Facades, frames and programmes in Brockley
Site traffic in Brockley falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are a good number of hotels within about 2 miles of Brockley. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For contractors at a school such as Beecroft Garden Primary, sealing has to be finished before term starts. Projects at colleges like Christ the King: Aquinas Sixth Form College, 1 mile to the north of Brockley, tend to run to term dates, so the mastic is planned tightly.

Facade sealing in Brockley
Facade sealants sit in the sun, rain and frost every day, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. Site teams most often ask us about air leaks through failed facade joints and old perimeter mastic that has dried out, on coping and flashing joints, window and door perimeters and perimeter joints where frames meet the structure. A specialist sealant contractor works differently from a general builder: on jobs in Brockley, preparation and product choice get the time they need.
Around Brockley, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Keeping the joints sound
After handover, a little attention goes a long way:
- Inspect facade joints on a regular cycle
- Investigate damp beside windows promptly
- Keep pressure washers away from fresh sealant
- Avoid patch repairs on failed facade joints
Following storms, look inside for damp or staining near frames. An early report usually means a small reseal rather than a bigger repair.
Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Water getting in through cracked render or porous masonry
- Movement beyond what any sealant can handle
- Replacing glass or failed glazing units
If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Site staff or a sealant specialist?
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What we are called out for in Brockley
Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.
If one of these sounds familiar, it’s time for a closer look:
- Staining on stone next to old sealant
- Damp patches beside frames after rain
- Weathered joints at frame-to-structure perimeters
- Gaps between rainscreen or cladding panels
For contractors on a campus like University of Greenwich - Greenwich Campus (2.3 miles north-east of Brockley), facade and perimeter sealing has to fit around students and term dates.
What your quote should include
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
- The named product and why it was chosen
- How long is the guarantee, and what does it include?

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Point out parking and an unloading spot
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed

Common questions from Brockley clients
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.
Could you schedule work at a campus like University of Greenwich - Greenwich Campus for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Should we check old sealant for asbestos?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed. We don’t remove asbestos-containing materials.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
How long do sealant joints last?
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.
