About our bath resealing in Thornbury
Preparation is everything in a reseal: every bit of old silicone out, mould treated, the joint clean and dry. Then the fresh sealant goes on, as one neat, continuous bead. Whether it’s gaps in the seal and old sealant that looks dirty, we can generally put it right, whatever the material.
Every repair comes with a one-year guarantee.

Prices and what affects them
You’ll know the full cost before you book. We look at:
- The size and number of damaged areas
- The material
- Whether we combine several jobs
- Any earlier repairs that need removing first
What it costs depends on the type and amount of damage, what it’s made of 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.
Send photos for a quote
We price nearly every job from photos. This is what to send:
- Your postcode, so we can check dates
- One picture of the whole bath or shower
- Whether it’s been repaired or coated before
- What it’s made of, if you know
Getting a quote takes a couple of minutes: take one close-up and one wider shot of the bath or shower, add your postcode and send them to us. You’ll get a fixed quote, not an estimate.
Landlord and trade work in Thornbury
If you manage property in Thornbury, we will quote for several properties at once. Just send photos for each address and we’ll price them together.
Hotels, guest houses and holiday lets need rooms back in use quickly, so we keep visits short and tidy. We can work around your bookings.
What we can’t put right
Not everything can be repaired, and we’d rather say so up front. We can’t fix:
- A bath or tray that moves, until its support is fixed
- Very wide gaps that need a trim
- Loose tiles, which need refixing first
Send us photos and we’ll tell you honestly.
What we work on
- Shower trays & enclosures
- Kitchen worktops & sinks
- Baths
- Wet rooms
- Basins & vanity units
Looking after it afterwards
Looking after the surface is easy, and it makes a real difference:
- Give the seal a regular clean
- Run the extractor fan during and after showers
- Wipe the joints dry after use
- Air the room after use
Avoid scraping the joints, and do not stand bottles on the seal.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. It may be more than a reseal, so we’ll tell you if it needs a builder or plumber.
What we do, step by step
Once we are through the door, we keep the work contained to the one room. Surfaces nearby are masked off, the work takes about two hours for a bath, and we finish with a tidy-up and a look at the finished work together.
- We protect the area and mask the joint lines.
- Old sealant and residue are removed.
- The joint is cleaned, treated and dried.
- We run a continuous bead of new silicone.
- The bead is smoothed, the tape removed and the seal left to cure.
Before we arrive
- Move bottles, mats and clutter away from the area
- Have somewhere for us to park nearby if possible
- Let the surface dry out before the visit

Related advice
Is resealing worth it?
Sealing over old silicone is a false economy. It peels within weeks, and mould stays trapped behind it. A proper reseal removes the old first. A repair typically costs much less than people expect, especially compared with replacing and refitting. Photos let us give you the exact figure.
What you get with us
- One-year guarantee on every repair

Common questions in Thornbury
How do I get a price for bath resealing in Thornbury?
The exact price depends on the damage, so we quote from photos. You will get a fixed figure before you book.
Can you redo someone else’s repair?
Generally, yes. Tell us what was done before.
Do you work in Thornbury?
We do. Repair technicians travel to Thornbury from across the region, with no extra charge for travel.
What happens if you find more damage?
We’ll show you and explain before doing anything extra. Nothing extra is done without your say-so.
Can you reseal over the old silicone?
Never over old. The old sealant is cut out and the joint cleaned and dried.
Is repairing better than replacing?
Usually, when the rest is in good condition. A repair avoids removal and making good. If replacing would be better, we’ll say so.
Can I add another job to the visit?
Yes. Combining jobs on one visit brings the cost down. Send photos of everything you’d like done.
How quickly can you book me in?
Your quote comes with available dates. Tell us if you need it done quickly.
Should I try a DIY kit first?
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
A DIY attempt isn’t a disaster. We take the old repair out and do it properly, so it doesn’t stop a professional repair. Just mention it when you send pictures, as it can add time.
