- Cracked, shrunken or lifting silicone
- Shrunken sealant along the back of a worktop
- Damp behind the bath or under the tray
The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Somewhere as small as Startop's End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We cover the area around the joints we are working on.
- Old sealant is sliced away and the residue removed.
- 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.
- The joint is finished neatly and we explain when it can get wet.
How to prepare
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property

Bathroom resealing in Startop's End, done properly
Sealant is the soft line between a bath, shower or worktop and the wall. Once it cracks or goes mouldy, water starts to find its way through into walls, panels and floors. Every trace of the old sealant is taken out and replaced with anti-fungal sanitary silicone. If you are dealing with new sealant laid over old sealant that is now lifting and black spots spreading through the bead, we can put it right.
Homes around Startop's End 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: everything old comes out before the new sealant or grout goes in.
Each job carries a 12-month guarantee, large or small.

How the job changes by surface
Shower trays & enclosures
A tray that rocks will split any sealant. Movement is checked before anything is resealed, and if the tray needs refixing, we will say so.
Kitchen worktops & upstands
Water behind a laminate worktop can make the edge swell. A sound joint along the back edge stops that, as long as the worktop itself is firmly fixed.
When to call us in Startop's End
Mould is the reason many people want their sealant replaced. Bathrooms without good ventilation keep the silicone damp for hours, and once it has grown into the bead, cleaning rarely gets it out.
Most people get in touch after spotting one of these:
- Lumpy, uneven sealant from a DIY attempt
- Shrunken sealant along the back of a worktop
- Leaks into the floor or ceiling below
- New sealant laid over old sealant that is now lifting
For landlords with property near Tring station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
What your quote should include
- Is the old sealant removed completely?
- The length of the guarantee
- What product goes in the joint
- What happens if they find a problem under the old sealant
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Water getting in through the grout rather than the sealant
- A tray that rocks until it’s re-bedded
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

Bathroom resealing in Startop's End: local notes
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you look after a building such as Marsworth Church of England Infant School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of All Saints include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Startop's End is about 1 mile north of Tring, in Hertfordshire. Startop's End gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Across Hertfordshire, we cover 381 places, and Startop's End is one of them. There’s also a page for Oxford, about 25 miles away.

What’s near Startop's End
Typical jobs here are in homes near The Angler's Retreat pub and Tring School and the streets around them. For rail, the closest station is Tring station, about 2.3 miles south-east of the centre. Other landmarks nearby include Tindal Centre (5.8 miles west) and Pitstone Green Museum (1.5 miles north-east). Green spaces nearby include College Lake nature reserve and Ivinghoe Beacon.
What happens if it’s left?
Bleach and mould sprays may lighten black marks for a while, but mould that has grown into the sealant tends to return. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. In a small place like Startop's End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Startop's End: your questions answered
I let a flat near Tring station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Is Startop's End within the area you cover?
Yes. Startop's End is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. If we need more, we’ll ask.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Does the resealing come with a guarantee?
Yes, for 12 months. Looking after the joint as we suggest helps it last.
Keeping the joints in good condition
Aftercare is simple:
- Avoid abrasive pads on the sealant
- Wipe the sealant dry after showering
- Move toiletries away from the joint
- Stick to a soft cloth and a mild cleaner
In a kitchen, do not let water sit along the back of the worktop and keep hot pans off the bead. The drier the joint stays, the longer it lasts.
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.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
