Common questions in Hay Street
Is there a guarantee on bathroom resealing in Hay Street?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Hay Street in your area for bathroom resealing?
Yes. We work across London and the South East, and Hay Street is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can mouldy silicone be sorted out?
Yes. Once mould has grown into the silicone, it usually can’t be cleaned out for good, so the bead comes out, the joint is treated and new anti-fungal silicone goes in.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
About our bathroom resealing in Hay Street
A shower joint gets soaked every day. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. Each gets a bead of anti-fungal sanitary silicone, finished smooth so water drains away rather than collecting. Typical jobs include a bead that has pulled away from the tiles and damp behind the bath or under the tray, on kitchen worktops & upstands, wet rooms and baths.
Around Hay Street, it’s houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
There’s a 12-month guarantee on every job.

Work for landlords, hotels and businesses
If you manage several properties in or around Hay Street, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
When to call us in Hay Street
No sealant lasts indefinitely. Every shower, every splash and every wipe with a cleaner take their toll over the years, and how long it lasts comes down to use, cleaning and ventilation.
People usually contact us when they notice something like this:
- Mouldy sealant that has gone black
- Water getting behind the bath panel
- A bead that has pulled away from the tiles
- A joint torn by a bath that flexes
Homes close to Parish Church of St Mary the Virgin include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
What to look for in a quote
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- How the surfaces are prepared before sealing

What else we do in Hay Street
How the job changes by surface
Wet rooms
In a wet room, the joints between floor and walls take standing water. They’re resealed with anti-fungal sanitary silicone, and our work is on the visible joints only.
Basins & vanity units
Basin joints are short and close to eye level: so we keep the line tidy and even, finished in a colour that suits the basin.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take around two hours for one bath or shower, longer for a whole bathroom. Somewhere like Hay Street 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.
- Protection goes down around the bath, shower or worktop.
- 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.
How to prepare
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Bathrooms and kitchens in Hay Street
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For site and facilities teams at buildings such as Jenyns First School and Nursery, we reseal washrooms and kitchens in schools and businesses as well as homes.

Leave it or put it right?
Tired sealant is not a reason to replace a bath or shower. A new bead often brings the whole room back. If something else is wrong, we’ll tell you. Where a wall is exposed, as many are in small places like Hay Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Open a window or run the fan so the room dries
- Look for lifting corners and small gaps now and then
- Use gentle cleaners on the silicone
- Dry worktop joints after washing up
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.
A failed kitchen joint is easy to miss. Splashes run behind the back edge and soak into the worktop, where it can make the board swell. Resealing before that happens protects the worktop.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
