What affects the quote in Kensington
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating
- How easy the joints are to reach
- The old material and how stubborn it is
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.
What to tell us for a quote
When you call or email, it’s useful to know:
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- Roughly how big the job is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Commercial sealant in Kensington, done properly
Landlords and agents with several properties can have bathrooms and kitchens resealed between tenancies. Several addresses can be quoted together. Common call-outs are for split sealant around staff kitchen worktops and sinks and whole floors of tired en suites, across rental portfolios, retail & leisure sites and student & care accommodation.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Kensington, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Each job carries a 12-month guarantee, large or small.

Different surfaces, different methods
Rental portfolios
A sound seal protects the property as well as its appearance.
Retail & leisure sites
Gym and leisure changing rooms take heavy use and plenty of water, so joints are sealed with anti-fungal sanitary silicone.
What happens on the day
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of rooms, and we explain the cure time before we leave. In Kensington, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

What else we do in Kensington
Kensington: your questions answered
Is parking an issue for commercial sealant in Kensington?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Kensington Olympia station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do you come to Kensington?
We do. Kensington is part of the area we cover.
When can guests or staff use the shower again?
Follow the cure time we give you, which is generally around 24 hours. A room-by-room programme keeps only a few rooms out at once.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
What does commercial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Commercial sealant around Kensington
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. London’s water is hard, which leaves limescale on sealant, grout and taps.
As a London address, Kensington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you look after a church, hall or community building such as Church of St Barnabas, halls and community kitchens see heavy use, and their sealant shows it.

What happens if it’s left?
Patching the worst rooms as complaints come in is hard to manage. A planned programme deals with every room in order, with less disruption and one clear quote. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Kensington, the repair is bigger than a sealant job.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why us?
- Approved under the ARBOMaster scheme
- White, clear, grey or coloured to suit, where the product allows
- 12-month guarantee on every job
- We’re fully insured
See our cost guide or our reviews.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Tell cleaning staff when each room can be used
- Put a squeegee in each shower
- Plan resealing around quiet periods
- Add sealant to your planned maintenance checks
Each room is handed back with its cure time, which is usually around 24 hours. Make sure housekeeping or cleaning staff know it so nobody showers or cleans the joint too early.
Black sealant in a staff washroom or guest bathroom draws complaints. The longer it’s left, the deeper it grows into the silicone, so the fix is replacement.
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
We also work for property managers and facilities teams in Kensington and across Greater London. Several sites can be quoted together.
When to call us in Kensington
In an accessible wet room, water spreads across the floor every use, so floor-to-wall joints take standing water. Any split there can let water through quickly.
People generally contact us when they notice one of these:
- Leaks from showers into rooms or ceilings below
- Too many rooms to reseal without closing the building
- Failed joints in office kitchens and tea points
- Split sealant where wet room floors meet walls
For site and facilities teams at buildings such as St Barnabas and St Philip's CofE Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.
Before you book anyone
- How the colour is chosen
- Is the old sealant removed completely?
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
