FAQs for Belsize
Is Belsize in your area for bathroom resealing?
Yes. Our work covers London and the South East, and Belsize is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Do you work for landlords with property near Kings Langley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
How much does bathroom resealing cost in Belsize?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Can new silicone go straight over the old?
No. Sealing over the top looks fine for a few weeks, then lifts, because silicone does not bond to silicone. Every trace of the old bead is removed first.
Bathroom resealing in Belsize
With over 20 years in the trade, we reseal baths, showers and kitchens in homes across Belsize. We are fully insured ARBOMaster approved applicators, and the work comes with a 12-month guarantee. If you’re dealing with cracked, shrunken or lifting silicone and gaps where the bath or tray has moved, we can put it right, on shower trays & enclosures, kitchen worktops & upstands and basins & vanity units alike.
Homes around Belsize are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

What else we do in Belsize
Different surfaces, different methods
Sinks & splashbacks
Water getting under the rim of an inset sink can soak the worktop. Where the sealant around the visible edge has failed, we renew it.
Shower trays & enclosures
A tray that rocks will split any sealant. We check for movement before we reseal, and if the tray needs refixing, we’ll say so.
Bathrooms and kitchens in Belsize
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Letting a property close to Kings Langley station? Then a reseal between tenants is a quick way to make the bathroom and kitchen look cared for. If you live in an older home near Church of St Paul, older homes can move a little, which is hard on rigid grout and tired sealant.

What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a morning or an afternoon for most single baths and showers for a typical job. Somewhere like Belsize needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We cover the area around the joints we are working on.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Getting ready for the visit
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Related advice
When to call us in Belsize
Not every tube in the shop is meant for a shower. Acrylic caulk and general-purpose sealants are not designed for a joint that’s wet every day, so they crack, discolour or grow mould quickly. A bathroom joint needs anti-fungal sanitary silicone.
Signs it’s time to call us include:
- Sealant that has split, shrunk or peeled away
- A messy, uneven bead from a previous reseal
- A reseal done over the top of the old bead
- Water getting behind the bath panel
Managing a site like Sarratt Church of England Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A tray or bath that is cracked through
- Tiles that have come away from the wall
- A leaking waste, trap or valve
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Give the silicone its full cure time
- Open a window or run the fan so the room dries
- Avoid abrasive pads on the sealant
- Look for lifting corners and small gaps now and then
Keep bottles and razors off the sealant line, because they trap water against the silicone. Squeegeeing the walls and tray after use helps the joint dry.
Watch for the early signs: lifting ends, gaps, dark shadows under the bead or a stain downstairs. Any of these means the joint needs attention.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
