Construction mastic near Kensal Rise
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Glazing units that are cracked or misted
- Frame gaps too wide for sealant, which the installer needs to correct
- Joint design decisions that belong to the architect or engineer
Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly before you book.

Construction mastic in Kensal Rise
Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We work on internal decorators’ caulk, floor and skirting junctions and sanitary and kitchen joints, and the usual reasons a site gets in touch are failed sealant in an existing building being refurbished and bath and shower joints scraped during the final clean. Most enquiries from Kensal Rise start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Construction in a London area such as Kensal Rise means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Check frame gaps are within the sealant’s range before sealing
- Don’t force external sealing on a damp or frosty day
- Put any product change through the designer first
- Share drawings and the specification as soon as possible
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
Different surfaces, different methods
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere.
Construction mastic in Kensal Rise: the local picture
The ULEZ covers the whole of Greater London, Kensal Rise included, so site vehicles need to meet its standards or pay the daily charge. Delivery slots and scarce storage shape how and when the mastic goes in. Kensal Rise has plenty of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
When units on a site such as The Quadrant Business Centre, 0.6 miles north-east of Kensal Rise, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For contractors on a campus like Imperial College London (1.3 miles south of Kensal Rise), facade and perimeter sealing has to fit around students and term dates.
Kensal Rise is about 1 mile south-west of Kilburn, in Greater London. Anywhere in W10, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places. For work in that direction, see our London page.
If you need construction mastic in W10, NW10 and NW6, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Hazel Road, Hiley Road and Kempe Road are within our area for mastic packages. If your building is just outside Kensal Rise, we cover Kensal Green (1 mile west), Kilburn (1 mile north-east), Queen's Park (1 mile east), North Kensington (1 mile south) and Kensal Town (1 mile south-east). Further afield, our area takes in London (6 miles south-east), City of Westminster (3 miles south-east), Marylebone (3 miles east), St Pancras (4 miles east), Shoreditch (6 miles east) and Walthamstow (9 miles north-east).

FAQs: Kensal Rise
Can you take on a job at a hospital such as St Charles' Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you work around term dates at a campus such as Imperial College London?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you come in just for snagging?
Yes, we can. Share the list and photos, and a fixed quote follows.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you do internal caulk as well as external mastic?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging, all priced as one package.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

When to call us in Kensal Rise
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
It’s worth sending us details if you spot any of the following:
- Mastic snags holding up handover
- Frame gaps too wide for sealant alone
- Bath and shower joints scraped during the final clean
- Window and door perimeters that won’t pass inspection
Hotels like Igar Hotel (to the north-east of Kensal Rise) rarely close for long, so refurbishment mastic is phased floor by floor.
What your quote should include
- Their pre-qualification and accreditations
- The named product and why it was chosen
- Who will actually carry out the work
- How long is the guarantee, and what does it include?
What happens if it’s left?
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification. Called in at the end, the same issues surface during handover. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
