Bathroom resealing in Letchworth Garden City, done properly
Before a bath is sealed, it’s filled with water. A full bath sits slightly lower than an empty one, so the bead is not stretched the first time someone gets in. It’s a small step that rushed reseals tend to skip. Typical jobs include a joint torn by a bath that flexes and damp behind the bath or under the tray, on sinks & splashbacks, kitchen worktops & upstands and baths.
Homes around Letchworth Garden City have been extended and refitted over the decades. A common problem is new sealant laid over old, which never bonds properly, so we take every joint back to clean before anything new goes in.
We stand behind the work with a 12-month guarantee.

What the job involves on each surface
Sinks & splashbacks
Splashbacks in glass, tile or acrylic meet the worktop in a long joint. It’s resealed in white, clear or a colour to suit.
Basins & vanity units
Vanity units have long, worktop-style joints against the wall. Water that gets behind can damage the unit, so a neat, continuous bead matters.

What sealant work can’t fix

Letchworth Garden City: your questions answered
Do you work for landlords with property near Letchworth Garden City station?
Yes. We work for landlords and letting agents as well as householders, 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 will give you a clear price.
Do you cover Letchworth Garden City for bathroom resealing?
Yes. We work across London and the South East, and Letchworth Garden City is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Do you reseal kitchen worktops and sinks too?
Yes. Where it’s needed by the sink, we use a food-safe sealant.
Is it OK to put new sealant on top of the old bead?
No, and it’s one of the main reasons reseals fail. We cut out all of the old sealant, clean the joint and start again.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long will the resealing take?
It depends on how many joints there are and how much old sealant has to come out. Allow a couple of hours for a typical bath or shower.
Can you get rid of the black mould in my sealant?
Yes. Mould inside the bead rarely cleans out for good, so the bead comes out, the joint is treated and new anti-fungal silicone goes in.
Letchworth Garden City homes and their sealant
Letchworth Garden City was laid out as a garden city in the early twentieth century. Its homes range from the original garden city houses to later estates, and bathrooms and kitchens of every age need resealing and regrouting in time. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Letchworth Garden City station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. For an older house near a landmark such as St Michael, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Stick to a soft cloth and a mild cleaner
- Wait for the cure time we give you
- Keep the fan on for a while after bathing
- Move toiletries away from the joint
Good ventilation does more than any cleaner. Run the extractor fan during and after a shower, so the silicone gets a chance to dry.
A split bead lets water through every time the bath or shower is used. Left alone, it soaks into the floor, the wall behind the tiles or the ceiling below. Early resealing closes the gap before damage is done.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take two to three hours for a typical bath, depending on how much old sealant there is, and we tell you how long to leave it before we go. Parking in a town like Letchworth Garden City is normally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- Mould is treated, then the joint is left to dry thoroughly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What we’re called out for in Letchworth Garden City
Black mould is behind a lot of resealing. Steamy rooms that don’t dry out keep the silicone damp for hours, and mould that has grown into the silicone normally will not clean off.
People generally contact us when they notice one of these:
- Black mould in the silicone that will not clean off
- A reseal done over the top of the old bead
- Water getting behind the kitchen upstand
- A bead that has pulled away from the tiles
For site and facilities teams at buildings such as Pixmore Junior School, 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.
What your quote should include
