How we handle bathroom resealing in Westcombe Park
With over 20 years in the trade, we reseal baths, showers and kitchens in homes across Westcombe Park. We are ARBOMaster approved and fully insured, and every job carries our one-year guarantee. We work on kitchen worktops & upstands, sinks & splashbacks and shower trays & enclosures, and common reasons people get in touch are damp behind the bath or under the tray and a joint torn by a bath that flexes.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Westcombe Park more than a cosmetic job.
Your job is guaranteed for a year, as with all our work.

Baths
The long joint down the side of a bath is where most leaks start, especially under a shower. It gets one smooth bead of anti-fungal silicone.
Basins & vanity units
The back of a basin gets wet every time someone washes. Old sealant there often goes black at the corners, so it’s cut out and renewed just like a bath joint.
What happens if it’s left?
Fresh sealant smartens a bathroom or kitchen with very little disruption, which matters if you’re letting a property or selling it. A smeared, uneven DIY bead does the opposite, and it’s harder to put right later. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start.

When to call us in Westcombe Park
No sealant lasts indefinitely. Every shower, every splash and every wipe with a cleaner slowly wear it down, and how long it lasts comes down to use, cleaning and ventilation.
Look out for any of the following:
- Leaks into the floor or ceiling below
- Sealant that has split, shrunk or peeled away
- Black spots spreading through the bead
- Water escaping at the shower enclosure
For an older house near a landmark such as St George's Church, older homes can move a little, which is hard on rigid grout and tired sealant.
Questions to ask before booking
- Is VAT in the price?
- When the joint can take water or movement
- Are they insured?
- Whether they seal over old material or remove it

Westcombe Park questions
Do you work in hotels near Westcombe Park?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Can parking be tricky for a visit in Westcombe Park?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long does it take to reseal a bath or shower?
It takes half a day or less for one room, longer when the kitchen is included. We’ll confirm how long your job needs when we quote.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
How much does bathroom resealing cost in Westcombe Park?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Aftercare tips
After the cure time, these simple habits help:
- Keep bottles off the sealant line
- Keep the fan on for a while after bathing
- Use gentle cleaners on the silicone
- Dry worktop joints after washing up
Do not stand bottles along the bead, as they hold water against it. Squeegeeing the walls and tray after use keeps water from sitting on the joint.
Small signs come before a leak: a corner lifting, a gap behind the bead, a dark line under the silicone or a damp patch on the ceiling below. If you spot one, it’s time to reseal.
The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes two to three hours for a typical bath, depending on how much old sealant there is. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by protecting the area and stripping out the old bead, including the film left on the tiles.
- We clean and degrease the joint and treat any mould.
- The joint is left to dry, and baths are filled with water first.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We tidy up and give you the cure time, generally around 24 hours.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
- Keep children and pets away from the work area
