How we handle construction mastic in Brompton
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal sealing often fills those days. If you have a mastic package split between trades with no clear owner and perimeter gaps outside the sealant’s range, we can help. For commercial sealant work in Brompton, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Building sites in London tend to be tight: 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.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Maintenance after handover
A few simple habits keep the new joints working:
- Don’t schedule sealing before decorators and flooring are done
- Plan external elevations with the weather in mind
- Keep finished joints away from paint, plaster and scrapers
- Check frame gaps are within the sealant’s range before sealing
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
One unsealed frame can let water into finished internal areas. That normally means redoing finishes in a completed area and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes whatever the programme allows, since the work follows the trades as areas are released. For a job in Brompton, access comes first. Send the building rules and access times with your enquiry.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready
- Move anything stored against the joints
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed

Sites and facades in and around Brompton
Site traffic in Brompton falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. The area within 2 miles of Brompton holds plenty of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
For contractors at a college like St Mellitus Theological College (1 mile west of Brompton), perimeters and internal sealant are timed for the holidays. Work at a hotel such as The Beaufort Hotel, less than half a mile to the north of Brompton, tends to be programmed around bookings, mastic included. Units on estates such as Brompton Cross District Shopping Centre. (less than half a mile west of Brompton) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

What happens if it’s left?
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple. In Brompton, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
