Sites and facades in and around Kensal Green
The area within 2 miles of Kensal Green holds a good number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. As part of Greater London, Kensal Green is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
Building work at universities like Imperial College London (to the south of Kensal Green) is often timed for the summer, mastic included. Units on estates such as Mitre Bridge Industrial Estate (0.5 miles south-west of Kensal Green) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Kensal Green is about 1 mile south-west of Kilburn, in Greater London. We send applicators to Kensal Green for facade joints, handled exactly as we handle every other area. 764 places across Greater London fall within our area, Kensal Green among them. Sites around London have their own page, about 6 miles away.

Facade sealing in Kensal Green
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Kensal Green. Coping and flashing joints are included where sealant is the specified fix. We work on perimeter joints where frames meet the structure, cladding panel joints and window and door perimeters, and the failures we’re asked to look at most are sealant pulling away from frames or panels and air leaks through failed facade joints. A single leaking joint is often how a building in Kensal Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in a London area such as Kensal Green 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.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Questions we’re asked in Kensal Green
Do you take on jobs in Kensal Green where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry.
Do you take on work at healthcare sites like St Charles' Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months on every job.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you look at water coming in around a frame?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we will tell you which.
Is Kensal Green in your area?
Yes. Kensal Green falls within our area, and you can phone 01277 525 020 or send photos by email to get started.
What sets the cost
We price every job individually. The main factors are:
- Backing rod, priming and other preparation
- Working within restricted access windows
- The site’s rules and procedures
- Location, for remote and island sites
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- Your programme or deadline
- The type of building and who uses it
- Any specification or named product
- Asbestos survey details if the building is older
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or send photos by email.
Aftercare for building managers
After handover, these steps help:
- Clear debris that holds water against joints
- Insist on a full cut-out when joints are renewed
- Ask about asbestos in pre-2000 mastic
- Record the product and colour used on each elevation
Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Leave it or put it right?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

How a job runs
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
- Let building users know which areas are affected
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

What we’re called out for in Kensal Green
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building.
Site and facilities staff are often the first to spot these:
- Patch repairs that keep failing
- Damp patches beside frames after rain
- Staining on stone next to old sealant
- Cladding panel joints that have opened up
Hospital estates such as St Charles' Hospital (0.7 miles south-east of Kensal Green) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Before you book anyone
