What else we do in Blackfriars
Can I fix it myself?
DIY kits are sold for most surfaces, and they can make a small mark look better. The trouble is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair won’t last.
We understand the appeal of fixing it yourself. The trouble is that kit repairs frequently look fine at first and then fail, and then the old filler has to be removed first.
Materials and what they mean for the repair
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.
Baths
Baths are resealed with water in them, to open the joint fully.
Your questions about bath resealing in Blackfriars
Can new silicone go over old?
All the old sealant comes out. Fresh silicone does not stick to old.
How do I stop mould in sealant?
Mould needs moisture. Ventilation and drying keep it clean longer.
Can you redo someone else’s repair?
Generally, yes. We remove the old repair before doing a new one, so mention it when you send photos.
Will there be a smell?
Some materials have a smell while they’re applied, so we ventilate the room. It clears as the materials cure.
Is it OK to have pets in the house?
Yes, as long as they stay out of the room we are working in. We will let you know when it’s safe to use again.
Is it messy?
Dust sheets and masking go down before we start, and we clean up when we have finished.
Is there a call-out fee?
Travel is included in the price, with the same prices everywhere we work.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure the landlord agrees.
How to care for the repair
Simple care helps the repair last. We recommend:
- Reseal at the first sign of lifting
- Clean the sealant gently and regularly
- Run the extractor fan during and after showers
- Keep the joints dry
Good ventilation is the best protection, and wipe the joints after use to keep mould away.
Do not wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.
What we can’t put right
In fairness, some problems need a different fix:
- Water damage behind the bath that needs a builder
- Very wide gaps that need a trim
- Hollow or loose tiles

For landlords and businesses
We are used to working with agents and managing companies. Send the address, photos and access details.
We regularly price jobs from inventory or check-out pictures. That means we can quote before you even visit the property, and we can arrange access with the tenant directly if that helps.
Prices and what affects them
A fixed quote means you know the cost before booking. We look at:
- The type of damage
- Previous DIY repairs that have to come out
- Access to the area
- What the surface is made of
Set against the cost of replacement, a repair is typically a fraction of the price, because there’s no removal, plumbing or making good. Your fixed quote shows exactly what’s included.
Send pictures for a quote
Two or three clear pictures are usually enough. Try to include:
- Any earlier repairs or coatings
- Any details about the material
- One picture of the whole bath or shower
- Your postcode, so we can check dates
Getting a price is easy: snap the damage close up and then the whole item, send them to us with your postcode, and we will reply with a fixed price. Quotes are free and no obligation.
What we are called out for in Blackfriars
No sealant lasts for ever. Every bath or shower adds moisture and soap residue, which mould feeds on, and the joint flexes each time the bath fills.
Look out for any of the following:
- Silicone smeared on tiles
- Discoloured, yellow sealant
- Black mould in the sealant
- Silicone coming away from the tiles
Questions to ask before booking
- How changes to the job are handled
- What aftercare is recommended
- Whether there are any call-out or travel charges
- How soon you can use it again
The process
Here’s how a visit normally runs: we arrive on time, protect everything around the work area, do the job and tidy away. Allow a couple of hours from start to finish. Before leaving, we tell you when it can be used and what to avoid for the first few days.
- First we strip out every bit of the old mastic.
- Next we clean the joint and deal with mould.
- We dry the joint thoroughly.
- We fill a bath with water before sealing so the gap is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, including around the taps.
How to prepare
- Point us to the nearest place to park
- Make sure the area is dry
- Mention if the room is upstairs or in a flat
Ask for a price
A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, add your postcode and send them to us. What comes back is a fixed price, not a guess.
