Bath & shower resealing (mastic) in Cottam, Nottinghamshire
Our repair technicians come to Cottam for bath, shower and sink resealing with new mould-resistant silicone. Nothing is taken out, and the work is guaranteed.
- Black spots in the silicone
- Damp near the bath
- Silicone coming away from the tiles

DIY kit or professional repair?
For a hairline mark somewhere you will never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
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.
About our bath resealing in Cottam
Resealing is one of the simplest ways to protect your bathroom. Failed sealant lets water get where it shouldn’t, and resealing puts a stop to that. We work on basins & vanity units, baths and shower trays & enclosures, and people most often call us about silicone coming away from the tiles and a messy previous reseal.
We guarantee the work for a year. If there is a problem with the repair within the year, we return and sort it.

FAQs for Cottam
How long before I can shower?
We will give you the curing time.
Do the materials smell?
It depends on the job, but frequently a little. Ventilation keeps it to a minimum, and it soon fades.
How long does a reseal take?
A bath or shower normally takes a couple of hours. It then needs time to cure.
Can you repair something that’s been repaired before?
Most of the time. Let us know what was used before.
When can you do it?
We will give you dates with your quote. Tell us if you need it done quickly.
Are you accredited?
We are accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
Can tenants book a repair?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Why does the silicone keep cracking?
Something is moving. If it keeps happening, the support may need fixing.
Prices and what affects them
You will not pay by the hour. The price is based on:
- The size and number of damaged areas
- The colour and finish to match
- The material
- Whether we combine several jobs
No two jobs are quite the same, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.
Getting a price from pictures
Before you send photos, these tips help us give you a firm price:
- The material, if you know it
- The postcode, so we can plan the visit
- Good light, ideally daylight, without flash glare
- One picture of the whole bath or shower
Email us a photo of the damage and one of the entire item, with your DN22 postcode, and we will come back with a fixed quote.
What we are called out for in Cottam
Joints split if the bath or tray moves, often because it was sealed while the bath was empty.
Common reasons people in Cottam contact us are:
- Unsealed corners
- Sealant that’s split or lifting
- Old sealant that looks dirty
- An untidy old seal
Questions to ask before booking
- Whether they match the colour on site
- Whether the price is fixed and includes VAT
- What happens if the damage is worse than the pictures show
- How long the guarantee is and what it covers
How the visit works
It’s a tidy, low-fuss visit. We confirm the time with you beforehand, protect the area, and get on with the job, which normally takes around two hours. If we find something your photos didn’t show, we’ll explain it before carrying on.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- We fill the bath, or weight the tray, to open the joint.
- New mould-resistant silicone is applied and tooled neatly.
Getting ready for the visit
- Keep pets and children out of the room while we work

Advice
How to look after the repair
Aftercare is simple:
- Replace the seal when mould sets in
- Do not stand toiletries on the seal
- Wipe the joints dry after use
- Clean the joints with a mild cleaner
Avoid scraping the joints, and keep shampoo bottles off the joints.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, so we’ll tell you if it needs a builder or plumber.
Materials and what they mean for the repair
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Baths
Baths are resealed with water in them, to open the joint fully.
Resealing in Cottam: why it matters
A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. Set against the cost of replacement, a repair is normally a fraction of the price, because nothing has to be taken out, refitted or made good. The quote lists exactly what you’re paying for.
Why choose Surface Doctor in Cottam
- Every repair guaranteed for a year
- Nothing taken out or refitted
- Rooms protected and left tidy
- One visit for most repairs
