What bath resealing costs
A fixed quote means you know the cost before booking. We look at:
- Any earlier repairs that need removing first
- How many items we do on one visit
- The material
- How many areas need work
A repair is priced on what needs doing, not where you live. You will see the full price before booking, with nothing added on the day.
Getting a price from pictures
The better the pictures, the more accurate the price. Here’s what helps:
- A clear, close picture of the problem area
- Any earlier repairs or coatings
- A coin beside the damage so we can judge size
- The material, if you know it
Most clients in Royston get their price from pictures. Add a line about what happened and your postcode, and we will send back a fixed quote and some dates.
How we handle bath resealing in Royston
A proper reseal starts with removing every trace of the old silicone. New silicone will not bond to old, which is why many DIY jobs peel. We work on kitchen worktops & sinks, basins & vanity units and wet rooms, and the jobs we see most are discoloured, yellow sealant and unsealed corners.
You’re covered for a year from the day of the repair. Just call us if there is a problem and we will come back.

What a repair can’t fix
Not everything can be repaired, and we’ll tell you before we start. Repairs won’t solve:
- Water damage behind the bath that needs a builder
- A bath or tray that moves, until its support is fixed
- Very wide gaps that need a trim
Send us photos and we will tell you honestly before you book.
Materials we repair
- Shower trays & enclosures
- Baths
- Kitchen worktops & sinks
- Basins & vanity units
- Wet rooms
Materials and what they mean for the repair
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Baths
We fill the bath before sealing, so the joint is at its widest.
Is resealing worth it?
Putting new silicone over old doesn’t last. It peels within weeks, and mould stays trapped behind it. A proper reseal removes the old first. What it costs depends on how much damage there is and what kind, the material and how many items we do on one visit. You get a fixed price from your pictures, so there are no surprises on the day.

Do you need bath resealing in Royston?
Most reseals are because of black mould. It grows into the silicone, so cleaning only removes the surface.
People generally call us when they notice something like this:
- Missing sealant behind the taps
- Gaps in the seal
- An untidy old seal
- Black mould in the sealant

Your questions about bath resealing in Royston
Can landlords book you?
Yes, often. We quote for multiple addresses and fit around tenancy changeovers.
Is repairing better than replacing?
In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. If it is not worth repairing, we will tell you.
When can you do it?
That depends on our diary for your area. We will offer you dates when we send your quote.
Do you charge for travel?
No. Our quotes include travel, and we charge the same wherever you are.
Is it safe with children and pets around?
Just keep them out of the work area. We will let you know when it’s safe to use again.
Will the price change on the day?
The price is fixed for what the pictures show. Anything extra is discussed before we begin.
Is it messy?
Very little mess: we sheet and mask everything nearby, and we leave the room clean.
Is there any odour?
A little, depending on the job. Open windows and an extractor fan help.
Aftercare tips
To keep it looking its best for years:
- Use the extractor fan
- Reseal at the first sign of lifting
- Let steam out after showers
- Clean the sealant gently and regularly
Good ventilation is the best protection, and wipe the joints after use.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
How it works
Visits start with a quick look at the job together. Next, we cover and mask everything nearby and we start. Allow around two hours, and we’ll tell you if anything changes.
- First we strip out every bit of the old mastic.
- The joint is cleaned and any mould treated.
- The joint is dried thoroughly.
- For a bath, we fill it with water first so the joint is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, taps included.
Getting ready for the visit
- Open a window if you can
- Make sure the area is dry
- Let us know about parking or access

Work for landlords and builders
We work for landlords, letting agents and housing providers in Royston as well as householders. A repair between tenants keeps the property empty for less time, and it normally costs far less than a refit.
Housing associations and facilities teams use us for planned and reactive repairs. Repairing in place avoids the disruption of a replacement, which is easier on the people living there.
