About our bath resealing in South Merstham
The key to a good reseal is getting all of the old silicone out. Fresh sealant doesn’t stick to old, which is why so many DIY reseals peel. Whether it’s black mould in the sealant and gaps in the seal, we can typically put it right, on wet rooms, shower trays & enclosures and baths alike.
We stand behind the work with a one-year guarantee, so you’re covered after the visit.

Work for landlords and builders
Builders use us to fix snagging damage before handover. Several plots can be done in one visit.
For anyone letting property in or around South Merstham, we can repair and quote for several addresses together. Send photos for each one and we’ll price them together.
When a repair is not the answer
We will always be straight with you, so here’s what a repair can’t fix:
- Water damage behind the bath that needs a builder
- Loose tiles, which need refixing first
- Movement in the bath or tray
Send us pictures and we will tell you honestly before booking.
What we work on
- Shower trays & enclosures
- Kitchen worktops & sinks
- Wet rooms
- Basins & vanity units
- Baths
Prices and what affects them
Each job gets its own fixed price. These are the things that affect it:
- Previous DIY repairs that have to come out
- Whether we combine several jobs
- Unusual colours or finishes
- How easy the damage is to reach
We do not add extras on the day. The price we quote from your photos is the price you pay, and if the damage turns out to be different, we discuss it before starting.
Send photos for a quote
Most quotes are done from pictures alone. To help us price it:
- A close-up of the damage, in focus
- One picture of the whole bath or shower
- Daylight if possible, and no flash reflection
- A coin or ruler next to the damage for scale
Call 0345 017 0787 or use the quote form. With one close-up and one wider picture, we can price the job.
What happens on the day
Expect a friendly, tidy visit. We agree the arrival time in advance, cover and mask the work area, and get on with the job, which typically takes around two hours. If anything looks different from your pictures, we will talk to you before going ahead.
- We cut out all of the old sealant.
- We remove the residue and clean the joint.
- Any mould is treated and the joint dried.
- We fill the bath, or weight the tray, to open the joint.
- New mould-resistant silicone is applied and tooled neatly.
Before we arrive
- Mention any parking restrictions or tricky access
- Let us know if it has been repaired before
- Mention if the room is upstairs or in a flat
Getting a price
To get a price, send a couple of photos through our quote form or ring us. We’ll tell you honestly whether it can be repaired.
Advice
Common problems we fix in South Merstham
In time, even good sealant discolours particularly in a well-used bathroom. Steam, soap and movement all take their toll.
Typical reasons for a call-out include:
- Old sealant that looks dirty
- Water getting behind the bath or tray
- Gaps in the seal
- Unsealed corners
Questions to ask before you book
- What prep work is covered
- Whether they match the colour on site
- Whether the price covers travel
- How your room will be protected
Resealing in South Merstham: why it matters
Resealing costs very little, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. Rather than charging by the hour, we price the whole job up front. It depends on the damage, the material and access, and doing several items at once reduces it.
Why choose Surface Doctor in South Merstham
- One visit for most repairs
- Same prices wherever you are
- Honest advice, even when it means no job
- We leave the room as we found it

What your bath or shower is made of matters
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.

South Merstham questions
Will there be a smell?
There can be some smell while we work. It clears as the materials cure.
Do I have to be there?
Yes. The technician needs access to the room for the visit, at a time that suits you.
When can you do it?
Your quote comes with available dates. Tell us if you need it done quickly.
My seal keeps tearing. Why?
Usually because the bath or tray moves. We fill the bath before sealing it.
What if the damage is worse than the pictures show?
If we find something the pictures didn’t show, we explain it first. You decide whether to go ahead.
Can you do more than one item on the same visit?
Yes. Combining jobs on one visit brings the cost down. Send pictures of everything you’d like done.
Are there extra charges for South Merstham?
There’s no separate call-out charge. Your fixed quote includes everything.
Is the work guaranteed?
Yes, for a year. If there’s a problem with the work in that time, we come back and put it right.
Aftercare tips
Much of the damage we repair could have been avoided. These habits help:
- Clean the joints with a mild cleaner
- Run the extractor fan during and after showers
- Keep bottles off the joints
- Open a window after bathing
Use the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.
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.
