Remedial sealant for homes and businesses in North Kensington
Remedial jobs in North Kensington normally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. Typical jobs include sealant peeling off a dusty or damp surface and repeat leaks from the same joint, across expansion joints, leaking tray & enclosure joints and botched or over-sealed joints.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in North Kensington, getting the joints right keeps water where it belongs and the room looking clean.
Big or small, you get the same one-year guarantee.

Quotes for remedial sealant in North Kensington
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- Whether the work is at height
- How many areas need sealing
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work.
Why act early in North Kensington
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in North Kensington.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why us?
- Over 20 years’ experience
- Neat joints and a tidy finish
- Anti-fungal silicone where joints get wet
- Homes, businesses and hotels

Surface by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing stops that, so the sealant grips the two sides only.
When it is not the sealant
A few problems are outside what sealant work can do:
- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
- Sealant in an older building that needs testing for asbestos first
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.
Surfaces we seal
- Expansion joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints

Bathrooms and kitchens in North Kensington
London has hard water, so limescale builds up on sealant, grout and fittings. There are hotels and other places to stay in and around North Kensington. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
If you let a flat or house near Kensal Green station, a joint that keeps failing is best fixed properly while the property is empty. In the older streets around Dissenters' Chapel, walls and floors in older homes can move, and sealant and grout show it first.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many layers have to come out, and the area is left clean. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in North Kensington. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can

Do you need remedial sealant in North Kensington?
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
Most people get in touch after spotting one of these:
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
- Floor or wall movement joints that have failed
- Caulk or the wrong sealant used in a wet area
Managing a site like Barlby Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

- Whether they’re fully insured
- What preparation is included

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
