Bath resealing in Nash, done in place
Resealing is one of the simplest ways to protect your bathroom. Old, split or mouldy sealant lets water get behind the bath or tray, and a new seal stops it. Our technicians work on kitchen worktops & sinks, basins & vanity units and shower trays & enclosures, and common reasons people get in touch are a messy previous reseal and mould you can’t clean out.
All our work comes with a one-year guarantee, wherever you are in Greater London.

Is resealing worth it?
Sealing over old silicone is a false economy. It peels within weeks, and mould stays trapped behind it. We remove the old sealant completely. Instead of hourly rates, we fix the price before we start. It depends on the damage, the material and access, and doing several items at once reduces it.

DIY kit or professional repair?
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
If you’ve already tried a DIY fix, that’s fine. We take the old repair out and do it properly, so it won’t stop us repairing it. Just mention it when you send photos, as it can add time.

Repairs by material
Baths
Baths are resealed with water in them, to open the joint fully.
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
What we do, step by step
A typical visit goes like this: we arrive at the agreed slot, protect everything around the work area, do the job and clear up. Plan for about two hours for a bath. Before leaving, we tell you when it can be used and how to look after it.
- The surrounding area is protected and the joints masked.
- Old sealant and residue are removed.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- We smooth the bead, remove the tape and leave it to cure.
Getting ready for the visit
- Mention any earlier repairs or resurfacing
- Let us know about parking or access
- Keep pets and children out of the room while we work

Your questions about bath resealing in Nash
What do you need from me?
A close-up, a wider photo and your postcode. After that, we just agree a date.
Is a repair better than a new one?
Typically, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. We’ll tell you honestly if replacement makes more sense.
Can you reseal over the old silicone?
All the old sealant comes out. New silicone won’t bond to old.
Is my repair covered?
All our work carries our one-year guarantee. We’ll explain what it covers when we quote.
Why does my sealant keep going mouldy?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
What happens after I send photos?
You get a fixed quote and available dates. If anything’s unclear, we will ask for another photo.
Do you hold any accreditations?
We’re accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
Can you redo someone else’s repair?
Generally, yes. Tell us what was done before.
When a repair isn’t the answer
Before booking, it’s worth knowing the limits too:
- Very wide gaps that need a trim
- Tiles that move, until they’re refixed
- Hidden water damage
Send us photos and we will tell you honestly before booking.

Landlords, agents and businesses in Nash
If you manage property in Nash, we will quote for several properties at once. Just send photos for each address and we’ll price them together.
Housing associations and facilities teams use us for planned and reactive repairs. A repair avoids taking out and refitting, which is easier on the people living there.
Looking after it afterwards
Nothing complicated is needed:
- Clean the joints with a mild cleaner
- Wipe the joints dry after use
- Use the extractor fan
- Reseal at the first sign of lifting
Avoid scraping the joints, and don’t stand bottles on the seal.
Black mould in sealant isn’t just unsightly, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.
