses.
What does bathroom resealing cost?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or email us and tell us what needs doing and where.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Do you reseal kitchen worktops and sinks too?
Yes, often alongside a bathroom. Where it’s needed by the sink, we use a food-safe sealant.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Loose or hollow tiles, or failed tanking behind them
- Cracked or missing grout between tiles (that’s regrouting)
- Movement from a bath with loose feet or no proper support
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
What we seal
- Basins & vanity units
- Shower trays & enclosures
- Sinks & splashbacks
- Wet rooms
- Baths
- Kitchen worktops & upstands
What affects the cost of bathroom resealing
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Whether the work is at height
- Any mould that needs treating
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.
Helping us quote
When you call or email, it’s useful to know:
- Where the job is, and your postcode
- Photos by email, if that’s easy
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
Signs you need bathroom resealing in Hornchurch Marshes
No sealant lasts indefinitely. Daily water, heat and cleaning products slowly wear it down, so its life depends on how the room is used, cleaned and aired.
It’s worth asking for a quote if you see:
- Black mould in the silicone that will not clean off
- A joint torn by a bath that flexes
- Two layers of silicone, both failing
- Damp behind the bath or under the tray
As a London address, Hornchurch Marshes can be tricky for parking: let us know about parking bays, permits or a driveway.

How it works
The work is kept neat and contained to the joints we are treating. The job usually takes half a day or less for one room, longer when the kitchen is included, and we tell you how long to leave it before we go. In Hornchurch Marshes, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First the area is protected and every bit of old sealant removed.
- The joint is cleaned, degreased and treated for mould.
- We let it dry fully and fill the bath with water before sealing.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We tidy up and give you the cure time, generally around 24 hours.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Bathroom resealing in Hornchurch Marshes: local notes
London has hard water, which leaves limescale on sealant, grout and taps. 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.
Schools such as Brook Sixth Form and Academy are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near Dagenham Dock station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
