Block-wide mastic in Notting Hill
Blocks in London are normally run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We plan around the notices and access you arrange.
Trustees of buildings like St John's Notting Hill can bring frame and external mastic into a planned maintenance list. Buildings close to stations like Shepherds Bush station (to the south-west of Notting Hill) are often flats over shops, with frame mastic to keep sound.
Notting Hill is about 1 mile north of Kensington, in Greater London. We cover Notting Hill and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Our Greater London coverage takes in 764 places, large and small.

Mastic sealing in Notting Hill, done properly
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. The enquiries we see most involve repeated reactive repairs to the same buildings and damaged joints in communal entrances and corridors, across communal kitchens and washrooms, external wall and movement joints and window and door perimeters on blocks. Facilities teams, main contractors and managing agents in Notting Hill tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In a London area such as Notting Hill, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time, which is why block-wide programmes make sense.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What affects the price in Notting Hill
What shapes the price:
- Whether old sealant has to be cut out first
- Travel to remote or island sites
- The site’s rules and procedures
- How accessible the joints are
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- Specification clauses that apply
- The postcode of the building
- Drawings or a marked-up plan, if available
- The type of building and who uses it
To get a fixed quote, phone 01277 525 020 or email the details over with the site address and an outline of the work. You can also send details through our quote form.
When to call us in Notting Hill
Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. We’ll tell you if the joint edges need repairing before resealing.
Things that typically lead to an enquiry:
- The same joint failures repeated across a portfolio
- Cracked, hardened mastic round windows on a block
- Repeated reactive repairs to the same buildings
- Open joints in brickwork or panels
Schools and community buildings such as St Clement and St James CofE Primary School need frame and external mastic kept sound like any building.
Questions to ask before you book
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
- Whether primer will be used where the manufacturer specifies it
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Let us know about inductions and permits
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000

Advice
Common questions from Notting Hill clients
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
Do you work for managing agents with blocks near Shepherds Bush station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
Commercial clients in Notting Hill
Building owners and managing agents use us on everything from one building to a spread of sites around Notting Hill. Several sites can go on one quote, which keeps the paperwork simple.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Keeping the joints sound
For the best life from the joints:
- Protect low-level joints in entrances
- Keep a record of when each building was resealed
- Have the asbestos survey to hand for older buildings
- Prioritise elevations facing the weather
Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
What happens if it’s left?
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure with less control over timing. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
