Bath resealing at your home in Furnace
Baths are resealed with water in them, so the joint is at its widest, which stops the new seal tearing the first time the bath is used. We regularly repair baths, wet rooms and basins & vanity units, and common reasons people contact us are gaps by the taps and black spots in the silicone.
Whatever the size of the job, you get the same one-year guarantee.

Landlord and trade work in Furnace
For developers and builders, we fix damage before handover, saving last-minute replacements. Several plots can be done in one visit.
Landlords, letting agents and housing providers in Furnace use us as well as householders. A repair between tenants keeps the property empty for less time, and it costs much less than replacing.
Keeping it looking good
Looking after the surface is easy:
- Give the seal a regular clean
- Wipe the joints dry after use
- Ventilate the bathroom well
- Open a window after bathing
Good ventilation is the best protection, and wipe the joints after use to keep mould away.
Black mould in sealant is not just unsightly, it’s a sign moisture is sitting in the joint. Resealing early keeps water out of the walls and floor.
Resealing in Furnace: why it matters
Resealing is routine maintenance. Leaving split or mouldy sealant can let water reach the walls and floor, which costs far more to put right. Instead of hourly rates, we price the whole job up front. Damage, material and access decide it, and doing several items at once reduces it.

How we price bath resealing
You will know the full cost before you book. We take into account:
- The type of damage
- Where the damage is and how we get to it
- What the surface is made of
- Whether we combine several jobs
Set against the cost of replacement, repairing generally costs far less, because there’s no removal, plumbing or making good. Your fixed quote shows exactly what’s included.
Getting a price from photos
When you take your photos, these tips help us give you a firm price:
- A wider photo showing the whole bath or shower
- A coin or ruler next to the damage for scale
- The postcode, so we can plan the visit
- Any details about the material
For most jobs, photos are all we need to give you a price. Add a line about what happened and your postcode, and we’ll reply with a fixed quote and the earliest dates we have.
What your bath or shower is made of matters
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Baths

Common questions in Furnace
Are you accredited?
Yes, including CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.
Is it safe with children and pets around?
On the day, the room should be kept clear of pets and children, so the repair is not disturbed while it cures.
Can landlords book you?
Yes, frequently. We can quote for several properties together and work between tenancies.
How long does silicone take to cure?
You will get the curing time from us, generally around a day.
Why does my sealant keep going mouldy?
Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.
Is it worth repairing rather than replacing?
Normally, when the rest is in good condition. A repair avoids removal and making good. If replacing would be better, we will say so.
Is there a guarantee?
Yes, for a year. If there’s a problem with the work in that time, we come back and put it right.
Can tenants book a repair?
Of course. Check with your landlord; we can send the quote to them too.
The process
We turn up at the time we agreed with you and checks the damage against your photos first. The floor and nearby surfaces are covered before any work starts. The work itself takes around two hours, and the room is left clean and tidy.
- All the old sealant is cut out and removed.
- The joint is cleaned and any mould treated.
- We ensure the joint is completely dry.
- We fill a bath with water before sealing so the gap is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.
How to prepare
- Let us know which floor the room is on
- Tell us about any previous repairs or coatings
- Keep children and pets away from the room on the day
Ask for a price
The quickest way to a price is to send a couple of pictures using our quote form or call us. We’ll tell you honestly if a repair is the right fix.
