Bath & shower resealing (mastic) in South Harrow, Greater London
We travel to South Harrow for bath, shower and sink resealing with new mould-resistant silicone. Everything is done in place, and the work is guaranteed.
- Missing sealant behind the taps
- Water getting behind the bath or tray
- Discoloured, yellow sealant
Can I fix it myself?
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. Just mention it when you send photos, as it can add time.
If you do try a kit, read the instructions carefully, ensure the area is clean and completely dry, and give it the full curing time. If it doesn’t work out, we can still repair it properly.
Bath resealing in South Harrow without replacing anything
A good reseal is all about preparation: every bit of old silicone out, mould treated, the joint clean and dry. Then the fresh sealant goes on, in a neat, continuous bead. We work on kitchen worktops & sinks, baths and shower trays & enclosures, and common reasons people contact us are missing sealant behind the taps and an untidy old seal.
All of our repairs are guaranteed for twelve months in South Harrow and everywhere else. We return to put right any problem with the work.

Common problems we fix in South Harrow
Even good sealant eventually discolours particularly in a well-used bathroom. Steam, soap and movement all take their toll.

Why reseal now?
Resealing is a small job. Leaving split or mouldy sealant can let water reach the walls and floor, which costs far more to put right. We charge the same wherever you are, so there is no premium for South Harrow. What changes the price is the job itself: the material, the amount of damage and how many items.
Why book with us
- Dust sheets down, tidy finish
- Technicians who travel to you, UK-wide
- We’ll tell you if it’s not worth repairing

For landlords and businesses
Landlords, letting agents and housing providers in South Harrow use us as well as homeowners. Repairing between tenancies keeps void periods short, and it costs much less than replacing.
Letting agents frequently send us photos straight from the inventory. That means we can quote before you even visit the property, and we liaise with tenants about access if you’d like us to.
Prices and what affects them
A fixed quote means you know the cost before you book. We look at:
- Whether it’s a chip, crack, burn or wear
- How hard the colour is to match
- What the surface is made of
- Access to the area
Compared with replacing, a repair is typically a fraction of the price, because there is no removal, plumbing or making good. Your fixed quote shows exactly what’s included.
Quotes from your pictures
Before you send photos, a few simple things make all the difference:
- The material, if you know it
- Any earlier repairs or coatings
- A coin beside the damage so we can judge size
- A wider photo showing the entire bath or shower
A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, add your postcode and send them over. You will get a fixed quote, not an estimate.
How the visit works
On the day, we arrive at the time we have agreed, cover the area with dust sheets and masking, and set to work. The job generally takes around two hours. We tidy up before we leave and tell you when it’s ready to use.
- We cut out and remove all of the old sealant.
- The joint is cleaned and any mould treated.
- We make sure the joint is completely dry.
- Baths are filled with water first, so the joint is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, including around the taps.
Before we arrive
- Tell us about parking, stairs or access
- Keep a parking space free if you can
- Avoid using the area for a few hours before we arrive

How to look after the repair
It’s all simple stuff:
- Air the room after use
- Dry the seal after bathing
- Give the seal a regular clean
- Store bottles on a shelf
Avoid scraping the joints, and keep shampoo bottles off the joints.
Black mould in sealant is not just unsightly. Resealing early keeps water out of the walls and floor.
