Bath resealing at your home in Gunnersbury
A reseal is a small job that makes a big difference. Clean, white joints make a bathroom look cared for, and they protect the walls and floor. We regularly repair basins & vanity units, baths and kitchen worktops & sinks, and common reasons people contact us are old sealant that looks dirty and black spots in the silicone.
Peace of mind is built in: each job carries a one-year guarantee, and we’ll explain exactly what it covers when we quote.

How to look after the repair
After the repair has cured, a few habits help it last:
- Store bottles on a shelf
- Run the extractor fan during and after showers
- Clean the sealant gently and regularly
- Wipe the joints dry after use
Avoid scraping the joints, and don’t stand bottles on the seal.
Black mould in sealant is not just unsightly, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.

Quotes are free and the price is fixed. What we look at:
- Unusual colours or finishes

Every job is a little different, so we price each one individually. What’s damaged, how badly and how easy it is to reach all make a difference, and doing several things on one visit costs less than separate visits.

FAQs for Gunnersbury
Is it worth repairing rather than replacing?
Generally, when the rest is in good condition. A repair avoids removal and making good. If replacing would be better, we’ll say so.
It’s been repaired before. Can you still fix it?
Yes, we frequently do. Removing the old work can add time, and that is in the quote.
My seal keeps tearing. Why?
Something is moving. Persistent splitting can mean the support needs attention.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Will there be a smell?
Expect a mild smell while we’re working, which fades afterwards.
Are you accredited?
We’re accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
Do I need to be at home?
Someone needs to let us in and show us the job. You don’t need to watch us work.
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.
DIY repairs versus a professional job
It’s natural to want to try a repair yourself. The trouble is that kit repairs often look fine at first and then fail, and then the old filler has to be removed first.
If you’ve already tried a DIY fix, that is fine. We take the old repair out and do it properly, so it does not stop a professional repair. It does add a little time, so tell us about it when you send pictures.
When to call us in Gunnersbury
Sealant does not last forever. Each shower leaves moisture and soap behind, which mould feeds on, and the joint flexes each time the bath fills.
It’s worth getting a quote if you see:
- Sealant that’s split or lifting
- Unsealed corners
- Damp near the bath
- Black spots in the silicone
Questions to ask before booking
- How soon you can use it again
- The length of the guarantee and what it covers
- Whether a trained technician does the job
- Whether there are any call-out or travel charges
