Remedial sealant in Horsham
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and remedial work carries our 12-month guarantee. Common call-outs are for leaks that keep coming back after resealing and floor or wall movement joints that have failed, on mouldy bath & shower sealant, leaking tray & enclosure joints and shrunken worktop sealant.
A large town like Horsham has plenty of rented homes, and rented bathrooms and kitchens see heavy use. Fresh sealant and clean grout help a property present well between tenants and stop water getting where it shouldn’t.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

FAQs for Horsham
Do you work in hotels near Horsham?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Can you help a landlord with a rental near Horsham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do you work in Horsham?
Yes, we do. Horsham is part of the area we cover, and the service is the same as everywhere else.
How long will it take to strip and reseal the joint?
A little longer than a standard reseal. For most joints, it’s a few hours.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What happens if it’s left?
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. For businesses in Horsham, a room closed because of a leak or mould costs more than the sealant, so it pays to replace failing joints before they get that far.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we’re called out for in Horsham
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Any of these means the joints need attention:
- Products that weren’t meant for the joint
- A shower that leaks however often it’s resealed
- Over-sealed joints coming away
- Wide, uneven beads that look worse than the old ones
Rented homes near Horsham station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Bathrooms and kitchens in Horsham
Horsham has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
In the older streets around Hope Chapel, walls and floors in older homes can move, and sealant and grout show it first.

What else we do in Horsham
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep bleach and abrasives off the bead
- Never seal over old silicone
- Check trays and worktops don’t move
- Air the bathroom so the sealant can dry
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
If a joint has failed more than once, stop resealing it. Have someone find out why, or the next bead will go the same way.
What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Where a business in Horsham needs to stay open, out-of-hours working can be arranged, while home visits are arranged within our normal working hours, Monday to Saturday.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Let us know about parking restrictions
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in

Advice
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What the job involves on each surface
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom.
What affects the quote in Horsham

- Working hours on commercial sites
