Commercial sealant contractors in Westbourne, done properly
If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Westbourne, ring 01277 525 020 or use the quote form with the site addresses. Site teams most often ask us about layers of sealant, all of them failing and window and door perimeter joints that have cracked open, across window and door perimeters, movement joints in walls and floors and external facade joints. A specialist sealant contractor works differently from a general builder: on jobs in Westbourne, preparation and product choice get the time they need.
Occupied buildings in Westbourne need the work phased: washrooms in turn, floors in sections and entrances kept open.
Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Surface by surface
Fire-rated seals where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, and we will tell you if the detail calls for something else.
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.

What else we do in Westbourne
What Westbourne’s businesses ask us to seal
The 3 miles around Westbourne take in at least three named trading estates, business parks or retail parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it. A 2-mile radius around Westbourne takes in plenty of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet; work is planned so the hotel keeps trading.
Trade counters and showrooms on estates such as Stable Way Industrial Estate (1.1 miles west of Westbourne) need neat joints where clients see them. For a hotel such as New Linden Hotel (less than half a mile south-east of Westbourne), the colour of a joint at the bar or the bath matters to the look of the room.
Westbourne is about 1 mile north of Kensington, in Greater London. Across the W2 postcode area, 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, from busy centres to rural villages.
Commercial sites across W2, W11 and W9 are covered for sealant joints. Buildings on Salem Road, Acklam Road and Morgan Road are within our area. You will find Westbourne on or near the A404 and A4206, so getting applicators and materials to site is simple. We also cover Westbourne Green (1 mile north-east), Bayswater (1 mile south), Little Venice (1 mile north-east), Maida Vale (1 mile north) and Paddington Green (1 mile east). Bigger towns within reach include London (5 miles east), St Pancras (3 miles east), Shoreditch (5 miles east), Walthamstow (9 miles north-east), Hoxton (5 miles east) and Whitechapel (5 miles east).
Around Westbourne
Locally, jobs take us to sites close to Maida Vale School, Abdus Salam Library and Westminster Academy. Also close by are Emslie Horniman's Pleasance (0.8 miles north-west) and Cock and Bottle pub (under half a mile south-west). The nearest railway station is London Paddington station, roughly 0.8 miles east. Nearby you’ll also find Paddington General Hospital (0.5 miles north) and Greek Orthodox Cathedral Treasury Museum (under half a mile south-east). Green spaces nearby include Campden Hill and Greville Place nature reserve.
Common problems we fix in Westbourne
The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason.
Look out for the following:
- Gaps behind commercial kitchen worktops and sinks
- Sanitary sealant that has gone black and patchy
- Layers of sealant, all of them failing
- Untidy joints in a reception, shop floor or lobby
Units at places like Kensington Arcade, 1.1 miles south of Westbourne, are refitted as brands change, and the joints have to suit each new scheme.
Questions to ask before you book
- Can the work be phased to keep areas open?
- How the joint faces will be prepared and primed
- Who will actually carry out the work
- Proof of insurance
After the work
Once the work is signed off, these steps help:
- Have extract fans checked so wet areas dry out
- Check the asbestos register before anyone disturbs old sealant in an older building
- Check sealant as part of routine building inspections
- Note dates and locations of sealant work for future planning
Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Structural cracks or movement the joints weren’t designed for
- Roof leaks that only look like a joint problem
- Old mastic that tests positive for asbestos
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.
Joints and surfaces we work on

Questions we’re asked in Westbourne
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Do you cover business parks and estates near Westbourne, such as Stable Way Industrial Estate?
Yes. Estates, retail parks and business parks around Westbourne, Stable Way Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Can you take on work for an FM or managing agent?
Yes. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
From enquiry to sign-off
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 we finish with a walk round so the work can be signed off. All of Greater London is in the ULEZ, and kerbside space in Westbourne can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
What we need from you
- Make sure the joints can be reached
- Tell us what induction or permit system the site runs
- Point out parking and an unloading spot

Advice
Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
