How we handle facade sealing in West End
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. If you have discoloured or dirty facade joints and facade joints cracked through the middle, we can help, on coping and flashing joints, perimeter joints where frames meet the structure and cladding panel joints alike. A single leaking joint is often how a building in West End 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.
Around West End, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What the job involves on each surface
Precast concrete panels
Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair before sealing.
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, and mask the edges carefully.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Providing access systems for the work
- Cracked or spalling substrates that need repair before sealing
- Joints whose design needs changing by the specifier
If you’re not sure, just call 01277 525 020 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Stone and brick facade joints
- Coping and flashing joints
- Shopfront frames
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Check the asbestos register before old mastic is disturbed
- Note when each elevation was last resealed
- Share access with other external trades
- Don’t wait for a second leak before calling
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and limits disruption.
Signs you need facade sealing in West End
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.
Look out for the following:
- Leaks at window and door perimeters
- Air leaks through failed facade joints
- Failed sealant on precast panel joints
- Failed seals around shopfront and entrance frames
Extensions at sites like Royal London Hospital for Integrated Medicine (to the north-east of West End) usually sit beside working departments, and the mastic follows strict access rules.

- Whether primer will be used where the manufacturer specifies it
- Will CSCS-carded applicators be on site?
- How joint depth will be controlled
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. 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.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Getting the site ready
- Have the specification and drawings to hand
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed

A 2-mile radius around West End takes in a good number of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. The ULEZ covers the whole of Greater London, West End included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed.
When a college such as Scott's College, less than half a mile north-west of West End, builds or refurbishes, the mastic package typically has to fit around students and staff. Work at a hotel such as The Z Hotel Soho (to the west of West End) tends to be programmed around bookings, mastic included.

FAQs: West End
Can you work on a hospital site such as Royal London Hospital for Integrated Medicine?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you plan work around the academic year at somewhere like University of Notre Dame?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
