Bath Resealing in Welwyn
Fixed-price bath resealing in Welwyn and the surrounding area, done in a single visit in most cases.
- Missing sealant behind the taps
- Mould you can’t clean out
- Damp near the bath
DIY repairs versus a professional job
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.
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. It does add a little time, so tell us about it when you send pictures.
Bath resealing in Welwyn without replacing anything
We reseal baths, shower trays, basins and worktops using mould-resistant silicone. Most jobs take a couple of hours. We are frequently asked to fix leaks at the edges and gaps in the seal, on kitchen worktops & sinks, shower trays & enclosures and basins & vanity units.
Every job is backed for twelve months in Welwyn and everywhere else. We return to put right any problem with the work.

Work for landlords and builders
For developers and builders, we fix damage before handover, saving last-minute replacements. Several plots can be done in one visit to keep costs down.
Builders, developers and site managers book us for snagging repairs, fixing chips and scratches before handover. We’re CHAS, Constructionline and SafeContractor accredited.

Signs you need bath resealing in Welwyn
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.
Keep an eye out for these signs:
- Silicone smeared on tiles
- Unsealed corners
- Leaks at the edges
- Sealant that is split or lifting
Before you book anyone
- Is the price fixed, and does it include VAT?
- What protection goes down before work starts
- What the guarantee covers, and for how long
- Whether the colour is mixed to match

When a repair isn’t the answer
Not everything can be repaired, and we will tell you before we start. Repairs won’t solve:
- Loose tiles, which need refixing first
- 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.

Why reseal now?
Sealing over old silicone is a false economy. It peels within weeks, and traps mould underneath. A proper reseal removes the old first. A repair is priced on what needs doing, not where you live. You will see the full price before you book, with nothing added on the day.
What you get with us
- CHAS, Constructionline and SafeContractor accredited
- No extra charge for your area
- Work done at your home or business
- One visit for most repairs

What we do, step by step
On the day, we arrive at the time we’ve agreed, cover the area with dust sheets and masking, and set to work. Expect it to take around two hours. We clean up when we are done and tell you when it’s ready to use.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- The bath is filled with water, or weight put on the tray.
- New mould-resistant silicone is applied and tooled neatly.
Before we arrive
- Avoid using the area for a few hours before we arrive
- Mention if the room is upstairs or in a flat
- Make sure the room can be ventilated
Getting a price

How to care for the repair
It’s all simple stuff, just a few sensible habits:
- Use the extractor fan
- Replace the seal when mould sets in
- Air the room after use
- Clean the sealant gently and regularly
Don’t scrape the sealant with anything sharp, and don’t stand bottles on the seal.
Damp below or loose tiles need checking quickly. It may be more than a reseal, so we’ll tell you if it needs a builder or plumber.
Questions from Welwyn
What happens after I send photos?
We check the damage, the material and your postcode, then reply with a quote and the next dates we have.
Can I add another job to the visit?
Yes, and it’s often cheaper. Send pictures of everything together and you will get one combined price.
Can you redo someone else’s repair?
Usually, yes. We remove the old repair before doing a new one, so let us know about it.
Are there extra charges for Welwyn?
Travel is included in the price, with the same prices everywhere we work.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.

A little, depending on the job. Open windows and an extractor fan help.

If we find something the photos didn’t show, we explain it first. The price only changes if you agree.
How do I book?
Use the quote form or ring 0345 017 0787, and we will do the rest.
Prices and what affects them
We give every job a fixed price from pictures. This is what makes a difference:
- The material and finish
- How hard the colour is to match
- Previous DIY repairs that have to come out
- The size and number of damaged areas
Our prices are the same across the UK, so there is no premium for Welwyn. What changes the price is the job itself: how much damage, what it’s made of and how many items.
Quotes from your photos
It only takes a minute to photograph the damage. Please include:
- Your postcode, so we can check dates
- The material, if you know it
- A close-up of the damage, in focus
- A wider photo showing the whole bath or shower
Send us a picture of the damage and a wider shot of the entire item, with your AL6 postcode, and we will come back with a fixed quote.
