Facade sealing for commercial buildings in Westbourne
Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. If you have sealant pulling away from frames or panels and weathered facade joints that have lost their grip, we can help, whatever the surface. Searching for sealant specialists in Westbourne? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Construction in a London area such as Westbourne means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Facades, frames and programmes in Westbourne
There are plenty of hotels within about 2 miles of Westbourne. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Westbourne. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
University estates such as Brigham Young University London Centre, less than half a mile south-east of Westbourne, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. For contractors refurbishing units at places like Stable Way Industrial Estate, which lies west of Westbourne, the mastic covers cladding panels, roller-door and window perimeters.

Quoting for work in Westbourne
To price the job, we consider:
- The total length or number of joints
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- The site’s rules and procedures
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Access details, including height
- The site address and postcode
- Specification clauses that apply
- Approximate linear metres or a joint schedule
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Maintenance after handover
To get the most from the new sealant:
- Inspect facade joints on a regular cycle
- Avoid harsh cleaners on facade sealant
- Don’t wait for a second leak before calling
- Check the asbestos register before old mastic is disturbed
Following storms, look inside for damp or staining near frames. An early report normally means a small reseal rather than a bigger repair.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually 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.
FAQs: Westbourne
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly.
Is Stable Way Industrial Estate, near Westbourne, within your area?
Yes. Our area takes in Westbourne and its surroundings, with estates and business parks such as Stable Way Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Which sealant do you use on facades?
The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Is old mastic on our building likely to contain asbestos?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, and we’ll ask to see it. If asbestos is suspected, work stops until it is tested.
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. Nothing else gives a bond that lasts.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

On site: what to expect
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area.

- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Explain the parking and delivery arrangements
- Confirm the product named in the specification

Advice
Common problems we fix in Westbourne
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
If one of these sounds familiar, it’s time for a closer look:
- Previous reseals run over old sealant
- Weathered joints at frame-to-structure perimeters
- Hard, chalky sealant that no longer flexes
- Gaps between rainscreen or cladding panels
Hotel extensions and refits, at places such as New Linden Hotel, which lies south-east of Westbourne, typically run between busy periods, so the sealing is squeezed into short windows.
What your quote should include
